Abstract
The present invention discloses a vision-based aircraft landing aid. During landing, it acquires a sequence of raw runway images. The raw runway image is first corrected for the roll angle (γ). The altitude (A) can be calculated based on the runway width (W) and the properties related to both extended runway edges on the rotated (γ-rotated) runway images. Smart-phone is most suitable for vision-based landing aid.
Claims20
A vision-based landing aid apparatus for an aircraft, comprising:
- means for capturing at least a raw runway image;
- means for processing said raw runway image, said processing means being configured to extract properties related to extended runway edges from said runway image and calculate an altitude (A) of said aircraft based on the runway width (W) and the extracted runway-edge properties.
Dependencies are inferred from the claim text.
