Patent number: 11427218Abstract: A laser range finder projects light while changing a direction in a horizontal direction at a predetermined angle with respect to a vertical direction to also receive reflected light of the light, and detects a direction and a distance in which the light is reflected from an obstacle or the like, according to a difference time between a time of light projection and a time of light reception. A normal direction of a flat plane forming a road surface is detected on the basis of a polarized image. The laser range finder projects light such that the light has a predetermined angle with respect to the vertical direction so as to be orthogonal to the normal direction of the flat plane forming the road surface. The laser range finder can be applied to in-vehicle systems.Type: GrantFiled: July 25, 2018Date of Patent: August 30, 2022Assignee: SONY CORPORATIONInventors: Takuto Motoyama, Hideki Oyaizu, Yasuhiro Sutou, Toshio Yamazaki, Kentaro Doba

Patent number: 11328444Abstract: The present disclosure relates to a signal processing apparatus and system. In calibration, a sensor section is used to acquire a time of day when a stereo camera image capturing a target is acquired and a time of day when a radar image capturing the target is acquired. The target has a radar reflector and a marker. The image acquisition times of day are acquired while at the same time changing a distance between the sensor section and the target so as to find an amount of time-of-day discrepancy, a difference in time of day between the stereo camera image and the radar image at the same distance. At the time of object detection, the radar image acquired first is buffered and then output together with the stereo camera image acquired by the time-of-day discrepancy later, thus combining the stereo camera image and the radar image.Type: GrantFiled: August 8, 2018Date of Patent: May 10, 2022Assignee: SONY CORPORATIONInventors: Toshio Yamazaki, Takuto Motoyama, Kentaro Doba, Yasuhiro Sutou

Publication number: 20200357284Abstract: An object detection section detects an object that is present in surroundings. A transmission section broadcasts a request signal requesting information regarding an object that has not been detected by the object detection section. A reception section receives a response signal in response to transmission of the request signal, the response signal including the information regarding the object that has not been detected by the object detection section. For example, a display control section controls display of a surrounding environment on the basis of information regarding positions and attributes of a predetermined number of objects detected by the object detection section and controls update of the display of the surrounding environment on the basis of information regarding a position and an attribute of the object that is included in the response signal and that has not been detected by the object detection section.Type: ApplicationFiled: December 10, 2018Publication date: November 12, 2020Applicant: Sony CorporationInventors: Yasuhiro SUTOU, Toshio YAMAZAKI, Kentaro DOBA, Takuto MOTOYAMA, Seungha YANG
