Study On The Laser Theodolite Automate Measurement System Based On Vision-based Target Tracking

The automated and precision measurement of the athletic target in large-scale space is an important direction of development. the measurement range of measurement system can cover the whole moving space of targets and achieve the function of real time tracking measurement. In the mean time, it requires that a large amount of dense points could be measured for key components. However, the conventional method for large-scale measurement cannot achieve high accuracy, automation, and intelligence, so it is necessary to build a new automatic measurement system based on tracking objects.This thesis provides a design strategy for electronic laser theodolite automatic measuring system based on visual tracking theories, builds a plan for the automatic measurement system of electrical laser theodolite based on vision tracking theories,and focuses on the technical problems such as tracking athletic objects, the automatic guiding of theodolite and automatic collimation measurement of label points. The experiment shows that the measurement method mentioned in this has high accuracy and efficiency project for tracking athletic target and measuring situations for space points.
