Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of a method for delivering a business object according to an embodiment of the present invention is shown.
The method for releasing the business object in the embodiment comprises the following steps:
step S102: and acquiring a service object releasing template corresponding to the funnel screen position according to the requirement of releasing the service object at the funnel screen position of the sports field.
Although the service objects are delivered in the funnel screen in the embodiment, since the positions of the funnel screen in the recorded scenes of the stadium recorded by the camera in the stadium are different, the angles of the camera and the depths of field of the camera lens may be different, one or more service object delivery templates corresponding to the positions of the funnel screen need to be prepared in advance.
For example: when the video camera of the host position is adopted to record the sports field, the funnel screen in the recorded audio and video in the sports field displays each screen facing the host position. The corresponding service object delivery template is a set funnel screen and corresponding screens should be set and displayed. When the video camera at the side machine position of the sports field is used for recording the sports field, the funnel screen in the recorded audio and video in the sports field displays each screen facing the side machine position, and the corresponding service object delivery module also needs to be provided with the funnel screen displaying the corresponding screen. Since the positions of the main machine position and the side machine position are different, obviously, the positions of the screens facing the main machine position and the side machine position in the funnel screen are also different, so that one or more service object release templates corresponding to the positions of the funnel screen need to be manufactured in advance.
Similarly, when the video cameras of other machine positions are used for recording, the corresponding release templates are diversified, so that the service object release templates corresponding to the funnel screen positions need to be acquired according to the requirements of releasing the service objects at the funnel screen positions of the sports field.
Step S104: and selecting a camera for recording the audio and video data at the position of the funnel screen, and adjusting the angle of the camera by using the adjustment parameters.
A plurality of cameras are arranged on the scene of the sports field, and pictures displayed by the audio and video data of the sports field recorded by the cameras with different machine positions are different.
For example: when audio and video data, namely sound and pictures, need to be obtained through overhead shooting, a flying cat machine position capable of being arranged on a sports field site needs to be selected, and when the audio and video data need to be obtained through panoramic shooting, a main machine position needs to be selected to record the sports field.
The adjustment parameters may be preset, and after the service object launching template at a certain funnel screen position is acquired in step S102, the camera at the corresponding machine position and the adjustment parameters for adjusting the angle of the camera need to be selected to adjust the angle of the selected camera, so that the funnel screen in the audio and video data recorded by the adjusted camera can be matched with the funnel screen in the acquired launching template.
Step S106: and acquiring real-time audio and video data of the sports field by using the camera with the angle adjusted, and playing and displaying the real-time audio and video data.
The acquired real-time audio and video data comprise real-time audio and video data of the funnel screen position. The real-time audio and video data are video data and audio data in a sports field acquired in real time, namely related videos of the sports field and sounds corresponding to the videos.
Step S108: and matching and positioning the funnel screen of the playing and displaying sports field and the funnel screen in the service object releasing template according to the acquired real-time audio and video data of the funnel screen and the service object releasing template so as to enable the two funnel screens to be completely overlapped.
It should be noted that, when the funnel screen of the playing and displaying sports field and the funnel screen in the service object delivery template are positioned in a matching manner, the two funnel screens can be completely overlapped by manually fine-tuning the angle of the camera, and the matching positioning can be performed by related adjusting equipment according to a set positioning method, for example: the four-point positioning method is adopted for matching and positioning, and of course, other positioning methods can be set for matching and positioning, for example: six-point positioning method. In practical implementation, a specific matching positioning scheme is set by a person skilled in the art according to practical requirements, and the present application is not limited to this.
Step S110: and putting the service objects to be put in the superposed funnel screens, so that the playing and displaying of the service objects are carried out at the positions of the funnel screens of the sports stadium where the playing and displaying are carried out while the real-time audio and video data of the sports stadium are played and displayed.
The delivered business object may be an advertisement. The playing presentation of the business object may be played in a static form, for example: displaying characters and/or images corresponding to the business objects in each superposed screen of the funnel screen; it can also be played in a dynamic form, such as: and playing the characters and/or images corresponding to the business objects in each superposed screen of the funnel screen in a form of rotating animation.
By the method for releasing the business object provided by the embodiment, the business object is released at the playing position of the funnel screen of the sports field while the real-time audio and video data of the sports event is played, and the business object is released at a low cost and can save the propaganda cost because the releasing of the business object does not influence the playing progress of the event and does not occupy the sports field. In addition, according to the method for releasing the business object provided by this embodiment, the business object is embedded in the audio/video data played in real time when being released, so that the audience can acquire the information of the released business object while watching the game, the audience watching the game is not influenced, and the audience watching the game can also watch the released business object, and therefore, the releasing mode is easy to receive, and the audience watching the game can watch the released business object, so that the method has a good propaganda effect. Therefore, compared with the existing method for releasing the business object, the method for releasing the business object provided by the embodiment saves the propaganda cost and has a good propaganda effect.
Example two
Referring to fig. 2, a flowchart illustrating steps of a method for delivering a business object according to a second embodiment of the present invention is shown.
The method for releasing the business object in the embodiment specifically comprises the following steps:
step S202: the releasing system obtains a business object releasing template corresponding to the funnel screen position according to the requirement of releasing the business object at the funnel screen position of the sports field.
The sports field can be any field on which a funnel screen can be installed over the field. In the present embodiment, a basketball game field is described as an example. Wherein the delivery system may be a workstation in a relay truck. And information interaction is carried out between the workstation in the relay station and the cradle head for controlling the camera. For example: the workstation in the rebroadcasting car can adjust the angle of the camera through the cradle head, and the workstation in the rebroadcasting car can also receive real-time audio and video data uploaded by the camera. And the workstation in the rebroadcasting vehicle can rebroadcast the acquired audio and video data on terminals such as a television, a computer and the like.
When the business objects are released, although the business objects are released in the funnel screen, different positions of the funnel screen correspond to different business object releasing templates. For example: the funnel screen in the audio and video data recorded by the camera may be located at the center position, the right position, the left position, the front position, the rear position, etc. of the whole recorded video picture. In addition, the sizes of the funnel screens displayed in the recorded audio and video data are different, and some funnel screens may be enlarged funnel screens, and some funnel screens may be reduced funnel screens. It can be seen that the positions of the funnel screens in the recorded audio and video data are different. The position of the funnel screen in the audio and video data is determined by the position of a camera for recording the audio and video data and the angle of the camera.
The diversification of the positions of the funnel screens in the recorded audio and video data determines the diversification of the service object release templates. Of course, there may be a corresponding relationship between the camera position and the camera angle and the release template of the business object.
Step S204: and the delivery system selects a camera for recording the audio and video data at the position of the funnel screen.
The releasing system is stored with business object releasing templates of various funnel screen positions in advance, and also stored with camera positions of the cameras corresponding to the releasing templates and adjusting parameters for adjusting the cameras.
When the camera for recording the audio and video data at the position of the funnel screen is selected, the camera positioned at the main machine position can be selected, the lens of the selected camera is adjusted into the foreground to record the audio and video data at the position of the funnel screen, and the audio and video data is recorded by adopting the full machine position; or selecting a camera positioned at a side machine position of the sports field, adjusting the lens of the selected camera into the foreground to record audio and video data at the funnel screen position, and recording the audio and video data by adopting a large side whole machine position. A mode for acquiring funnel screen audio and video data with harmonious display proportion in a screen comprises the following steps: the funnel screen of the sports field is hung above the sports field through the traction of the steel rope, the height of the funnel screen can be adjusted according to requirements, and the funnel screen can be directly fixed above the sports field at a fixed height and is more flexible. The proportion of the funnel screen in the recorded audio and video data in the screen can be more coordinated through adjustment, the spatial layout of the displayed picture is more reasonable, and the texture effect is real.
Step S206: and the launching system acquires the selected adjusting parameters of the camera and adjusts the angle of the camera according to the adjusting parameters.
Wherein, the adjustment parameter includes: at least one group of parameters of sensor delay parameters, camera position parameters, lens basic parameters, rotating shaft parameters, anchor point parameters and zooming parameters of the camera.
When the camera is adjusted according to the sensor delay parameters of the camera, the sensor delay parameters of the camera are obtained, the sensor of the camera is adjusted according to the sensor delay parameters, and real-time audio and video data recorded by the camera is played and displayed after the time length indicated by the sensor delay parameters is prolonged. For example: the delay parameter is adjusted to 85ms, namely 85ms, and the recorded audio and video data and the real scene in the sports field can be synchronized by adjusting the delay parameter.
When the angle of the camera is adjusted according to the position parameters of the camera, the position parameters of the camera are obtained, and at least one of the transverse coordinate, the longitudinal coordinate and the front and back coordinates of the camera is adjusted according to the position parameters in the position parameters; adjusting at least one of a horizontal and remote fine adjustment angle, a pitching fine adjustment angle and a side rolling fine adjustment angle of the camera according to camera rotation parameters in the machine position parameters; and adjusting the transverse side length and the longitudinal side length of the imaging focus rectangle of the camera according to the positioning parameters in the machine position parameters. Wherein, the position parameter includes: at least one of a position parameter, a camera rotation parameter, and a positioning parameter.
For example, the lateral coordinate of the camera can be adjusted to-2081.10 mm, namely-2081.10 mm, the longitudinal coordinate is-761.80 mm, the fore-and-aft coordinate is-7563.79 mm, the panning fine adjustment angle is 1.354 degrees, the pitching fine adjustment angle is 0.062 degrees, and the rolling fine adjustment angle is 0.376 degrees. And because the horizontal side length of the rectangle calibrated in the positioning parameters is 4880mm, and the longitudinal side length of the rectangle is 1840mm, the horizontal side length and the longitudinal side length of the imaging focus rectangle of the camera are adjusted according to the calibrated rectangle parameters, the horizontal actual side length of the rectangle is adjusted to 4880mm, and the longitudinal actual side length is adjusted to 1840 mm. The specific object in the recorded sports field can be calibrated by setting the calibration rectangle size, for example, the funnel screen in the sports field is calibrated, and the funnel screen imaging is calibrated in the rectangle, so that the funnel screen imaging can be displayed in the calibrated rectangle in the audio and video recorded by the camera, and subsequent matching and positioning are facilitated.
The method comprises the steps of acquiring basic lens parameters of the camera when adjusting the angle of the camera according to the basic lens parameters of the camera, and adjusting at least one of the maximum pulse value of a zoom encoder of the lens of the camera on the lens, the width of the angular field of view of the lens of the camera, the maximum zoom multiple of the lens of the camera, the focus anchor point of the lens of the camera and the focus change rate of the lens of the camera according to the basic lens parameters.
Wherein, the basic lens parameters include: at least one of a maximum zoom sensor value of the lens, an angular field width of the lens, a zoom multiple of the lens, a focus anchor point of the lens, and a focus change rate of the lens. For example, during adjustment, the camera is adjusted according to the acquired basic parameters of the lens to adjust the maximum pulse value of the lens to 75750, the angular field width of the lens to 64.50mm, the zoom factor of the lens to 18.00 times, and the focus anchor point and the focus change rate to 0.
When the angle of the camera is adjusted according to the rotating shaft parameters of the camera, the rotating shaft parameters of the camera are obtained, the rotating shaft of the camera is adjusted according to the rotating shaft parameters, the angular deviation occurring when the rotating shaft of the camera tracks and records audio and video data is corrected, the vertical distance from the center of the pitching shaft of the cloud deck where the camera is located to the central axis of the side face of the lens of the camera is adjusted, and the horizontal distance from the horizontal and remote shaft of the cloud deck to the optical core of the lens of the camera is adjusted.
Wherein, camera pivot parameter includes: and adjusting at least one of the pitching zero point deviation angle, the roll fine adjustment angle and the rotating shaft in the YZ direction of the camera.
In this embodiment, the pan tilt for controlling image capture is internally provided with a memory translation and pitch zero point, but there may be a slight angular deviation that cannot be guaranteed by quality control in the production, assembly, and adjustment of each pan tilt. When a sensor position for installing a camera is installed, a horizontal rotating shaft Y of the cloud deck is generally perpendicular to the ground through a level gauge on the cloud deck, a pitching rotating shaft X is parallel to the ground, and a lens optical axis Z of the camera is horizontal to the ground. However, during actual installation, the connecting assembly of the four parts of the pan/tilt head, the pan/tilt head shoe plate, the camera supporting plate and the camera may have a side rolling angle deviation. The angular offset which occurs when the rotating shaft of the camera tracks and records audio and video data can be corrected by finely adjusting the pitching zero point deviation angle and the side rolling fine adjustment angle of the camera in the rotating shaft parameters of the camera. The reference values for the typical fine adjustment are a pitch zero offset angle of 1.00 degrees and a roll fine adjustment angle of 0.10 degrees.
And for the YZ direction rotating shaft adjustment, the Y direction rotating shaft is the vertical distance from the pitching shaft X of the tripod head to the optical axis of the lens of the camera, so the vertical distance from the center of the pitching shaft of the tripod head where the camera is located to the central axis of the side surface of the lens of the camera can be adjusted by adjusting the Y direction rotating shaft. And the Z-direction rotating shaft is the horizontal distance from the horizontal remote axis Y of the holder to the optical core of the camera lens, so the horizontal distance from the horizontal remote axis Y of the holder to the optical core of the camera lens can be adjusted by adjusting the Z-direction rotating shaft. For example, the adjustment value of the rotation axis in the Y direction can be set to 180.0mm, and the adjustment value of the rotation axis in the X direction can be set to-215.5 mm.
The method comprises the steps of obtaining anchor point parameters of a camera when adjusting the angle of the camera according to the anchor point parameters of the camera, adjusting a sensing pulse value of a zoom point of an anchor point of a lens of the camera according to the anchor point parameters, adjusting the size of an object image of the camera, setting an adjusting value for adjusting distortion when the object image is located at the edge of the lens of the camera, and performing self-calibration on the anchor point.
Wherein the anchor point parameters include: anchor point X, Y focal length adjustment, anchor point distortions 1, 2, anchor point zoom values, and whether anchor point self-calibration is performed. A variable focus point can be set in a zoom segment of the lens as an anchor point, the panning and tilting tracking effect in the zoom segment can be optimized by adjusting anchor point parameters, and the zoom tracking effect of the lens needs to be adjusted by taking the set anchor point as a reference point.
During specific adjustment, the drift of the object image when the lens is horizontally tilted is improved by adjusting the focal length adjustment value of the anchor point X, Y, but the size of the object image is changed at the same time; by adjusting anchor point distortions 1 and 2, the distortion of the object when the object is imaged at the lens edge of the camera can be adjusted; adjusting the sensing pulse value of the zoom point of the anchor point of the lens of the camera through the anchor point zoom value; the anchor point self-calibration criterion is that the anchor point self-calibration is completed by acquiring a plurality of groups of anchor point parameters at different positions of a calibration rectangle in a lens to calculate the anchor point focal length and distortion value.
When the angle of the camera is adjusted according to the zooming parameters of the camera, the zooming parameters of the camera are obtained, and the slope of a zooming reference curve, the imaging size of an object on 5 segmented adjusting points on the zooming reference curve, the imaging transverse offset and the longitudinal offset of the object on the 5 segmented adjusting points on the zooming reference curve and the deformation of the object on the edge of a lens when the object is imaged on the 5 segmented adjusting points on the zooming reference curve are adjusted according to the zooming parameters; wherein the zoom reference curve is a curve generated according to the field angle and the zoom value of the lens of the camera and used for describing the zoom effect of the object imaging and tracking lens.
It should be noted that, in practical implementation, the angle of the camera may be adjusted by adjusting a sensor delay parameter and/or a position parameter and/or a lens basic parameter and/or a rotation axis parameter and/or an anchor point parameter and/or a zoom parameter of the camera. The specific adjustment of the one or more sets of parameters is determined according to the specific parameters defined in the adjustment parameters. If only one set of parameters is defined in the obtained adjustment parameters, the adjustment of the camera angle can be completed by adjusting only one set of parameters, and if the six sets of parameters are defined in the obtained adjustment parameters, the adjustment of the camera angle can be completed by adjusting the six parameters. Of course, there are also cases where two, three, or four groups are defined, and this application does not specifically limit this.
Step S208: the throwing system acquires real-time audio and video data of the sports field by using the camera with the adjusted angle, and plays and displays the real-time audio and video data.
The acquired real-time audio and video data comprise real-time audio and video data of the funnel screen position.
Step S210: the throwing system sets a first positioning rectangle of the funnel screen of the sports field containing the playing and displaying in the acquired real-time audio and video data of the funnel screen.
The transverse side length and the longitudinal side length of the first positioning rectangle are the transverse side length and the longitudinal side length of the rectangle set in the positioning parameters in the adjustment parameters.
Step S212: and the delivery system sets a second positioning rectangle containing the middle circle in the service object delivery template according to the transverse side length and the longitudinal side length of the rectangle set in the positioning parameters in the adjustment parameters in the service object delivery template.
And positioning point marks are respectively arranged at four corners of the first positioning rectangle and the second positioning rectangle.
Step S214: the putting system enables the first positioning rectangle to be overlapped with the second positioning rectangle by adjusting each positioning point mark in the second positioning rectangle in the service object putting template, so that the two funnel screens are completely overlapped.
It should be noted that, in the above steps S210 to S214, a four-point positioning method is adopted to match and position the funnel screen of the playing and displaying sports field and the funnel screen in the business object launching template, so that the two funnel screens are completely overlapped.
The funnel screen of the sports competition field played and displayed by using the four-point positioning method and the funnel screen in the service object putting template are positioned in a matching way, and the method comprises the following steps:
determining a calibration rectangle, namely determining a rectangle set in the positioning parameters in the adjustment parameters: a rectangular plane which can be identified in a shot in a sports field is selected as a calibration rectangle for positioning a camera, the width and the height of the calibration rectangle are measured by taking millimeters as a unit, and four corner points of the calibration rectangle are used as positioning points. When the calibration rectangle for positioning is selected, the recognizable rectangle on the plane with the highest requirement on the tracking effect in the sports field is selected as the calibration rectangle, if no obvious actual rectangle corner point exists in the sports field, manual measurement is needed, and a marker needs to be placed, wherein the size of the marker is based on the fact that the marker can be obviously distinguished in a camera lens. Four angular points of the calibration rectangle are positioning points, and the specific arrangement of the four positioning points is as follows: and calibrating the point position of the lower left corner of the rectangle to locate the zero point of the coordinate. And after the calibration rectangle is determined, automatically calibrating a first calibration rectangle in the video recorded by the camera.
Four-point positioning: and (4) leading in a release template, and adding a positioning point, namely setting a second calibration rectangle in the release template. Clicking the mouse in the broadcast monitor marks four corner points of the calibration rectangle, which are in the order of left-down, left-up, right-up and right-down. In the actual implementation, two positioning methods are added in the release template, one method is that when the camera is adjusted, a left key is directly selected in a positioning parameter column of the camera to directly add points, the left key sequentially clicks the position of a live-action positioning point displayed in a broadcasting monitor, and a positioning point mark appears; and the other is that a right key is directly clicked at the position of the positioning point, the 'adding positioning point' is selected, and the positioning point mark appears. Clicking the right button on the anchor point label that has been added fine-tunes the anchor point's pixel position on the playout monitor by selecting "edit anchor point". In the four-point positioning method, four positioning points are in a group, the four positioning points are displayed in the same color on the mark, the 'playing monitor' is clicked by a right key after a group of marking points are marked, and the 'positioning by the last group of points' is selected to realize the positioning.
After the positioning is passed, the release template is seen to be basically consistent with the first calibration rectangle in the video and the reference entity. And displays the position parameters of the positioning coordinate zero point of the camera in the "camera position" and the "camera rotation".
The positions of the camera and the calibration rectangle and the angle of the camera facing the calibration rectangle have a certain influence on the positioning result. The ideal positioning environment is that the horizontal and horizontal sensing values and the pitching sensing values of the camera are zero, the camera is vertically opposite to the center of the calibration rectangle, and the larger the proportion of the calibration rectangle in the camera lens picture is, the better the calibration rectangle is. In practical situations, the camera position may be difficult to satisfy the above conditions. In consideration of the deviation of the electric actual dimension measurement and the deviation of the mark positioning point, the camera position parameter and the rotation parameter obtained by positioning also have deviation, and the camera position and rotation parameter can be adjusted by comparing the release template with the recorded object to correct the positioning result. In practical implementation, other positioning methods can be adopted to match and position the funnel screen of the playing and displaying sports field and the funnel screen in the service object releasing template. For example: the six-point positioning method is adjusted by workers.
Step S216: and the putting system puts the service objects to be put in the superposed funnel screens so as to play and show the service objects at the positions of the funnel screens of the sports stadium when playing and showing the real-time audio and video data of the sports stadium.
The putting system puts the business objects to be put in the overlapped funnel screens at any proper time. The release duration of each business object can be set by those skilled in the art according to actual situations.
The delivered business object can be an advertisement sign containing characters or images, and can also be a combined advertisement sign of the characters and the images.
The color of the released business object can also be set by the technicians in the field according to the actual situation, so as to realize the perfect combination of the released business object and the competition field.
When the business objects are put in each screen of the funnel screen, the advertisement signs can be set to be static, and the advertisement signs can also be set to be rotary animation to be put in each screen of the funnel screen.
