Example one
Referring to fig. 1 to fig. 3 and fig. 4, fig. 4 is a schematic flowchart of an image capturing calibration method based on a wearable device according to an embodiment of the present invention. As described in the foregoing embodiments, the wearable device includes the smart host rotatably connected to the bottom bracket of the wearable device, the smart host includes the host top surface and the host bottom surface opposite to each other, and the host top surface and the host bottom surface are respectively provided with one shooting module. As shown in fig. 4, the image capturing correction method based on the wearable device may include the steps of:
401. when detecting a start instruction of the time-delay shooting, the intelligent host detects the angular velocity of a gyroscope arranged on the intelligent host.
In the embodiment of the invention, the method can be applied to the process that a wearable device user starts a delayed shooting function of the wearable device to carry out self-shooting, and the final shot image and the image in the view finding range set in the delayed shooting process have a certain inclination angle due to no shake of the stabilized intelligent device.
As an optional implementation manner, the manner of starting the delayed shooting function by the smart host may be by detecting a click start operation, a voice input start instruction, or a gesture action start instruction of the user for the delayed shooting function. If the gesture is the gesture motion, further, the intelligent host can recognize the gesture motion of the user and acquire related characteristics, and when the characteristics of the gesture motion are matched with the preset gesture outline characteristics, a time delay shooting timer is started to time; and when the timing of the preset duration is finished, triggering the shooting action. By implementing the implementation mode, the user can conveniently start the time-delay shooting function, and the influence on the setting of the view angle due to the start of the time-delay shooting is reduced.
402. When the angular speed of the gyroscope is smaller than the preset angular speed and the duration that the angular speed of the gyroscope is smaller than the preset angular speed is equal to or larger than the preset duration, the intelligent host acquires first angle information of the gyroscope at the current moment, controls the target shooting module to shoot to acquire a first image and a main scene area subgraph in the first image, and the target shooting module comprises a shooting module on the top surface of the host or a shooting module on the bottom surface of the host.
In the embodiment of the present invention, as can be seen from the description of the foregoing embodiment, before the user wearing the wearable device performs the delayed shooting by using the wearable device, the shooting angles of the shooting module 22 and the shooting module 23 can be adjusted by adjusting the rotation angle of the smart host 20 and the bottom bracket 10. Particularly, when the top surface display screen is arranged on the top surface 20 of the host computer 20 and the bottom surface display screen is also arranged on the bottom surface 20b of the host computer, if the included angle between the shooting module 22 and the shooting module 23 of the host computer 20 relative to the bottom bracket 10 is 90 degrees, then the included angle between the top surface display screen arranged on the top surface 20a of the host computer and the bottom surface display screen arranged on the bottom surface 20b of the host computer relative to the bottom bracket 10 is also 90 degrees, so that the user on one side of the host computer 20 can watch the top surface display screen to perform self-shooting conveniently, and the user on the other side of the host computer 20 watches the bottom surface display screen to perform self-shooting conveniently.
In the embodiment of the present invention, the rotation angle between the intelligent host 20 and the bottom bracket 10 can be adjusted between 0 ° and 90 °, and preferably, the rotation angle can be 0 °, 30 °, 45 °, 60 °, 75 °, or 90 °.
Alternatively, the target shooting module can be the shooting module 22 on the top surface of the host, and can also be the shooting module 23 on the bottom surface of the host.
As an optional implementation manner, the intelligent host may further obtain angle information of the plurality of gyroscopes within a duration that the angular velocity of the gyroscope is less than a preset angular velocity, and control the target shooting module to obtain the plurality of frames of images; and taking the angle information with the minimum corresponding angular speed in the angle information of the gyroscopes as first angle information, taking an image acquired by the target shooting module at the moment corresponding to the first angle information as a first image, and acquiring a main scene area subgraph in the first image. The smaller the angular velocity of the gyroscope is, the smaller the inclination angle of the intelligent host is, and the more stable the intelligent host is. By implementing the embodiment, the image acquired at the moment corresponding to the minimum angular velocity within the duration of the gyroscope angular velocity being less than the preset angular velocity can be acquired, the image acquired under the condition that the intelligent host is most stable within the duration of the gyroscope angular velocity being less than the preset angular velocity can be acquired, and therefore the accuracy of the inclination angle can be improved, and the accuracy of image correction can be improved.
403. When detecting a timing ending instruction of the time-delay shooting, the intelligent host acquires second angle information of the gyroscope and controls the target shooting module to shoot to acquire a second image.
As an optional implementation manner, when the intelligent host detects a timing end instruction of the delayed shooting, after acquiring second angle information of the gyroscope, the intelligent host may acquire an angular velocity corresponding to the second angle information and determine whether the angular velocity corresponding to the second angle information of the gyroscope is smaller than a preset angular velocity; if not, popping up a prompt message, wherein the prompt message is used for reminding the user that the wearable equipment is unstable. By implementing the implementation mode, the user can conveniently know that the wearable device is unstable and can perform the rephotography operation when the timing of the delayed shooting is finished, and then the shooting effect and the user experience are improved.
404. And the intelligent host obtains the inclination angle of the intelligent host according to the first angle information and the second angle information.
In the embodiment of the present invention, optionally, the average angular velocity of the gyroscope may be obtained according to a first angular velocity corresponding to the first angle information of the gyroscope and a second angular velocity corresponding to the second angle information; and acquiring the duration of the gyroscope from the first angular speed to the second angular speed, and calculating to obtain the inclination angle of the intelligent host according to the average angular speed of the gyroscope and the duration of the gyroscope.
405. The intelligent host judges whether the inclination angle is smaller than a preset inclination angle; if yes, go to step 406; otherwise, the flow is ended.
As an optional implementation manner, if the inclination angle is smaller than the preset inclination angle, it is determined that the inclination angle of the intelligent host is caused by shaking; if the inclination angle is equal to or larger than the preset inclination angle, the inclination angle of the intelligent host is judged to be caused by artificial angle replacement. Based on the above, when the inclination angle of the intelligent host is larger than or equal to the preset inclination angle, the second image is taken as the target image and is stored. By implementing the embodiment, the second image can be not processed under the condition that the angle of the user is manually changed, so that the shooting effect and the user experience are improved.
406. The intelligent host judges whether the second image contains a main scene area subgraph or not; if yes, go to step 407; otherwise, the flow is ended.
In most embodiments of the invention, the main scene area sub-image comprises a self-portrait character; in some embodiments, the main scene region subgraph may also include the main scene. The embodiments of the present invention are not limited.
407. And the intelligent host processes the second image according to the inclination angle to obtain and store a target image.
In the embodiment of the present invention, the second image may be rotated according to the inclination angle to obtain the same viewing angle as the set viewing range, and the target image may be obtained by cropping.
As can be seen, in the method described in fig. 4, in the process of starting the time-delay shooting function, when the intelligent host detects that the angular velocity of the gyroscope is less than the preset angular velocity and the duration of the angular velocity of the gyroscope that is less than the preset angular velocity is equal to or equal to the preset duration (i.e., when the gyroscope tends to be stable), the first angle information of the intelligent host is obtained and the first image is obtained by shooting, the main scene area sub-image in the first image is obtained, the second angle information of the intelligent host is obtained at the timing end of the time-delay shooting function and the second image is obtained by shooting, the inclination angle is obtained according to the first angle information and the second angle information of the intelligent host, when the inclination angle is less than the preset inclination angle and the second image contains the main scene area, the second image is corrected according to the inclination angle to obtain the target image, so that the problem between the finally shot image and the image in the view range set in the process of the time-delay The problem of certain inclination exists, and the shooting effect is improved.
In addition, the user can conveniently start the time-delay shooting function, and the influence on the setting of the view angle due to the start of the time-delay shooting is reduced; the image acquired under the condition that the intelligent host is most stable within the duration that the angular velocity of the gyroscope is less than the preset angular velocity can be acquired, so that the accuracy of the inclination angle can be improved, and the accuracy of image correction is improved.
In addition, the user can know that the wearable device is unstable and can perform repeated shooting operation when the timing of delayed shooting is finished, and therefore shooting effect and user experience are improved; the second image can be not processed under the condition that the angle of the user is changed manually, and therefore the shooting effect and the user experience are improved.

As shown in fig. 5, the image capturing correction method based on the wearable device may include the steps of:
501. when detecting a start instruction of the time-delay shooting, the intelligent host detects the angular velocity of a gyroscope arranged on the intelligent host.
502. When the angular speed of the gyroscope is smaller than the preset angular speed and the duration time that the angular speed of the gyroscope is smaller than the preset angular speed is equal to or greater than the preset duration time, the intelligent host acquires first angle information of the gyroscope at the current moment, controls the target shooting module to shoot within the specified duration time to acquire a plurality of frame images, compares the plurality of frame images, acquires an image with the highest definition in the plurality of frame images as a first image, acquires a pixel point combination with the highest coincidence degree in the plurality of frame images as a main scene area sub-image, and the target shooting module comprises a shooting module on the top surface of the host or a shooting module on the bottom surface of the host.
In the embodiment of the invention, the main scene area subgraph can be a character or a main scene, and the pixel point with the highest coincidence degree in a plurality of frames of images is used as the main scene area subgraph, so that the range of the main scene area subgraph can be more accurately determined.
As an alternative implementation, the first image may be cropped according to a certain size ratio to obtain a main scene area sub-image of the first image. By implementing the implementation mode, the size of the main scene region subgraph can be ensured, and the range of the main scene region subgraph is further determined more accurately.
503. When detecting a timing ending instruction of the time-delay shooting, the intelligent host acquires second angle information of the gyroscope and controls the target shooting module to shoot to acquire a second image.
504. And the intelligent host obtains the inclination angle of the intelligent host according to the first angle information and the second angle information.
505. The intelligent host judges whether the inclination angle is smaller than a preset inclination angle. If yes, go to step 506; otherwise, the flow is ended.
506. And the intelligent host judges whether the second image contains the main scene area subgraph. If yes, go to step 507; otherwise, step 509 is performed.
507. And the intelligent host rotates the second image according to the inclination angle and cuts out the region except the target rectangular region, wherein the target rectangular region comprises a main scene region sub-image.
508. And the intelligent host adjusts the size of the target rectangular area to a preset size, and obtains and stores a target image.
As an optional implementation manner, the intelligent host processes the second image according to the inclination angle, obtains the target image, and after the target image is stored, light supplement can be performed on the target image. Specifically, whether the target image includes a light source area or not can be judged, if so, the target shooting module is controlled to perform spot light measurement processing on the light source area, the brightness of the target image is adjusted according to the spot light measurement processing result, a target preview image is obtained, and the target preview image is saved when a saving instruction of a user is detected. By implementing this embodiment, the photographing effect can be improved.
509. And the intelligent host takes the first image as a target image and stores the target image.
It can be seen that, in the process of starting the time-delay shooting function, when the intelligent host detects that the angular velocity of the gyroscope is less than the preset angular velocity and the duration of the angular velocity of the gyroscope that is less than the preset angular velocity is equal to or equal to the preset duration (i.e. when the gyroscope tends to be stable), the method described in fig. 5 is implemented, by obtaining the first angle information of the intelligent host and shooting to obtain the first image and the main scene area sub-image in the first image, obtaining the second angle information of the intelligent host and shooting to obtain the second image at the timing end of the time-delay shooting function, obtaining the inclination angle according to the first angle information and the second angle information of the intelligent host, and correcting the second image according to the inclination angle to obtain the target image when the inclination angle is less than the preset inclination angle and the second image contains the main scene area, the final shot image and the image within the view range set in the time-delay shooting function can be solved The problem of certain inclination angle exists between the two, and the shooting effect is improved.
In addition, the implementation of the method described in fig. 5 can also ensure the size of the main scene area subgraph, thereby more accurately determining the range of the main scene area subgraph and improving the shooting effect.
