Abstract: A point cloud encoding method is provided. The method includes the following. A residual value of attribute information of a current point in a point cloud is determined according to a prediction value of the attribute information of the current point. An index of the current point is determined. Lossless encoding is performed on the residual value of the attribute information of the current point, when the index of the current point belongs to an index range of a first point. A quantized residual value of the attribute information of the current point is obtained by quantizing the residual value of the attribute information of the current point based on a quantization weight of the current point and a quantization step size of the current point, when the index of the current point is beyond the index range of the first point, and the quantized residual value is encoded.

Abstract: The present disclosure provides a method for increasing luminescence uniformity and reducing afterglow of a Ce-doped gadolinium-aluminum-gallium garnet structure scintillation crystal, a crystal material and a detector.
