When multiple image sensors take a picture of a specific object, each from a different angle, the object can be reconstructed in three dimensions from those images by using ingenious software. This technology is called ‘multiview imaging’. The simplest form of multiview imaging involves two image sensors. We call this stereovision. Imec has conducted research into multiview imaging for many years, after which the imec.engineering team took the technology out of the lab and beyond the research stage and made it market ready. Imec’s multiview imaging systems offer major advantages, such as speed, precision and low costs. These properties make them attractive for use in industrial applications, such as in robot vision or quality control. Peter Lemmens, General Manager of imec Taiwan, describes the marketing process and explains about the services that imec offers companies.
The possibilities of multiview imaging
Cameras that use stereovision are based on the capabilities of human eyesight. Two image sensors take a picture of a specific object from various positions and angles. Algorithms compare the images and go looking for corresponding pixels. A depth map is then generated using software in which the pixels are displayed according to their mutual distance from the camera. This data is used to display the object in 3D, visualizing it in what is called a ‘point cloud’. The camera performs with greater precision when more than two image sensors are used. This is called ‘multiview imaging’.
