红外测距仪和其它测绘仪器一样,在使用过程中,均应对仪器的性能和精度进行定期检测,以确保作业精度。一台新出厂的仪器,工厂虽提供了标称精度,由于厂家制造工艺的差异,产品有优有劣,精度有高有低,以及仪器经过长途运输,仪器的各项指标都会发生一些变化,因此,更应该对仪器进行全面的测试和鉴定。红外测距仪检测项目有多项,本文仅介绍检测仪器内、外符合精度的方法。 (一)仪器内符合精度的测定所谓内符合精度,是指在外界因素基本不变的情况下,仪器对于一固定边的多次测 Infrared range finder and other mapping instruments, in the course of use, should be on the instrument performance and accuracy of regular testing to ensure the accuracy of operations. A new factory equipment, although the factory provides a nominal accuracy, due to differences in manufacturers manufacturing process, the product is superior, the accuracy is high and low, and the instrument after long-distance transport, the instrument of the indicators will be some changes, so , But should conduct a comprehensive test and identification of the instrument. Infrared rangefinder testing a number of items, this article describes only the detection of instruments, outside the method of accuracy. (A) Determination of the instrument in line with the accuracy of the so-called within the line with the accuracy, refers to the external factors in the same basic circumstances, the instrument for a fixed edge of the test
