According to foreign media reports, a research team at the Karlsruhe Institute of Technology in Germany used inkjet printing technology to create a compact multi-spectral version of the light field camera.
The camera is only palm-sized and is suitable for many applications such as autonomous driving, recycled material classification and remote sensing.
, (Source: Karlsruhe Institute of Technology),3D spectral information can be used to classify objects and materials.
however, collecting 3D spatial and spectral information from scenes often requires multiple equipment or a time-consuming scanning process.
The new light-field camera solves this problem by simultaneously collecting 3D information and spectral data in a single snapshot.
Uli Lemmer, team leader, said: “This is an advanced highly integrated multi-spectral light field camera.
Researchers combined it with new artificial intelligence (AI) methods to reconstruct scene depth and spectral characteristics, creating an advanced sensor system that can be used to collect 3D information.
“, In the journal Optics Express, researchers report that this new camera and image reconstruction method can distinguish objects in a scene based on their spectral characteristics.
The use of inkjet printing to manufacture key optical components of the camera makes it easy to customize or produce in large quantities.
Researcher Michael Heizmann said: “3D data reconstructed from camera images is widely used in different fields, such as virtual and augmented reality, autonomous vehicles, robots, smart home devices, remote sensing and other fields.
For example, this new technology could allow robots to better interact with humans, or improve the accuracy of sorting and separation of materials during recycling.
This is also expected to be used to classify healthy and sick tissues.
