Abstract

The present application relates to a three-dimensional model representation device, comprising: a real image acquisition unit generates an electronic three-dimensional model; a detection area calibration unit calibrates the area to be detected on the object to be detected; a normal calibration unit determines the normal of a surface to be measured of the object to be detected; an angle measurement unit outputs an angle detection signal by real-time detecting the angle between an orientation line of the detection area calibration unit 12 and the normal; a ranging unit is configured to determine a distance between the three-dimensional model representation device and the object to be detected along the normal direction and output a distance detection signal; calculating the distance between the three-dimensional model representation device and the area to be detected based on a preset calculation method; an image projection unit determines a relative position of the three-dimensional model representation device and the object to be detected; establishing a virtual projection scene according to the electronic three-dimensional model and the relative position between the electronic three-dimensional model and the object to be detected; projecting the electronic three-dimensional model corresponding to the area to be detected onto the area to be detected. The present application has an effect of reducing a difficulty of obtaining location information for a concealed work.
