As the position coordinates of file belongs to target location coordinate set, not only refer to that target location coordinate set includes image text
Any position is sat in this situation of the position coordinates of part, in addition to the position coordinates distance objective position coordinates set of image file
Target distance is less than the situation of preset value.
Because target is being characterized with the set of discrete coordinate points comprising infinite more coordinate points in geographic area
During geographic area, it can only be characterized with the position coordinates of a portion point, though and other coordinate points in the geographic area
So it is not comprised in target location coordinate set, but undoubtedly belongs to target geographical area.In actual conditions, as long as from the target
Than relatively evenly extracting coordinate points as the element in target location coordinate set, then target location coordinate set in geographic area
A coordinate points are constantly present, is less than or equal to a certain threshold value with the distance of any coordinate points in target geographical area, can be expressed as：
Min | P1-Pi |≤T, Pi are any point in target location coordinate set, and T is threshold value.
In above-mentioned technical proposal, in the situation for the set that the form of expression of target location coordinate set is discrete coordinate
Under, the image file that the distance of either objective position coordinates in position coordinates distance objective position coordinates set is less than to threshold value is
