Description

Technical Field

[0001] The utility model relates to the technical field of protection brackets, in particular to a protection bracket for fixing a handheld three-dimensional laser scanner. Background Art

[0002] A handheld 3D laser scanner is a high-tech measuring tool that uses laser lines to project onto the surface of an object and capture 3D data by shooting with a camera at a certain deflection angle. The working principle of this technology is that the laser line is affected by the shape and curvature of the object surface, allowing the software to calculate and generate a 3D image. When performing downhole measurements, the current common method is to directly tie it to the handheld 3D laser scanner with a rope, shake the rope to make the handheld 3D laser scanner turn, and complete the downhole measurement. This method makes the handheld 3D laser scanner unstable when performing downhole measurements, and it is easy to bump against the inner wall of the well, causing damage and affecting its use.
