The invention discloses a vehicle re-identification method and device, a training method, electronic equipment and a storage medium, and relates to the field of artificial intelligence, in particularto computer vision, deep learning and intelligent traffic technologies. The specific implementation scheme is as follows: a picture of a target vehicle to be re-identified is acquired, a target two-dimensional image of the target vehicle isdeterminined based on the picture and a preset initial three-dimensional model, the target two-dimensional image is re-identified based on sample three-dimensional information of a sample vehicle, an identification result isgenerated and output, as the sample three-dimensional information comprises the related information which can be used for describing each dimension of each vehicle from a three-dimensional perspective, and when the target two-dimensional image is determined based on the initial three-dimensional model, the target two-dimensional imagecan describe the related information of the target vehicle in detail, therefore, the technical effects of accuracy and reliability of the recognition result determined based on the target two-dimensional image can be achieved.
Description
technical field [0001] The present application relates to the field of artificial intelligence, specifically to computer vision, deep learning and intelligent transportation technology, and in particular to a vehicle re-identification method, device, training method, electronic equipment and storage medium. Background technique [0002] In recent years, as the data captured by surveillance cameras has become larger and larger, the demand for surveillance data analysis capabilities has also increased rapidly. However, compared with the speed of data increase, the development of data analysis technology is far from meeting the requirements. The vehicle re-identification technology aims to make up for the problem of the limited angle of fixed cameras, and can retrieve the required specific vehicles across cameras, which not only saves the steps of manual retrieval, but also improves efficiency. Therefore, reasonable and effective use of vehicle re-identification technology is ...
