Embodiment
[0121] The invention discloses a multi-camera dynamic scene 3D reconstruction method based on joint optimization, which can solve the time-space consistent depth restoration and static / dynamic double-layer segmentation at the same time, and does not require accurate static / dynamic segmentation, and the method is robust And no prior knowledge of the background is required. This method allows the participating multi-cameras to move freely and independently, and can handle dynamic scenes captured by only 2~3 cameras. Such as figure 1 As shown, this method mainly includes three steps: First, we use the synchronized video frames spanning M cameras at each time t To initialize the depth map at time t ; 2. Simultaneously carry out deep spatio-temporal consistency optimization and static / dynamic two-layer segmentation, we iteratively perform 2~3 rounds of spatio-temporal consistency optimization, so as to finally achieve high-quality dynamic 3D reconstruction. The implementation ...
