作者： KORZUN, A KUKAREKO, E PASHKEVICH, A Minsk Radioengineering Institute (Belarus)

ISBN: (纸本)0819413216

The paper is devoted to robot accuracy improvement via calibration and contains correspondent algorithms, hard- and software description. The experimental part of this work has been performed with PUMA robots. The hardware includes a sensor unit mounted on the robot arm consisting of a CCD camera and four optical proximity sensors. The proposed algorithm is based on an integral estimate of straight path distortions and minimization of them by altering the parameters of the robot model.

A robotic work cell for stripping paint from both large and small aircraft is currently under development at Pratt & Whitney - Waterjet Systems (formerly USBI Co., Advanced Programs). The primary objectives for this system are to reduce the time required to strip an aircraft, improve the quality and consistency of the stripping operation, and reduce the need for environmentally objectionable stripping processes such as chemical methods. One of the keys to the overall success of this automated paint stripping system is the integration of a sensor that will provide for adaptive process control. This sensor must be able to indicate when a layer of paint has been completely stripped from the aircraft, and measure the approximate size of any remaining unstripped patches. The sensor should also be able to indicate when surface roughening is occurring on the material beneath the paint.

Textural filters that are designed in the texture spectrum domain are used by slightly changing rules in the calculation of the texture unit number by ordering the elements of the texture unit with respect to the positions of maximum and minimum gray level values as their initial positions in the 3 X 3 subimage. Following that, maximum and minimum values, in addition to the average value of standardized nine elements, are also considered in the transformation processes. Condition morphological filter is applied on the texture filtered image of 200 X 300 pixel data. The results are showing promising potential for geological feature recognition.

New Gabor transform (GT) filters to detect candidate object locations independent of the object class, object distortions, and for low contrast objects in clutter are described. A new neural network (NN) technique is described to automate selection of GT parameters and to combine multiple Gabor functions (GFs) into once composite macro GF detection filter. Fusion of real and imaginary GT filter outputs is used to reduce false alarms, (P_FA), while maintaining high detection rates (P_D). Test results on the TRIM-2 database are provided.

In this paper, a high-resolution algorithm for detecting the orientation and position of an IC, and an algorithm for compensating the position and skew angle of a PCB, are proposed. The proposed algorithm for the first topic consists of two parts. Its first part is a preprocessing step, in which corner points of an IC are detected and are separated into two groups. Then the coarse angle of the principal axis is obtained by line fitting. The second part is a main processing step, in which the Hough transform over the limited range of angles is applied to the corner points to detect precisely the orientation of an IC or a surface mounting device (SMD). The position of an IC or SMD is determined by using its four corner points. The proposed algorithm for the second topic is the one which detects a rotation angle and translation parameters of a PCB using a template matching method. The PCB is compensated by the detected parameters. The computer simulation shows that the parameters obtained by proposed algorithms are more accurate than those by the several conventional methods considered. The proposed algorithms can be applied to the fast and accurate automatic inspection systems.

Autonomous and guide assisted vehicles make a heavy use of computer vision techniques to perceive the environment where they move. In this context, the European PROMETHEUS program is carrying on activities in order to develop autonomous vehicle monitoring that assists people to achieve safer driving. Car detection is one of the topics that are faced by the program. Our contribution proposes the development of this task in two stages: the localization of areas of interest and the formulation of object hypotheses. In particular, the present paper proposes a new approach that builds structural descriptions of objects from edge segmentations by using geometrical organization. This approach has been applied to the detection of cars in traffic scenes. We have analyzed images taken from a moving vehicle in order to formulate obstacle hypotheses: preliminary results confirm the efficiency of the method.

In this paper, a number of spatial/spatial-frequency image representations are reviewed. Wavelets have recently generated much interest, both in applied areas as well as in more theoretical ones. Wavelet tranlorm relative to some basic wavelets, provides aflexible time-frequency window which automatically narrows when observing high frequency phenomena and widens when studying lowfrequency environments. As a result, it is suitablefor visual information representation. Applications in computer vision such as image compression and image enhancement are examined. © 1993 SPIE.

Advanced courses in the areas of Machine Perception and Machine Intelligence are not easy to prepare or conduct due to the dynamic research nature of the field. In engineering, our interest is in the construction of intelligent machines in the form of robotic devices or through computer simulation models. Studies in this area are further complicated by the broad range of disciplines that must be accessed in order to provide adequate coverage. This discussion focuses on a set of computer simulation projects that have been assigned at various times during offerings of an advanced graduate level course entitled Machine Perception. The format of the projects are presented with discussion of student results. The projects were novel in that they require advanced techniques of machine vision and are open-ended in that there are no specific solutions. The problems represent the mainstream of machine perception research without requiring more effort than is possible in a one semester course. Students responded with algorithms developed in a variety of computer languages and on various machines.

We discuss recent results from our ongoing research concerning the application of artificial evolution techniques (i.e., an extended form of genetic algorithm) to the problem of developing `neural' network controllers for visually guided robots. The robot is a small autonomous vehicle with extremely low-resolution vision, employing visual sensors which could readily be constructed from discrete analog components. In addition to visual sensing, the robot is equipped with a small number of mechanical tactile sensors. Activity from the sensors is fed to a recurrent dynamical artificial `neural' network, which acts as the robot controller, providing signals to motors governing the robot's motion. Prior to presentation of new results, this paper summarizes our rationale and past work, which has demonstrated that visually guided control networks can arise without any explicit specification that visual processing should be employed: the evolutionary process opportunistically makes use of visual information if it is available.

This paper describes some of the first analytic work performed on data collected by an autonomous 3D machine vision system. The system, which is described in detail elsewhere and briefly described here, uses fast, dedicated hardware to generate a visible surface mapping directly into a memory array that can be accessed from a host computer. The techniques described here have shown some success in the separation of individual surfaces in multi- surface objects and a range of results are presented.
