Satellite image processing method and device, electronic equipment and computer storage medium

Abstract

The invention provides a satellite image processing method and device, electronic equipment and a computer storage medium, and the method comprises the steps: obtaining a satellite image; processing the satellite image by utilizing a semantic branch, a pixel feature branch, a height branch and an offset branch of the first building detection model to obtain a first image feature indicating a building area in the satellite image, a second image feature consisting of pixel features of each pixel of the satellite image; a third image feature comprising the height feature of each pixel in the satellite image, and a fourth image feature comprising the offset feature of each pixel; dividing the building area into sub-areas corresponding to the building according to the second image features; anddetermining the height and the offset of the building according to the height characteristics and the offset characteristics of the pixels in the building subareas, thereby determining the bottom area of the building. According to the scheme, the plurality of branches can perform parallel processing on the satellite image, so that the scheme has higher processing efficiency compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a satellite image processing method, device, electronic equipment and computer storage medium. Background technique [0002] At present, the digital map has become a navigation and wayfinding tool commonly used in people's daily life. In order to make it easier for users to identify buildings on the map, existing digital maps often need to show users the corresponding three-dimensional models of the buildings. For this purpose, the top and bottom of each building need to be detected on the corresponding satellite images. [0003] In the prior art, the instance detection model can be used to detect the top of each building in the satellite image, and then the height prediction model and the offset prediction model can be used to predict the height of the building according to the identified top of each building and the offset (the offset refers to the offset of the botto...
