Texture mapping based on photogrammetric reconstruction of the coded markers.

ABSTRACT

Texture mapping is one of the key procedures to generate photorealistic three-dimensional (3D) models. To avoid dependence on the features of the texture and the geometric model, coded markers are introduced as the control points to assist the texture mapping. Multiple texture images containing the markers are captured, and the 3D coordinates of the markers are reconstructed with photogrammetry; meanwhile, the parameters of the texture camera are optimized with the bundle adjustment strategy. Then the pose parameters of the texture mapping can be calculated with the assistance of the marker registration and the iterative closest point (ICP) algorithms. The validity of the proposed algorithm is demonstrated with an experiment on an ordinary object.
