  • Publication number: 20240054656
    Abstract: [Object] To detect an installation error of an imaging device by simple processing. [Solving Means] A signal processing device of the present disclosure includes an optical flow detecting unit configured to detect an optical flow on the basis of an image captured by an imaging device installed on a vehicle, and an installation error calculating unit configured to calculate an amount of error in attitude of the imaging device on the basis of information on the optical flow.

  • Patent number: 11836945
    Abstract: An accurate subject distance can be calculated on the basis of a camera captured image even in a case where the attachment angle of a camera is deviated. An image captured with a camera having a wide-angle lens is input to perform distortion correction and generate a corrected image. Moreover, the inclination of a vertical object in the real world in the corrected image is calculated. The deviation angle of the camera depression angle of the camera is calculated on the basis of the inclination of the vertical object. An object distance calculation image is generated in consideration of the camera depression angle deviation angle. The distance of an object included in the camera captured image is calculated from the object distance calculation image.

  • Patent number: 8346071
    Abstract: A camera system includes a detection unit that detects fitting errors of a camera as displacement quantities in a first direction, a second direction and an optical axis rotating direction of an image picked up by the camera, a selection unit that selects a rotation correcting quantity corresponding to the displacement quantity in the optical axis rotating direction from plural rotation correction maps prepared in advance, a computation unit that computes the correcting quantities in the first direction and the second direction respectively based on the detected displacement quantities in the first direction and the second direction using linear equations; and a correction unit that corrects the displacements in the first direction, the second direction and the optical axis rotating direction of the picked up image based on the selected rotation correcting quantity and the computed correcting quantities in the first direction and the second direction.
