Abstract
Provided is an altitude measurement apparatus and method that may measure an altitude of an aircraft without using a separate altimeter. The altitude measurement apparatus may include a camera unit being provided to a vertical takeoff and landing (VTOL) aircraft to collect an image of a circular mark formed on the ground, and a calculation unit to calculate an altitude of the VTOL aircraft based on the collected image. Accordingly, the altitude measurement apparatus may measure the altitude using a simple structure such as the circular mark formed on the ground, and be configured at inexpensive costs.
