Problems solved by technology

[0004] 1. The steering wheel angle sensor is directly fixed on the steering wheel or the steering wheel shaft of the vehicle, which will block the driver's view of the instrument, and may affect the rotation of the steering wheel, affecting the driver's normal driving;
[0005] 2. The existing steering wheel angle sensor has no angle memory function, so when the steering wheel turns more

Embodiment Construction

[0066] The present invention will be further described below in conjunction with the drawings.

[0067] The present invention is an image-based vehicle steering wheel angle detection method, which is implemented through the following steps, such as figure 1 Shown:

[0068] Step 1: Mark the steering wheel;

[0069] When the vehicle steering wheel is in the initial state, the marking line 101, marking sticker A102 and marking sticker B103 are pasted on the back circumference of the vehicle steering wheel, such as figure 2 Shown.

[0070] There are 6 marking lines 101. The back circle of the steering wheel is equally divided by 6 marking lines 101 pointing to the center of the vehicle steering wheel, so that 6 equal arc sections are formed on the circumference of the steering wheel back, and the vehicle steering wheel is in the initial state. , A marking line 101 is located directly above the back of the vehicle steering wheel as the zero degree line of the vehicle steering wheel. In t...

Abstract

The invention provides a method and device for detecting the rotation angle of a vehicle steering wheel based on an image, and belongs to the technical field of automobiles. The steering wheel is marked, and then a marking image is obtained and identified, so that the rotation direction of the steering wheel and the rotation angle of the steering wheel are judged. By the method, the rotation angle of the steering wheel can be detected in real time, the detection result is accurate, and when the rotation angle of the steering wheel is more than one circle, the rotation angle of the steering wheel is also accurately obtained; by the device, sight of a driver for observing an instrument is not blocked; and the device is convenient to install and demount and strong in portability, and experimental requirements of conventional vehicles are met.

Description

Technical field [0001] The invention relates to the field of automobile detection, in particular to an image-based vehicle steering wheel angle detection method and detection device, which are used in various vehicle experiments. Background technique [0002] The steering wheel angle sensor is used to measure the rotation angle of the steering wheel when turning. The steering wheel angle sensor adopts the principles of photoelectric effect, resistance partial pressure effect, etc., which corresponds to the photoelectric code or resistance value, and achieves the purpose of collecting the steering wheel angle through photoelectric code identification and resistance value detection. The angle sensor is directly fixed on the steering wheel shaft. [0003] But there are many problems with this design, as follows: [0004] 1. The steering wheel angle sensor is directly fixed on the vehicle steering wheel or the steering wheel shaft, which will cause the driver's line of sight to see the...
