Embodiment Construction

[0081] Referring now to the drawings, in which certain exemplary embodiments are shown for illustration only and not for limitation, figure 1 An exemplary vehicle 5 is shown equipped with at least one camera and display system 145 according to the present disclosure. The at least one camera device may include a rear camera device 102 proximate to the rear end of the vehicle 5 and configured to obtain rearward images having a perspective behind the vehicle. For example, the rear camera 102 may be a wide field of view (FOV) camera positioned proximate to the vehicle's rear license plate. The at least one camera may also include a front camera 104 configured to obtain a forward image having a perspective in front of the vehicle. The at least one camera device may also include at least one side view camera device 103 configured to obtain side view images having a perspective of one or both sides of the vehicle. Accordingly, the camera may include one or more of the rear camera ...

Abstract

The invention relates to a dynamic guideline overlay with image cropping. A method for dynamically registering a graphic upon a cropped image obtained from a camera device includes capturing an original image obtained from the camera device. Intrinsic calibration information for the camera device, extrinsic information for the camera device and vehicle information are monitored. The cropped image is generated based on cropping parameters to exclude undesirable content from the original image. The intrinsic calibration information is adjusted based on a relationship to the cropping parameters. The graphic is dynamically registered upon the cropped image based on the adjusted intrinsic calibration information for the camera device, the monitored extrinsic information for the camera device and the monitored vehicle information.

Description

technical field [0001] The present disclosure relates to vehicle vision systems. Background technique [0002] The statements in this section merely provide background information related to the present disclosure. Accordingly, such statements are not intended to constitute an admission of prior art. [0003] Modern vehicles may include one or more camera devices that provide, for example, reverse assist, images of the road representing road conditions and maneuvers while the vehicle is in motion, and images showing signage along or near the road. For applications where graphics are superimposed on camera images, it is important to accurately calibrate the focal length parameters and optical center parameters for the camera device. Cropping the camera image may result in an inaccurate superimposed camera image if intrinsic calibration information such as focal length parameters and optical center parameters are not accurately calibrated or adjusted. [0004] For example, ...
