Embodiment Construction

[0017] The present invention will be described in detail below in combination with specific embodiments.

[0018] The processor of the system sends the control bus signal to the imaging module, and at the same time uses the interrupt method to read the image, obtains the track image information through the high-resolution imaging module, collects the changes of the external environment, and returns a complete image, so that the system can obtain In the current state, at the same time, hardware binarization is adopted to control the operation of the device through the SCCB bus, and the high-speed DMA channel is used to directly read the image data; image preprocessing is performed in the processor, and the steering of the steering gear is controlled through the pulse width modulation signal and driving the motor; the speed measuring device reads the square wave signal with a certain frequency converted from the photoelectric signal, and at the same time determines the two pulse ...

Abstract

The invention discloses an intelligent car path recognition method based on a black and white camera. The processor sends the control bus signal to the imaging module, and at the same time reads the image by means of an interruption, obtains the image information of the track through the high-resolution imaging module, and collects the information of the external environment. Change, return a complete image, so that the system can obtain the current state, and at the same time use hardware binarization, control the operation of the device through the SCCB bus, use the high-speed DMA channel to directly read the image data; perform image preprocessing in the processor , control the steering of the steering gear and the advancement of the drive motor through the pulse width modulation signal; the speed measuring device reads the square wave signal with a certain frequency converted from the photoelectric signal, and at the same time determines the current needs to be given according to the corresponding characteristic value of the square wave signal. Repeat the steps for the two PWM signals of the motor and the servo. The beneficial effect of the invention is that two functions of automatic tracking and obstacle avoidance can be realized.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a path recognition method for a smart car based on a black and white camera. Background technique [0002] Intelligent vehicles, also called unmanned vehicles, are a comprehensive system that integrates environmental perception, planning and decision-making, and multi-level assisted driving. It has functions such as automatic identification of road obstacles, automatic alarm, automatic braking, automatic maintenance of a safe distance, vehicle speed and cruise control. The main feature of an intelligent vehicle is that it can automatically maneuver and drive the vehicle around obstacles and travel along a predetermined road (trajectory) under complex road conditions. Intelligent vehicles have an intelligent perception system, which uses various sensors to obtain the status information of the vehicle itself, the surrounding environment of the vehicle, and the driver itself, and...
