| Abstract: | During the integrated ceiling construction work located in the lower boom of ultra-large hyperboloid net brace for Beijing Capital International Airport T3B, a new close-range photogrammetry technology is adopted to measure the 3D coordinate for the lower boom ball of net brace. We just need put a few controlling spots and take some photos on the site. The advantages such as short measure time and big information collection of new technology are took into fullplay. This kind of new technology help us to save a lot of time during the measurement. |
