Based on an established relationship between the displacement of the camera movement along the photographing direction and the difference in pixel counts between reference points in the images, photographing distance between the camera and an object on the oblique target plane can be calculated via the proposed method.distance measurementpixelsoblique planeincline angledigital camerasCCD imagesimage-based measuring systems
