VR3D SuperCapture Re-Lighting and Face PBR material scanning modeling equipment
SuperCapture heavy lighting and face PBR material scanning modeling equipment (LightStage) developed specifically for game, film, and CG industry applications, can efficiently capture, process, and generate pore-level 3D models of human faces, and obtain physics-based rendering (PBR) materials and maps (Normal map, Diffuse Map, Roughness Map, Specular Map) directly through software algorithms.
- Integrated whole process design from structure, circuit, software to algorithm to ensure that the software and hardware debugging is guided from the final measurement results;
- Spherical light field simulation design, vertex machining integrated molding, error less than 0.1mm, to ensure accurate installation of the light field structure and accurate pointing of all light sources;
- light source parameters, structure parameters and camera parameters to ensure uniform and complete target lighting;
- The measurement system and the spherical light field system are decoupled in structure to avoid changes in camera array positional parameters caused by human shaking and other factors.
Generate high-resolution geometry, PBR mapping
We have developed hardware, software and a full set of algorithms with a complete solution by ourselves. Using 60-200 Canon SLR cameras with 24 million pixels with standard set lenses, shooting resolution better than 0.1mm, we can generate high-precision models with 2-30 million faces, and generate high-definition PBR mapping (Normal, Diffuse, Roughness, Specular, etc.) through photometric algorithms.
Integrated simulation and design from hardware to algorithm
Dedicated custom light source system design
- Light source system after several rounds of iterations, all using domestic electronic components;
- High peak power of the light source to ensure that image acquisition achieves large depth of field, low ISO and short exposure time;
- bus-based light source system design to achieve high synchronization and low latency;
- Can support hundreds of user-defined synchronous lighting codes, as well as unlimited non-synchronous codes.
- (a) The light source system, camera control system and data acquisition system use special circuitry and software to ensure seamless system connection;
- A bus design for the system, with synchronization errors up to the microsecond level;
- Supporting multiple types of cameras and large data volume acquisition and transmission;
- The system adopts modular design to ensure expandability.
Expandable design of electronic control system
Point-and-click software control
With the independent intellectual property rights of system software and hardware, it replaces the responsible program and command input with a clickable user interface. To do one-click shooting, remote control shooting, one-click automatic modeling.

Q: What are the uses and differences between these types of equipment?
A: BodyCapture system is mainly used for static, high-precision 3D reconstruction, and the device outputs high-precision obj geometry models as well as color mapping with uniform lighting.
PerformanceCapture system is mainly used for dynamic, high frame rate 4D scan reconstruction, the device can output high frame rate model dynamic sequences, after the subsequent process can output high detail animation drive data. The device can also be used for volumetric video capture.
The SuperCapture system is mainly used for static, ultra-high precision, model and material scan modeling with PBR material optical resolution. The device outputs ultra-high precision geometric models and PBR material mapping (Diffuse, Normal, Specular, Roughness, etc.). At the same time, the device can also collect OLAT data for LOOKDEV development, and Relighting heavy lighting research.
Super Dimension can provide full body devices covering the full body scanning range of the human body, and also head devices covering the range of the human head and face. We also provide solutions for the integration of these devices with each other.
Q: What are the advantages of the Super Dimension device?
A: Chaowei builds the whole series of equipment as complete and mature products, rather than the assembly of parts and system integration. Therefore, the core hardware, control system, software and algorithms of the equipment are all developed and completed by Chaowei independently, and the software, hardware and algorithms are highly integrated and integrated with each other, thus guaranteeing the stability, operability and high-quality modeling results of the overall system of the equipment.
In the production process, we insist on completing the production test of parts and components, the installation and interconnection of the whole machine and the strict factory test of the whole machine at our own site, and then packaged and shipped to the customer site according to the module, so as to ensure the fast and reliable installation at the site and the stable and controllable product quality as well as the best equipment data output effect.
At the same time, we have built a professional data processing and data production application team, which can provide technical training and technical support services for equipment generation data processing and application.
Q: How do I order equipment? What is the delivery process like?
A: We provide several standard models of equipment for customers to choose, at the same time, you can contact us by phone to provide specific technical requirements and application needs description, by our professional team to provide you with suitable equipment configuration suggestions.
After both parties sign the contract, we will complete the production test of the equipment components and the installation and commissioning of the whole equipment at our own site, and after passing the strict factory test, we will contact you to determine the specific delivery and on-site installation and commissioning schedule. We provide on-site installation and commissioning of the whole system, and provide professional training services on equipment use and data processing, as well as professional and responsive after-sales support.
Q: What are the space requirements for the site when installing the equipment?
A: General head equipment needs 3m*3m to 4m*4.5m equipment installation and operation space, the whole body equipment needs 5m*5m to 6m*7m equipment installation and operation space, different equipment has different environmental layout requirements, we will provide the complete equipment environmental layout requirements document for your reference to prepare the site.
Q: What is the lead time for the delivery of the equipment?
A: Depending on different equipment configurations, the normal equipment production delivery lead time is 30~50 working days.
Q: Can the equipment be customized?
A: We can provide customized supply of equipment according to your special requirements, such as special scanning objects (animals, insect specimens, plants and other special applications) and application scenarios (vehicle-mounted, removable stands, etc.).
