Tree modeling method and tree modeling device based on single image and equipment

The invention discloses a tree modeling method and tree modeling device based on a single image and equipment. The tree modeling method comprises the following steps: acquiring a tree edge graph and a visible branch graph of a single tree image to be reconstructed; inputting the tree edge map and the visible branch map into a pre-trained conditional generative adversarial network to obtain a contour depth map and a branch depth map of the tree; obtaining contour point cloud data according to the contour depth map, and constructing a branch three-dimensional skeleton according to the branch depth map; and by taking the contour point cloud data and the branch three-dimensional skeleton as constraint conditions, generating a three-dimensional tree model of the to-be-reconstructed single tree image according to a predetermined self-organizing process type modeling method. A good modeling effect can be achieved for trees with irregular contours, depth data of the tree contours can be accurately obtained through th
