Abstract
A photographing direction deviation detection method is provided for a deviation detection device. The method includes obtaining a horizontal acceleration of an image capturing device at each of a plurality of time points in a pre-determined time period, and determining a target photographing direction of the image capturing device according to the horizontal acceleration at each of the time points. The method also includes, when a direction angle satisfies a preset condition, determining that an actual photographing direction of the image capturing device deviates, where the direction angle is an angle between the target photographing direction and the actual photographing direction of the image capturing device at an end time point of the pre-determined time period.
