intelligent robots and computer vision XV: algorithms, techniques,Active vision, and Materials Handling

The challenging task of automated handling of variable objects necessitates a combination of innovative engineering and advanced information technology. This paper describes the application of a recently developed control strategy applied to overcome some limitations of robot handling, particularly when dealing with variable objects. The paper focuses on a novel approach to accommodate the need for sensing and actuation in controlling the pickup procedure. An experimental robot-based system for the handling of soft parts, ranging from artificial components to natural objects such as fruit and meat pieces was developed. The configuration comprises a modular gripper subsystem, and an industrial robot as part of a distributed control system. The gripper subsystem features manually configurable fingers with integrated sensing capabilities. The control architecture is based on a concept of decentralized control differentiating between positioning and gripping procedures. In this way, the robot and gripper systems are treated as individual handling operations. THis concept allows very short set-up times for future changes involving one or more sub-systems.

Proceedings of the 1998 Conference on intelligent robots and computer vision XVII: algorithms, techniques, and Active vision

作者： Carbon, Margarita A. Boeing Co Canoga Park CA United States

Diffraction of light by 3D phase grating layers could be effectively used for color image processing in robotic vision. Gratings with hexagonal close-packed structures have the maximum amount of cells per volume unit, which leads to an advantage for color image processing. Using the 4D spectral method, we solve the wave equation for diffraction of light by a 3D hexagonal phase grating layer of spherical particles. Both ABCA and ABAB structures are considered. Distribution of diffracted light intensity is calculated in the Fraunhofer and Fresnel diffraction zones. For particular gating distances, the incident white light diffracts in three spatially separated maximums with the central wavelengths corresponding to the three primary colors. The wavelength dependence of diffracted light intensity, for incident white light, is calculated for the three maximums. In general case, by using these three primary curves one can reconstruct the color of incident light from corresponding values of light intensities measured in the three diffracted maximums. The conditions for self-imaging of 3D grating layers are formulated and investigated. Intensity distributions for diffracted light in planes of positive and negative self-imaging, and in a plane of lowest contrast are computed.

This paper focuses on simulating a model of 3D-color vision system based on synthetic nonlinear modulation. The model is set up to recover 3D and color properties from a colored object through evaluating several rf-interferograms sampled by a black-white CCD camera. Colorizing a black-white CCD camera in a 3D-vision system implies high resolution. The synthetic nonlinear modulation is different from other 3D-color vision systems. Different colored lights are synchronously modulated with characterizing rf-frequencies to detect a 3D object. Recovering colors is equally treated as recovering 3D information. Optical filters are not used. Instead, a suitable algorithm is adopted for recovering color and 3D information. Since a modulated optical rf-signal is used as a detecting probe rather than an unmodulated optical wave, higher orders of harmonic signals may be caused by electrical or optical components. Although linear matching techniques are adapted to prevent the problem, it is necessary to simulate the vision system for predicting its performances. An 8-bit black-white CCD camera with different signal to noise ratios is taken as an example in the simulation. 3D color properties are evaluated for the system in the case of nonlinearity and noise. An optimized result is obtained for realizing this vision system.

Boundary-based shape normalization technique

Boundary-based shape normalization technique

intelligent robots and computer vision XI: algorithms, techniques, and Active vision

作者： Leu, Jia-Guu Wayne State Univ. Detroit MI USA

ISBN: (纸本)0819410268

When a camera's center axis is not parallel to the surface normal of a planar object, the perceived shape of the object will be skewed. Most existing shape analysis methods are sensitive to such shape distortions. That is, if a shape is skewed due to non-orthographic projection, it may not be correctly recognized. In this paper we present a shape normalization process which neutralizes such shape skewing effects. In our case, a perceived shape is represented by a list of corner points along its boundary. We first compute the six lower moments of the shape from its boundary. Then these moments are used to compute the shape's center location, orientation, and maximum and minimum moments of inertia. To normalize the shape we first translate the shape's center to the origin. Next we rotate the shape to align its major axis with the x-axis. Then we expand the shape along its minor axis to neutralize shape skewing. Lastly, we scale the size of the shape so it has a standard moment of inertia. The suggested method can be used as a preprocessing step for any planar shape analysis method which is sensitive to shape skewing, shape size change, and/or shape translation. Since the moments are computed from the shape's boundary instead of from all its interior pixels, the method is also efficient. Several experimental results are given to show the effectiveness of the approach.

Design of large-window binary filters via iteration

Design of large-window binary filters via iteration

Proceedings of the 1998 Conference on intelligent robots and computer vision XVII: algorithms, techniques, and Active vision

作者： Hirata, Nina S.T. Dougherty, Edward R. Barrera, Junior Universidade de Sao Paulo Sao Paulo Brazil

Rather than design an optimal filter over a large window, which may be computationally impossible or require unacceptable computation time, one can design an iterative filter, each stage of which is designed over a small window with acceptable design time. Theoretically, a two-stage iterative filter with each stage optimally designed over a window is suboptimal in comparison to the optimal filter over the larger window formed as the dilation of the small window with itself. In practice, however, filters are designed from realizations and lack of precision for design over a large window can result in a directly estimated optimal filter over a large window that performs worse than an iteratively designed filter. Using image-noise models, this paper considers three cases: (1) the designed filters are good estimates of the theoretically optimal filters, the two-stage iterative filter is close to optimal, and as further iterations are considered for both the small and large windows, the performance difference becomes small;(2) the designed filter over the large window is a poor estimate of the theoretically optimal filter and the iteratively designed filter outperforms the directly designed filter;(3) iteration cannot do well because the iteration window is too small for the image-noise model. We will see that, while in terms of logic there may be a significant difference between a noniterative and an approximating iterative filter, their probabilistic difference as operators on random processes can be negligible.

Calibration of the spherical pointing motor

Calibration of the spherical pointing motor

intelligent robots and computer vision XI: algorithms, techniques, and Active vision

We have built a new miniature pan-tilt actuator, the spherical pointing motor (SPM). The SPM is an absolute positioning device, designed to orient a small camera sensor in two degrees of rotational freedom. The basic idea is to orient a permanent magnet to the magnetic field induced by three orthogonal coils by applying the appropriate ratio of currents to the coils. The function describing the relation between the coil currents and the resultant motor position can be calculated, but it is not very accurate as the actual coils do not exactly satisfy the assumptions made in these calculations. The motor must be calibrated to find the coil currents accurately. This paper describes a procedure for automatic calibration of the SPM. It is based on image feedback from a camera returning space-variant images, mounted on the rotor of the motor. It assumes that a calibrated image sensor and lens are used, i.e., that it is known how many degrees each pixel subtends. It also assumes that the camera rotates about its focal point. The calibration algorithm uses a scene of black dots on a white background. For each motor position that is to be calibrated, the algorithm moves the motor approximately to that position using the calculated currents. The algorithm analyzes the image, and uses the position of the relevant dot to calculate the actual position of the motor. It then associates this position with the coil currents and stores it in a look-up-table. Finally, we interpolate between calibrated points to move to other positions.

A main goal of robotics is to impart in machines an ability to intelligently interact with their environments. In this study we present a system (and an implementation of it) which evaluates the compatibility between objects and specific goal oriented action requirements for carrying out hand-actions. The system is an extension in the framework of fuzzy sets and possibility theory of our model of functional recognition of objects. The system operates on a hierarchical description of objects and action requirements which are mapped into a functional compatibility domain. We show that what computations are actually carried out by the algorithm depends on the application. When the system is used for inspection, it probably knows the identity of the object and its task is only to verify whether the object is in a state that allows its use in the prototypical action for which it has been designed. When the system is used for categorization purposes it needs to identify the existence of features compatible with the action requirements and it verifies that features which prevent carrying out the action cannot be identified. This latter case is particularly interesting and computationally challenging since the system is asked to compute the auxiliary, or possible functions of an object in addition to the prototypical function. The computation of the auxiliary functions relies on the description of the object's parts and subparts.

The paper introduces a fast and enhanced recovering algorithm and its application in an active 3D-color vision system. The algorithm is based on the processing of several non-linearly modulated optical test signals of different colors. The processing approach arises from minimizing errors caused by using non-linear modulators in an active vision system, i.e., recovering 3D properties from higher order terms of a Fourier series expansion of the non-linear modulation. Two aspects are worth mentioning: Firstly, the modulation depth of non-linear optical components such as Pockels cells can be exploited much beyond the linear region if assisted by the appropriate recovering algorithm and thus increasing the effective aperture of the optical system. Secondly, the same algorithm can be adaptive to a synthetic non-linear modulation, i.e., the various incoherent signals used as color probes are synchronously modulated each with different characterizing rf signals by means of corresponding optical modulators. These signals are then further incoherently superposed in the transmission medium. After having been reflected from and interacted with the object of interest, the selectively attenuated signals are demodulated using a single modulator. In this process phase, color and other information are simultaneously demodulated. Therefore a single black-white CCD camera may be utilized to sample the 2D-rf interferograms, which are fast and analytically processed by the proposed algorithm in order to extract 3D ranges, colors, and other properties of the interesting object.

Biologically plausible model of the system with an adaptive behavior in a priori environment and resistant to impairment has been developed. The system consists of input, learning, and output subsystems. The first subsystems classifies input patterns presented as n-dimensional vectors in accordance with some associative rule. The second one being a neural network determines adaptive responses of the system to input patterns. Arranged neural groups coding possible input patterns and appropriate output responses are formed during learning by means of negative reinforcement. Output subsystem maps a neural network activity into the system behavior in the environment. The system developed has been studied by computer simulation imitating a collision-free motion of a mobile robot. After some learning period the system 'moves' along a road without collisions. It is shown that in spite of impairment of some neural network elements the system functions reliably after relearning. Foveal visual preprocessor model developed earlier has been tested to form a kind of visual input to the system.

intelligent robots and computer vision XIV: algorithms, techniques, Active vision, and Materials Handling

ISBN: (纸本)0819419524

Active sensing is the process of exploring the environment using multiple views of a scene captured by sensors from different points in space under different sensor settings. Applications of active sensing are numerous and can be found in the medical field (limb reconstruction), in archeology (bone mapping), in the movie and advertisement industry (computer simulation and graphics), in manufacturing (quality control), as well as in the environmental industry (mapping of nuclear dump sites). In this work, the focus is on the use of a single vision sensor (camera) to perform the volumetric modeling of an unknown object in an entirely autonomous fashion. The camera moves to acquire the necessary information in two ways: (a) viewing closely each local feature of interest using 2D data;and (b) acquiring global information about the environment via 3D sensor locations and orientations. A single object is presented to the camera and an initial arbitrary image is acquired. A 2D optimization process is developed. It brings the object in the field of view of the camera, normalizes it by centering the data in the image plane, aligns the principal axis with one of the camera's axes (arbitrarily chosen), and finally maximizes its resolution for better feature extraction. The enhanced image at each step is projected along the corresponding viewing direction. The new projection is intersected with previously obtained projections for volume reconstruction. During the global exploration of the scene, the current image as well as previous images are used to maximize the information in terms of shape irregularity as well as contrast variations. The scene on the borders of occlusion (contours) is modeled by an entropy-based objective functional. This functional is optimized to determine the best next view, which is recovered by computing the pose of the camera. A criterion based on the minimization of the difference between consecutive volume updates is set for termination of the explo
