Problems solved by technology

Specifically, if the tire pressure of the car tire is too high, the contact area between the tire and the ground will be reduced, and the pressure and wear per unit area will increase sharply, which will easily cause the brakes to lose control, burst when encountering protrusions or depressions on the ground, and damage the suspension system of the car. , ride discomfort and other hazards
If the tire pressure of the car tire is too low, the contact area between the tire and the ground will increase, and the temperature inside the tire will increase abnormally when the car is running. Hidden dangers, and increase fuel consumption and reduce tire life

Embodiment 1

[0017] refer to figure 1 , shows a flowchart of steps of a method for detecting tire pressure according to Embodiment 1 of the present invention. A tire pressure detection method provided by an embodiment of the present invention includes the following steps:

[0018] In step S101, a feature extraction operation is performed on a wheel and tire image to be detected, so as to obtain tire feature data of the wheel and tire image.

[0019] In this embodiment, the tire images to be detected may include tire images of bicycles, electric vehicles, motorcycles, automobiles, and trucks. The feature extraction operation can be understood as an operation performed using image feature extraction technology. The tire characteristic data of the wheel tire image includes at least one of the following: the similarity between the current shape of the wheel tire and the shape of the wheel tire at normal tire pressure, the model of the wheel tire, the wheel tire The model of the wheel hub wh...

Embodiment 2

[0050] refer to Figure 4 , shows a flowchart of the steps of a method for detecting tire pressure according to Embodiment 2 of the present invention. A tire pressure detection method provided by an embodiment of the present invention includes the following steps:

[0051] In step S201, a feature extraction operation is performed on a wheel and tire image to be detected, so as to obtain tire feature data of the wheel and tire image.

[0052] Since the specific implementation manner of step S201 is similar to the specific implementation manner of step S101 in the first embodiment above, details are not repeated here.

[0053] In step S202, based on the first feature data included in the tire feature data, a preliminary judgment is made on the tire pressure of the wheel tire in the wheel tire image, so as to obtain a preliminary judgment result of the tire pressure of the wheel tire.

[0054] Since the specific implementation manner of step S202 is similar to the specific impl...

Embodiment 3

[0072] An embodiment of the present invention also provides a computer storage medium, the computer storage medium stores a readable program, and the readable program includes: performing a feature extraction operation on a wheel and tire image to be detected, so as to obtain the wheel and tire image An instruction of the tire characteristic data; for performing preliminary judgment on the tire pressure of the wheel tire in the wheel tire image based on the first characteristic data included in the tire characteristic data, so as to obtain a preliminary tire pressure information of the wheel tire Instructions for judging results, wherein the first feature data includes the similarity between the current shape of the wheel tire and the shape when the wheel tire is under normal tire pressure; If the tire pressure is normal, predict the tire pressure of the tire in the tire image based on the second characteristic data included in the tire characteristic data, so as to obtain the ...

Abstract

Embodiments of the present invention provide a tire pressure detection method and a computer storage medium. Wherein, the method includes: performing a feature extraction operation on the wheel and tire image to be detected to obtain tire feature data of the wheel and tire image; based on the first feature data included in the tire feature data, performing Preliminary judgment, obtain the preliminary judgment result of the tire pressure of the wheel tire; if the tire pressure of the wheel tire is determined to be normal based on the preliminary judgment result, then based on the second feature data included in the tire feature data, the tire pressure of the wheel tire in the wheel tire image Prediction is performed to obtain a prediction result of the tire pressure of the wheel and tire; based on the prediction result of the tire pressure of the wheel and tire, the tire pressure of the wheel and tire in the image of the wheel and tire is re-judged to obtain a re-judgment result of the tire pressure of the wheel and tire. This embodiment can automatically detect the tire pressure, thereby reducing the possibility of accidents when the vehicle is running at low speed and high speed.

Description

technical field [0001] Embodiments of the present invention relate to the field of artificial intelligence, and in particular to a method for detecting tire pressure and a computer storage medium. Background technique [0002] The car is a means of transportation, and the car tire is one of the important parts of the car. It is in direct contact with the road surface and works together with the car suspension to ease the impact of the car while driving, ensuring that the car has good seating comfort and smooth driving. To ensure good adhesion between the wheels and the road surface, improve the traction, braking and passability of the car, bear the weight of the car, and the important role played by tires on the car has attracted more and more attention. [0003] The safe driving of a car is inseparable from the normal tire pressure of the tire. When the car is running at high speed, if the tire pressure is abnormal, it will have a great impact on the driving safety of the c...
