【摘要】：为了实现室内大范围环境激光测距,采用三角测距原理设计了一套高速激光测距系统。该系统采用高分辨率线性CCD传感器采集环境信息并输出二值化信号,由32位单片机对二值化信号进行处理,利用分段拟合法得到的距离解算算法对二值化信号进行解算,从而得到激光光斑与测距模块镜头中心的距离;最后进行了实验验证。结果表明,测距仪具有714Hz的测量频率,最大测量距离为6311mm,最小测量距离为48mm,平均误差为2.8mm,最大测量误差为11mm。该测距系统可满足室内大范围环境测量的要求。
[Abstract]:A high speed laser ranging system is designed based on triangle ranging principle in order to realize laser ranging in large range indoor environment. The system uses high resolution linear CCD sensor to collect environmental information and output binary signal. The binary signal is processed by 32-bit singlechip, and the binary signal is calculated by the distance solution method obtained by piecewise fitting method. The distance between the laser spot and the lens center of the ranging module is obtained. The results show that the range finder has the measuring frequency of 714Hz, the maximum measuring distance is 6311mm, the minimum measuring distance is 48mm, the average error is 2.8mm, and the maximum measuring error is 11mm. The range measuring system can meet the requirement of indoor wide range environmental measurement.
