Abstract

The invention provides a scanning target fixing device. The device comprises a target fixing base, a support rod set and support terminals. The support rod set comprises at least three support rods, wherein one end of each support rod is hinged to the target fixing base, and the other end of each support rod is provided with one support terminal; the target fixing base comprises a magnetic attraction base and a target fixing clamp; the target fixing clamp is installed on the magnetic attraction base and used for attracting, clamping and fixing a scanning target. The bottoms of the support terminals are provided with a magnetic attraction chassis capable of being attracted and fixed to the magnetic installation face, and the magnetic attraction chassis is used for erecting and installing the scanning target fixing device on a horizontal plane or a non-horizontal plane. According to the invention, the scanning target is fixed by the target fixing clamp and the magnetic attraction base, so the scanning target cannot fall off from the fixing device when being erected on a non-horizontal plane; by combining the support rods and the magnetic type support terminals, the problem that the three-dimensional laser scanning target is large in layout limitation is solved.

Description

technical field [0001] The invention relates to the technical field of laser scanning, in particular to a scanning target fixing device. Background technique [0002] The rapid development of 3D laser scanning technology has replaced many traditional single-point coordinate measurement methods due to its high-efficiency, non-contact and high-precision acquisition of multivariate data such as point cloud coordinates, color and reflectivity on the surface of the scanned object. The multi-station original point cloud data obtained by 3D laser scanning needs common features as stitching primitives during stitching and orientation, and the scanning target is the most commonly used common feature. Common scanning targets include spherical targets and black-and-white checkerboard-shaped planar targets, among which spherical targets are mostly plastic balls with good reflection, and black-and-white checkerboard-shaped planar targets are mostly metal sheets coated with various high-c...
