Embodiment Construction
[0048] The technical solution of the present invention is described in detail below through specific embodiments:
[0049] A point cloud splicing method based on precision control field and point cloud feature similarity, comprising the following steps:
[0050] 1) The reference measurement system collects the coordinates of each mark point pre-arranged on the surface of the measured object and the station, constructs a precision control field and a global coordinate system, and records the three-dimensional coordinates of each mark point in the global coordinate system as the reference three-dimensional coordinates;
[0051] 2), use the three-dimensional scanning sensor to obtain the point cloud of the measured object in the initial pose, which is recorded as point set A;
[0052] The 3D scanning sensor contains at least 3 marker points in the image collected by the initial pose;
[0053] Calculate the initial transformation relationship between the three-dimensional scannin...
