How AI Object Detection Using Waveshare Camera & Raspberry Pi Works

Waveshare camera captures real-time video.
Raspberry Pi processes frames using OpenCV.
TensorFlow Lite model detects objects.
Bounding boxes are drawn.
Detection results are displayed live.
Optional: Alerts or cloud logging.

This is known as Edge AI Processing, where AI runs locally on device without cloud dependency.

Basic Hardware Setup

Connecting Waveshare Camera to Raspberry Pi

• Insert ribbon cable into CSI port
• Blue side of cable should face Ethernet port
• Lock CSI connector firmly
• Enable camera via raspi-config

(No GPIO wiring required)

Software Installation

Step 1: Install Raspberry Pi OS

Download from official Raspberry Pi website:
🔗 https://www.raspberrypi.com/software/

Flash using Raspberry Pi Imager.

Step 2: Enable Camera

sudo raspi-config

Enable Camera → Reboot

Step 3: Install Required Libraries

sudo apt update
sudo apt install python3-opencv
pip3 install tflite-runtime numpy

Official OpenCV documentation:
🔗 https://docs.opencv.org/

TensorFlow Lite documentation:
🔗 https://www.tensorflow.org/lite

Basic AI Object Detection Code (Python)

import cv2
import numpy as np
import tflite_runtime.interpreter as tflite
# Load TFLite model
interpreter = tflite.Interpreter(model_path="detect.tflite")
interpreter.allocate_tensors()
input_details = interpreter.get_input_details()
output_details = interpreter.get_output_details()
cap = cv2.VideoCapture(0)
while True:
    ret, frame = cap.read()
    img = cv2.resize(frame, (300, 300))
    input_data = np.expand_dims(img, axis=0)
    interpreter.set_tensor(input_details[0]['index'], input_data)
    interpreter.invoke()
    boxes = interpreter.get_tensor(output_details[0]['index'])
    classes = interpreter.get_tensor(output_details[1]['index'])
    scores = interpreter.get_tensor(output_details[2]['index'])
    for i in range(len(scores[0])):
        if scores[0][i] > 0.5:
            box = boxes[0][i]
            y1, x1, y2, x2 = box
            h, w, _ = frame.shape
            cv2.rectangle(frame,
                          (int(x1*w), int(y1*h)),
                          (int(x2*w), int(y2*h)),
                          (0,255,0), 2)
    cv2.imshow("AI Detection", frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
cap.release()
cv2.destroyAllWindows()
