Title:
WORKPIECE THREE-DIMENSIONAL POINT CLOUD DATA SMOOTHING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/010916
Kind Code:
A1
Abstract:
A workpiece three-dimensional point cloud data smoothing method. A Savitzky-Golay algorithm is utilized for workpiece three-dimensional point cloud data smoothing processing. The algorithm employs a method for combined processing of a grayscale image and a point cloud image, reduces the data volume of raw data processing, and increases the amount of time for processing data. A polynomial fitting method is utilized for smoothing point cloud data and retaining the geometric invariance of a point cloud.
