Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the application provides a display method of a video acquisition position, which can be applied to display equipment. The display device may include: a display screen. Optionally, the display device may be a mobile phone, a tablet, a laptop, a desktop computer, or a television, for example, the display device may be a desktop computer. Referring to fig. 1, the method may include:
step 101, acquiring a video to be played and a plurality of acquisition positions where a camera is located in the process of acquiring the video.

Or, the display device may include a camera, and the display device may start the camera to acquire a video and obtain a plurality of acquisition positions where the camera is located in the process of acquiring the video.
The video may include a plurality of video frames, and frame capture time of any two of the plurality of video frames is different. The frame acquisition time is the acquisition time of the video frame. Any two of the plurality of collecting positions have different position collecting time, and the position collecting time is the collecting time of the collecting position.
And 102, responding to a playing instruction aiming at the video, and playing the video in a first display area of the display screen.
The display device may receive a play instruction for a video and may play the video in a first display area of the display screen in response to the play instruction for the video.
And 103, displaying the map in a second display area of the display screen in the process of playing the video, and updating the position of the position mark point in the map based on the plurality of acquisition positions.
Wherein the second display area is different from the first display area. For example, the first display area may be a partial display area on the left side of the display screen and the second display area may be a partial display area on the right side of the display screen.
When the display device plays a first video frame of a plurality of video frames included in the video in the first display area, the position mark point in the second display area may be located at the first capture position. The first video frame is any video frame in the video, and the first capture position may be a capture position of which the position capture time is closest to the frame capture time of the first video frame among the plurality of capture positions.
To sum up, the embodiment of the present application provides a method for displaying a video capture position, where in a process of playing a video in a first display area of a display screen, a display device may display a map in a second display area of the display screen, and synchronously update positions of position mark points in the map based on multiple capture positions where a camera is located when capturing the video. Because the display equipment can synchronously display the acquisition position of the camera when the video is acquired in the map in the process of playing the video, the flexibility of the acquisition position of the video is improved.
In the embodiment of the application, the display device may receive a video to be played, which is sent by the acquisition device, and a plurality of acquisition positions where a camera of the acquisition device is located in the process of acquiring the video. Or, the display device may include a camera, and the display device may directly acquire the video to be played through the camera, and may acquire a plurality of acquisition positions where the camera is located in the process of acquiring the video.
In the following embodiments, a video to be played and a plurality of acquisition positions where the camera is located are acquired by a display device are taken as examples, and a display method of the acquisition positions of the video provided by the embodiments of the present application is exemplarily described. The method can be applied to a display device, and the display device comprises a camera and a display screen.
Referring to fig. 2, the method may include:
step 201, responding to a video acquisition instruction, and starting a camera to acquire a video.
The user may touch a video recording control of the display device. The display device may receive a video capture instruction triggered by a user for the video recording control, and may activate the camera in response to the video capture instruction. The camera can periodically collect video frames according to a first sampling period after being started. Accordingly, the display device can acquire a video including a plurality of video frames acquired by the camera.
Each video frame corresponds to one frame acquisition time, and the frame acquisition times of any two video frames are different. The moment when the display device collects one video frame every other first sampling period is the frame collecting moment of the video frame, namely the interval of the frame collecting moments of two adjacent video frames is the first sampling period.
Optionally, the video recording control may be a physical button or a virtual control.
Step 202, in the process of collecting the video, collecting the collecting positions where the cameras are located to obtain a plurality of collecting positions.
The display equipment is internally provided with the position acquisition assembly, and the display equipment can control the position acquisition assembly to periodically acquire the position of the camera according to the second sampling period in the process of acquiring videos by the camera, so that a plurality of acquisition positions are obtained. Each acquisition position corresponds to one position acquisition time, and the position acquisition times of any two acquisition positions are different. The moment when the display device collects one collection position every second sampling period is the position collection moment of the collection position, namely the position collection moments of two adjacent collection positions are the second sampling period.
The second acquisition period may be greater than or equal to the first acquisition period. That is, the interval between the position acquisition time of two adjacent acquisition positions may be greater than or equal to the frame acquisition time of two adjacent video frames. Accordingly, the number of capture positions acquired by the display device in a unit time may be less than or equal to the number of video frames acquired in the unit time.
For example, the second sampling period is greater than the first acquisition period. The first sampling period may be on the order of milliseconds and the second acquisition period may be on the order of seconds.
Optionally, the position acquisition assembly may include: a Global Positioning System (GPS) component, a base station locating component, and a wireless locating component (e.g., a bluetooth locating component). Each acquisition location at which a camera is located may refer to the geographic coordinates at which the camera is located, which may include longitude and latitude.
Optionally, the display device may be moved during the process of capturing the video. Accordingly, at least two acquisition positions of the plurality of acquisition positions may be different.
In the embodiment of the present application, in the process of capturing a video, after the first capturing position is captured, that is, after the first capturing position is captured to the capturing position at the earliest position capturing time (that is, the second capturing position described below), the display device may record and store the first corresponding relationship between the second capturing position and the video frame (that is, the second video frame described below) captured at the position capturing time of the second capturing position. That is, the frame capture time of the second video frame is the same as the position capture time of the second capture position.
Optionally, the video includes each video frame having an index, and the indexes of any two video frames are different. The first correspondence may record a correspondence of the second capture position to an index of the second video frame.
Alternatively, the display device may record the first correspondence in the target location file. In addition, in the process of collecting the collection position where the camera is located, the display device may record each acquired collection position in the target position file.
After the video and the collection of the collection positions are completed, the display device can also record a second corresponding relationship between the video and a target position file corresponding to the video, so that after a playing instruction for the video is received subsequently, the target position file corresponding to the video can be determined based on the second corresponding relationship, and a plurality of collection positions where the camera collects the video are read from the target position file.
And step 203, responding to a playing instruction aiming at the video, and playing the video in a first display area of the display screen.
The user can touch the video playing control of the display device. Accordingly, the display device can receive a playing instruction for the video triggered by the user for the video playing control, and can play the video in the first display area of the display screen thereof in response to the playing instruction.
As an alternative implementation, the play instruction may be used to instruct the display device to play the video from the beginning. Accordingly, the display device may play the video starting from a first video frame in the video in the first display area of the display screen in response to a play instruction for the video.
Or, if the display device records the first corresponding relationship between the second capture position and the second video frame, the display device may respond to the play instruction for the video, and start playing the video from the second video frame corresponding to the second capture position in the first display area of the display screen.
In the process of acquiring the video, the display device may not acquire the acquisition position of the camera after acquiring the first video frame in the video. Therefore, after receiving the playing instruction for the video, the display device can play the video from the second video frame, so that the second acquisition position corresponding to the second video frame can be synchronously displayed in the second display area. Thereby, a synchronized display of the video and the capturing position can be ensured.
As another alternative implementation, the play instruction may be used to instruct the display device to play the video starting from the middle video frame of the video. Accordingly, the display device may play the video starting from the intermediate video frame in response to a play instruction for the video.
And 204, in the process of playing the video, displaying a map in a second display area of the display screen, and updating the positions of the position mark points in the map based on the plurality of acquisition positions.
Wherein the second display area is different from the first display area. For example, the first display area may be a partial display area on the left side of the display screen, and the second display area may be a partial display area on the right side of the display screen. Alternatively, the first display region may be a partial display region on an upper side of the display screen, and the second display region may be a partial display region on a lower side of the display screen.
In this embodiment, when the display device plays the first video frame of the video in the first display area, the position mark point in the map may be located at the first capture position. The first video frame is any video frame in the video, and the first capture position may be a capture position of which the position capture time is closest to the frame capture time of the first video frame among the plurality of capture positions. For example, the first capture location may be a capture location of the plurality of capture locations having a same location capture time as a frame capture time of the first video frame.
That is, when the display device displays any video frame included in the video in the first display area of the display screen, the display device can display the capture position (i.e., the position of the position mark point on the map) where the camera captures the any video frame in the map in the second display area of the display screen. Therefore, the acquisition position of the video can be synchronously displayed in the process of playing the video.
The display equipment can synchronously display the acquisition position of the video acquired by the camera in the map, so that the flexibility of the acquisition position of the video is improved. In addition, other geographic elements are also displayed in the map, so that the acquisition position is displayed in the map, and the geographic position relation between the acquisition position and the other geographic elements can be displayed, so that a user can visually know the acquisition position where the camera acquires the video, and the user experience is effectively improved.
As an optional implementation manner, for a scene in which the play instruction is used to instruct the display device to play the video from the beginning, after receiving the play instruction for the video, the display device may display the position mark point at the second capture position in the map.
In this implementation, the display device may display the location marker point at the second capture location of the map upon detecting that the first video frame of the video is played. Or, if the display device records the first corresponding relationship between the second capture position and the second video frame, the display device may display the position mark point at the second capture position of the map when it is detected that the second video frame is played.
After the display device displays the position marker at the second acquisition position of the map, the position of the position marker point in the map may be updated based on at least two acquisition positions of the plurality of acquisition positions that are located after the second acquisition position.
Optionally, when detecting that the second video frame is played, the display device may determine, based on a second correspondence recorded in advance, a target location file corresponding to the video, and read the second capture location and the capture location located after the second capture location from the target location file.
As another optional implementation manner, for a scene in which the play instruction is used to instruct the display device to start playing the video from the middle video frame of the video, if the display device does not receive the pause instruction for the video before receiving the play instruction, the display device may display the position mark point at the target capture position in the map. The display device may then update the position of the position marker point in the map based on at least two of the plurality of acquisition positions that are located after the target acquisition position.
The interval between the position acquisition time of the target acquisition position and the position acquisition time of the second position is closest to the interval between the frame acquisition time of the second video frame and the frame acquisition time of the intermediate video frame. For example, the interval between the position capture time of the target capture position and the position capture time of the second position may be equal to the interval between the frame capture time of the second video frame and the frame capture time of the intermediate video frame.
Optionally, the display device may determine, in response to a play instruction for the video, a target location file corresponding to the video based on the second correspondence, and read the second capture location from the target location file. The display device may then determine a target position capture moment of the target capture position based on an interval of a frame capture moment of the second video frame and a frame capture moment of the intermediate video frame, and a position capture moment of the second position. Then, the display device may read the acquisition position of the target position acquisition time in the target position file and the acquisition position located behind the target acquisition position.
In the embodiment of the application, in the process of playing the video, the display device may obtain one collection position every other update period according to the sequence of the position collection times of the plurality of collection positions, and display the position mark point at the collection position in the map, so as to update the position of the position mark point in the map. The update period may be greater than or equal to the interval between the position acquisition times of two adjacent acquisition positions and greater than the interval between the frame acquisition times of two adjacent videos.
If the update period is equal to the interval of the position acquisition time, in the process of playing the video, the display device may sequentially acquire each acquisition position according to the sequence of the position acquisition times of the plurality of acquisition positions, and display the position mark point at the acquisition position in the map. Therefore, the continuous updating and the accurate updating of the position mark point in the map can be ensured, and the effective synchronization of the position mark point displayed in the map and the video frame currently displayed in the first display area is further ensured.
For example, it is assumed that the second sampling period of the display device is 0.5 seconds(s), that is, the display device can acquire the capture position where one camera is located when capturing the video every 0.5s, and the obtained multiple capture positions include: position a, position b, position c, position d, position e, position f and position g. If the update cycle of the position mark point in the map is the interval of the position acquisition time of two adjacent acquisition positions, namely the update cycle is 0.5s, and the display equipment starts to play the video from the beginning. The display device may display the position mark point at the position a in the map after receiving the play instruction for the video, and then the display device may display the position mark point at the position b, the position c, the position d, the position e, the position f and the position g in sequence.
Since the first sampling period of a video frame is typically smaller than the second sampling period of the acquisition position, there are situations where the camera acquires multiple video frames at the same acquisition position. In this case, if the interval between the position acquisition times of two adjacent acquisition positions is used as the update cycle, the position mark point may be displayed at the same acquisition position in the map for multiple times, so that the position change of the position mark point in the map is not obvious, and the power consumption of the display device is increased. Therefore, in the embodiment of the present application, the update period of the position mark point may be greater than the interval of the position acquisition time. Therefore, on the premise of ensuring the accurate updating of the position mark point, the power consumption of the display equipment is prevented from being increased.
It can be understood that, for a scene in which the update period of the position marker is greater than the interval of the position acquisition time, the display device reads only a part of the acquisition positions in the target position file and displays the position marker at the read part of the acquisition positions.
For example, suppose that the interval between the position acquisition time of two adjacent acquisition positions is 0.5s, and the update cycle of the position mark point in the map is 1 s. The multiple acquisition positions acquired by the display device include: position a, position b, position c, position d, position e, position f and position g. The display device may display the position mark point at the position a in the map after receiving the play instruction for the video, and then the display device may display the position mark point at the position c, the position e, and the position g in sequence.
In the embodiment of the application, in the process of playing the video, the display device may sequentially read the plurality of acquisition positions from the target position file according to the sequence of the position acquisition times of the plurality of positions. And then, the display equipment can call a third-party digital map interface to display the map in the second display area, and the position of the position mark point in the map is updated based on the read acquisition position.
As a possible example, the map may also display a trajectory line formed by connecting a plurality of acquisition positions in order of the position acquisition times. The display device may update the position of the position marker point on the trajectory line based on the plurality of acquisition positions.
Illustratively, referring to fig. 3, the display screen includes a first display area a and a second display area B. As can be seen from fig. 3, the first display area a is located on the left side of the display screen and the second display area B is located on the right side of the display screen.
Assuming that the display device acquires a plurality of acquisition positions includes: the positions a to i are sequentially increased, and the position acquisition time from the position a to the position i is sequentially increased. The display device can display a trajectory line S formed by connecting the position a to the position i in this order in the map displayed in the second display area B.
The position marker point Z is currently located at position c. And if the next acquisition position acquired by the display equipment is the position d, the display equipment can update the position mark point Z to the position d. As can be seen from fig. 3, both position c and position d are located on the trajectory line S.
In addition, as can be seen from fig. 3, a control 01 for adjusting and displaying the playing progress is also displayed in the first display area a, and the current playing progress of the video is "0: 01:54/0:19: 54".
