Abstract
A driving assistance system that projects images imaged by multiple vehicle cameras onto a plane, and synthesizes projection images from images obtained at different times to accurately determine whether the vehicle cameras have moved out of their proper positions or imaging directions. The system includes: first and second in-vehicle cameras that capture first and second images, respectively. The cameras capture overlapping regions respectively in different directions. An image converter converts the first and second images into first and second projection images projected onto a plane. A solid object detection unit determines whether a solid object exists in the overlapping region. When no solid object exists, the images of the overlapping regions within the first and second projection images are compared to generate a comparison value. The comparison value is in turn compared with a threshold value for the determination of vehicle camera movement out of its proper position.
