Gas station vehicle multi-view positioning method based on 3D visual identification

Abstract

The invention discloses a gas station vehicle multi-view positioning method based on 3D visual identification, and the method comprises the following steps: S1, pre-configuring a plurality of monitoring cameras, and converting a pavement image obtained by the plurality of monitoring cameras into an aerial view; s2, carrying out splicing processing on the plurality of converted aerial views; s3, adopting an FCOS3D algorithm and combining an internal reference matrix of the monitoring camera to complete identification of a vehicle 3D detection frame; and S4, converting the bottom surface coordinates of the vehicle 3D detection frame, and performing detection frame de-weighting after conversion. Multi-camera vehicle detection of a gas station is achieved, the situation that a general simple license plate recognition function system based on 2D images is low in expandability and too high in cost is effectively relieved, a foundation is laid for intelligent functions such as follow-up vehicle identity recognition and tracking, non-inductive payment and algorithm oil gun distribution, existing monitoring equipment is utilized to the maximum degree, and the working efficiency is improved. And the intelligent reconstruction cost is obviously reduced.

Description

technical field [0001] The invention relates to the field of visual recognition, in particular to a multi-view positioning method for vehicles in gas stations based on 3D visual recognition. Background technique [0002] With the improvement of people's living standards, gas stations are often faced with huge business pressure on the efficiency of refueling. Users often wait too long, the refueling process is too long, and equipment scheduling and management are inefficient. At the same time, analyzing the heat distribution map of vehicle data, predicting the peaks and troughs of gas station business, easily predicting queuing time, flexibly adjusting marketing strategies, and intelligently managing gas equipment and other needs have gradually become the goals of the upgrading and development of smart gas stations. [0003] At present, the construction method of smart gas stations is generally based on installing a camera near the fuel gun to identify the license plate infor...
