摘要：In Japan, e-Japan Strategy II, which was announced in 2003, has been promoting the digital archives of tangible and intangible cultural heritage [1]. This effort is being continued in the i-Japan Strategy 2015 which was published in 2009 [2]. In addition, in a dangerous area such as a disaster area is in need of detailed data for lifesavings and reconstruction activities. In fact, three-dimensional scan at the affected areas has been carried out in order to check out of the damage in the Great East Japan Earthquake which occurred in 2011. However, three-dimensional object are often fragile, such as a disaster area and ruins with a complex structure. Therefore, observer must carry a scanner close to the object, the conventional three-dimensional system had a safety concerns. In this study we developed a scanning system of three-dimensional coordinate using quadcopter that allows flexible motion. The three-dimensional coordinate are reconstructed by the factorization method to the feature points witch are detected and tracking on the image sequence obtained from quadcopter. The feature point tracking experiments were performed using matching method and PryLK method. In the factorization method, two camera models are assumed, parallel projection and weak perspective projection. By scanning the cube of four types, we verified the effectiveness of the proposed method. Each cube has a different surfaces; solid color background, checkerboard, photos and random images. As a result, the coordinate reconstruction was effective in combination with PryLK method and weak perspective projection camera model
