Study on the Surveying Methods Based upon the 3D Laser Scanning and Close-range Photogrammetry Techniques of the Rockery and Pond in the Classical Chinese Gardens

As the main part of a classical Chinese garden, the rockery and pond's profile could hardly been accurately measured and clearly expressed. This paper takes the rockery of Huanxiu Villa and Couples retreat Garden as example to discuss the new measuring methods such as 3D laser scanning and closerange photogrammetry's feasibility in surveying works all around the classical gardens, hence makes a comparison between the traditional manual methods and intelligentized methods mentioned above, which draws a conclusion that the latter has a thorough advantage. It also discusses on the operational approach of information acquisition and drawing expression based upon such techniques. Eventually, the paper points out the applicability of the new surveying techniques in data acquisition and academic research.
