It is an innovation that we use digital close-range photogrammetry method to monitor the deformation of the steel goods shelf instead of traditional method. Digital camera is not for professional measurement, and it has no fiducially mark and orientation equipment, so we can't obtain the initial values of internal-external azimuth while photographing instantly. So the traditional methods can't process measurement data, and it will be superior to use Spatial Time Baseline Parallax Method. In this paper, we will introduce a method to process deformation measurement data of steel goods shelf by spatial Time Baseline Parallax Method and obtain the experiment results. This method considers of the influence of the resolution ratio, fatal distance, outside environment and eliminates them effectively, so we got a good results that the monitoring error is less than 30/00.
