Description

Video presentation method of intelligent mobile terminal

Technical field

The invention relates to a video presentation method of an intelligent mobile terminal.

Background technique

Usually, when the user takes a panoramic photo, the mobile phone needs to keep the mobile phone moving in a horizontal or vertical direction at a stable and uniform speed. The mobile phone splicing and synthesizing the photos through a software method, which has a relatively high requirement for the photographer, and a slight instability may result in the stitching not being caused. Traces of nature. When viewers view a panoramic photo, because the panorama is often long or wide, the viewer needs to slide the photo to view the photo panorama.

Similarly, if the photographer takes a video to capture a panorama, the viewer can watch the video directly because of the lack of substitution, just watching the video directly.

Summary of the invention

The technical problem to be solved by the present invention is to provide a video presentation method for an intelligent mobile terminal that allows a viewer to have the same immersive experience as a photographer when viewing a video file.

The technical solution adopted by the present invention to solve the above technical problem is: a video presentation method for an intelligent mobile terminal, characterized in that: when the video is captured by the intelligent mobile terminal, the displacement or/and rotation of the smart mobile terminal during the shooting process is recorded. Information, and then the displacement or/and rotation information of the smart mobile terminal during the shooting process is saved together with the captured video file; when the smart mobile terminal plays the aforementioned video file, the displacement of the smart mobile terminal during viewing or / and rotation information, if the displacement or/and rotation information during viewing matches the displacement or/and rotation information during shooting, the aforementioned video file is played.

As an improvement, when the video is captured by the smart mobile terminal, the data collected by the acceleration sensor and the record of the intelligent mobile terminal are opened by the acceleration sensor device that can detect the rotational acceleration or/and the movement acceleration of the intelligent mobile terminal. Time, obtain the displacement or/and rotation information of the smart mobile terminal during the shooting process; when the smart mobile terminal plays the aforementioned video file, turn on the rotation acceleration or/and the movement acceleration of the smart mobile terminal that is self-contained in the mobile terminal. The acceleration sensor device obtains the displacement or/and rotation information during the viewing process of the smart mobile terminal by using the data collected by the acceleration sensor and the time recorded by the intelligent mobile terminal.

In practical applications, the displacement accuracy detected by the acceleration sensor device is low, and only the approximate motion direction and displacement can be judged. In order to improve the accuracy, the image information collected by the camera can be analyzed for auxiliary processing, that is, using an intelligent mobile terminal. When shooting a video, first detect the video during the shooting by pressing the frame on the video screen of the video file. Displacement or / and the direction and relative distance of the rotation information, and then obtain the displacement information of the intelligent mobile terminal during the shooting process by the data collected by the acceleration sensor and the time recorded by the intelligent mobile terminal; when the smart mobile terminal plays the aforementioned video file Open the front camera of the intelligent mobile terminal, take the front picture, and also detect the direction and relative distance of the displacement information of the positioning process by the frame to the front picture, and then collect the data collected by the acceleration sensor, and the smart mobile terminal At the time of recording, the displacement information of the intelligent mobile terminal during the viewing process is obtained.

As an improved technical solution, if the displacement or/and rotation information during the viewing does not match the displacement or/and the rotation information during the shooting, and the displacement or/and the rotation speed during the viewing is more than the displacement or/and during the shooting. The rotation speed is fast, and the aforementioned video file is quickly played; if the displacement or/and rotation information during the viewing does not match the displacement or/and the rotation information during the shooting, and the displacement or/and the rotation speed during the viewing is higher than during the shooting If the displacement or/and the rotation speed is slow, the slow motion lens puts the aforementioned video file; if the viewer stops moving, the video file is stopped.

The displacement information of the smart mobile terminal during the viewing process or the shooting process can be obtained by:

Let the starting speed of the intelligent mobile terminal be 0, the displacement distance be 0, the period of the acceleration sensor device of the intelligent mobile terminal collecting data is ti, and the acceleration of the acceleration sensor device of the intelligent mobile terminal instantaneously collecting ai, then the intelligent mobile terminal Instantaneous speed

Displacement information of intelligent mobile terminal

In order to improve the smoothness during playback, a low-pass filter may be applied to the acceleration of calculating the displacement information, that is, the displacement information of the smart mobile terminal during the viewing process or the shooting process is obtained by:

Let the starting speed of the intelligent mobile terminal be 0, the displacement distance be 0, the period of the data collected by the accelerometer device of the intelligent mobile terminal is t _i , and the acceleration of the accelerometer device of the intelligent mobile terminal instantaneously collected is a _i , the calculation is low The filtered acceleration will be a _i ', a _i '=0.3*a _i +0.7*a _i-1 , the instantaneous speed of the intelligent mobile terminal

Displacement information of intelligent mobile terminal

It is difficult for the user to move at a constant speed when shooting or watching, and even when the playback is played, there is still jitter. To eliminate the jitter, when the smart mobile terminal plays the video file, set a buffer with a buffer size of 10-20. Frame, the buffer enters the frame sequence number of the video file to be played. When the smart mobile terminal plays the video file, set a buffer with a buffer size of 10 to 20 frames. The buffer inputs the video file to be played. The frame sequence number is then output in the order of the frame sequence to play the aforementioned video file.

In order to be more convenient to use, the present invention also provides a certain tolerance to the deviation of the displacement or/and the rotation information, that is, the displacement or/and the rotation information during the viewing and the deviation of the displacement or/and the rotation information during the shooting are preset. Fault tolerance Within the range, it is considered that the displacement or/and rotation information during the viewing matches the displacement or/and rotation information during the shooting.

Different from the usual playing mode, the present invention uses a user to move (rotate) a mobile phone to watch a video. In order to provide an intuitive and simple interactive prompt, as an improved technical solution, when the smart mobile terminal plays the aforementioned video file, the video file playing interface is simultaneously The smart mobile terminal is prompted to shift or/and rotate information during the shooting process, and the viewer moves or rotates the smart mobile terminal according to the displacement or/and rotation information prompted by the video file playing interface.

Compared with the prior art, the invention has the advantages that: in addition to saving audio and video information, the present invention saves displacement (rotation) information, allowing viewers to experience video from another new media dimension, by communicating The displacement or / rotation information, the displacement or / and rotation of the viewer in synchronization with the photographer improves the immersion when watching the video. This new way of playing video is not a traditional time-based variable to display video pictures in frames, but to display pictures in frames according to displacement (rotation) variables; the present invention can replace the panoramic photo shooting and browsing experience, reducing the photographer The stability requirements require that the panoramic angle of the shooting is arbitrarily large (a 360 can be supported), the shooting direction is arbitrary (up, down, left, right, and beveled), and the viewer's viewing experience is more rich and interesting.

detailed description

The invention will be further described in detail below with reference to the embodiments of the drawings.

The invention provides a video presentation method for an intelligent mobile terminal, wherein the main feature is: when the video is captured by the intelligent mobile terminal, the displacement or/and rotation information of the smart mobile terminal during the shooting process is recorded, and then the smart mobile terminal is The displacement or/and rotation information during the shooting is saved with the captured video file; when the smart mobile terminal plays the aforementioned video file, the displacement or/and rotation information during the viewing process of the smart mobile terminal is also recorded, such as If the displacement or/and rotation information during viewing matches the displacement or/and rotation information during shooting, the aforementioned video file is played.

Of course, if the displacement or/and rotation information during the viewing does not match the displacement or/and the rotation information during the shooting, and the displacement or/and the rotation speed during the viewing is faster than the displacement or/and the rotation speed during the shooting , the above video file is played quickly; if the displacement or/and rotation information during the viewing does not match the displacement or/and rotation information during the shooting, and the displacement or/and the rotation speed during the viewing is shifted compared to during the shooting or / And the rotation speed is slow, the slow lens puts the aforementioned video file; if the viewer stops moving, the above video file is stopped.

The following describes in detail the different implementations of this implementation:

[Detecting displacement information by acceleration sensor]

When the smart mobile terminal captures video on the mobile, the acceleration sensor can know the direction and size of the acceleration motion of the smart mobile terminal in space. Different intelligent mobile terminals have different acceleration sensors, which can measure the moving acceleration and rotational acceleration of the intelligent mobile terminal respectively. The acceleration sensor system interface and data precision are also different. The mainstream includes moving acceleration sensors (for measuring moving acceleration) and gyro. Instrument (used to measure the rotational acceleration), we discuss the mobile acceleration sensor with higher popularity in this implementation. Other more advanced sensors can obtain more accurate and sensitive displacement information, but the principle of interaction is the same.

When the video is captured by the intelligent mobile terminal, the smart mobile terminal can be obtained by turning on the mobile acceleration sensor that can sense the movement acceleration of the intelligent mobile terminal and the data collected by the acceleration sensor and the time recorded by the intelligent mobile terminal. Displacement information during shooting; when the smart mobile terminal plays the aforementioned video file, the mobile acceleration sensor that can sense the moving acceleration of the intelligent mobile terminal, the data collected by the moving acceleration sensor, and the intelligent movement are turned on again. The time recorded by the terminal obtains the displacement during the viewing process of the smart mobile terminal.

As shown in Figure 1, taking a smartphone as an example, the motion acceleration in the x, y, and z directions is periodically collected, wherein the z value reflects the direction of motion perpendicular to the plane of the smartphone screen, which can be ignored, and x and y indicate horizontal and vertical directions. The acceleration is moved, and x and y can be understood as the coordinate decomposition of the oblique motion. The initial velocity is 0, the displacement distance is 0, the data acquisition period is ti, and the instantaneous acceleration is a _i (this acceleration has been removed). Gravitational speed

Displacement

The above displacement, velocity and acceleration are all vectors, that is, the angle and distance information are included, and the moving distance can be a curve. See S in Fig. 2, we can simplify it to a straight line vector, see the displacement vector in the coordinates in Fig. 3. S1, so just store a point of information. Here we set the angle of vector S1 to alpha and length to d. On the line from the origin to S1, we uniformly take points s0, s1, s2, ..., sn, as shown in Figure 2.a. Vector S1".

[Detecting displacement information by video image]

In practical applications, the displacement accuracy detected by the moving acceleration sensor is very low, and only the approximate motion direction and displacement can be judged. In order to improve the accuracy, the image information collected by the camera can be analyzed for auxiliary processing. That is, when the video is captured by the smart mobile terminal, the direction and relative distance of the displacement or/and the rotation information during the shooting process are detected by the video image of the video file by the frame, and then the data collected by the acceleration sensor and the intelligent movement are detected. The time recorded by the terminal obtains the displacement or/and rotation information of the smart mobile terminal during the shooting process; when the smart mobile terminal plays the aforementioned video file, the front camera of the smart mobile terminal is turned on, and the front picture is taken, also by the frame pair The front picture detects the displacement of the bit view process and/or the direction and relative distance of the rotation information, and then obtains the displacement of the smart mobile terminal during the viewing process by the data collected by the acceleration sensor and the time recorded by the intelligent mobile terminal. And rotate the information.

Similarly, in the case of a mobile phone, when the mobile phone is shooting a video on the mobile, the direction and relative distance of the displacement can be detected by the frame according to the frame. As shown in Fig. 4, although we cannot obtain the precise moving distance, we can obtain the relative displacement. Size does not care about the distance of the scene. Similarly, when the video is playing, we open the front camera at the same time, take the front picture, and detect the face. If the detected face and background are removed, the relative displacement information can be obtained in the same way, as shown in Figure 5. At this time, the played video is displayed. For the convenience of explanation, the information displayed by the camera is displayed in the figure. The face is used as the positioning reference, and is not used as the information for judging the displacement. The front camera collects the video to judge the displacement, and the non-display video. . Although the background image captured by the front camera is different from the scene of the video being played, the displacement speed and distance error may be caused, but this does not affect the processing speed of the system in the same environment. If the face is not detected, the displacement is directly judged by the entire video frame; if all the faces are detected without the background image, the playback process is not performed or some interesting prompts are provided, for example, the screen can directly display the front camera collection. Picture.

[Detecting Rotation Information by Gyro]

In view of the current industry level of technology, it is difficult to obtain accurate mobile phone displacement information, even if the displacement is detected by the image, there is a large amount of calculation, and it is relatively easy to obtain accurate information on the rotation angle of the mobile phone, so we can drive the video by the rotation angle. It's easier to implement this immersive experience. That is, when the video is captured by the intelligent mobile terminal, the smart mobile terminal can be obtained by turning on the gyroscope which can be used to sense the rotational acceleration of the intelligent mobile terminal, the data collected by the gyroscope, and the time recorded by the intelligent mobile terminal. Rotation information during the shooting process; when the smart video terminal plays the aforementioned video file, the gyroscope which is built in the mobile terminal and can sense the rotational acceleration of the intelligent mobile terminal, the data collected by the gyroscope, and the intelligent mobile terminal record are turned on again. The time to get the rotation information during the viewing process of the smart mobile terminal.

Similarly, in the case of a mobile phone, when the video viewer picks up the mobile phone and rotates the body as the axis, the gyroscope can obtain the rotation angle of the mobile phone. For the convenience of description, we define the angle values acquired by the mobile phone at different times a0, a1, a2, ... an. As shown in Figure 6, the phone is picked up and the an angle is rotated with the body as the axis. In the three-dimensional space, the angle can be projected into the planes of x, y, and z. According to the current posture of the mobile phone, we only select the angular component of the x or y direction. The change value is taken as a discrete sample of a0, a1, a2, ... an.

In the above two ways, the description is based on displacement or rotation playback, namely:

When playing a video, replace the time variable t of the video with the displacement variable s, that is, display the frames F0, F1, F2, ..., Fn from the time point of t0, t1, t2, ..., tn. The transition to display each frame at each spatial displacement point s0, s1, s2, ..., sn. As shown in Figure 7, it is systematically described as F _n =f(t _n )=f'(s _n ), where F _n is the current playback frame, t _n is a certain point in time, and s _n is a certain spatial point, f and f' is a function that maps time and space to a playback frame. Note that the time and space are continuous, the playback frame is discrete, and the subscript n should be used to represent a continuous to discrete meaningful range of values. In fact, the sampling of the acceleration state information by the mobile phone is also discrete, and some displacement points may not be collected when the moving speed is fast. The value of the displacement needs to be matched with the frame to ensure that the entire video frame sequence is played when S1 is shifted. If the instantaneous displacement ds is detected during playback, and the video has a total of m frames, the video to be played is m*ds/ S1 frame, taking the integer part, leaving the decimal part to the back. It can be seen that each time the displacement sensing sample may correspond to the number of frames that need to be played may be less than 1, or may be large, such as tens of frames.

Similarly, when playing a video, the time variable t of the video is replaced by the angle rotation variable a, that is, the original video is displayed by the time points of t0, t1, t2, ..., tn for each frame F0, F1, F2. .., Fn, is converted to display each frame at each of the rotation angle points a0, a1, a2, ..., an. As shown in Figure 7, the logic of the time function of the playback frame mapped to the angle function is consistent.

In order to improve the smoothness during playback, we apply a low-pass filter to calculate the acceleration of the displacement variable. The expression is beta*a _i +(1-beta)a _i-1 , beta is greater than 0 and less than 1, and the smaller the beta is, the smaller the filter is. The stronger the value, the recommended value is 0.3. It is difficult for the user to move at a constant speed, and even there is jitter when the playback is played. Therefore, a buffer Jitter buffer is set, and the buffer size is recommended to be 10 to 20 frames. The buffer inputs the sequence of the video file to be played. The number and play timestamp, after smoothing the timestamp, the output plays the aforementioned video file, thereby eliminating jitter.

Further, the deviation of the moving speed should be tolerated, that is, as long as the displacement or/and the rotation information during the viewing and the displacement or/and the rotation information during the shooting are within the preset tolerance range, the viewing process is considered The displacement or/and rotation information in the match matches the displacement or/and rotation information during the shooting. For example, if the speed of movement during playback is within v_theta (recommended value is 50%), it can be played at the original rate. The motion beyond the tolerance range is fast forward or slow. If the displacement speed is too fast, consider skipping the frame. Play the video. In order to improve usability, we allow some deviation between the viewer and the recorder's displacement; as long as the displacement angle of the two can match within 45 degrees, it can respond. As shown in Fig. 8, the 45° range of the same displacement direction is the play area, the opposite direction is 45 degrees for the reverse area, and the other areas are the non-response area; we call this 45 degree range the fault tolerance angle r_theta, we can Adjust the r_theta angle size to control the matching accuracy of the two.

If the angle rotation is used to drive the video, starting from the ease of use, it is possible to consider only the rotation angles of the two directions of the left and right rotation, that is, the same direction rotation is normal playback, and the reverse rotation is reverse rotation.

Different from the usual playing mode, this method needs to watch the video by the user moving or/and rotating the mobile phone, and it is important to provide an intuitive and simple interactive prompt. When the smart mobile terminal plays the foregoing video file, the video file playing interface prompts the displacement or/and rotation information of the smart mobile terminal during the shooting process, and the viewer moves according to the displacement or/and rotation information prompted by the video file playing interface or Rotate the smart mobile terminal. Similarly, taking a mobile phone as an example, referring to FIG. 9, the arrow on the screen of the mobile phone not only indicates the direction of displacement or/and rotation, but also reflects the progress of the current video playback. Figure 10 is another design. The orientation of the sphere in the circle indicates the direction of displacement or / and rotation. If the ball is placed in the center of the circle when displaced, the movement or / and the rotation speed is just right, if moving or / and rotating Too fast to make the video fast forward, the ball will be in the opposite direction; the thick line of the outer circle indicates the progress of the video playback. It should be understood that these interaction designs mainly need to reflect two aspects of information, one is displacement or / and the direction of rotation, and the other is the progress of playback;

Of course, while playing the video screen at the same time, the audio should also be played at the same time. Since the speed of the viewer and the recorder's displacement (rotation) may not be consistent, the played audio needs to be processed. There are two strategies, one is the shifting constant shift, and the other is the direct shifting tone; the former guarantees the authenticity of the audio information, and the speed of the latter is more variable and more interesting. We can choose different strategies according to actual needs.

In summary, the innovation of the present invention is:

a. In addition to saving audio and video information, the video also saves the displacement (rotation) information, allowing the viewer to experience the video in another new media dimension;

b. The new way of playing video, instead of the traditional time-based variable to display the video picture by frame, but according to the displacement (rotation) variable to display the picture by frame;

c. It can replace the panoramic photo shooting and browsing experience, reduce the photographer's stability requirements, shoot the panoramic angle arbitrarily large (a 360 can support), the shooting direction is arbitrary (up and down, left and right, bevel can be), the viewer's The viewing experience is also richer and more interesting.
