A Pedestrian Tracking-Based Refueling Gun Location Method

Abstract

The invention discloses a method for locating a fuel gun based on pedestrian tracking, comprising the following steps: S1. After the fuel gun is lifted, a fuel gun sensor sends a signal to trigger an identification system for identification; S2, the identification system collects the current fuel gun through a camera. The image of the place where it is placed, through the pedestrian detection algorithm, the staff is identified from the image; S3, the identified staff is tracked according to the video image; S4, the recognition system collects the image of the fuel level, and identifies whether there is a vehicle in the image; S5 . Calculate the location of the vehicle after identifying the vehicle with the refueling level; S6. Calculate the pre-refueling area according to the set parameters and the location of the vehicle and mark it in the video image; S7. Send a pre-refueling signal when the staff enters the pre-refueling area To start the oil pump to pump oil in advance. The invention makes the judgment of the opening timing of the fuel pump more reliable, effectively saves the fueling time, and prevents the pressure in the system from being too high and reduces the high-pressure time.

Description

technical field [0001] The invention relates to a method for locating a refueling gun based on pedestrian tracking. Background technique [0002] Now visual recognition technology has begun to be widely used, and the technology of identifying people, vehicles and automatic refueling robots through visual recognition technology has also begun to appear in gas stations. However, due to the complex environment of many gas stations and technical limitations, it is rare to fully realize automatic refueling without the need for staff to refuel. In some gas stations, there is a certain distance between the vehicle and the fuel dispenser when refueling. When the distance is relatively long, the fuel dispenser needs to be connected to the refueling gun through a hose that is more than ten to twenty meters long. If the refueling pump is turned on too early during refueling, the pump will All the flow coming up flows back to the oil tank through the overflow valve, which not only caus...

Problems solved by technology

[0003] The purpose of the present invention is to provide a positioning method for refueling guns based on pedestrian tracking, so as to solve the problem that in the prior art, when the distance between the refueling position and the refueling machine is far away, it is impossible to effectively judge the opening time of the refueling pump and to save refueling time. Prevent the problem of high pressure in the system under the premise
