The Rebl Industries – Depalletizing with Photoneo demo showcases an advanced depalletizing solution designed for real-life production environments.
Utilizing Photoneo’s PhoXi 3D Scanner and AI-driven picking, the system performs fast and precise localization, handling up to 1300 packages per hour depending on size and weight. This collision-free operation is perfect for high-throughput scenarios, ensuring optimal speed and precision. Rebl Industries’ scalable robot-as-a-service model allows for seamless adaptation to various intralogistics needs, demonstrated by its continuous operation in real-world use cases like the “Clipson” system in Sweden.
Challenges and Importance
Depalletizing is a labor-intensive process with poses risks such as repetitive strain injuries and operational inefficiencies. This demo highlights how automation can lessen these challenges. Fast localization, powered by Photoneo’s advanced 3D vision, ensures accurate object detection, while AI optimizes the picking sequence. The solution also demonstrates scalability and quick deployment, with minimal commissioning time on site. By replacing manual labor with automated systems, industries benefit from increased productivity, reduced labor costs, and enhanced workplace safety.
Demo: Bin Picking
Products:
- Bin Pickin Studio 1.9
- PhoXi 3D Scanner S
- 2 x PhoXi 3D Scanner M
- MotionCam-3D Color S
Demo Description:
This demo showcases an advanced robotic pick-and-place system handling unstable parts from a central bin. The robot uses three scanning modes—Static MultiView, Hand-Eye MultiView, and Regular Hand-Eye—to locate, pick, and precisely position the parts onto fixtures on a moving conveyor belt. The parts, that can bend and shift unpredictably, require precise localization and handling. The system performs multiple picks, regrips at a centering station, and finally places the parts back into the bin after fixture processing.
Challenges Overcome:
The complexity lies in managing several difficult tasks simultaneously on one Vision Controller. Most notably, the “Pick Check to Magnet Drop” requires the system to accurately calculate transformations based on the hinge’s position on the gripper to ensure correct re-gripping on magnets. Normally, these challenges are seen individually in production, but this demo integrates them all at once. Handling an unstable part, precise placement on a conveyor belt, and automated regripping demonstrate the system’s ability to solve multiple real-world challenges with high accuracy and reliability.
What is Multiview?
The MultiView module enables scanning from multiple sensors or viewpoints, effectively avoiding occlusions and ensuring robust localization and collision avoidance. In MultiView scenarios, “Multiple static sensors” involves one primary sensor calibrated with the robot and secondary sensors calibrated to the primary, scanning sequentially, while “Hand-eye” uses a Photoneo 3D Sensor on a robotic arm for unlimited static or dynamic scans from various viewpoints.
- Complex Shapes and Challenging materials: Ideal for thin, C or L-shaped metal sheets, bins with compartments, and thin or highly reflective objects that are difficult to capture from a single perspective.
- Essential Feature Visibility: Ensures precise localization by revealing the essential model features that might be obscured in a single view.
- Self-Occluding Objects: Overcomes the challenges posed by self-occluding objects.
- Large Objects: Handles large objects which would not fit the FOV of a single scan.
- Higher Detail Quality: Achieved by using a sensor with lower point-to-point distance and scanning volume and capturing the scene multiple times
Demo: 3D Scanning of Transparent Objects
Products:
MotionCam-3D Color (Red), MotionCam-3D Color (Blue)
Demo Description:
In this demo, the MotionCam-3D Color scans a scene containing transparent, semi-transparent, and translucent objects—materials traditionally difficult to capture using structured light. The demonstration showcases how the MotionCam-3D Color, equipped with the proprietary COMPIS sensor, accurately reconstructs these challenging objects in 3D, displaying their shape and color with great detail.
Technical Challenges:
Scanning transparent and semi-transparent objects with structured light is notoriously difficult due to the refraction and blending of foreground and background signals. To overcome this fact, we introduced a new laser projection mode that uses sparse, proprietary laser patterns.
This innovation allows us to differentiate the signals, prioritizing the information from the foreground object regardless of its transparency and successfully capturing its 3D structure. The mentioned advancement in laser projection and signal processing was the key to overcoming the challenges posed by these materials.
Sparse projection is a game changer for transparent scanning on static objects. Our new blue laser technology enhances scanning performance on transparent objects even further, thanks to the unique scattering properties of blue light.
Demo 2 – Digital Twinning of Objects in Motion with Red and Blue MotionCam-3D

Photoneo 3D Meshing – 3D Instant Meshing library
Demo Description:
This demo showcases how two MotionCam-3D Color devices, each using a different wavelength (red and blue), capture the same scene simultaneously without any interference or distortion. An object, mounted on a Techman robot, is moved within the cameras’ field of view.
The high framerate of the cameras—up to 20 fps in grayscale and 12 fps with color—enables precise scanning from multiple angles. This data is then processed in the 3D Instant Meshing application, which stitches the scans together to create a real-time, high-detail 3D model of the moving object.
Technical Challenges:
Simultaneous scanning with multiple devices typically leads to interference, where the projected light patterns overlap and distort the resulting point clouds. By employing two different wavelengths for the projection units, we overcome this issue, allowing the red and blue laser light to work in harmony without mutual distortion.
The MotionCam-3D Color’s capability to capture high-resolution data at up to 20 fps ensures that the object is scanned from various angles quickly and accurately. The 3D Instant Meshin application leverages both 3D and 2D features to seamlessly stitch the scans together, allowing for automatic, real-time model creation without the need for a global coordinate system. This combination of precision, speed, and sophisticated software integration represents a significant advancement in digital twinning technology.
