Method and device for constructing missing part of target movement track of object

The present invention discloses a method and device for constructing a mission part of a target movement track of an object. The method comprises determining frequent points whose occurrence number is larger than a first threshold value on a historical movement track of the object; selecting at least one track zone whose reliability is larger than a second threshold value from track zones, comprising the frequent points, on the historical movement track, the reliability indicating the same possibility of the track zone as of the missing part of the target movement track of the object; and constructing the missing part by using the selected at least one track zone. The method and the device do not rely on the map and road grid of a region where the object is disposed, and the missing part of the target movement track can be accurately constructed.
