Abstract

The invention discloses a dynamic target reconstruction method and device based on multiple RGBD cameras, the multiple RGBD cameras are installed at positions of different visual angles, and the method comprises the steps: obtaining RGB images and depth images collected by the multiple RGBD cameras; generating a point cloud of a three-dimensional space by using the depth image and a known camera internal reference; performing frame difference processing on the RGB images and corresponding pre-stored background RGB images in sequence to obtain moving target areas of the RGB images at differentviewing angles; denoising processing is performed on the point cloud corresponding to each moving target area; converting the denoised point cloud from a camera coordinate system to a world coordinatesystem; establishing a three-dimensional model according to the point cloud converted into the world coordinate system; mapping the textures of the RGB images collected from different visual angles to the three-dimensional model to obtain a dynamic target three-dimensional texture model, and completing dynamic target reconstruction. According to the method, the three-dimensional model of the dynamic target can be efficiently reconstructed, and the constructed three-dimensional model is rich in content and high in accuracy.

Description

technical field [0001] The present application belongs to the technical field of computer vision, and in particular relates to a dynamic target reconstruction method and device based on multiple RGBD cameras. Background technique [0002] Traditional intelligent monitoring based on two-dimensional images lacks real three-dimensional information, and in applications such as personnel location tracking and behavior recognition, it is easy to lose targets and has poor robustness. And 3D intelligent monitoring, because of its richer information and 3D space information in real scenes, the robustness of its tracking and recognition can be further improved, and the reconstructed model is used to display the effect, and the effect is more realistic. [0003] At present, the application of three-dimensional intelligent monitoring, such as the patent with the authorized publication number CN102932638A, proposes a 3D video monitoring method based on computer modeling. The video image ...
