在批林批孔运动的推动下,我厂广大职工在冶金部河北省冶金勘察公司和清华大学等有关单位的协助下,积极移用已有激光产品技术成果,于1974年春试制成功一种新型激光地形测绘仪(图1).一年来,激光地形测绘仪在一些领域的实际应用中,证明性能良好,符合使用要求.在地形勘察测量中,这种仪器可以代替原来采用经纬仪人工立标尺的视距测量法,实现了无人立标测绘.因此,激光地形测绘仪的使用具有减轻劳动强度、提高工作效率、提高测绘质
With the help of Lin-bian Kong campaign, with the help of metallurgical exploration companies of Hebei Metallurgical Department and Tsinghua University and other relevant units, the vast majority of staff and workers of our factory have actively transferred the technological achievements of the existing laser products and succeeded in making a new type of trial in the spring of 1974 Laser topography (Figure 1). Over the past year, laser topographic mapping instrument in some fields of practical application, to prove good performance, in line with the requirements of use.In terrain survey survey, this instrument can replace the original artificial theodolite ruler Line of sight measurement method to achieve unmanned vertical mapping.Therefore, the use of laser topographic mapping instrument has to reduce labor intensity, improve work efficiency and improve the quality of mapping
