Networking method of multi-view stereo-vision measurement network
Qiao Yujing, Jia Baoming, Jiang Jingang, and Wang Jingyi
Stereo-vision network measurement was the core technology for 3D measurement. In order to ensure the full coverage and reconstruction accuracy of 3D reconstruction, the camera needed to be intensively shot during the measurement process, resulting in slow 3D measurement and large calculation.Therefore, a multi-view ste
