OpenCV experiment on color and circle detection with a traffic light picture. These techniques will be used to detect traffic lights for the traffic detection in Visioneer. Other OpenCV techniques will also be used for traffic detection.
The image of a traffic light arrow is detected with recognizing the shape of pentagon and rectangle using contour approximation from OpenCV.
Sensor experiment
Here are two videos of the experiment on LIDAR and MPU6050. The first video is testing two TOF LIDARs VL53L0. The conclusion is stable readings and narrow detection range. So we've decided to experiment with Maxbotix Sonar sensor for obstacle avoidance.
The second video is using MPU 6050 to detect movement of a user. Turning on red LED light means a user is stationary and turning on blue LED light means the user is walking or moving. It is a way to switch between two modes in Visioneer.
