Vehicle bottom foreign matter detection method and device, computer equipment and storage medium

Abstract

The invention relates to a vehicle bottom foreign matter detection method and device, computer equipment and a storage medium. The method comprises the steps of obtaining difference data in the collected vehicle bottom information data under the condition that difference exists between the vehicle bottom information data collected by observers installed in a first range around a vehicle and the vehicle bottom information data collected by the observers during parking; determining coordinate information of the difference data, comprehensive detection range information of the observer and vehicle body range information of the vehicle through a coordinate axis, wherein the coordinate axis is established according to a first direction of the vehicle and a second direction perpendicular to the first direction; and according to the relationship between the coordinate information of the difference data and the comprehensive detection range information of the observer as well as the vehicle body range information of the vehicle, determining whether foreign matters exist at the bottom of the vehicle or not. By adopting the method, whether animals or foreign matters of which the body temperature is close to the environment temperature are in the vehicle bottom range or not can be detected.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a method, device, computer equipment, and storage medium for detecting foreign matter at the bottom of a vehicle. Background technique [0002] With the development of social consumption level, more and more families own vehicles, and most of the vehicles are usually parked on the side of the road or in the parking spaces of the community. When stray animals get into the bottom of the car or other foreign objects enter the bottom of the car Difficult to detect, when the vehicle is started, it may cause the death of stray animals and damage to the vehicle. In response to the above problems, infrared detection technology and image detection foreign object technology have emerged. Infrared detection technology uses infrared thermal induction to judge whether there are stray animals around the vehicle, and when stray animals approach the vehicle, an alarm will be...

AI Technical Summary

Problems solved by technology

[0004] However, in actual situations, foreign objects often appear inside the vehicle, such as small animals entering the exhaust pipe of the vehicle or inside the hood of the vehicle. In this case, it is difficult to detect foreign objects by relying on image detection methods

Moreover, based on production costs and vehicle structure limitations, it is difficult to install a full-range coverage camera inside the vehicle

Moreover, the current infrared detection technology has poor penetration, and the ambient temperature will interfere with the infrared detection results. Therefore, when the summer is hot, the detection results will be biased, and it is aimed at the situation where animals with body temperature and ambient temperature are close or foreign objects are under the car. Unable to detect
