A camera monitoring system for a vehicle includes a plurality of cameras disposed around an exterior of a vehicle. An image processing module communicates with the plurality of cameras, generating overhead view images from raw images taken by at least one of the plurality of cameras. A histogram module communicates with the image processing module, generating at least one histogram from the overhead view images. A likelihood module communicates with the histogram module and determines a likelihood of blockage for at least one of the plurality of cameras. A line alignment module communicates with the likelihood module and the image processing module to determine whether a trajectory of detected feature points in a selected camera aligns with a trajectory of detected feature points in an adjacent camera. A reporting module communicates with the line alignment module and reports a camera blockage status to at least one vehicle system or controller.
