Referring to fig. 1, a flowchart of a method for determining a video playing sequence according to an embodiment of the present application includes:
Step S101, obtaining the distance from each boundary device to a boundary connecting point, wherein the distance is determined by position data acquired by the boundary device and GIS data of the boundary of the area;

For example, when the distances from each boundary device to boundary connecting points (a plurality of boundary connecting points corresponding to the inspection task form a boundary connecting line, i.e. a boundary area) are obtained, the calculation may be performed according to a spherical distance formula, for example:
acquiring longitude and latitude of boundary equipment and acquiring longitude and latitude of a boundary connecting point by using a GIS device;
determining the distance from the boundary equipment to the boundary connecting point by utilizing a spherical distance formula according to the longitude and latitude of the boundary equipment and the longitude and latitude of the boundary connecting point;
For another example, the distance s=r·arc cos [ cos β1cos β2cos (α1- α2) +sin β1sin β2], where R is the sphere radius, latitude angle β1, longitude angle α1, latitude angle β2, longitude angle α2, and the distance between the boundary device and the boundary connecting point is determined in the above manner.
