Abstract

The embodiment of the invention discloses a depth image generation method and device, electronic equipment and a storage medium. The depth image generation method comprises: obtaining a color image and a depth image, wherein a scene indicated by the color image is matched with a scene indicated by the depth image; and in response to determining that the target area exists in the depth image, re-determining the depth value of the pixel point in the target area based on the color image to obtain a new depth value, the accuracy of the depth value of the pixel point in the target area being less than or equal to a preset accuracy threshold. According to the embodiment of the invention, the depth value of the pixel point in the image area with low accuracy in the depth image corresponding to the color image is re-determined based on the color image, so that the new depth image is generated, and the accuracy of the depth value of the pixel point in the depth image is improved.

Description

technical field [0001] The present disclosure relates to image processing technology, in particular to a depth image generation method, device, electronic equipment and storage medium. Background technique [0002] At present, it has become a development trend of more and more electronic devices to be equipped with a lidar system. For example, at this stage, some mobile terminals (such as mobile phones) of users already have this function. [0003] However, not all the depth values ​​of the pixels in the depth image obtained by electronic devices equipped with lidar have high accuracy. In practice, limited by the power consumption of electronic devices and other reasons, the original depth images obtained by the lidar of some electronic devices are very sparse. Some electronic devices can use software to complement the acquired original sparse depth image, so as to obtain a denser depth image. [0004] However, the accuracy of the depth values ​​of the pixels of the depth...
