Point Cloud Body Construction Based On Image

Much a subject of concern based on the image of the human body modelreconstruction computer vision, computer graphics, image processing, and the field ofergonomics. Its purpose is extracted from the two-dimensional plane of the image andthe information necessary to generate three-dimensional human body model by somealgorithm, and having a photo-realistic three-dimensional rendering.For creating and rendering parts of the human body model to do a more in-depththeoretical research and practice, especially in the rendering part is the core task. Firstintroduces the basic concepts of the theory of the three-dimensional reconstruction ofthe camera model, coordinate transformation, camera calibration methods. Andimage-based, according to the general steps, such as generating visual hull, thesmooth surface of the model, we have created a model of the human body. Finally, byway of graphics, using the OpenGL library to extract human model to the color valuesin the image on the projection position, and then the color information is attached tothe human body model, combined with the camera parameters and render itscalculation to generate the final contain3D human model with color information.
