Embodiment Construction
[0028] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0029] figure 1 The flow chart of the denoising method for 3D point cloud data provided by the embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0030] Step S110, extracting the depth data of the three-dimensional point cloud data, and establishing a two-dimensional point cloud matrix, and the elements in the two-dimensional point cloud matrix are the depth data.
[0031] Specifically, the acquisition of 3D point cloud data is the 3D coordinates of the 3D image captured by the time-of-flight sensor. The 3D coordinates are stored in the sensor chip through a pixel array, and the 3D coordinates used are values generated based on the sensor coordinate system. It includes position information of the measured object on a projection plane and depth information of the measured object,...
