Abstract
The ratio is calculated between a first number of pixels and a second number of pixels on an image sensor. The first number of pixels is counted between two certain points projected on the image sensor from a first section of a plane. The second number of pixels is counted between two certain points projected on the image sensor from a second section, adjacent to the first section, of the plane. The number of pixels between two certain points increases if the image sensor gets closer to the plane, while the number of pixels between two certain points decreases if the image sensor gets remoter from the plane. The inclination of the image sensor can be determined relative to the plane based on the ratio between the two numbers of pixels. The attitude or inclination of the image sensor can in this manner be detected with a high accuracy.
