Specifically, if the moving speed of the mobile terminal acquired within a certain shooting time interval is greater than or equal to a preset threshold, it can be considered that shooting is abnormal in this shooting time period, and the segmented panoramic image acquired within the shooting time period is marked. Specifically, the shooting start time and the shooting end time of this segmented panoramic image can be obtained.
If the moving speed of the mobile terminal acquired in a certain shooting time period is smaller than a preset threshold value, the mobile terminal is considered to belong to normal shooting in the shooting time period.
And 103, judging whether a target segmented panoramic image exists in the panoramic image.
In this step, it is determined whether there is a segmented panoramic image with a marker in the panoramic image.

And acquiring the moving speed of the mobile terminal in the moving and shooting processes of the mobile terminal according to the panoramic image shooting instruction. After the moving speed of the mobile terminal is obtained, the obtained moving speed is compared with a preset threshold value, a shooting time period in which the moving speed of the mobile terminal is greater than or equal to the preset threshold value is obtained, and the segmented panoramic image obtained in the shooting time period is marked. Specifically, if the moving speed of the mobile terminal acquired within a certain shooting time interval is greater than or equal to a preset threshold, it can be considered that shooting is abnormal in this shooting time period, and the segmented panoramic image acquired within the shooting time period is marked. Specifically, the shooting start time and the shooting end time of this segmented panoramic image can be obtained.
If the moving speed of the mobile terminal acquired in a certain shooting time period is smaller than a preset threshold value, the mobile terminal is considered to belong to normal shooting in the shooting time period.
For example, assuming that the moving speed of the mobile terminal obtained within a certain photographing period is V, if a1< V < a2(a1 is smaller than a2), the photographing period belongs to normal panorama photographing; if V > is A3, the shooting time section belongs to shooting abnormity, and simultaneously the shooting panoramic image in the shooting time section is marked to obtain the shooting start time and the shooting end time.
