Abstract
Disclosed is a method for determining valley areas accessible by an aircraft, the method being implemented by an electronic device, the method including the following steps: obtaining an initial image of an environment including areas of valleys; processing the initial image so as to eliminate the imaged elements on the initial image, the dimension of the elements being less than a predetermined dimension, to obtain a first processed image; and determining the curvature of each imaged element in the first processed image, the valley areas accessible by the aircraft being the imaged elements, in the first processed image, the curvature of which is strictly less than zero.
Claims21
A method for determining valley areas accessible by an aircraft, the method being implemented by an electronic device, the method comprising:
- a. obtaining an initial image of an environment comprising valley areas,
- b. processing of the initial image so as to eliminate imaged elements on the initial image, dimensions of which are smaller than a predetermined dimension, to obtain a first processed image, said processing comprising:
- i. reducing resolution of the initial image so as to remove those imaged elements on the initial image whose dimension is less than the predetermined dimension, and
- ii. applying a Gaussian blur filter to the resulting reduced resolution image so as to obtain the first processed image, and
- c. determining a curvature of remaining imaged elements in the first processed image, the valley areas accessible by the aircraft being the remaining imaged elements, in the first processed image, the curvatures of which are strictly less than zero.
