Automatic Target-identification with the Color-coded-targets

The 3 Dimensional Measuring System is a device to obtain the 3 dimensional coordinates of an object, using its numerous photoimages taken from different angles. This method basically requires the exact identification of the same corresponding points of all the obtained photo-images. But the more numerous are the images, the longer and harder it becomes if we depend on the manual work. To solve this problem we have developed colour-coded targets and a special algorithm with software, which automatically identifies the corresponding targets. We made careful experiments and verified its efficiency with the very satisfactory result. * Corresponding author.
