The present invention relates to a disaster emergency management systems and methods, and more particularly, by the surveillance cameras as compared to the image information and the currently photographed image information of the construction site taken at regular time intervals sensing the deformation of the building structure, such as mold, and When the strain is a certain level or more of the detected structures by generating an alert, the present invention relates to a disaster emergency management system and method using photogrammetry that enable you to safely evacuate before the accident occurred.
Emergency disaster prevention system includes a plurality of LED light emission node 101 attached to the structure using such a photogrammetry and; A plurality of surveillance cameras to the desired distance from the observation of the LED light emission node 101 attached to the structure (103a, 103b) and; The surveillance cameras (103a, 103b) and one combined days plurality of measurement nodes (201a to transmit the image information recorded at regular intervals in each of the cameras for the surveillance (103a, 103b) over a network (205), 201b, 201c) and; Comparative analyzes the image information data which has been transmitted from the measurement nodes 201 determines the alarm state, is made, including the server node 203 for generating an alarm signal,
To emergency disaster prevention method using the photo survey according to the present invention easily recognize a variation of the structure through a camera for monitoring, and a target attachment step of attaching a sign consisting of a LED light emitting node 101 to the structure; And the initial reference measurement step of measuring the initial distance between the LED light emitting node 101 from the image information obtained through the camera 103 for the monitor; Displacement due to camera measuring step to calculate the distance between the LED light emitting node 101 from the image information obtained through the camera 103 for the monitoring and; Shift amount calculation step of calculating the stored measurement reference value from the initial stage, and calculates a stored value and the camera accumulated by accumulating the calculated displacement amount of displacement in the displacement measuring step by that, and; When the accumulated amount of displacement exceeds the predetermined reference value or more calculated by the shift amount calculation step and the risk value determination step of determining the risk value; When the risk value is determined from the risk value determining step alarm signal generating step of generating an alarm signal; comprises a.
In this way the disaster emergency system and method can prevent accidents at construction sites in advance, to detect signs of thinking in advance can prevent a major accident, the cause of the accident using photogrammetry according to the present invention comprising and to conveniently maintain research and analysis and records of disaster accidents, has the effect of easily preventing the recurrence of the cause analysis of accidents, there is an effect that allows the accident to the prevent recurrence prior to take measures for this .
