Even if the potentialities of the image-based 3D reconstruction approach are nowadays very well-known in terms of reliability, accuracy and flexibility, there is
In the W¨urzburg Residence an iSpace sensor frame is also mounted on top of the laser scanner.. iSpace is a high-precision position and tracking system from Nikon

Afterwards, local smoothness constraint and point cloud segments are utilized to improve the disparity image that are derived from the semi-global dense image
Beside the direct georeferencing, also the precise time synchronization of the camera, which acts as the main sensor for mobile mapping applications, and the calibration of the
The PIQuAT (Portable Imagery Quality Assessment Test Field) field had been designed especially for the purposes of determining the quality parameters of UAV sensors, especially in
Therefore, this paper proposes the method to generate the IndoorGML data semi-automatically, especially based on the omni-directional image which is the most
After improving the initial values of interior and exterior parameters at first step, an efficient image matching technique such as Semi Global Matching (SGM) is applied on UAV
