A 3D camera is an imaging tool that allows images to simulate three dimensions as perceived by human binocular vision in terms of depth perception. A single lens that changes position is used by some 3D cameras, while others use two or more lenses to record multiple points of view.
A camera with two or more lenses and a separate image sensor or film frame for each lens is called a stereo camera. By simulating human binocular vision, stereo photography—a technique that enables the camera to record three-dimensional images—is made possible.
In order to provide us with precise, real-time depth awareness, stereo cameras closely mimic the way our eyes function. It accomplishes this by triangulating related pixels from both 2D planes using two sensors placed a certain distance apart. Each pixel in a digital camera image gathers light that travels along a 3D ray and enters the camera.
The Global 3D stereo camera market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.

The Ensenso N20 camera by Imaging Development System (IDS) features two high-resolution 1.3 megapixel global shutter sensors and a gigabit Ethernet interface. The newly built Ensenso N20 expands on the USB 2.0 Ensenso N10 by offering a broader field of view and volume capture up to 3 metres away from the working distance.
Blue LEDs and high resolution sensors are incorporated into the N20 to offer 3D data with challenging surfaces.Cable lengths of up to 100 metres are possible with the gigabit Ethernet interface. Without a separate outlet, the camera is powered over Ethernet. The projected texture stereo vision principle is used by Ensenso N20.
An integrated projector uses a random point pattern to enhance structures that aren’t or are just faintly visible on the object to be photographed. N20 has an aluminium housing that measures 175 x 50 x 50 mm with screw-in connections. N20 comes in a variety of focal lengths and is already calibrated for usage.
The ZEISS OPMI PENTERO 900 is a 3D stereo camera made by ZEISS that is intended for use in microsurgery and other medical procedures. Surgery may be carried out with increased accuracy and precision because of the high-resolution 3D pictures provided by this camera.
The dual-channel video camera technology in the ZEISS OPMI PENTERO 900 creates a stereoscopic 3D image with depth awareness and enables the surgeon to see the anatomy in three dimensions by taking pictures from two separate views. The surgeon may easily change the image’s magnification and focus thanks to the camera system’s inbuilt zoom and focus features.
The ZEISS OPMI PENTERO 900 has a number of other elements besides the camera system that are intended to improve the surgical process. A high-speed xenon light source that delivers brilliant, uniform lighting is one of them. Another is an ergonomic control system that makes it easy for the surgeon to change the camera settings and other settings.
The ZED 3D stereo camera is among the most well-known items produced by Stereolabs. High-definition 3D photos and videos are captured using two sensors by the ZED camera, a small and lightweight gadget. Robotics, augmented and virtual reality, 3D scanning, and driverless cars are just a few of the many applications it is made for. The ZED camera has a distinctive design that enables it to simultaneously record depth and color data.
The data from the two sensors is combined to build a comprehensive 3D map of the surroundings using a specially created stereo algorithm, which is how this is accomplished.
The camera has a variety of sophisticated capabilities that enable users to tailor its performance for their particular purpose, such as a customizable baseline, exposure control, and depth range.
It is also simple to incorporate into current processes because it supports a variety of programming languages, including C++, Python, and ROS. The ZED Mini, a scaled-down version of the ZED camera made for use with laptops and desktop PCs, is another item that Stereolabs sells. Many of the same features found in the larger ZED camera are also available in the smaller, more portable ZED Mini.
