Sensory & Photonic Vision Systems
Image handling is instrumental in many applications, including consumer electronics, surveillance, robotics, machine vision, etc. Some of them demand high quality images, while others require fast analysis and interpretation of the image flow. Despite the specific target, all applications benefit from embedding processing circuitry together with optical sensors in the same silicon substrate. CMOS technologies allow the incorporation of digital processing on-chip to correct image artifacts or to analyze and interpret the scene in real-time. Using CMOS technologies enables the implementation of cameras and vision systems with reduced power consumption and reduced size. This permits the incorporation of vision in applications where it was previously considered to be economically prohibitive or technically unfeasible.
This research line embraces different activities related to the incorporation of intelligence into image sensors, namely:
Different application areas are covered like automotive, unmanned vehicle navigation, distributed smart cameras and vision-enabled wireless sensor networks. These applications have been benchmarked by using real systems. Significant parts of the technology have been transferred to industry, including the creation of spin-off companies.
