Abstract
The surface structure of a container lock pin is complex,making it difficult to establish a point cloud model with a high surface feature integrity.Therefore,a multi-view and multi-attitude point cloud model reconstruction algorithm based on a turntable was proposed to restore the complete surface features of the locking pin.Considering that sensors at a fixed height are paired with rotating turntables in most scenarios,the collected surface features are usually somewhat missing.Initially,the algorithm uses the parameter calibration results of the turntable to realize the multi-view three-dimensional point cloud stitching,and establishes a fixed attitude point cloud model.Then,through the proposed improved spherical projection algorithm,the positioning of the locking pin on the turntable is selected to establish a point cloud model under another posture.Finally,the point cloud model with multiple attitudes is integrated to improve its surface characteristics.Experimental results show that the proposed algorithm can build a lock-pin point cloud model with high surface feature integrity.关键词
