Abstract

The invention discloses a vehicle searching method and device, electronic equipment and a computer readable storage medium. According to the scheme, the method comprises the following steps: acquiringthe image of a vehicle to be searched; extracting features of the image of the vehicle to be searched through a convolutional neural network to obtain a feature vector; separately carrying out attributive feature extraction and extraction of a deep feature between opposite positive and negative samples on the feature vector; merging the attributive feature and the deep feature to obtain a vehiclevisual feature of the image of the vehicle to be searched; and carrying out matching calculation on a vehicle visual feature between the image in a vehicle search database and the image of the vehicle to be searched and acquiring a target image matched with the image of the vehicle to be searched. By the technical scheme, the accuracy of vehicle search is high, and because artificial query is notrequired, the vehicle search efficiency is high.

Description

Technical field [0001] The present disclosure relates to the field of image recognition technology, and in particular to a vehicle retrieval method and device, electronic equipment, and computer-readable storage medium. Background technique [0002] Retrieving vehicles to be queried from massive surveillance videos has important applications in public security systems. Usually the surveillance system saves hundreds or even tens of thousands of surveillance videos. Retrieving the vehicle to be queried from such a huge video requires a lot of calculations and a long time. The amount of computing required and the time required increase rapidly with the increase in the number of surveillance videos and the expansion of the search time range. [0003] In the prior art, the following two solutions can be adopted for vehicle retrieval in multiple surveillance videos: [0004] Option 1. Manual retrieval method. Checking whether the vehicle to be queried is present through human eyes, this...
