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

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.
