Scarlet 3D Depth Camera

High Resolution 3D Depth Sensing in Real-Time Enters the Next Round

Scarlet 3D Depth Camera: the Next Generation of 3D Depth Perception

We supply the vision for your application and continue to be the pioneer of the 3D stereo vision market:

With up to 120 fps and over 70 million 3D points per second, Scarlet offers by far the fastest 3D measurement rate in the machine vision market. In addition, Scarlet achieves an excellent resolution of up to 5 megapixels in camera and depth image.

Scarlet combines 3D stereo camera and image processing in one device. Whether for static environments, or hard and critical real-time applications in dynamic environments, our Scarlet 3D depth camera provides you with exactly the image and depth data you need for your machine vision application.

For the moment, Scarlet is available as a monochrome 3D depth camera, the version with color sensor is planned for mid 2021.

Fields of application

Do you have a highly time-critical machine vision application?

Accurate real-time image processing at 5 MP resolution

The Scarlet 3D depth camera beats our predecessor system by a factor of 2.5, at frame rates of up to 120 fps and resolution of up to 5 MP. In addition, Scarlet can process a disparity range twice as large, which leads to a doubling of the depth resolution. So with our Scarlet you can achieve even more precise 3D measurement results for your machine vision application.
 

Machine vision for agriculture or in autonomous vehicles?

IP67 protection

With ingress protection rating IP67, the device is optimally suited for outdoor use or in dusty environments. Thanks to the chemically tempered glass window, the high-resolution optics remain protected even in very harsh environments.

Inertial sensor (IMU)

In addition, Scarlet integrates an extremely fast inertial measurement unit (IMU), which records motion data at up to 400 Hz. Inertial data is particularly valuable for mobile robotics applications such as Simultaneous Localization And Mapping (SLAM). Scarlet eliminates the need for a separate IMU.
 

3D depth perception for bin picking applications?

Combination with a pattern projector

Bin picking applications often have several critical factors: precision,speed and, above all, often a difficult surface structure of the objects to be measured, e.g. smooth or reflective. In combination with the Effi-Lase pattern projector, our Scarlet 3D depth camera can easily provide your robot with a clear view.
 

You have special requirements regarding field of view or measuring distance?

High flexibility

Scarlet is available in two models: with 10 cm baseline distance or 25 cm baseline distance between the cameras. Both models have the same functionality and processing power, but differ in the measuring range. Thanks to a wide range of lenses, Scarlet can be easily configured to meet your needs.

Depth measurement examples

As with our SceneScan stereo vision sensor, the image data is processed in real-time using a powerful FPGA and our advanced stereo algorithm. The processing result is a sub-pixel accurate disparity map (an inverse depth image), which is transmitted to a computer or embedded system via 1 or 10 Gigabit Ethernet. Our open source and cross-platform API converts this disparity map into a dense 3D point cloud. Our automatic re-calibration ensures the functionality of the sensor system even under mechanical stress and a long operating time.

You still have questions?

The maximum frame rate depends on the selected image resolution and depth resolution (the disparity range). We recommend using one of the following configurations. However, different configurations are also possible.

Recommended configurations

Thanks to a wide range of lenses, Scarlet can be easily configured to meet your requirements. By choosing a suitable camera setup and the corresponding baseline distance, very different measuring ranges can be covered. It is also possible to choose between a high frame rate or a high image or depth resolution. Frame rates up to 120 fps and resolutions up to 5 megapixels are possible. We are happy to support our customers in finding the optimal configuration for a specific application.

The FPGA design used in Scarlet can also be licensed as IP core.

Below you will find a list of recommended configurations:

The values are valid for operation via the 10 Gigabit Ethernet interface with the simultaneous output of the disparity map and the left camera image, or for operation via the 1 Gigabit interface and output of the disparity map, without camera image.
