Method and device for tracking of structure physical simulation experiment surface particles

The present invention provides a method and device for tracking of structure physical simulation experiment surface particles. The method comprises: a step of arrangement of mark points: arranging mark points at a measured position on an experiment model of a structure physical simulation experiment; a step of data measurement: performing non-contact optical projection three-dimensional topographymeasurement for the experiment model in each preset duration in a process of the structure physical simulation experiment, and obtaining feature data of the mark points; and a step of data processing: performing orientation calculation of the feature data of the mark points, and obtaining changing information of a measured position on the experiment model. Compared to a current method, the methodprovided by the invention completely overcomes defects that a current method performs qualitative analysis and research through intelligent artificial observation of experiment accomplishment imagesor repeat observation of vi
