Abstract

Abstract: As the scale of construction sites increases, it's becoming more and more difficult to understand the status of construction sites timely. Thanks to the development of Unmanned Aerial Vehicle technology, a large number of image data of construction sites can be collected in a short time. Utilizing these data, large-scale construction sites can be monitored effectively using computer vision technology in real time. In this paper, a method of image stitching for panorama of construction site is proposed, which adopts the strategy of filtering fuzzy frame, selecting key frame and correcting camera lens distortion. This method produces a complete panorama of high quality, which helps to identify various construction site environments in the context of high-quality image data.
