Abstract
A 3D model is used for an expression of product model and object recognition besides the simulation. The applied field is wide, and the importance is very high. However, an extensive cost is still needed for the creation of 3D model. Therefore, there are various researches on generating the 3D model quickly, easily, and at a low cost. The general technique has not been established. Then, in this research, we try to establish the technique of automatic creation of the 3D model by the photogrammetry from a digital animation filmed by digital video camera to satisfy the above-mentioned needs. Especially, we aim to solve the problem of the previous research. That is to improve the accuracy and speed for tracking feature points on an object for 3D modeling by the optical flow. Concretely, there are two subjects to decrease the processing speed and to improve the accuracy of movement and rotation in template matching method. We solved them using the optical flow by the Harris operator.
