1. A data marking method, comprising:
acquiring multiple pictures whose contents are continuous, wherein the multiple pictures contain at least one same object;
for each object, determining a position offset of the object by using position information of the object in two adjacent pictures, wherein the two adjacent pictures include a first previous picture and a second previous picture, the first previous picture is a picture before and adjacent to a picture to be marked in time sequence; the second previous picture is a picture before and adjacent to the first previous picture in time sequence;
determining estimated position information of the object in the picture to be marked based on the position information of the second previous picture and the position offset;
marking the object in the picture to be marked based on the estimated position information;
displaying the estimated position information;
receiving corrected estimated position information obtained by correcting the estimated position information;
wherein marking the object in the picture to be marked based on the estimated position information, comprises:
marking the corrected estimated position information in the picture to be marked, and marking an identifier of the object at a position determined based on the corrected estimated position information, which comprises:
taking the corrected estimated position information as the position of the object in the picture to be marked, and marking the identifier of the object at the position; or
taking the corrected estimated position information as a center point of a rectangle, and drawing the rectangle from the center point, the rectangle being a rectangular box for the object, and marking the identifier of the object at the position of the rectangular box.
