powering on the screen when screen recognition success information sent by the smart glasses is received; and

powering off the screen when each of the moving direction, the orientation of the screen, and the palm orientation is in a second direction, the second direction being different from the first direction.

2. The method of claim 1 , wherein the first direction is an upward direction, and the second direction is a downward direction.

3. The method of claim 1 , wherein detecting the moving direction of the mobile terminal comprises:

acquiring a gravity value detected by a gravity sensor in the mobile terminal;

determining that the moving direction of the mobile terminal is the first direction when the gravity value is greater than a first preset threshold; and

determining that the moving direction of the mobile terminal is the second direction when the gravity value is less than a second preset threshold, the first preset threshold being greater than the second preset threshold.

4. The method of claim 1 , wherein detecting the orientation of the screen comprises:

acquiring a Z-axis gravity value detected by a gravity sensor in the mobile terminal;

determining that the orientation of the screen is in the first direction when the Z-axis gravity value is a positive value; and

determining that the orientation of the screen is in the second direction when the Z-axis gravity value is a negative value.

5. The method of claim 1 , further comprising:

detecting a state of the screen;

performing the powering on the screen when the screen is in an off state; and

performing the powering off the screen when the screen is in an on state.

6. The method of claim 1 , wherein the wearable device includes a smart bracelet or a smart watch.

7. The method of claim 1 , wherein the first direction is a direction towards a face of the user, and the second direction is a direction away from the face of the user.

8. The method of claim 1 , wherein the screen recognition success information indicates a detection by the smart glasses that eyeballs of the user are looking at the mobile terminal.

9. A screen control method, comprising:

initiating, by smart glasses, a screen recognition operation when a screen recognition instruction sent by a mobile terminal is received;

acquiring, by the smart glasses, an image within a field of view of the smart glasses;

determining, by the smart glasses, whether the image contains a screen of the mobile terminal, wherein determining whether the image contains the screen of the mobile terminal comprises:

identifying feature information in the image;

acquiring a preset feature template of the screen of the mobile terminal;

determining whether the feature information matches the preset feature template;

determining that the image contains the screen of the mobile terminal when the feature information matches the preset feature template; and

determining that the image does not contain the screen of the mobile terminal when the feature information does not match the preset feature template;

generating, by the smart glasses, screen recognition success information when the image contains the screen of the mobile terminal; and

sending, by the smart glasses, the screen recognition success information to the mobile terminal.

10. A mobile terminal, comprising:

a processor; and

a memory configured to store instructions executable by the processor,

wherein the processor is configured to:

detect a moving direction of the mobile terminal;

detect an orientation of a screen of the mobile terminal;

receive posture recognition information sent by a wearable device, the posture information including a palm orientation of a user of the mobile terminal;

send a screen recognition instruction to smart glasses when each of the moving direction, the orientation of the screen, and the palm orientation is in a first direction;

power on the screen when screen recognition success information sent by the preset smart glasses is received; and

power off the screen when each of the moving direction, the orientation of the screen, and the palm orientation is in a second direction, the second preset direction being different from the first preset direction.

11. The mobile terminal of claim 10 , wherein the first direction is an upward direction, and the second direction is a downward direction.

12. The mobile terminal of claim 10 , wherein the processor is further configured to:

acquire a gravity value detected by a gravity sensor in the mobile terminal;

determine that the moving direction of the mobile terminal is the first direction when the gravity value is greater than a first preset threshold; and

determine that the moving direction of the mobile terminal is the second direction when the gravity value is less than a second preset threshold, the first preset threshold being greater than the second preset threshold.

13. The mobile terminal of claim 10 , wherein the processor is further configured to:

acquire a Z-axis gravity value detected by a gravity sensor in the mobile terminal;

determine that the orientation of the screen is in the first direction when the Z-axis gravity value is a positive value; and

determine that the orientation of the screen is in the second direction when the Z-axis gravity value is a negative value.

14. The mobile terminal of claim 10 , wherein the processor is further configured to:

detect a state of the screen;

perform the powering on the screen when the screen is in an off state; and

perform the powering off the screen when the screen is in an on state.

15. The mobile terminal of claim 10 , wherein the wearable device includes a smart bracelet or a smart watch.

16. The mobile terminal of claim 10 , wherein the first direction is a direction towards a face of the user, and the second direction is a direction away from the face of the user.

17. The mobile terminal of claim 10 , wherein the screen recognition success information indicates a detection by the smart glasses that eyeballs of the user are looking at the mobile terminal.

18. A smart terminal, comprising:

a processor; and

a memory configured to store instructions executable by the processor,

wherein the processor is configured to:

start a screen recognition operation when a screen recognition instruction sent by a mobile terminal is received;

acquire an image within a field of view of the smart terminal;

determine whether the image contains a screen of the mobile terminal, wherein in determining whether the image contains the screen of the mobile terminal, the processor is further configured to:

identify feature information in the image;

acquire a preset feature template of the screen of the mobile terminal;

determine whether the feature information matches the preset feature template;

determine that the image contains the screen of the mobile terminal when the feature information matches the preset feature template; and
