Abstract

The invention discloses a high-quality depth estimation method based on depth prediction and an enhanced sub-network, and belongs to the field of image processing and computer vision. The method comprises performing depth prediction on a color map by constructing a depth prediction sub-network, and using a depth enhanced sub-network to recover the resolution of a low-resolution image obtained by the depth prediction sub-network, thereby obtaining a high-resolution depth prediction map. The method is simple and easy to implement. The system is easy to construct, and can obtain a corresponding high-quality depth map from a single color map end to end by using a convolutional neural network. The information lost by the downsampling of the depth prediction sub-network is restored by the high-frequency information of the color image, and a high-quality and high-resolution depth map is finally obtained. The spatial pooling pyramid structure effectively solves the problem of predictive accuracy caused by different object sizes.

Description

technical field [0001] The invention belongs to the field of image processing computer vision, and relates to the use of a depth prediction sub-network to predict the depth of a color image, and the use of a depth enhancement sub-network to restore the resolution of a low-resolution depth map obtained by the depth prediction sub-network, thereby obtaining a high resolution The depth prediction map of , specifically relates to a high-quality depth estimation method based on depth prediction and enhanced subnetworks. Background technique [0002] The depth of field of a real scene, that is, depth information, is a method to measure the third dimension of a scene, and is widely used in various computer vision tasks, such as pose estimation, 3D modeling, etc. Although high-quality texture information can be easily obtained using color cameras, the acquisition of depth information is still a very challenging topic. In the traditional method, the acquisition of depth information ...
