Abstract

The embodiment of the invention provides an image retrieval method and device, and solves the problem that accuracy can be improved since certain specific characteristics are required as assistance during retrieval because an existing retrieval method is low in accuracy. The image retrieval method comprises the following steps that: extracting a first depth characteristic from an image to be retrieved, and extracting a first local characteristic from the image to be retrieved; independently matching the first depth characteristic and the first local characteristic with the second depth characteristics and the second local characteristics of a plurality of candidate images stored in a characteristic database to obtain the matched second depth characteristic and second local characteristic;and outputting an image corresponding to the matched second depth characteristic and second local characteristic.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to an image retrieval method and device. Background technique [0002] Road surveillance probes and cameras are now all over the street checkpoints. Public security and traffic systems need to rely heavily on the image data collected by these monitoring probes in various security tasks such as dispatching and criminal investigation. However, for a large amount of video image data, it is not only inefficient to find targets from these video image data only by manpower, but also requires a lot of manpower and material resources, and the cost is high. [0003] Although the existing technology can use these large amounts of video image data for target retrieval by using deep learning, the accuracy is often low, because some specific features are needed as assistance in the retrieval to improve the accuracy. The image retrieval method provided by the present invention can In the case o...
