Claim Text:
1. A stereo image processing device for a vehicle that processes images captured by a stereo camera unit installed on the vehicle and three-dimensionally recognizes a traveling environment, the device comprising: a left-right similar object detection module that detects a left side object present along a road and right side object which is present along the road and is similar to the left side object present as a pair on the left and right side of the vehicle from an image captured by the stereo camera unit, performs matching processing of the left side object and the right side object, and calculates a parallax of the left side object and a parallax of the right side object on a same horizontal line of the image; and a camera displacement diagnosis module that calculates a diagnostic value based on a difference between the parallax of the left side object and the parallax of the right side object on the same horizontal line, compares the diagnostic value with a preset threshold value, and diagnoses a vertical mechanical displacement in the stereo camera unit.
