Abstract

The embodiment of the present disclosure discloses a method for estimating image depth. The method includes: obtaining the reference frame corresponding to the current frame and the inverse depth space range of the current frame; performing pyramid downsampling processing on the current frame and the reference frame respectively to obtain the corresponding The k-layer current image and the k-layer reference image corresponding to the reference frame; k is a natural number greater than or equal to 2; based on the k-layer reference image and the inverse depth space range, the k-layer current image is subjected to inverse depth estimation iterative processing to obtain the current frame The inverse depth estimation result of . By implementing the above solution, the depth estimation result of the image can be obtained in real time, and the accuracy of the depth estimation result is high.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to an image depth estimation method and device, electronic equipment, and a storage medium. Background technique [0002] Depth estimation of images is an important problem in the field of computer vision. When the depth information of the image cannot be obtained directly, only the depth estimation method can complete the 3D reconstruction of the scene, and then serve applications such as augmented reality and games. [0003] At present, depth estimation methods based on computer vision can be divided into two categories: active vision methods and passive vision methods. Among them, the active vision method is to point the measured object to emit a controllable beam, and then take the image formed by the beam on the surface of the object, and calculate the distance of the measured object through the geometric relationship. The passive vision method includes st...
