Abstract

The invention discloses a double prism group device for opposite observation, comprising a handle (1) and a double prism group; the handle (1) is used to fix the double prism group on a total station, and Fix the double prism group by the handle (1), to ensure that the center of the double prism is on a straight line with the measurement center of the total station; the double prism group includes a double prism frame (2), a first prism (3 ) and the second prism (4), the double prism frame (2) is connected with the handle (1) through the adapter part (5); the first prism 3 and the second prism 4 are two facing opposite And angle adjustable single prism. By adopting the present invention, by controlling the total station to rotate and measure the double prism targets with opposite directions up and down and adjustable angles, the angle measurement error of laser measurement is corrected, and the measurement precision and accuracy of the double prism group device are effectively improved.

Description

technical field [0001] The invention relates to laser surveying and mapping measurement and photoelectric tracking technology, in particular to a double prism group device for facing observation. Background technique [0002] Ordinary single prism has the characteristics of simple operation and flexibility, and was widely used in the field of surveying and mapping in the past. However, due to the limitation of system error, the application of single prism device for surveying and mapping cannot guarantee the high precision and accuracy of point measurement. Therefore, double prism group is often used for measurement to improve. [0003] The existing method of using a double prism group device for accurate measurement is to place the first prism, the second prism and the measured point on a straight line, the linear distance between the second prism and the measured point is known, and the total station is used to The instrument measures the three-dimensional coordinates of ...
