Why the FRAMOS D400e is the Right Choice for Industrial 3D Vision 

At the core of industrial automation and the Internet of Things (IoT), systems are 3D cameras – technology enabling interconnected and automated processes in production lines, warehouses, and industrial facilities.

3D cameras deliver information about an object’s shape, distance, position, and degree of rotation in real-time. It enables robots to make informed decisions, select objects, handle them safely, and avoid collisions.

On top of the high-quality image and reliable, fast, and stable connection required by any vision application, industrial 3D vision solutions have another set of challenges to overcome.

A harsh industrial environment could be problematic for the sensitive electronic components of the depth cameras, and it may also put additional pressure on the connectivity of the systems.

Industrial 3D cameras need to combine sophisticated imaging modalities with robust housing, industrial-grade connectors and robust interface to provide a safe, reliable, and ruggedized 3D solution ideal for harsh environments.

Introduction to the Industrial Stereo Depth Cameras:
Advancing Vision in 3D

Unlike 2D cameras which capture flat images with only vertical and horizontal information, stereo 3D cameras provide an additional dimension, the depth data. This improves the spatial understanding of the scene and enables object distance measurement and shape details measurement. This additional depth data enables robotic technologies to perform complex operations such as navigation, manipulation, object recognition, and 3D mapping in industry, farming, traffic regulation, and many other fields. There are several popular and well-adopted 3D imaging technologies:
  • Time-of-Flight
  • Laser triangulation
  • Stereo Vision
  • Structured light

Each of them has its advantages and disadvantages. Stereo vision is practical, cost-effective, and works well in industrial settings. Stereo Depth cameras rely on stereo vision technology, mimicking human binocular vision. Two cameras set a few centimeters apart process images obtained through two slightly different positions.

The resulting offset is used as input for calculating the depth information by using triangulation.

To refine image quality and further improve performance, most stereo depth cameras employ active sensing and include a patterned light projector to help find corresponding points on otherwise flat or featureless surfaces.

Some depth cameras, like the Intel® RealSense™ camera, also include an RGB camera sensor in order to overlay color information on the resulting depth map.

Intel® RealSense™ Stereo Depth Cameras: Unraveling the Leading Edge of 3D Imaging Technology

The Intel® RealSense™ D435

Combining powerful hardware and sophisticated algorithms that capture and process depth information with unprecedented accuracy and precision, the Intel® RealSense™ cameras stand out as the leading stereo depth 3D technology.

RealSense™ cameras have found a place in many fields, such as robotics, augmented and virtual reality, autonomous driving, traffic, facial and gesture recognition, and industrial automation, to name only a few.

High-resolution imaging capabilities provide detailed depth and color data, crucial in applications such as 3D scanning, object recognition, autonomous driving, and precise measurements in manufacturing and medical fields.

User-friendly SDKs (Software Development Kits) and well-written and comprehensive documentation make their integration and implementation hassle-free.

Finally, Intel® RealSense™ cameras are cost-effective.

The Intel® RealSense™ cameras such as D415 and D435 however, are mainly aimed for consumer indoor applications and may not be well suited to industrial environments in their current version.

Stereo Depth Cameras Applications

RealSense™ D400 Stereo Vision technology is a well-recognized 3D imaging solution. It is used in various industrial environments, from smart agriculture to automotive manufacturing, as a part of different automated processes.

Here are a few interesting use cases from our clients.

Materials Handling

One of the most challenging problems in material handling involves robots working with heavy equipment and machinery, often in close proximity to human workers, which introduces severe risk and raises many safety concerns.

In warehouses, numerous industrial trucks and forklifts move rapidly back and forth between workers and pallets, bringing a great risk of collisions and dangers for humans. Another burden to the already complex situation is that drivers are often inexperienced and work under intense time pressure.

To improve warehouse safety, Xesol Industrial Vehicles developed Drivox® Security – a safety system for industrial vehicles that detects pedestrians and objects in the front and rear of the vehicle to prevent collisions.

The system is based on two FRAMOS industrial GigE depth cameras, D435e, fitted at the front and rear of the vehicle for three-dimensional perception, a microprocessor unit for AI-based image analysis, and a display serving as a monitor for the driver, intuitively showing him the calculation results.

Consistent and reliable real-time depth perception provides real-time inputs allowing vehicles to detect and avoid humans and other obstacles accurately.

This technology significantly reduced the risk of accidents in warehouses, ensuring safety for the people and efficient operations. Read the case study on this link.


Smart Agriculture

FRAMOS D400e cameras are used for three agricultural operations:

  • Plant growth and health monitoring
  • Navigating vehicles on the farm
  • Harvesting

When combined with 2D RGB or NIR imaging, depth data contributes to agriculture productivity and sustainability on multiple levels.

It helps reduce pesticide usage, improves guiding machinery while avoiding obstacles like plants, and allows automated picking machines to assess a fruit’s ripeness for efficient harvesting accurately.
