A study of image recognition intelligent small car system

With the rapid development of modern science and technology, control technology and theory have made great progress, the development of industrial automation is more and more rapid, the degree of automation is also higher and higher, and the scope of use has also been greatly expanded. Under the influence of the rapidly developing micro controller technology, the technology covers many disciplines including sensor technology. This design is under the background of hardware selection and software design to realize the image recognition intelligent car system. The intelligent car system designed by the design can realize a variety of functions, including image recognition, Bluetooth remote control, voice broadcast, ultrasonic obstacle avoidance, speech recognition, autonomous tracking, gesture recognition, ultrasonic speed measurement, OLED screen display and other functions. The design of the camera on the OpenMV module are used to collect images, and identify and process them. If the target image is identified, send data to the microcontroller through the established serial port communication protocol, and the microcontroller performs the next operation. The car has added a LD3320 voice recognition module, which can distinguish the sound of people, and can control the car driving through the sound. The car can be remotely controlled through the HC-05 Bluetooth module, and each module can be selected through the Bluetooth. Through the ATK-PAJ7620 gesture recognition module, the car can recognize our gestures and realize the corresponding functions. The TCRT5000L tracking sensor can detect the black track on the ground, and the ultrasonic HC-SR 04 sensor is added in the front position for distance detection. The module transmits the collected relevant data to the main control, so as to realize the autonomous tracking of the car and the function of avoiding obstacles. Speed measurement can also be performed by the ultrasonic module, and the speed results can be displayed on the OLED screen. The design integrates the various modules and implements the above functions. The design and research and development of these functions greatly improve the practical value of smart cars, which can be applied to driverless cars, modern logistics, service industry and many other fields, to bring better experience to people, it is of great significance to the development of intelligent vehicles in China.
