First elasticity information regarding elasticity of a subject in a first image and second elasticity information regarding the elasticity of the subject in a second image are acquired, and the first image and the second image are positioned with respect to each other on the basis of at least one of the first elasticity information and the second elasticity information.

The invention discloses a method for determining the travel track of a mobile terminal. The method comprises the following steps: (1) removing drifting track points with abnormal distance in a track sequence by filtering; (2) if the positioning radiuses of any two or more track points which are adjacent in time in sequence in the track sequence intersect, merging the track points which serve as candidate retention track points to obtain a new track sequence which is formed by the candidate retention track points and movement track points; (3) segmenting the candidate retention track points in the new track sequence, calculating the speed of each movement track point in each track sequence segment, and removing the movement track points of which the speed is higher than the set value by filtering; and (4) setting the clustering radiuses of all the candidate retention track points in the new track sequence, and clustering the candidate retention track points in the new track sequence by taking the candidate retention track points as the center of a circle to obtain a final travel track sequence. Useless drifting track points in the travel track sequence of the mobile terminal can be removed by filtering, and thus the accurate position information and the clear travel track of a user can be obtained.
