At present, the field commander in crowd performance commands the rehearsal mainly by the subjective feeling of the editors and lacks scientific and effective technical means, so that many problems in the rehearsal process are difficult to find, and the rehearsal efficiency is greatly influenced. According to the field rehearsal system provided by the embodiment of the invention, accurate reference data can be provided for field rehearsal by acquiring rehearsal data and comparing the rehearsal data with preview simulation data.
According to a specific implementation manner of the embodiment of the invention, the actor performance data acquisition module comprises video acquisition equipment, and the acquired actor live performance data comprises video data.
The rehearsal data collection device can be a variety of devices that can obtain real-time rehearsal data, such as a motion capture device, a GPS positioning device, and the like. The evaluation scheme using the motion capture device is relatively complex, has high cost, and is suitable for performance scenes with accurate requirements on actor actions. The embodiment of the invention adopts a computer vision-based method, and finishes the acquisition and comparison of actor live performance data based on video processing by shooting the video of the whole performance process during rehearsal and applying relevant algorithms such as video moving object identification, detection and tracking.
According to a specific implementation manner of the embodiment of the invention, the error analysis module comprises a motion track extraction unit, and motion track data of the actor is extracted from the actor live performance data.
For the field commander, it is most important to make the crowd perform as consistent as possible with the rehearsal simulation scheme through the field commander. Therefore, whether the actual performance of the crowd is consistent with the preview simulation scheme, the degree of the coincidence, and how the adjustment should be made are very important to the field commander. In the performance data collected on site, various types of data are included, such as stadiums, lights, props, and the like. Of these data, the most important data for measuring how well the crowd performance is consistent with the rehearsal simulation is the data containing the personnel, such as data related to the position and movement of the actors. As a specific implementation manner of the embodiment of the present invention, actor movement trajectory data is selected as main comparison data.
According to a specific implementation manner of the embodiment of the present invention, the motion trajectory extracting unit includes: a video clip selecting unit, an actor position acquiring unit, a static object position acquiring unit, and a relative position calculating unit, wherein,
the video clip selecting unit selects a video clip without lens motion, and extracts frame by frame to obtain a video key frame sequence;
the actor position acquisition unit identifies an actor target for each frame image of the key frame sequence to obtain two-dimensional position coordinates of actors in the key frame images;
the method comprises the steps that a static object position obtaining unit selects two static objects which are shared by video key frame images, and two-dimensional position coordinates of the two static objects in the key frame images are obtained;
the relative position calculation unit calculates a pixel distance R1 between the actor and one of the objects and an angle β between a line connecting the actor and the object and two stationary objects.
The following describes in detail a specific implementation of the above method for extracting actor motion trajectory data:
first, lens division
The workflow of shooting the rehearsal video shows that the rehearsal video is a section of complete performance video with a plurality of shots switched, and the switching among all the shots is abrupt. Gradual change is a frame with some transition effects during shot switching, so that different shots have smooth change effects, and the gradual change is generally edited during later editing of video production. The post-production of the video can be not considered for the rehearsal effect evaluation, and the lens switching of a plurality of cameras does not involve gradual change in the rehearsal shooting process.
Due to sudden change of scenes caused by shot switching, actor movement track data are extracted from the complete video, and videos shot by different shots need to be extracted respectively. It is therefore necessary to segment the complete video into a plurality of video segments such that each video segment contains no shot motion. After the video is segmented, a video segment without lens motion is selected, and a video key frame sequence is obtained by extracting frame by frame.
Second, target recognition
In the key frame sequence, the actor moves, so the position of the actor in each frame image changes, and a video moving object identification and tracking algorithm is required to be applied to obtain two-dimensional position coordinates of the actor in the image. Currently, commonly used moving target tracking algorithms can be classified into several categories, such as those based on contrast analysis, those based on matching algorithm, those based on motion detection, and the like. In addition, in recent years, deep learning methods such as OverFeat, R-CNN and YOLO have been developed rapidly, and new ideas are brought to solve the problems of detection and positioning of moving objects in video frames.
Objects identified by video moving object identification algorithms are often identified with a rectangular box. As the distance between the targets needs to be calculated, the center point or a certain corner point of the rectangular frame is selected to mark the targets.
Thirdly, calculating the position
Selecting two static objects which are shared by the video key frame images, and acquiring two-dimensional position coordinates of the two static objects in the key frame images;
the pixel distance R1 of the actor from one of the objects and the angle β between the line connecting the actor and the object and the two static objects are calculated.
During rehearsal, static objects in the performance environment correspond to the simulation data of the performance environment in the simulation system, are irrelevant to the movement of performers, and are kept fixed in position. Since the sequence of video frames selected for performance evaluation does not contain lens motion, the position coordinates of the static object in the sequence of video frames remain unchanged. The position of a static object in a frame of video can be manually calibrated and used throughout the sequence of video frames. The shape characteristic information of the static object is rich, and the corner characteristic is obvious, so the characteristic points of the static object can be extracted through a characteristic extraction algorithm to obtain the two-dimensional position coordinates of the static object.
After two-dimensional position coordinates of the two static objects and the actor are obtained respectively, the pixel distance R1 between the actor and one of the objects and the included angle β between the connection line between the actor and the object and the connection line between the actor and the two static objects can be calculated, that is, the positions of the actor relative to the two static objects are obtained.
According to a specific implementation of an embodiment of the invention,
the sparing data comparison module receives the pixel distance R1 and the included angle β corresponding to each frame of image from the sparing data display module;
obtaining the proportional relation between the video frame and the preview simulation data according to the pixel distance of the two static objects in the video frame and the distance of the two static objects in the preview simulation data;
obtaining a distance R1' in the rehearsal simulation system corresponding to the video frame according to the proportional relation and the pixel distance R1;
the actual position of the actor in the preview simulation system is obtained by R1' and angle β.
The idea of an embodiment of the present invention is to convert the actor pixel positions obtained by video recognition into positions in a preview simulation system for comparison with preview simulation data.
According to a specific implementation manner of the embodiment of the invention, the error analysis module outputs the actual motion track of the actor obtained from the collected video data and the standard motion track of the actor obtained according to the preview simulation data to the field command module for presentation.
The method is a method for visually comparing the actor motion track in actual rehearsal with the actor motion track in preview simulation by simultaneously displaying and outputting the two motion tracks, wherein the two motion tracks can be displayed on the same display interface in an overlapping manner, a comparison result can be rapidly provided for field commanders, and the field commanders can visually find whether the actor motion track is consistent with the actor motion track in preview simulation and the deviation is large or small.
According to a specific implementation manner of the embodiment of the present invention, the error analysis module compares the actual position of the actor obtained from the collected video data with the position where the actor should be located in the preview simulation data, and outputs the position deviation to the live commanding module for presentation.
The distance between the actual position of the actor and the rehearsal simulation position obtained by R1' and the included angle β can be selected as a quantitative analysis index of the rehearsal effect in practical application, a threshold value can be set for the index, and the actor is required to rehearse or the expected effect of the rehearsal simulation system is modified after the position error exceeds the threshold value.
According to a specific implementation manner of the embodiment of the invention, the on-site commanding module comprises a plurality of display devices for presenting data and input devices for receiving feedback of commanders; each display device displays data of different areas of a site according to user settings and updates the data in real time; each input device receives feedback and settings from a different commander.
As shown in fig. 3, for a large crowd performance, a plurality of people often command the scene at the same time, a chief deputy is a general command, and a plurality of scene commanders responsible for local areas are arranged in different areas of the scene. Therefore, each field commander can be provided with a display device, the display device can be a handheld display device and is convenient to move, and each display device displays data of different areas of a field according to user settings and updates the data in real time. The command system is very beneficial for regional command personnel to know and master the local and global conditions of the field performance. In the embodiment of the present invention, the handheld display device of each commander also has a function of accepting user input, such as a touch screen or a tablet computer with a touch function. Each device receives feedback and settings from different commanders.
According to a specific implementation manner of the embodiment of the present invention, the live commanding module further includes a remote interaction unit, which is used for remotely transmitting the live performance data and receiving the remote feedback.
In the process of sparring of crowd performance, the situation that key instructors are not on site often occurs. As an embodiment of the invention, the crowd performance scene commanding system also comprises a remote interactive unit, which can enable the director which can not come to the scene to see the scene scouring situation from the remote, and can submit feedback opinions through the remote interactive unit, and can even directly modify various settings of the performance scene at the remote.
