Traffic Sign Detection¶
This project uses an image detection function to look for traffic signs, and make the PiCar-X follow the instructions on the sign. The turn traffic sign detection [on] block will recognize 4 different traffic sign models included in the printable PDF below. When the PiCar-X detects a STOP sign, it will come to a stop, a FORWARD sign will make it drive forward, and the LEFT or RIGHT arrows will make it turn that direction.
The printed traffic sign colors may have a slightly different hue from the Ezblock color models due to printer toner differences, or the printed medium, such as a tan-colored paper. This can cause a less accurate color recognition.
This project is based on Minecart, but instead of using the grayscale sensor, the PiCar-X uses an algorithm for traffic sign detection. The detection results can be viewed via the Video Monitor in Ezblock Studio.
You can write the program according to the following picture, please refer to the tutorial: How to Create a New Project?.
