Toshiba Corp developed a new series of its image recognition chips for driving support systems and announced its functions, etc at a press conference of electronica 2014.
The company defines the series, "TMPV760," as its fourth-generation product.
Pedestrian detection at night
Compared with Toshiba's previous products, the TMPV760 has two new major characteristics. It can detect pedestrians during nighttime hours and roughly obtain distance information only with one automotive camera to realize 3D recognition.
In 2018, the European New Car Assessment Programme (Euro NCAP) will start to require the capability to detect pedestrians during both daytime and nighttime hours. And the new product was designed to deal with it. Toshiba aims to start volume production of the series in December 2016.
Toshiba enabled to detect pedestrians at night by making improvements to an image recognition technology called "CoHOG." It can recognize the boundary between a pedestrian and the environment even at night by extracting five kinds of data such as the gradation of the color of the pedestrian and the texture of the pedestrian from video of the pedestrian and using the data.
Compared with the company's existing automotive image recognition chip, the new product's capability to detect pedestrians at night was improved by about 100%, the company said.
