Abstract
Provided is a method of selecting a two dimension (2D) image for three dimension (3D) reconstruction, the method including: receiving, by an image processing apparatus, 2D images captured at different positions or in different directions; estimating, by the image processing apparatus, a geometric structure of a camera based on feature points detected from the 2D images, and optimizing the geometric structure of the camera using a bundle adjustment (BA) technique; determining, by the image processing apparatus, a priority for each of the 2D images based on a number of tie points used in the BA process; and selecting, by the image processing apparatus, final 2D images to be used for 3D reconstruction based on the priorities of the 2D images.
