Example Embodiment
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] In one embodiment, as figure 1 According to the flow chart of : the invention discloses a three-dimensional fast scanning method of digital speckle human body;
[0025] The method includes the following steps:
[0026] S100, multi-camera global calibration: a calibration board is arranged in the measurement field of view to calibrate the internal parameters and external parameters of cameras in multiple measuring heads;
[0027] S200, rapid acquisition of human body images: use multiple measuring heads to project random speckle patterns to different positions on the human body surface, and use multiple measuring heads to synchronously collect human body images from different angles;
[0028] S300, human body 3D point cloud reconstruction: based on steps S100 and S200, perform stereo matching and 3D coordinate reconstruction o...
