Abstract: Now outdoor augmented reality technology mostly uses the registration method by hardware trackors for exploration and exhibition problems. In order to meet the application requirements in outdoor planning and design, registration method based on computer vision could be used which is more interactive. Coordinates of calibration points, which is essential to vision registration, can be calculated using computer vision method assisted by range finder, so it can be applied in image-based outdoor planning and design. The registration process can be simplified by setting camera coordinate system to coincide with world coordinate system. Outdoor planning and design will benefit from all of these works.

Key words: computer application, outdoor augmented reality, computer vision, coordinates of calibration points, planning and design
