Image rendering method and device and electronic equipment

The invention discloses an image rendering method and device and electronic equipment, and belongs to the technical field of computers. The method comprises the steps that an object is scanned through scanning equipment, multiple pieces of original point cloud data are obtained, and any piece of original point cloud data is used for describing a data collection point on the object; on the basis of the multiple pieces of original point cloud data, at least one piece of boundary line data is determined, and any one piece of boundary line data is used for describing a contour boundary on the object; and determining an object image based on the multiple pieces of original point cloud data and the at least one piece of boundary line data, and rendering the object image. Since the object image is determined based on the plurality of original point cloud data obtained by scanning the object, the object image can accurately reflect the object, and the accuracy is high.
