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

A black-and-white camera-based intelligent dolly path identification system disclosed by the present invention is characterized by executing according to the following steps of using a processor to send a control bus signal to an imaging module, at the same time, reading an image in an interruption manner, obtaining the track image information via a high resolution imaging module, acquiring the change of the external environment, returning a frame of complete image, enabling the system to obtain the current state, at the same time, controlling the operation of a device by adopting the hardware binarization and by an SCCB, and using a high-speed DMA channel to read the data of the image directly; carrying out the image pre-processing in the processor, and controlling the steering of a steering engine and the advancing of a driving motor via a PWM signal; using a speed measurement device to read a square wave signal having a certain frequency and formed by the photoelectric signal conversion, at the same time, determining two types of PWM signals needing to be given to the outside world at present according to the corresponding feature values, and repeating the steps. The beneficial effect of the present invention is that the black-and-white camera-based intelligent dolly path identification system can realize the two functions of tracking automatically and avoiding obstacles.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to an intelligent car path recognition system 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, an...
