1. A photographing direction deviation detection method, comprising:
obtaining, by a deviation detection device, a horizontal acceleration of an image capturing device at each of a plurality of time points in a pre-determined time period;
calculating, by the deviation detection device, a horizontal moving speed of the image capturing device at each of the plurality of time points according to the horizontal acceleration;
setting, by the deviation detection device, a weight for the horizontal moving speed at each of the plurality of time points;
obtaining, by the deviation detection device, an aggregated horizontal moving speed of the pre-determined time period according to the horizontal moving speed and the weight for the horizontal moving speed at each of the plurality of time points;
determining, by the deviation detection device, a target photographing direction of the image capturing device according to the aggregated horizontal moving speed
calculating a direction angle between the target photographing direction and an actual photographic direction of the image capturing device; and
when the direction angle satisfies a preset condition, determining, by the deviation detection device, that the actual photographing direction of the image capturing device deviates.
