Image compression: Ready for prime time?

This paper describes the design, construction, and measured performance of an experimental scanning laser rangefinder. The instrument uses active triangulation and employs an optical bandpass filter to minimize the effects of ambient illumination. Its use of a single photodetecting element, a photomultiplier, is a unique feature among scanning triangulation rangefinders. A novel scanning configuration based on spherical coordinates is employed, resulting in an extremely large field of view. Nearly 75% of the surrounding solid angle is accessible. Reasonably high speed and accuracy are obtained. The typical error in range at a range of 50 in. is.12 in. The typical error in either of the two angular coordinates is.03°. The maximum instantaneous rate of acquisition of range samples is 500 Hz. Much higher speed and accuracy appear achievable with various modifications and improvements. This type of rangefinder appears most useful in automatic surveillance and robot navigation applications, because of its large field of view. 1.

Machine vision in its common definition is a possibility of a machine (by sensing means and computer mathematic processing consecutively) to obtain an information about surrounding environment for further analytical treatment. According to this common definition we can unite in a general

The continuing development of machine vision is initiating a change from human to machine vision for inspection purposes. This paper concentrates on a general analysis graph within a systematic automated visual inspection concept that speeds up the development of such systems by increasing

there have been excursions into the development of ideas in this area since the very beginnings of work on machine vision, much work remains to be done. Progress will depend on careful attention to matching of the capabilities of simple networks to the needs of early vision. Note that this is not at all
