Moving Object Detection using Micro:bit

Detection and tracking of a moving object

The detection and tracking of a moving object is a key area in computer vision, with applications ranging from video surveillance and autonomous vehicles to augmented reality and human-computer interaction.

Steps in Object Detection and Tracking

1- Preprocessing:

Convert the video to grayscale (optional, for efficiency).

Apply noise reduction techniques, such as Gaussian blur, to smooth frames.

2- Object Detection:

Use a detection algorithm to identify objects of interest in the frame.

Extract object boundaries (e.g., bounding boxes).

3- Feature Extraction:

Extract features (e.g., edges, corners, textures) from the detected object.

4- Object Tracking:

Match the detected object across frames using motion models, appearance features, or both.

Update the object's position and state in real time.

5- Postprocessing:

Refine tracking results to remove false positives/negatives.

Handle occlusion, illumination changes, and other real-world challenges.

Moving Object Detection using Micro:bit

To implement moving object detection using a BBC micro:bit, webcam, servo motor, and a computer, you'll need to design a system that integrates object detection on the computer, controls the servo motor for object tracking, and uses the micro:bit as a communication interface between the computer and the motor.

Hardware Required

BBC Micro:bit: Acts as the interface between the computer and the servo motor.

Webcam: Captures video for detecting a moving object.

Servo Motor: Moves to follow the detected object.

Computer: Performs object detection and controls the motor via the micro:bit.

USB Cables: For connecting the micro:bit to the computer.

Jumper Wires: For connecting the servo motor to the micro:bit.

Running the System

1- Connect the webcam to the computer and the micro:bit via USB.

2- Run the Python object detection script on your computer.

3- The webcam will detect the moving object and send commands to the micro:bit to move the servo motor accordingly.
