The Implementation of Positioning Measurement Based on Laser Range Finder and 2-D Pan/tilt

摘要

Taking the application requirements of target's positioning measurement by using mobile robot and robot's self-positioning as background in engineering application. This paper brought out a method of rotation translation matrix's calibration by using four feature points. This paper discussed the way to improve measurement accuracy. The method had achieved target's positioning measurement and measurement unit's self-positioning by positioning measurement unit in the environment that people can't reach. The unit is formed by laser range finder, 2-D pan/tilt and detection camera. The test analysis showed that this positioning measurement method is stable and accurate, and guarantees a certain degree of real-time and operability. It has some promotion significance in engineering.
