A construction site process management system using a drone, comprising: a data transmission/reception terminal 500 that transmits and receives data to and from the drone controller 300 and the process management server 200.
The method according to claim 1,
When the drone 100 and the drone controller 300 are rented, the construction site process management system using the drone processes payment for the rented drone 100 and the drone controller 300 in units of a set period. Construction site process management system using a drone, characterized in that the financial company server 400 is further configured for.
Step of inputting an image and basic information for inputting an external expression element (EO) and a ground reference point (GCP) to the drone 100 (S100);
While operating the drone 100 (S110), the drone 100 observes the ground reference point (GCP) through a camera unit, stores an image while photographing, and transmits it to the drone controller 300 (S120) ;
Transmitting the image data transmitted to the drone controller 300 to the process management server 200 through the drone controller 300 or a separate data transmission/reception terminal 500 when the preset operation is completed (S150);
The process management server 200 classifies the transmitted data, extracts a point cloud from the classified data, and produces a digital surface model (DSM) and a digital elevation model (DEM) using a point classification technique ( S160);
The process management server 200 is a step of producing an ortho image and updating data by producing a true ortho lmage or a normal ortho lmage using DSM and DEM (S170); And
The process management server 200 compares the pre-designed data of the construction site in the produced orthogonal image to perform process management including current progress, misconstruction, and overconstruction, and incorrect construction/overconstruction/danger. Monitoring the normal input of local video and pre-contracted construction equipment and materials, preventing and monitoring illegal export of on-site materials, displaying an abnormality on the monitor, and transmitting it to the smartphone of the person in charge (manager) (S190) Construction site process management method using a construction site process management system using a drone, characterized in that consisting of;
