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.
