Patent number: 10247551Abstract: Provided is an image processing device capable of maintaining recognition accuracy for distance, and the like, while meeting conflicting demands such as suppressing the response delay from image input from a camera to calculation result output, enhancing recognition accuracy, reducing calculation load (enhancing processing efficiency), and enhancing response speed. The time of the starting of the processing (S105) of a first distance calculation unit (105) for calculating the relative distance to an object on the basis of current position information determined on the basis of a left or right image and past position information for the object is set to an earlier time than the ending of the processing (S107) of an object detection unit (107) for determining current position information for an object on the basis of parallax information obtained from the left and right images and detecting the object.Type: GrantFiled: August 17, 2015Date of Patent: April 2, 2019Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Hideaki Kido, Haruki Matono, Takeshi Nagasaki, Shinji Kakegawa

Patent number: 10140526Abstract: The purpose of the present invention is to provide an object detecting device which is capable of accurately detecting an object even far away, and of shortening processing time. Provided is an object detecting device (100), comprising: a disparity acquisition unit (116) which compares each image of two cameras (112, 113) and computes a disparity for each pixel; a near-far boundary setting unit (118) which, in a single image of one of the two cameras, sets a boundary (Rb) between a near region (R1) which is close to a vehicle (110) and a far region (R2) which is distant from the vehicle (110); a near object detecting unit (119) which detects objects (102, 104) of the near region (R1) on the basis of the disparity; and a far object detecting unit (120) which detects objects (103, 104) of the far region (R2) on the basis of the single image.Type: GrantFiled: August 3, 2015Date of Patent: November 27, 2018Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Shinji Kakegawa, Takeshi Shima, Yuji Otsuka

Publication number: 20170300764Abstract: Provided are a travel route recognition device and a travel assistance system using the same, which are capable of precisely recognizing the positions of white lines and road boundaries even if, for example, there is a decrease in the accuracy of the detection of both white lines and road boundaries on the travel route. The direction of the travel route is estimated on the basis of the direction of a linear site included in an image obtained by imaging units, and the direction of the boundaries of a surface region included in a distance image comprising three-dimensional distance information generated on the basis of the images obtained by the imaging units or on the basis of distance information detected by the distance detection unit.Type: ApplicationFiled: December 16, 2015Publication date: October 19, 2017Inventors: Shinji KAKEGAWA, Takashi TSUTSUI, Haruki MATONO, Masayuki TAKEMURA, Takeshi SHIMA
