Patent number: 8144195Abstract: A vehicle zone monitoring apparatus that detects physical bodies present in the vicinity of the vehicle from infrared images photographed by infrared cameras provided on the vehicle includes an object extracting device that extracts object images that emit infrared radiation from the infrared image and an artificial structure identifying device that identifies whether or not an object is an artificial structure by comparing an image of a search zone in proximity to the object extracted by the object extraction device, to a reference image of a pre-registered artificial structure which serves as an element that defines an artificial structure, and that identifies the object as an artificial structure if: within the search zone in proximity to the object, a section having a high correlation with the reference image exists; and a distance between the vehicle and the object is equal to a distance between the vehicle and the section having the high correlation with said reference image.Type: GrantFiled: October 9, 2008Date of Patent: March 27, 2012Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Nobuharu Nagaoka, Takayuki Tsuji, Masahito Watanabe, Hiroshi Hattori, Kouzou Simamura

Patent number: 7474765Abstract: An image processing unit determines the size of a circumscribed quadrangle of the target object, and predicts the overlap of the two different objects. If overlap is predicted, the target object is divided into two divided regions L_b and R_b containing the left and right edges of the target object respectively, and by performing a correlation calculation between the left image and the right image captured by a stereo camera for each of the divided regions, the parallaxes of the respective divided regions L_b and R_b can be determined. Then, if the absolute value of the difference between the parallaxes of the respective divided regions L_b and R_b is greater than a predetermined value, a determination is made that different objects are overlapping within the target object, and the target object is divided for recognition, and the distance to the respective objects is calculated independently.Type: GrantFiled: October 30, 2006Date of Patent: January 6, 2009Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Nobuharu Nagaoka, Takayuki Tsuji, Hiroshi Hattori, Kouzou Simamura, Masahito Watanabe

Publication number: 20030007074Abstract: The present invention provides a vehicle zone monitoring apparatus that eliminates artificial structures based on shape identification using a reference image from an infrared image photographed by a photographing device provided in the vehicle, and detects remaining objects as physical bodies that move, such as pedestrians and animals. The vehicle zone monitoring apparatus that detects the physical bodies present in the vicinity of the vehicle from infrared images photographed by infrared cameras 2R and 2L provided on the vehicle comprises an object extracting device that extracts object images that emit infrared radiation from the infrared image and an artificial structure identifying device that identifies whether or not an object is an artificial structure by comparing the object image extracted by the object image extracting device to a reference image that comprises a straight line pattern or a right angle pattern.Type: ApplicationFiled: June 12, 2002Publication date: January 9, 2003Applicant: Honda Giken Kogyo Kabushiki KaishaInventors: Nobuharu Nagaoka, Takayuki Tsuji, Masahito Watanabe, Hiroshi Hattori, Kouzou Simamura
