Abstract

The application discloses an intelligent equipment-based motion sensing control method, an electronic device, and intelligent equipment. The method includes the steps: collecting user image data; according to the user image data, acquiring an image contour of a user; according to the image contour, acquiring a first motion track of the user on an imaging plane; according to the change of a characteristic length on the image contour and/or the change of a focal distance of a camera, acquiring a second motion track of the user in a direction perpendicular to the imaging plane; and according to the first motion track and the second motion track, generating motion sensing data.

First claim

1 . An intelligent equipment-based motion sensing control method, the intelligent equipment being provided with a camera, comprising:
collecting user image data; acquiring an image contour of a user, according to the user image data; acquiring a first motion track of the user on an imaging plane, according to the image contour; acquiring a second motion track of the user in a direction perpendicular to the imaging plane, according to the change of a characteristic length on the image contour and/or the change of a focal distance of the camera; and generating motion sensing data, according to the first motion track and the second motion track.

2 . The method according to claim 1 , wherein, the characteristic length comprises a hand contour length/width, a leg contour length/width or a head contour length/width.

3 . The method of claim 1 , further comprising:
separating a user image from a foreground and a background, between the steps of collecting user image data and acquiring an image contour of a user according to the user image data.

4 . The method according to claim 1 , between the steps of acquiring a second motion track of the user in a direction perpendicular to the imaging plane according to the change of a characteristic length on the image contour and/or the change of a focal distance of the camera and generating motion sensing data according to the first motion track and the second motion track, further comprising:
calibrating the second motion track according to the distance from each portion of the body of the user to the camera, which is obtained by the measurement of a distance measurement module.

5 . The method according to claim 4 , wherein, the distance measurement module is an infrared distance measurement module or a laser distance measurement module.

6 . An electronic device, comprising: at least one processor; and a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, wherein execution of the instructions by the at least one processor causes the at least one processor to:
collect user image data; acquire an image contour of a user according to the user image data; acquire a first motion track of the user on an imaging plane according to the image contour; acquire a second motion track of the user in a direction perpendicular to the imaging plane according to the change of a characteristic length on the image contour and/or the change of a focal distance of the camera; and generate motion sensing data according to the first motion track and the second motion track.

7 . The electronic device according to claim 6 , wherein, a user image is separated from a foreground and a background between the steps of collecting user image data and acquiring an image contour of a user according to the user image data.

8 . The electronic device according to claim 6 , wherein, the second motion track is calibrated between the steps of acquiring a second motion track of the user in a direction perpendicular to the imaging plane according to the change of a characteristic length on the image contour and/or the change of a focal distance of the camera and generating motion sensing data according to the first motion track and the second motion track, according to the distance from each portion of the body of the user to the camera, which is obtained by the measurement of a distance measurement module.

9 . A non-transitory computer-readable storage medium storing executable instructions that, when executed by an electronic device, cause the electronic device to:
collect user image data; acquire an image contour of a user according to the user image data; acquire a first motion track of the user on an imaging plane according to the image contour; acquire a second motion track of the user in a direction perpendicular to the imaging plane according to the change of a characteristic length on the image contour and/or the change of a focal distance of the camera; and generate motion sensing data according to the first motion track and the second motion track.

10 . The non-transitory computer-readable storage medium according to claim 9 , wherein, the characteristic length comprises a hand contour length/width, a leg contour length/width or a head contour length/width.

11 . The non-transitory computer-readable storage medium according to claim 9 , wherein, between the steps of collecting user image data and acquiring an image contour of a user according to the user image data, further comprising:
separating a user image from a foreground and a background.

12 . The non-transitory computer-readable storage medium according to claim 9 , wherein, between the steps of acquiring a second motion track of the user in a direction perpendicular to the imaging plane according to the change of a characteristic length on the image contour and/or the change of a focal distance of the camera and generating motion sensing data according to the first motion track and the second motion track, further comprising:
calibrating the second motion track according to the distance from each portion of the body of the user to the camera, which is obtained by the measurement of a distance measurement module.

13 . The non-transitory computer-readable storage medium according to claim 12 , wherein, the distance measurement module is an infrared distance measurement module or a laser distance measurement module.
