US Scientists develop New Imaging Technology capable of working in Bright Sunlight

A team of American researchers led by an Indian-origin robotics scientist has recently developed a new imaging technology that can even work in Bright sunlight. As per its makers, the technology successfully addresses the major shortcoming of depth-sensing 3D cameras.

It has been said that the researchers from Carnegie Mellon University and the University of Toronto created a mathematical model to help programme these devices.

These devices allow the camera and its light source to work together efficiently, by eliminating extraneous light, or noise, which usually wash out the signals required to detect a scene’s contours.

Srinivasa Narasimhan, Carnegie Mellon University associate professor of robotics, said in a statement that they have a way of choosing the light rays which they want to capture and only those rays.

“We don't need new image-processing algorithms and we don't need extra processing to eliminate the noise, because we don't collect the noise. This is all done by the sensor”, said Narasimhan.

One prototype based on this model synchronizes a laser projector with a common rolling-shutter camera so that the camera detects light only from points being illuminated by the laser as it scans across the scene.

This combination would allow using the imaging technology for many applications in field like medical imaging, inspection of shiny parts and sensing for robots used to explore the moon and planets. It can also be incorporated into smartphones, said researchers.

The researchers presented their findings at SIGGRAPH 2015, the International Conference on Computer Graphics and Interactive Techniques, in Los Angeles.
