Abstract:
A large -scale measurement system based on a portable laser range finder is presented, which acquires the range and angle information by means of laser range finder and incremental photoelectric enceder. Under the control of servo system consisting of motion eontroller、driver and executive motor, the scanning measurement of the work-piece is implemented. Then, the data is processed using least squares fit and inner diameter measurement of steel circular ring was carried out, with the standard deviation of the radius 0. 2 mm. At last, the combined measurement and coordinate registration algorithm is studied.展开更多
