关 键 词：virtual instrument laser image deformation monitoring microcontroller wireless transmission
摘 要：According to the actual demand of deformation monitoring for large buildings, the technology of laser image based on virtual instrument is put forward. The location of laser light spot relative to the reference position and the variation of tilt angle are measured, which can calculate the vertical deformation value of displacement. In the measurement process, it uses the function library of image processing in Lab VIEW to perform the read and processing of image, which has the advantages of convenient operation and accuracy location of measurement spot center In order to satisfy the requirement of on-line monitoring, the measurement data is transmitted to the host computer for operation and display using the way of wireless. The measurement data can be read in real time and can also be saved for the inquiry.
