Abstract
A data filtering device stores a piece of standard track data and a piece of target track data. The piece of standard track data corresponds to a standard track in a six degree-of-freedom (DoF) virtual space constructed by a plurality of virtual space units, and the piece of target track data corresponds to a target track in the six-DoF space. The data filtering device determines whether a degree of similarity between the standard track and the target track is lower than a threshold of similarity. When determining that the degree of similarity is lower than the threshold of similarity, the data filtering device classifies the piece of target track data as an invalid data.
