[0026] When using a 3D laser scanner to verify the stripping test method of an open-pit mine, a backsight point needs to be set up behind the measuring point for orientation. At first, most people used a centering rod to manually support the viewpoint. The centering rod support was not stable enough, and there was a centering error, which affected the accuracy of data collection. At the same time, manually setting up the backsight point requires a lot of manpower, material resources and working time, which affects the efficiency of measurement. During data collection, the backsight point and the measuring station need to maintain line of sight. The backsight point sometimes needs to be set in a more dangerous place, which poses a safety risk.

[0027] In response to the above-mentioned problems, in some embodiments of the present application, a three-dimensional laser scanner rear-view directional pile is provided, in which a fixed directional pile is directly set at a clear field of vision, thereby effectively avoiding the centering error caused by insufficient verticality of the centering rod, improving the accuracy of data collection, and being easy to use. There is no need for another staff to set up the centering rod again every time, thereby reducing labor costs and helping to improve the efficiency of data collection.

The inner diameter of the sleeve 2 is larger than the diameter of the centering rod 3, and the sleeve 2 is provided with an adjusting bolt 5 for adjusting the verticality of the centering rod 3. When in use, the verticality of the centering rod 3 can be adjusted by adjusting the bolt 5, thereby ensuring the accuracy of the collected data.

[0031] Optionally, in some embodiments, Figure 2 As shown, one end of the adjusting bolt 5 is inserted into the sleeve 2 and abuts against the centering rod 3, and is screwed with the sleeve 2; three adjusting bolts 5 are provided, which are evenly spaced around the circumference of the sleeve 2 and are arranged close to the top of the sleeve 2. When adjusting, the tilt direction of the centering rod 3 is determined according to the level 4, and then the adjusting bolt 5 on the corresponding side is rotated, so that the centering rod 3 can be driven to move to the other side, so as to achieve the purpose of adjusting the verticality of the centering rod 3, and the adjustment is convenient.

[0032] Optionally, in some embodiments, two groups of adjusting bolts 5 are provided, one group is provided near the top end of the sleeve 2, and is used to adjust the position of the centering rod 3 at the top end of the sleeve 2, and the other group is provided near the lower end of the centering rod 3, and is used to adjust the position of the bottom end of the centering rod 3 in the sleeve 2, thereby achieving the purpose of adjusting the verticality of the centering rod 3 and ensuring the accuracy of the measurement data.
