The Application of Digital Photogrammetry in Housing Construction Progress Tracking
In order to realize automatic monitoring of the construction status of a building project implemented in a development zone,this paper develops a system based on digital photogrammetry technology,which can be used to determine the progress of building construction throughout the entire building construction cycle and realize contin-uous monitoring.The developed system can be used to identify deviations between the construction progress and the planned progress and notify the decision makers via e-mail and SMS to facilitate him to make the appropriate decision in time.Finally,the system was tested by applying it to a construction site under construction,and the results show that the developed system has a horizontal accuracy of 100%,a vertical accuracy of more than 99.4%,and an overall accuracy of 100%,indicating that the system is highly reliable.
