description The disclosure provides a coding method and an electronic device for point cloud compression. A 2D image and an occupancy map of point cloud are obtained. Am occupancy status of point cloud data of each pixel sample in the 2D image is determined according to the occupancy map. A weight parameter of each pixel sample in a coding block of the 2D image is determined according to the occupancy statuses of point cloud data of a plurality of pixel samples. A plurality of rate-distortion costs respectively corresponding to a plurality of encoding operation options are calculated according to the weight parameters of each pixel sample in the encoding block. One of the plurality of encoding operation options is determined to be applied to perform an encoding operation on the encoding block according to a minimum rate-distortion cost among the plurality of rate-distortion costs.
