A linear CCD camera-guided intelligent vehicle controlled by an STC32G128K microcontroller.

This project aims to design an intelligent car capable of autonomous line following. By integrating multiple advanced sensor technologies and precise control algorithms, it achieves efficient and stable line following functionality.

The intelligent line-following car uses an STC32G128K microcontroller as its core control unit, fully leveraging its powerful computing capabilities and rich interface resources. A CCD camera is used as a data collection sensor, capable of capturing ground trajectory information in real time and accurately. The CCD camera sensor features high resolution and fast response, providing the car with clear and reliable visual input.

To further improve the car's operational stability and attitude control accuracy, attitude sensors such as gyroscopes are also introduced for auxiliary operation. The gyroscope can sense changes in the car's tilt angle and angular velocity in real time, providing the microcontroller with precise attitude data, thereby enabling more accurate dynamic adjustments.

In terms of power drive, the motor's speed and torque are precisely adjusted by controlling the PWM output of the DC motor. The application of PWM technology makes motor control smoother and more efficient, allowing for flexible adjustments to the car's speed and steering according to different road conditions and line-following requirements.

After the car starts, the CCD camera sensor continuously scans the ground trajectory, transmitting the collected data to the microcontroller. The microcontroller quickly processes and analyzes this data, combining it with data from attitude sensors such as gyroscopes to calculate the optimal motor control strategy. Then, it outputs corresponding PWM signals to control the rotation of the DC motor, enabling the car to travel accurately and stably along a predetermined trajectory.
