Abstract

In this study a color 3-D range finder operating at the video rate has been developed for the purposes of industrial and welfare application. The range finder with simplified circuits discriminated eight colors through classifying the R, G, B signals from binocular cameras into high and low brightness levels. The corresponding color boundaries were determined by comparing binarized brightness levels, thereby enabling the derivation of an accurate parallax signal. This finder was applied to three-dimensional measurements of distances and dimensions. The influence of color combinations on the distance acquisition rate was examined. The results showed that the finder is useful as a practical device.
