The process of projecting a predetermined pattern (typically grids or horizontal bars) onto a scene is known as structured light. The way these deform as they strike surfaces allows vision systems, such as those used in structured light 3D scanners, to determine the depth and surface information of the objects in the scene.
A succession of parallel black and white patterns are projected onto the scan target by the light source from the scan head. The patterns are distorted when light is projected onto the surface of the object. These photos are taken by the cameras, which then transmit them to the 3D scanning software for processing.
The z-depth of each illuminated camera pixel is determined using structured-light techniques using a projection device. By optically combining the projector ray that lighted the surface element with the camera beam, this is accomplished.
The Global Structured Light Camera market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
New Orbbec 3D cameras launch at CES for low-light and industrial applications. Orbbec debuted a series of new 3D cameras and a processor with advanced features capable of supporting biometric deployments in difficult conditions.
Orbbec is demonstrating four products at the virtual event, including its time-of-flight (TOF) sensor, which can scan moving objects with high accuracy and a depth-of-field range of 0.2 to 5 metres, 6-axis IMU motion tracking, full function in complete darkness, and support for multi-camera synchronisation.
Effective 3D imaging in low-light conditions could increase the use of facial recognition for applications such as outdoor access control.
Orbbec has also created an industrial-grade 3D camera with extremely high depth resolution and real-time 3D reconstruction. It is anticipated that the product will be offered as a white-label OEM product.
The Astra+, the most recent in Orbbec’s Astra range of structured light 3D cameras, features an RGB camera that has been upgraded from VGA to 1080-pixel resolution and greater thermal performance.
The Zora P1 processor board pairs with the company’s 3D cameras to give developers and hobbyists a method to combine 3D imaging and computing activities in a single solution.
According to the statement from Orbbec, the Zora P1 is an example of the company’s dedication to creating distinctive products that can be customised to meet the individual demands of consumers.
