| In order to improve the ranging accuracy of laser range finder, we used the time digital converter chip TDC_GP21 of ACAM, designing a high precision time interval measurement module, using data fitting algorithm to calibrate the ranging system, and the average value of multiple ranging arithmetic is used to improve the accuracy of the system. The measurement results show that the circuit is simple, the precision is high, the cost is lower, and it has the feasibility of mass production. |
