In this paper, we want to construct a 3D space with panorama images without additional equipment. In other words, the panorama images taken by the user are input to the system proposed in this paper, and then the edge feature points of the image are extracted. In addition, we construct a 3D space using extracted feature points and construct a space by measuring relative distances between feature points by using Euler angle and 3D-TM algorithm. The conventional triangulation method does not know the height measured by the user since the result is two dimensional. In this paper, we tried to solve these problems by using 3D triangulation method. In order to evaluate the performance of the proposed panorama image-based 3D spatial composition system, the error rate of the proposed system was obtained by comparing the measured value with the measured value of the experimental environment. As a result of the performance evaluation, the system of this paper using the proposed algorithm has an error of less than 35cm and an error rate of 1.279%. Therefore, we expect the efficiency of the proposed system to be high.
