We at Stereolabs truly believe in developing cutting-edge world-class cameras and software solutions. This has been at the very core of our mission since we set up shop in 2010.

Over the course of the past decade, you have placed your trust in us, and our products. We are genuinely extremely delighted by the overwhelmingly positive responses you have given us, and which has helped us grow to a family of 8900+ clients worldwide, doing amazing and mind-blowing things in the field of computer vision, artificial intelligence, robotics across many industries like medical, supply chain, autonomous vehicles, drones to name a few.

IP-66 certified Stereocamera

Being one of the leaders in designing stereoscopic 3D cameras, our customers always approached us to make a more resistant camera that could withstand harsh environments and ecosystems. As we strive to meet the customer demands with perfection, we are introducing a new camera called the ZED 2i.

The ZED 2i is a result of 2 years of rigorous research and development by our engineers to bring you the best stereoscopic and robust 3D camera in the market.

The ZED 2i is an IP-66 certified stereoscopic 3D camera that is capable of solving and meeting all your needs with its powerful trailblazing technology and industry-leading specifications. The new ZED 2i is a perfect amalgamation which combines an advanced AI engine based on neural nets, extensive sensor hardware and industry-leading stereo vision technology to deliver an unmatched solution in 3D spatial perception for all your application and use-cases.

Features of ZED2i:

Beautiful design + Powerful hardware + Intelligent software = Unrivaled in terms of performance, functionality and design

A 120° Wide-Angle FOV allows tracking visual landmarks over longer periods increasing the precision of pose estimation and simultaneously it also increases robustness since the visual overlap between subsequent images is larger.

Stereoscopic 360° capture with 6 degrees of freedom for immersive image and video capture.

Extensive Sensor stack in the camera with Motion, IMU, Gyroscope, Accelerometer, Magnetometer, Temperature, Barometer sensors to capture every data point you need for the mind the next-generation application that redefines the 21st century.

IP-66 certified ZED 2i can tolerate severe environments with high shock and vibration, wide temperature, high particulate content, and water ingress, increasing the survivability and durability of the camera. The ZED 2i can be used for building stunning underwater applications as its design allows it to be submerged up to a depth of 1m for up to 30 minutes.

Electronically synchronized rolling shutter to capture accurate and consistent true life-like images and videos without having to worry about constraints like lighting conditions.

Multiple OS supported with Windows, Ubuntu, Debian, CentOS (via Docker), Jetson L4T giving you the flexibility to choose the one you are most comfortable using the camera with.

Cloud-connected: — The ZED 2i can be connected to a cloud platform that lets you monitor and control your camera remotely from anywhere in the world. Capture and analyze spatial data with just a click of a button with our GDPR compliant solution.

Mounting options: — Ever wondered: “How did they mount the camera to get this beautiful photo or video??” The ZED 2i offers multiple mounting options to cater to all your needs. Simply mount it, snap together the connectors, and use it anywhere to take those mind-blowing shots from the ZED 2i.

High-Resolution images from 2K,1080P, 720P and VGA with upto 100FPS to never miss any details in the images.

Improved camera controls including gamma correction, auto exposure and gain ROI window selection.

Enhanced low light vision with an f/1.8 aperture and improved ISP, capturing 40% more light in dark environments.

Improved factory calibration with the new multi-sensor 6-axis robotic calibration process

Capture accurate 3D Depth data up to 20m.

Usecases for ZED2i:

The ZED 2i is a fully GDPR compliant sensor and along with the SDK, it is capable of:

Skeleton Tracking for targeted and relatively accurate interaction with the graphics on the large screens.

People Counting: Counting the number of people located in a particular area of the arena

Queue Management: People queuing up in a cafeteria or for tickets to an attraction.

Social Distancing: Calculating the distance between 2 people. Maintaining minimum distance for security and safety of people located in a particular space.

Fall Detection: Detecting people falling on the floor to avoid any grave injuries.

Route heatmaps: Tracking the person across the areas and generating a path/route of all the areas traversed by the person in the buildings.

Virtual Fencing: Creating virtual Fences to isolate a particular area for people counting and building interactive fun experiences for people in that specified virtual fence.

Occupancy Maps: Generating occupancy/heat maps to detect and recognize the most crowded spaces in the area.

Object Detection:Object detection is the ability to identify objects present in an image. Thanks to depth sensing and 3D information, the ZED camera is able to provide the 2D and 3D position of the objects in the scene.

3D Spatial Mapping: Spatial mapping (also called 3D reconstruction) is the ability to create a 3D map of the environment. It allows a device to understand and interact with the real world. Spatial mapping is useful for collision avoidance, motion planning, and realistic blending of the real and virtual world

Positional Tracking:Positional tracking is the ability of a device to estimate its position relative to the world around it. Also called motion tracking or match moving in the movie industry, this is used to track the movement of a camera or user in 3D space with six degrees of freedom (6DoF)

Applications available with the ZED2i

Testimonials:

If you do not believe that such a powerful, beautiful and intelligent camera exists for just $499 with a 2-year warranty, ask our clients who have experienced the magic the ZED 2i has done for them.

The cameras are working great, the fact they are IP rated is extremely helpful. We had the no-IP-rated ones on our last robot and had to spend extra money and effort making them outdoor proof.

- Used in robots for autonomous weeding in farms.

The ZED 2i perfectly combines the stereoscopic human vision with neural networks, leaving you mesmerized with its beautiful images and videos.

- Used in drone for city mapping

We’re massive fans of the Zed line of cameras and specifically the new Zed 2i. We’re using them in combination with the NVIDIA Jetson Xavier NX (and TX2) platform. We’re integrating them into our robots and using them to do object detection, depth mapping, and helping us perform path planning. We’re also using them with ROS Melodic

- Used for autonomous robotics
