摘要:
This invention provides a three-dimensional measurement system that improves the efficiency of and enables the automation of non-contact three-dimensional measurement over a wide range using a coded target. A measuring object 1 is photographed in stereo such that the resulting images include four coded marks CT each having a position detection pattern P1 and a code pattern P3. A series of images are photographed in stereo such that adjacent images share two coded marks CT. The position detection pattern P1 and the code pattern P3 are extracted from a pair of photographed images. A point corresponding to a reference point is searched for using the identification codes of the coded marks CT. A stereo matching area is determined. All the processes including photographing, extraction, orientation and three-dimensional measurement can be fully automated.
