Method and device for positioning object and mobile terminal

The invention discloses a method and device for positioning an object and a mobile terminal. The object moves from a path starting point of a preset path to a path ending point, the preset path is constituted by making multiple line segments connected in sequence, each line segment comprises a corresponding line segment starting point, a line segment ending point, the smallest distance and the largest distance, and the distance between the path starting point and the path ending point is the largest length of the preset path. The method comprises the steps of obtaining a moving attribute and a moving time interval of the object, wherein the moving attribute comprises a current speed of the object and a current distance between the object and the path starting point; calculating and renewing the current distance according to the moving attribute and the moving time interval; comparing the current distance with the smallest distance and the largest distance of all the line segments to obtain the line segment co
