Abstract: A setting method of a counting flow path is applied to an image monitoring system and a related computer-readable media. The counting flow path is utilized to determine whether an object passes through a monitoring area. The setting method includes drawing two boundaries on a video frame correlative to the monitoring area to define the counting flow path, detecting relative position between a first angle control point and a second angle control point of the counting flow path, adjusting an angle formed by virtual lines stretching from the boundaries according to the relative position between the said angle control points, and utilizing an initial point and a final point detected by the counting flow path while the objects moves into or out of the counting flow path to determine whether the object passes through the counting flow path.
