14 Claims

1. A method for acquiring a set of images of a target area using an aerial vehicle for 2D/3D digital model reconstruction for a target area of interest using a single camera, said method comprising:

moving the aerial vehicle over the target area of interest along a straight path;

capturing, while the aerial vehicle is moving over the target area of interest, a first set of images of an area down below by pointing an optical axis of the camera towards a first side of the straight path such that the optical axis makes a first predefined angle with respect to a vertically downward direction of the aerial vehicle;

capturing, while the aerial vehicle is moving over the target area of interest, a second set of images of the area down below by pointing the optical axis of the camera towards a second side of the straight path such that the optical axis makes a second predefined angle with respect to the vertically downward direction,

wherein the optical axis of the camera is perpendicular to a direction of motion of the aerial vehicle, and

wherein the first set of images and the second set of images captured during the movement of the aerial vehicle along the straight path include a side overlap; and

adjusting, using a ground controller, a percentage of the side overlap between adjacent first set of images and second set of images captured during movement of the aerial vehicle along any two of adjacent straight paths and a side overlap between the first set of images and the second set of images captured during movement of the aerial vehicle along any of the straight paths.
