How to Use 3D DEPTH CAMERA: Examples, Pinouts, and Specs
Design with 3D DEPTH CAMERA in Cirkit DesignerIntroduction
The Raspberry Pi 3D Depth Camera is an advanced imaging device capable of capturing spatial information to perceive depth and create three-dimensional representations of the environment. This camera is particularly useful in applications such as robotics, gesture recognition, 3D scanning, and augmented reality.

Arduino-Based Depth and Environmental Monitor with LCD Display and Buzzer Alert
This circuit uses an Arduino UNO to measure depth, humidity, and temperature using an HC-SR04 ultrasonic sensor and a DHT11 sensor. The measurements are displayed on a 16x2 I2C LCD, and a piezo buzzer is activated if the depth is less than 5 cm.

This circuit features an ESP32-CAM module connected to an HC-SR04 ultrasonic distance sensor and a red LED, powered by a 3xAAA battery pack. The ESP32-CAM reads QR codes and controls the LED based on the distance measured by the ultrasonic sensor, turning the LED on if an object is detected within 10 cm.

This circuit is designed to monitor eye pressure and deformation using a photodiode, a TCRT 5000 IR sensor, and a VL53L0X time-of-flight distance sensor. The ESP32 microcontroller reads sensor data, processes it to determine eye pressure status, and displays the results on a 0.96" OLED screen. It includes safety features, sensor calibration, and the ability to display sensor values and eye pressure status in real-time.

This circuit features a Raspberry Pi 5 connected to a camera module and a TF LUNA LIDAR sensor for visual and distance sensing capabilities. A Mini 360 Buck Converter is used to regulate power from a Li-ion battery to the Raspberry Pi and an Adafruit Motor Shield, which controls four DC motors. The Arduino UNO microcontroller appears to be unused in the current configuration.

Q: What is the maximum range of the camera? A: The effective range varies based on lighting and the reflective properties of the objects being scanned.
Example Code for Raspberry Pi
Below is an example code snippet for initializing the 3D Depth Camera with a Raspberry Pi using Python. This assumes you have the appropriate libraries installed.
import depth_camera_library
Initialize the camera
camera = depth_camera_library.initialize()
Set up the camera parameters (if necessary)
camera.set_parameters({ 'resolution': 'high', 'range_mode': 'extended' })
Capture a depth frame
frame = camera.capture_depth_frame()
Process the frame (this will vary based on your application)
depth_image = frame.get_depth_image()
Display the depth image (this is just an example)
depth_camera_library.display_image(depth_image)
Always properly close the camera when done
camera.close()
Remember to replace `depth_camera_library` with the actual library provided by the manufacturer for the 3D Depth Camera.
**Note:** The above code is for illustrative purposes only and may not directly correspond to the actual API provided by the Raspberry Pi 3D Depth Camera. Always refer to the manufacturer's documentation for the correct usage and functions.
