Abstract

The embodiment of the invention provides an image processing method and device based on perspective projection and electronic equipment. The method comprises the following steps: acquiring camera parameters of a target camera and a main view image shot by the target camera; coding the main view image through a main view image coding network to obtain N first main view spatial features; processing the N first main view spatial features through a first perspective projection module to obtain first aerial view spatial features, and processing target main view spatial features in the N first main view spatial features through a second perspective projection module to obtain second aerial view spatial features; performing feature fusion processing on the first aerial view spatial feature and the second aerial view spatial feature to obtain a third aerial view spatial feature; and carrying out decoding processing on the third aerial view space feature through an aerial view image decoding network to obtain an object segmentation image of the aerial view space. According to the scheme, the semantic segmentation precision of the aerial view is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to an image processing method, device and electronic device based on perspective projection. Background technique [0002] At present, the existing perspective projection (FV2BEV, Frontal View to Bird's-Eye View) algorithm for autonomous driving based on the camera model has a very fatal flaw: the camera model strongly relies on the assumption of a flat ground plane, while the The flat ground assumption is often unsatisfied in autonomous driving scenarios, such as the following two driving scenarios: (a) road types with up and down slopes; (b) road edges with large height fluctuations. The projection results of the algorithm using camera parameters at these positions will have a large deviation from the real annotation, which will lead to a decrease in the accuracy of semantic segmentation in the Bird's-EyeView (BEV) space, and the subsequent road layout estima...
