An Algorithm of Real-time Locating and Performance Analysis in a Photoelectric Theodolite-based Network

Based on the algorithms for 3-D locating of multi-photoelectric-theodo-lite network,an algorithm named OV(Orthogonal Vector) was presented to carry out real-time target positioning and the formula of the locating precision was deduced,and its performance was demonstrated.Through three photoelectric theodolites,the locating accuracies of the three algorithms were simulated and their geometrical dilution of precision was given by using Monte-Carlo method under different conditions,such as different station er...
