s2: obtaining an adjustment operation on the first cutting frame;
s3: adjusting the first cutting frame according to the adjusting operation to obtain a second cutting frame;
s4: and cutting the target view according to the second cutting frame.
2. The view clipping method according to claim 1, wherein the step S2 specifically includes at least one of:
carrying out movement adjustment operation on the first cutting frame;
carrying out deformation adjustment operation on the first cutting frame;
and carrying out rotation adjustment operation on the first cutting frame.
3. The view cropping method of claim 1, wherein the adjustment operation comprises:
triggering adjustment operation through a single contact; and/or the presence of a gas in the gas,
the adjustment operation is triggered by multiple contacts.
4. The view cropping method according to any one of claims 1 to 3, wherein said adjusting the first cropping frame according to an adjustment operation comprises:
adjusting the unilateral frame line of the first cutting frame; and/or the presence of a gas in the gas,
and adjusting the polygonal frame line of the first cutting frame.
5. The view clipping method according to any one of claims 1 to 3, wherein the step of S3 further comprises:
and providing at least one virtual control and/or physical button for auxiliary fine adjustment when the first cutting frame is adjusted according to the adjustment operation.
6. The view clipping method according to any one of claims 1 to 3, wherein the step of S1 specifically includes:
acquiring a starting point and an end point selected on the target view;
and automatically generating a first cutting frame according to the starting point and the end point in a preset mode.
7. The view clipping method according to claim 6, wherein the step of automatically generating the first clipping frame according to the starting point and the ending point in a predetermined manner specifically comprises:
acquiring a target path drawn from the starting point to the end point;
and fitting the starting point, the target path and the end point to obtain the first cutting frame.
8. An intelligent terminal, characterized in that it is provided with a processor for executing program data for implementing the view cropping method according to any one of claims 1 to 7.
9. The intelligent terminal according to claim 8, wherein the processor is further configured to display an adjustment result through a preview interface when the first cropping frame is adjusted according to the adjustment operation.
10. The intelligent terminal of claim 9, wherein the processor is further configured to provide a cancel button for selectively canceling the adjustment operation.
11. A computer-readable storage medium for storing program data which, when executed by a processor, implements a view cropping method as claimed in any one of claims 1 to 7.
