Example Embodiment
[0032] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0033] The present invention is realized in this way. The composite three-dimensional surface shape measurement method combining Kinect and the fringe reflection method is characterized in that it is composed of two key parts: Kinect-based three-dimensional point cloud data acquisition and fringe reflection three-dimensional measurement.
[0034] One is based on kinect point cloud data acquisition;
[0035] Point cloud data acquisition mainly includes two parts: depth information acquisition and point cloud data registration. In-depth data is the essence and soul of Kinect. The transformation from a two-dimensional depth image to a three-dimensional point cloud is a transformation between two coordinate systems. At the same time, the depth information acquisition principle of the device and the coordinate system transformation are also inextricably...
