An image search method based on deep learning

Abstract

The invention discloses an image search method based on deep learning. The image search method greatly enhances the search efficiency through information input, searching strategies, search, result discrimination and output to a GIS database. A traditional image search method is low in query efficiency and reduces work efficiency because collected sample data is huge and the bandwidth and the scaling capacity are limited. The disclosed image search method has the advantages that the accuracy in the image search process and recognition quality are improved through deep learning; the searching strategies include distance and road preceding-following relations, and images can be searched according to specific situations; under the situations like dense roads, the road preceding-following relation search strategy is adopted, the distance search strategy is used in open regions, the quantity of collected data samples are greatly reduced, and the search speed is increased; distributed-type search and centralized-type search can be utilized for the image search, the appropriate search approach is selected according to actual conditions, accordingly the bandwidth and the scaling capacity are saved, and the query efficiency is greatly improved.

Description

【Technical field】

[0001] The present invention relates to the technical field of image search, in particular to an image search method based on deep learning. 【Background technique】

[0002] In current traffic management and road planning, traffic flow and the type and speed of passing vehicles are important parameters. The methods of automatically obtaining these data can be roughly divided into two categories: one is to use sensors such as piezoelectric, infrared, and ring magnetic induction coils to obtain the parameters of the vehicle itself. This method has a high tracking and recognition rate, but is easy to damage and inconvenient to install. ; There is also a method based on image processing and pattern recognition, which overcomes the limitations of the previous method. Due to the advancement of image processing and recognition technology and the substantial increase in hardware cost performance, systems with certain practical value have emerged. The use of these s...
