The invention discloses a target suitable for a
fast scanning scene and an extraction method of a
target control point. The target is composed of a plane X, a plane Y and a plane Z which are not parallel to one another; and the
target surface of the target is coated with silver white paint. The method includes the following steps that: S1, a
laser scanning
system is adopted to scan the target and carry out coordinate calculation on obtained
point cloud data; S2, target
point cloud data in three-dimensional
point cloud data are identified and intercepted, so that point cloud subspaces can be obtained; S3, plane model
estimation is carried out the point cloud subspaces, denoising is carried out by using the dichotomy, so that basic point cloud can be obtained, and noises are eliminated; S4 iterative denoising
processing is performed on the basic point cloud, and accurate plane parameters can be obtained; and S5, the obtained parameters are adopted to build a nonhomogeneous linear equation set, and the
target control point can be solved. The target and the extraction method of the
target control point are suitable for scenes where carrier platforms move fast. With the method adopted, the coordinates of the target
control point in point cloud can be quickly and accurately determined, and therefore, the accuracy of point
cloud data can be improved. The method has a high application value.
