Abstract :
A new type of dot-distribution coded targets for digital industrial photogrammetry was presented in the paper. The coded target was composed of 5 template points and 3 code points. Different character strings were used as coder for each coded target, and the max capacity was 496. Affine transformation and cross ratio were adopted to decode the targets automatically and rapidly. Experiments proved that this type of dot-distribution coded targets fulfill the requirements of automatic digital industrial photogrammetry.
