3D Street Art has become more popular in recent years. Many 3D illusion artworks are shown on pavement such as streets, sidewalks, and town squares. It’s often known as 3D chalk art which a 2D artwork drawn on the street itself giving the viewer a 3D optical illusion from a certain perspective. This thesis presents an editing system to synthesis computer graphic models into a realistic photograph without requiring access to the scene to draw 3D street paintings on the ground. First the camera position was recovered using camera calibration algorithm. Second, a NPR stylization technique was applied to create artistic image of 3D models with the same camera position. Finally, the NPR image was composited into source photograph using Poisson approach. All enhanced pavement texture details were also blended on object image. With a small amount of specifications and adjustments, user can create a lively and interesting result which likes those realistic 3D art illusions.
