Drawing and Landscape Simulation for Japanese Garden by Using Terrestrial Laser Scanner

Abstract

Commission V/WG 4 KEY WORDS: terrestrial laser survey, drawing of ground plan, landscape simulation, extract contour lines ABSTRACT:Recently, many laser scanners are applied for various measurement fields. This paper investigates that it was useful to use the terrestrial laser scanner in the field of landscape architecture and examined a usage in Japanese garden. As for the use of 3D point cloud data in the Japanese garden, it is the visual use such as the animations. Therefore, some applications of the 3D point cloud data was investigated that are as follows. Firstly, ortho image of the Japanese garden could be outputted for the 3D point cloud data. Secondly, contour lines of the Japanese garden also could be extracted, and drawing was became possible. Consequently, drawing of Japanese garden was realized more efficiency due to achievement of laborsaving. Moreover, operation of the measurement and drawing could be performed without technical skills, and any observers can be operated. Furthermore, 3D point cloud data could be edited, and some landscape simulations that extraction and placement of tree or some objects were became possible. As a result, it can be said that the terrestrial laser scanner will be applied in landscape architecture field more widely. * Corresponding author.

Assessing the Quality of the Leica BLK2GO Mobile Laser Scanner versus the Focus 3D S120 Static Terrestrial Laser Scanner for a Preliminary Study of Garden Digital Surveying

“…There is some research that already uses the static terrestrial laser scanning (TLS) method to register plants in historic gardens [16]; studies that evaluate the applicability of mobile laser scanning (MLS) in gardens [17][18][19] for the comparison of algorithms that extract tree information from the point cloud; and works that present the combination of laser scanning with digital photographs for the 3D digitization of these spaces [10,14,[19][20][21]. This scientific production, which has been developing and improving since mid-2010, points to a promising path in which there is still information to seek and knowledge to produce.…”

“…Diverse studies, in terms of tools and methods, have been undertaken in recent years on both forest surveying and historic garden surveying [4,5,16,17,[19][20][21]25,26]. In recent decades, the fields of cultural heritage and environmental sciences have seen their relations with digital technologies grow, including the use of sophisticated equipment to achieve more accurate field survey information.…”
