640/spl times/480 Real-time range finder using high-speed readout scheme and column-parallel position detector
In this paper, we present the first real-time range finder with the capability of VGA (640/spl times/480) resolution based on a light-section method. We propose an adaptive thresholding circuit and column-parallel time-domain approximate ADCs to realize high-speed readout for real-time range finding. Sub-pixel position calculation based on intensity profile by the readout scheme achieves high-accuracy range finding. A column-parallel position detector suppresses redundant data transmission for a real-time measurement system.
