摘要
RIEGL LMS-Q140i-80激光扫描仪是863课题“近景目标三维测量技术”中关键传感器之一,其精度直接影响课题所能达到的精度指标。为衡量扫描仪实际精度与其标称精度的一致性,设计扫描仪在静止情况下进行扫描实验。实验结果表明:扫描仪的实际精度与其标称精度相一致,满足课题对传感器的精度要求。
RIEGL LMS-Q140i-80 laser scanner is the main sensor of 863 program 'Close Range 3D Measurement Technology',and its precision affect the precision of the program directly.In order to evaluate the consistency of the actual precision and given precision of laser scanner,a lot of tests have been done when scanner is still.The results indicate that the actual precision and given precision of laser scanner is consistent,and can meet the requirement of precision of laser scanner in 863 program.
