Method and apparatus for processing three-dimensional vision measurement data

An apparatus for processing three-dimensional vision measurement data, comprising:

• a data reading module, configured to acquire three-dimensional point cloud data measured by a three-dimensional machine vision measurement system;
• a viewed space setting module, configured to establish a viewed space based on the three-dimensional point cloud data;
• a coordinate transformation module, configured to establish a new three-dimensional rectangular coordinate system corresponding to the viewed space, and perform coordinate translation transformation on the three-dimensional point cloud data;
• a basic observation plane setting module, configured to determine three basic observation planes corresponding the viewed space and a rectangular coordinate system corresponding to the three basic observation planes;
• a projection function generating module, configured to project the transformed three-dimensional point cloud data onto the three basic observation planes, respectively, to obtain three plane projection functions;
• a depth value function generating module, configured to generate three depth value functions corresponding to the three plane projection functions based on the transformed three-dimensional point cloud data, respectively;
• a two-dimensional image generating module, configured to digitize the three plane projection functions and the three depth value functions, respectively, and transform them into two-dimensional images in a determined format, to obtain three plane projection images and three depth images;
• and
• a compression module, a storage module and a display module, configured to compress, store, and display the three plane projection images and the three depth images, respectively.
