Vehicle bottom region monitoring device and method

Abstract

The invention relates to the technical field of vehicle active safety and discloses a vehicle bottom region monitoring device and method. The vehicle bottom region monitoring device comprises an infrared sensor, a Fresnel lens, N cameras, a processing chip and a display device. The Fresnel lens is located in front of the infrared sensor. The infrared sensor, the cameras and the display device are in communication connection with the processing chip. The processing chip is used for triggering the cameras when the infrared sensor detects that the temperature of a vehicle bottom changes and transmitting vehicle bottom region information collected by the cameras to the display device. N is a natural number. The sensitivity of the monitoring device is improved. Abnormal conditions of a complicated condition region at the vehicle bottom are acquired accurately in time by detecting the micro technology changes of the vehicle bottom region so as to protect small animals hiding under vehicles against injuries.

Description

technical field [0001] The invention relates to the technical field of vehicle active safety, in particular to the monitoring technology of the vehicle bottom area. Background technique [0002] At present, more and more people own cars, and people use cars more and more frequently. Parked cars are often seen in residential areas and on both sides of the road. While cars bring convenience to people's travel, there are also some troubles or potential safety hazards for users. [0003] Especially every winter, car owners will find that some small animals such as kittens and puppies hide under the car for heating, and sometimes playful children hide under the car. Usually, the car driver needs to inspect the car before driving to check whether there are some small animals or other objects at the bottom of the car. However, in real life, on the one hand, the driver often neglects to check the bottom of the car. , due to the complex environment under the car, even if the driver...

Problems solved by technology

Usually, the car driver needs to inspect the car before driving to check whether there are some small animals or other objects at the bottom of the car. However, in real life, on the one hand, the driver often neglects to check the bottom of the car. , due to the complex environment under the car, even if the driver checks, the small animals for heating are not always found in time, so how can we find and drive the animals under the car in time before starting the car, and call out the greedy animals under the car? There is no reliable method for children playing to avoid unnecessary accidental injuries
