红外光电测距仪是由北京测绘仪器厂、北京大学、铁道部科学研究院、铁道部第二设计院、铁道部第三设计院共同组成的红外光电测距仪研制组研制的一种短程测距仪器。该测距仪制成后曾在铁道部第三设计院三总队担任的某铁路专用线进行科研样机实测试验,做了定测中线3.5公里复测工作和比较线3.5公里初测工作。实测结果闭合精
Infrared photoelectric rangefinder from Beijing Surveying and Mapping Instrument Factory, Peking University, Ministry of Railways Institute of Science and Technology, the Ministry of Railways, the second Design Institute, Ministry of Railways Third Design Institute jointly formed by the infrared photoelectric rangefinder developed a short range test From the instrument. After making the range finder in the Ministry of Railways Third Design Institute Third Corps served as a railway line for scientific research prototype test, the survey of 3.5 km rehearsal centerline survey and comparison line 3.5 km preliminary test work. The measured results closed fine
