Problems solved by technology
[0003] However, for the scene where depth estimation is to be performed, since some objects in the scene are moving, the relative pose between the field camera and the object is uncertain when imaging each frame of image, which will affect the accuracy of image depth estimation to a certain extent. Influence, so the accuracy of monocular image depth estimation needs to be improved

The invention provides a scene depth estimation method and device for a light field camera, and relates to the technical field of computers, and the method comprises the steps: obtaining a training image; the training image is input into a pre-constructed depth prediction model for training, the depth prediction model comprises a depth prediction unit, a convolution-deconvolution unit, a pose recognition unit and a feature fusion unit, and a corresponding prediction depth map is obtained; and performing joint loss calculation on the obtained predicted depth map and a joint loss function of the corresponding first loss function and the second loss function to obtain a corresponding monocular depth estimation map. According to the embodiment of the invention, the total accuracy of monocular image depth estimation can be remarkably improved.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, to a method and device for scene depth estimation of a light field camera. Background technique [0002] Obtaining 3D depth information from 2D images is an important problem in the field of computer vision and an important part of understanding scene geometry. Different from traditional methods based on multi-view and binocular stereo matching, monocular image depth estimation only uses images from a single viewpoint for depth estimation. [0003] However, for the scene where depth estimation is to be performed, since some objects in the scene are moving, the relative pose of the light field camera and the object is uncertain for each frame of image imaging, which will cause certain problems to the accuracy of image depth estimation. Therefore, the accuracy of monocular image depth estimation needs to be improved. SUMMARY OF THE INVENTION [0004] The purpose o...
