Most of these activities are based on two different types of radar long- and short range different frequencies and on various types of laser range finders LRF . Multiple planes in LRF with both scanning and multiple beam designs are under consideration. Typical angular resolutions for modern LRF designs go down to about 2 mrad . This means that at 50 m distance the resolution is about 10 cm a reasonable value for slow speeds driven. If interference problems with active sensing can be excluded these modern LRF sensors just being developed and tested may be sufficient to solve the problem of obstacle recognition. However human vision and multifocal active technical vision can easily exploit ten times this resolution with systems available today. It will be interesting to observe which type of technical vision system will win the race for industrial implementation in the long run. In the past and still now computing power and knowledge bases needed for reliable visual perception of complex scenes have been marginal. Outlook on Object Recognition With several orders of magnitude in computing power per processor becoming available in the next one or two decades las in the past according to Moore s law the prospects are bright for high-resolution vision as developed by vertebrates. Multifocal eyes and special glasses under favorable atmospheric conditions will allow passive viewing ranges up to several kilometers. High optical resolution in connection with passive perception of colors and textures will allow understanding of complex scenes much more easily than with devices relying on reflected electromagnetic radiation sent out and reflected at far distances. Generations of researchers and students will compile and structure the knowledge base needed for passive vision based on spatiotemporal models of motion processes in the world. Probably other physical properties of light like direction of .
