Problems solved by technology

[0003] However, in the case of uneven illumination in the image, when long-exposure and short-exposure images are subjected to wide dynamic fusion, due to the differences of each target in the image, there are still some targets in the wide dynamic fusion image obtained after wide dynamic fusion. The overexposure or underexposure of the wide dynamic fusion image leads to the loss of some details in the wide dynamic fusion image, so that the recognition accuracy is not high enough when performing image recognition based on the wide dynamic fusion image

[0144] see Figure 7 , Figure 7 An example diagram of image recognition performed by the computer system in the car in the embodiment of the present application, including:

[0145] When the image recognition method of the present application is applied to an in-vehicle computer system of an unmanned vehicle, images of the surrounding environment of the vehicle can be collected through a camera on the vehicle connected to the in-vehicle computer system.

[0146] Multiple long-frame images and short-frame images can be collected for the same scene through the camera on the unmanned vehicle. For the collected long-frame images and short-frame images, feature extraction can be selected, and then feature images can be fused by channel superposition and other methods to obtain The images are fused to obtain a fused image, or the long-frame image and the short-frame image can be directly fused to obtain a fused image.

[0147] Through the fused images, the computer system in the ...

Abstract

The embodiment of the invention provides an image recognition method and device, electronic equipment and a storage medium provided by the embodiment of the invention. The method includes: obtaining at least two groups of single exposure image information within a frame of time, wherein each group of single exposure image information is image information obtained in a single exposure process; superposing the at least two groups of single exposure image information; and performing target object identification on the superposed image based on the object category which may occur in the preset scene. The method does not need to carry out the recognition after wide dynamic fusion, avoids a problem that the recognition accuracy is not high enough because of the loss of a part of details in a wide dynamic fusion process, and can improve the accuracy of image recognition.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image recognition method, device, electronic equipment and storage medium. Background technique [0002] At present, image recognition has been widely used. For example, in the field of automatic driving technology, through the recognition of real-time acquired images, traffic signs at intersections can be recognized, and corresponding measures such as steering and braking can be taken. When performing image recognition, in order to obtain the detailed features of high-light areas and low-light areas, wide dynamic fusion is first used to fuse long-exposure long-frame images and short-exposure short-frame images, and then perform image recognition based on the fused images. Image Identification. [0003] However, in the case of uneven illumination in the image, when long-exposure and short-exposure images are subjected to wide dynamic fusion, due to the differ...
