Small-scale pedestrian target rapid super-resolution method for intelligent roadside equipment

Abstract

The invention discloses a small-scale pedestrian target rapid super-resolution method for intelligent roadside equipment. The method comprises the steps of collecting and constructing a small-scale pedestrian high-low resolution data training set; based on a generative adversarial idea, building a lightweight generative network for a low-resolution small-scale pedestrian image. The network firstlyuses separable convolution to extract image preliminary features, then combines a residual module to fit high-frequency information, and finally uses a pixel recombination module to perform high-resolution reconstruction on the low-resolution pedestrian image. A discrimination network is built, and discrimination training is performed on the parameters of the generation network to obtain an optimal generation network; and super-resolution on the low-resolution small-scale pedestrian picture is performed by using the optimal generation network to obtain a high-resolution pedestrian target. Thelightweight super-resolution generation network designed by the invention has the remarkable advantages of short training time and low reasoning delay, and fills the technical gap of small-scale pedestrian real-time super-resolution in the field of intelligent roadsides.

Description

technical field [0001] The invention belongs to the field of computer vision and intelligent transportation, and relates to a super-resolution method for small-scale pedestrian targets in intelligent traffic roadside scene images, in particular to a fast super-resolution method for small-scale pedestrian targets for intelligent roadside equipment. Background technique [0002] With the rapid growth of my country's road traffic scale, frequent traffic accidents between pedestrians and vehicles, the safety performance of vehicles has been continuously improved, but the safety equipment for pedestrians has been in a lack of state. In order to ensure the basic safety of pedestrians, the intelligent roadside system, which uses electronic information technology to assist pedestrians to provide safety warnings to surrounding drivers or smart cars, has become the focus of research at home and abroad. Among them, the accurate recognition of small-scale pedestrians is a prerequisite f...

Problems solved by technology

[0004] However, due to the complexity of the network structure, the existing deep learning super-resolution methods all have a serious problem that the algorithm execution time is too long, and it is difficult to be directly used in intelligent roadside equipment with high real-time requirements.
