摘要
电子数字式水准仪于90年代初推出以来,对传统的水准测量起到了革新作用.电子数字式水准仪利用了条形码水准标尺得到的光学图像转换成数字电子图像并且进行数字处理,从而减少了对作业人员目估分划的误差,大大提高了测量精度和工作效率.
The electronic digital level was pushed out in 1990; its appearing has reformed leveling method to traditional meaning. Its surveying principle is to transform the optical image getting from bar code of leveling staff into digital electronic image and then processes them further. Its advantage is able to avoid the estimation error of surveyor's eye and to heighten greatly surveying precision and work efficiency.
