I. The ZED Stereo Camera: An Overview

The ZED Stereo Camera, developed by Stereolabs, is a cutting-edge depth-sensing camera that utilizes stereo vision technology to perceive the world in three dimensions. Unlike traditional monocular cameras that capture flat 2D images, stereo cameras feature two lenses, mimicking human binocular vision. This dual-lens setup allows the camera to capture depth information by comparing the disparities between corresponding points in the two images.

A. Technical Specifications

• Resolution: The ZED Stereo Camera comes in various models, with resolutions ranging from 2K to 4K, ensuring high-quality image and depth data.

• Depth Range: It offers an impressive depth range of up to 40 meters, making it suitable for both close-range and long-range applications.

• Frame Rate: With frame rates of up to 100 frames per second, the ZED Camera can capture fast-moving objects with precision.

• Sensors: Equipped with a global shutter and integrated IMU (Inertial Measurement Unit), the camera can handle dynamic environments and generate accurate depth maps.

B. How It Works

The ZED Stereo Camera operates on the principles of triangulation. By comparing the disparities in pixel positions between the left and right images, it calculates the depth of each pixel in the scene. This information is then used to create a dense point cloud or depth map, enabling accurate 3D reconstruction of the environment.
