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

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

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

Color machine vision opens new possibilities for industrial on-line quality control applications. With color machine vision it's possible to detect different colors and shades, make color separation, spectroscopic applications and at the same time do measurements in the same way as with gray scale technology. These can be geometrical measurements such as dimensions, shape, texture etc. By combining these technologies in a color line scan camera, it brings the machine vision to new dimensions of realizing new applications and new areas in the machine vision business. Quality and process control requirements in the industry get more demanding every day. Color machine vision can be the solution for many simple tasks that haven't been realized with gray scale technology. The lack of detecting or measuring colors has been one reason why machine vision has not been used in quality control as much as it could have been. Color machine vision has shown a growing enthusiasm in the industrial machine vision applications. Potential areas of the industry include food, wood, mining and minerals, printing, paper, glass, plastic, recycling etc. Tasks are from simple measuring to total process and quality control. The color machine vision is not only for measuring colors. It can also be for contrast enhancement, object detection, background removing, structure detection and measuring. Color or spectral separation can be used in many different ways for working out machine vision application than before. It's only a question of how to use the benefits of having two or more data per measured pixel, instead of having only one as in case with traditional gray scale technology. There are plenty of potential applications already today that can be realized with color vision and it's going to give more performance to many traditional gray scale applications in the near future. But the most important feature is that color machine vision offers a new way of working out applications, where mach

The measurement of the characteristic parameters for a moving object with deformation is often an important problem. Here, an approach to analyze the shape change of a ball, when it is kicked in soccer, is proposed by using a simple shape deformation model to evaluate the shape change from the image sequence. Moreover, to determine the parameters of the model which apply to actual ball deformation, the detection of ball is necessary, and the pattern spectrum based on morphological operators is considered. Here, we assume that the deformation surface of the ball is a circular arc, when it is kicked by foot, and the arc is always convex when it is observed from the kicking side. To obtain the parameters of the arc, the preprocessing of the ball image such as local binarization, the region filling and noisy smoothing with morphological operators, is performed from actual image sequence. In order to detect the ball, the pattern spectrum with morphological operators is measured, and then circumscribed circle of the ball is extracted. So, the center and radius of the ball from circumscribed circle and the arc of the deformation surface of the model are obtained. Finally, the characteristic parameters of a moving ball such as the deformation are measured by using the shape deformation model. To demonstrate the effect of this method, we show an application to extract the deformation of the ball in football for the actual sports skill training.

Presently there is still a remarkable gap between the requirements and the capabilities of 3D- vision in the field of industrial automation, especially in manufacture integrated 100%-quality control. For these and a lot of other applications like security and traffic control a new extremely fast, precise and flexible 3D-camera concept is presented in this paper. In order to obtain the geometrical 3D information, the whole 3D object or 3D scene is illuminated simultaneously by means of rf-modulated light. This is realized by using optical modulators such as Pockels cells or FTR optical components (FTR: Frustrated Total Reflection). The back scattered light represents the depth information within the local delay of the phase front of the rf-modulated light intensity. If the reflected wave front is mixed again within the whole receiving aperture using the same optical 2D-modulation components and the same rf- frequency, an rf-interference pattern is produced. A CCD camera may be applied to sample these rf-modulation interferograms. In order to reconstruct the 3D-image a minimum of three independent interferograms have to be evaluated. They may be produced either by applying three different rf-phases or three different rf-frequencies. This procedure will be able to deliver up to some tens of high resolution 3D images per second with some hundred thousand voxels (volume elements). Such a remarkable progress can be achieved by means of three key important steps: Firstly by separating the opto-electronic receiver device from real-time requirements by using homodyne mixing of CW-modulated light. Secondly by applying the rf- modulation signal as an optical reference signal to the receiving optical mixer. And thirdly by using a throughout 2D layout of the transmitted illumination, further, of the optical mixer in the receiving aperture, and of the optoelectronic sensing element, e.g., a CCD-chip.

We overview our recent progress in lander-based robotics for Mars planetary science. Utilizing a 1:1 scale laboratory replica of the NASA Mar Surveyor '98 mission, JPL engineers and Mars science colleagues have demonstrated approaches to lander science functions such as robotic sample acquisition and deposition, end-effector based microscopic viewing, hand-carried science instrument data collection, and science instrument emplacement by a robot. Some of the significant technical advances underlying this simulated Mars flight capability include JPL's innovation of a new lightweight, mechanically stiff, gas deployed telescopic two meter robot arm, and cooperative engineering work with Michigan Tech colleagues on automated visual positioning control of robotic sampling. University of Arizona and JPL have further developed complementary advances in lander-based imaging spectroscopy and its robotic enablement. We outline this work, summarizing its key technical features, and illustrating experimental progress with photographs and an accompanying conference videotape.

ISO 9283 and RIA R15.05 define industrial robot parameters which are applied to compare the efficiency of different robots. Hitherto, however, no suitable measurement systems have been available. ICAROS is a system which combines photogrammetrical procedures with an inertial navigation system. For the first time, this combination allows the high-precision static and dynamic measurement of the position as well as of the orientation of the robot end effector. Thus, not only the measuring data for the determination of all industrial robot parameters can be acquired. By integration of a new over-all-calibration procedure, ICAROS also allows the reduction of the absolute robot pose errors to the range of its repeatability. The integration of both system components as well as measurement and calibration results are presented in this paper, using a six-axes robot as example. A further approach also presented here takes into consideration not only the individual robot errors but also the tolerances of workpieces. This allows the adjustment of off-line programs of robots based on inexact or idealized CAD data in any pose. Thus the robot position which is defined relative to the workpiece to be processed, is achieved as required. This includes the possibility to transfer teached robot programs to other devices without additional expenditure. The adjustment is based on the measurement of the robot position using two miniaturized CCD cameras mounted near the end-effector which are carried along by the robot during the correction phase. In the area viewed by both cameras, the robot position is determined in relation to prominent geometry elements, e.g. lines or holes. The scheduled data to be compared therewith can either be calculated in modern off-line programming systems during robot programming, or they can be determined at the so-called master robot if a transfer of the robot program is desired.

This paper demonstrates the importance of active behavior in machine vision systems. It proposes using activity of the observer for object finding and recognition. The presented robotic system is based on active and qualitative vision approaches which are supplemented by a hierarchical, multiresolution image representation and a parallel implementation of the active vision algorithms. The system uses a hierarchical search strategy to locate and then identify objects in a three-dimensional space. The paper describes the recognition algorithm and its parallel implementation. The preliminary results show near real-time performance.

This paper describes preliminary work on a non-intrusive gaze-driven interface for man-machine interaction based on vision techniques. The current computer screen location pointed at by the user is evaluated using a linear model of image-to-screen mapping, which can be easily auto-calibrated at run-time on the basis of the current relative position of camera and user and camera settings. A simple active deformable model of the eye is defined, which is used both to track user's movements and estimate the current position of the user's pupil in the image in a decoupled fashion. Experiments show that the proposed approach is fast and accurate enough for the design of low-cost man-machine interfaces, with applications ranging from the assistance to the disabled people to multimedia systems.

IEEE International Workshop on intelligent robots and Systems (IROS)

作者： E. Marchand F. Chaumette E. Rutten IRISA-INRIA Rennes Université de Rennes Rennes France

In this paper, we apply the synchronous approach to real time active visual reconstruction. It illustrates the adequateness of SIGNAL, a synchronous data flow programming language, for the specification of a system dealing with various domains such as robot control, computer vision and the programming of hierarchical parallel automata. More precisely, our application consists in the 3D structure estimation of a set of geometrical primitives using a camera mounted on the end effector of a six dof robot. At the level of camera motion control, the visual servoing approach is specified and implemented in SIGNAL as a function from sensor inputs to control outputs. The 3D reconstruction method is based on the "structure from controlled motion" approach. Its specification is made in parallel to visual servoing. We also present a perception strategy for connecting up several estimations, using time intervals and hierarchical structures for task preemption in SIGNAL. The integration of these techniques is validated experimentally by their implementation on a robotic cell.

computer Architectures for Machine Perception (CAMP)

作者： M. Bolduc G. Sela M.D. Levine Center for Intelligent Machines McGill University Montreal QUE Canada

This paper discusses two components of a Robot Eye intended as an active vision system to be mounted on a mobile robot. The first component is a foveated vision sensor which is based on an overlapping receptive field model for data reduction. We present the adapted scan-line algorithm used to compute so-called retinal images and a description of the implementation of the system on a network of DSP's. The second component computes salient points in the foveated image and is motivated by the biological processes which guide primate gaze fixation. The model of attention and its real-time implementation are described. Experimental results obtained with these algorithms are also presented.
