Three-dimensional reconstruction method based on kinematic calibration of line structured light point set individualization

A three-dimensional reconstruction method based on kinematic calibration of line structured light point set individualization, comprising the following steps:

• rigidly assembling an area-array camera and a line structured light emitter, and mounting the assembly on a five-axis motion platform to obtain a measuring device,
• wherein, five axes of the five-axis motion platform comprise an X axis, a Y axis, a Z axis, a rotation axis rotating around an X-axis direction and a rotation axis rotating around a Y-axis direction;
• calibrating structural parameters of the motion platform of the measuring device by using a reference radius of a standard sphere and line structured light scanned data to obtain a calibrated measuring device;
• registering a spatial position relationship of a line structured light point set by taking a calibrated spherical center position of the standard sphere and the reference radius of the standard sphere as constraints to obtain a real-time point cloud registration matrix;
• controlling the five-axis motion platform to move and acquiring scanned data of a measured member under different poses;
• and
• completing high-quality three-dimensional model reconstruction of the measured member subjected to multi-pose scanning by using the scanned data and the real-time point cloud registration matrix based on the calibrated measuring device.
