Abstract
PURPOSE: To obtain continous contour lines in real time by operating an image pickup device and a pattern generator synchronously, leading the video signal from the image pickup device and the detection grating image signal from the pattern generator to an exclusive OR circuit and making logic operation.
CONSTITUTION: Light is emitted from the 1st point, and a grating image is projected on the body to be measured. From the 2nd point, said grating image is picked up with an image pickup device 8 and the video signal having logic value is outputted. In addition, it is synchronized by a clock generator 10 and the detection grating image signal which is relatively static with respect to said video signal and has logic value is outputted from the pattern generator 9. The output of the image pickup device 8 and the output from the pattern generator 9 are led to an exclusive OR circuit 19 where they are subjected to logic operation, whereby the video signal indicating the contour area coupling the areas P and Q is written into a picture memory 18. This is read out and desired processing may be performed in an image recognition circuit 20.
