1. Time of Flight (ToF) Sensors
Time of Flight (ToF) sensors are among the most popular 3D sensor technologies. These sensors work by emitting light pulses and measuring the time it takes for them to bounce back after hitting an object. The time measurement is then used to calculate the distance to the object, generating depth information. ToF sensors are commonly found in smartphones for face recognition and augmented reality applications.
2. Structured Light Sensors
Structured light sensors project a pattern of light onto an object and use a camera to capture the deformation of that pattern caused by the object’s surface. This method is particularly effective for 3D scanning, facial recognition, and other precision applications.
3. Stereo Vision Sensors
Stereo vision sensors use two or more cameras to capture images from slightly different angles. By analyzing the disparity between these images, the sensor can compute the depth information of the scene. This technique is widely used in robotics, drones, and autonomous vehicles.
4. LIDAR Sensors
LIDAR (Light Detection and Ranging) sensors use laser pulses to measure distances to objects. The laser pulse reflects off objects and returns to the sensor, enabling it to create high-resolution 3D maps of the environment. LIDAR sensors are crucial for autonomous driving, environmental mapping, and industrial automation.
