Monitoring and Management of Construction Sites Using Drone

Abstract

Drone is an emerging technology, recently the application of drone has been increased for the purpose of surveying. Drone surveying is safer and fast, compared to conventional method of surveying. Its a cost-efficient way of surveying in case of inaccessible areas. Drones are affordable, faster and has very less health and safety risks compared to setting up scaffolding and access platform. The usage of drones is rapidly increasing in various fields, due to the rapid growth in technology. It acts as a tool to monitor their construction projects visually. The examination of structures using drone helps in development of efficiency and quality of the structure. The GPS point of the construction site to be monitored is marked manually with the help of GPS essential mobile application. They are exported as kml file to google earth software to make a boundary map of the site, the GPS points at the corners of the site are connected to make the boundary map and exported in the form of kml. This file is manually imported in Drone deploy application and the flight path is made according to the direction of the site, the basic settings such as altitude, overlap, flight speed, etc. are made and set to fly. The input data is collected in form of images are imported to context capture master software. The camera properties of the input data are checked and aero triangulation, reconstruction settings are made and final production is done to get 3Dmodel output of the images. The required data is processed from the 3D model. IOT has the ability to transfer data over a network, when linked with API, which is an intermediatory software that allows two applications to communicate each other, it transfers message between systems. A basic system application is developed with help of python, and linked with API to send the data obtained from the processed 3D model.
