摘要

在本文中，我们提出了基于光剖面法的第一个具有VGA (640/spl倍/480)分辨率的实时测距仪。我们提出了一种自适应阈值电路和列并行时域近似adc来实现实时测距的高速读出。通过读出方案进行基于强度轮廓的亚像素位置计算，实现高精度测距。柱-并联位置检测器抑制了实时测量系统的冗余数据传输。

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.
