Abstract:
1. An image recognition system which recognizes a subject, which is moving with respect to an image capturing unit provided in a vehicle, included in an image captured by the image capturing unit, comprising: the image capturing unit; a first recognition unit which recognizes a candidate of the subject included in the image captured by said image capturing unit by comparing the image captured by said image capturing unit with predetermined template data; a template selection unit which selects the template data to be compared with an image captured by said image capturing unit after a predetermined duration has been elapsed from a time of capturing an image used for recognition of the candidate by said first recognition unit; a second recognition unit which recognizes the subject by comparing the image, which is captured by said image capturing unit after a predetermined duration has been elapsed from a time of capturing an image used for recognition of the candidate by said first recognition unit, with the template data selected by said template selection unit; a speed measurement unit which measures speed of the vehicle; and a region estimate unit which estimates a position of a region indicating the subject in an image captured by said image capturing unit after a predetermined duration has been elapsed after a time of capturing an image used for recognition of the candidate by said first recognition unit based on a region indicating the subject recognized by said first recognition unit in an image captured by said image capturing unit, and on the speed, wherein said second recognition unit recognizes the subject by comparing a predetermined range of image centering on a position estimated by said region estimate unit among images captured by said image capturing unit with the template data selected by said template selection unit; and further comprising a steering angle measurement section which measures a steering angle of the vehicle, wherein said region estimate section estimates a position of a region indicating the subject further based on the steering angle.
