A new type of range sensing method which is based on the principle of triangulation has been developed. A mirror tunnel is placed between an observation lens and an object to be measured;a light beam is projected through the observation lens on to the object;the projected light spot is imaged by the observation lens on the image plane after reflection with the mirror;a position of the light spot on the object can be determined according to the triangulation. The width of an optical system can be reduced to remarkably smaller than the effective base line of the triangulation, and it may be suitable to miniaturize the size of range sensor such as a proximity sensor.

The backtracking search procedures used to solve consistent labeling problems have exponential complexity in the number of units. Even the addition of relaxation operators cannot reduce the complexity for some problems. There are, however, some classes of problems that can be solved by simpler procedures. One such class is the set of consistent labeling problems having the separation property. In this paper, the author defines this class of problems (which arise in remotesensing), gives a divide-and-conquer algorithm for their solution, and discusses the complexity of the algorithm. Present results indicate expected linear behavior.

This paper deals with the detection and precision location of ground targets in the form of synthetic crosses on real terrain data. Location of crosses using Fourier descriptors can be achieved to within 0. 07 pixels. This method is used to monitor the geometric distortion caused by compressing the data with the cosine transform. Results show geometric shifts up to 0. 5 pixels may occur after compression. Mean and median filters are applied to synthetic test data. These filters show a minimal amount of geometric shift in the presence of noise. The mean filter reduces location error to 0. 025 pixels. A new circular two-dimensional median filter is introduced and is shown to instill less geometric distortion than the conventional rectangular median filter.
