Embodiment 1
[0077] An embodiment of the present invention provides a method for determining a plane in point cloud data, including:
[0078] Divide the point cloud data into multiple sub-datasets according to the coordinates; specifically, the point cloud data can be divided according to the coordinates on the three axes of x, y, and z at the same time, so that the entire point cloud data can be divided into multiple sub-data sets Set, that is to say, divide the space corresponding to the entire point cloud data into multiple subspaces of uniform size, and each subspace corresponds to a subdataset;
[0079] Determine a local plane for each sub-dataset in multiple sub-datasets; specifically, since the subspace corresponding to each sub-dataset is a small part of the space corresponding to the entire point cloud data, it can be approximately considered that the sub-dataset in the sub-dataset There is only one plane, therefore, by plane fitting to the data points in the sub-dataset, a local ...
