Abstract: A method for fusion of radar and visual information, the method comprises: obtaining visual information and radar information about a three dimensional (3D) space located within a field of view of a camera that acquired the visual information and within a field of view of a radar that acquired the radar information; finding, based on the visual information, estimated visual-detection-based (VDB) objects and estimated VDB locations of the estimated VDB objects within the 3D space; wherein the estimated VDB locations exhibit a distance ambiguity; determining hybrid-detection-based (HDB) objects and HDB locations of the HDB objects, based on (i) the radar information, (ii) the estimated VDB objects, and (iii) the estimated VDB locations of the VDB objects.

Abstract: A method and system are provided for estimating tire tread depth, the method comprising: obtaining an image of the tire informative of tread and grooves embedded therein, wherein the image is acquired by an imaging device from a first angle relative to a horizontal direction perpendicular to tread surface, and the tire is illuminated by an illumination device from a second angle relative to the horizontal direction, causing a shadow section and an illuminated section at the bottom and/or sidewall of a groove, the first angle being smaller than the second angle, such that the image captures the illuminated section and at least part of the shadow section; performing segmentation on the image to obtain image segments corresponding to the illuminated section and the at least part of the shadow section; and estimating the tread depth based on the image segments, the groove width, and the second angle.

Abstract: A multi-spectral vehicular system for providing pre-collision alerts, comprising two pairs of stereoscopic infrared (IR) and visible light (VL) sensors, each of which providing acquired image streams from a mutual field of view, which are synchronized to provide stereoscopic vision; a data fusion module for mutually processing the data streams, to detect objects within the field of view and calculating distances to detected objects; a cellular based communication module for allowing communication between the sensors and mobile phones/Infotainment systems of the vehicle. The module runs a dedicated background application that is adapted to monitor the vicinity of the vehicle to detect other vehicles having a similar system; calculate speed and heading azimuth of each of the other vehicles; and provide alerts to the driver of the vehicle whenever other vehicles having a similar system are in a path of collision with the vehicle, based on the calculation and on the speed of the vehicle.
