Abstract:

In recent years, increasing attention has been paid to indoor positioning. This paper presents a BIM-based Indoor positioning technology using a monocular camera. This technology utilizes a monocular camera to obtain on-site image. An improved corner detection algorithm is used to identify the corners of the ground tile in the on-site image. Combining the geometric information from BIM, this paper completes the conversion of image pixel coordinates to the actual coordinates of the indoor ground. Based on the location information of camera in BIM model, this paper achieves the precise positioning of actual indoor target in BIM model.
