[0048] like Figure 1 As shown, the first embodiment of the present invention is: a method for synchronizing a motion device with a video screen, comprising:

[0049] S1. Obtaining the original data mark action block information pair of the dynamic device; the dynamic device is a six-degree-of-freedom platform mechanism, and the platform has a mechanical structure of a carriage seat;

[0050] Furthermore, step S1 specifically includes:

[0051] S11, binding the 3D model of the dynamic device in the 3D software, so that the 3D model of the dynamic device can be dragged according to the actual mechanical movement mode;

[0052] S12, dividing the film into sequence frame images, and importing them into 3D software to produce key frame curves of dynamic device actions; the frame rate set when producing the key frame curves of dynamic device actions is consistent with the frame rate of the film; the frame rate of the film is usually 24fps or 25fps; the 3D software can be Maya, Blender and other animation production software;

[0053] S13, calculating and outputting the motion axis data of the dynamic device and the corresponding film frame data; Figure 3 shown.

[0054] The motion axis data of the dynamic device is saved as a computer data file format txt\csv\xls; ​​when outputting data, if the data output frame rate is inconsistent with the film frame rate, the output film frame number is linearly interpolated, and floating point numbers are allowed in the film frame number;

[0055] S14, select the mark action block: Figure 4 The boxes show two marked action blocks. For the motion axis data corresponding to the film, a time window size q of a certain length is set. Several substrings are selected in the motion axis sequence as different marker action blocks. The starting time of each marker action block corresponds to the film frame number. The motion axis data of each film can be divided into a certain number of marker action blocks, thereby obtaining the "film theoretical trigger time-marker action block theoretical trigger time-film frame" information pair; wherein q represents the number of single motion axis data in the marker action block.

[0056] Furthermore, step S11 specifically includes:

[0057] S111, the six-degree-of-freedom upper platform of the dynamic equipment and the car seat model are taken as a model group SA, and the upper end points of the telescopic mechanisms of each motion axis are up k As a child object of SA, it can follow SA's displacement and rotation; k represents the motion axis number;

[0058] S112, up the upper end point of the telescopic mechanism of the motion axis k and the lower endpoint down k Perform target constraints or bone binding to ensure that the upper and lower endpoints have the correct pointing relationship when the upper platform is displaced and rotated.

[0059] Further, in step S12, the key frame curve of the dynamic device is composed of time t l ,l=1,…,n and its corresponding frame value x l ,l=1,…,n to determine, where x is the carriage displacement parameter or Euler angle parameter, namely the carriage x-axis displacement, y-axis displacement, z-axis displacement, x-axis rotation, y-axis rotation, and z-axis rotation.

[0060] Furthermore, in step S13, the motion axis of the dynamic device is the motion axis of the drive unit of the oil cylinder and electric cylinder device; the motion axis data is the length sequence of the oil cylinder and electric cylinder based on the time sequence, and the film frame data is the film frame number sequence based on the time sequence.

[0061] The motion axis data of the dynamic device can be one motion axis or multiple motion axis data, and p is used to represent the number of motion axes;

[0062] There is a certain time interval between the two units before and after the motion axis data mark action block of the film. No two blocks of the mark action block in the same film can be the same. The motion axis data corresponding to each mark action block is saved as an independent data file. The selection of the mark action block avoids selecting the motion axis motion static segment; the number of mark action blocks divided for each film is represented by j, j = 1, ..., N, the number of films is represented by i, i = 1, ..., M, and the mark action block is represented by B ij ; The movie frame corresponding to the starting point of the action block is TF ij ;

[0063] The value of the time window size q of the motion axis data of the marker action block is related to the current length of the film and the complexity of the key frame curve of the dynamic device action. Usually, the time window size of the motion axis data of the marker block is set to ensure that the motion axis data is variable and should cover the dynamic process of at least one car action. The number of marker action blocks that need to be divided for each film is related to the number of synchronization point actions that need to be identified. Usually, when the dynamic device car action and the film picture are accurately matched, it can bring a real immersive experience to the passengers, or the film picture that needs to be highlighted during design is selected as the synchronization point. The starting position of each marker action block is specified by the design engineer. After specifying the expected number of marker action blocks, the program is still required to determine whether there are the same marker action blocks divided by the current film. If the same part appears, one of them needs to be modified or discarded. After selecting the marker action blocks, each marker action block is saved as a separate data file.

[0064] S2, obtaining movie picture playback data information, wherein the movie picture playback data information includes world time and movie frame number; the movie picture playback data information is complete and continuous data without missing information;

[0067] The actual operation data of the dynamic equipment is complete and continuous data without missing information. According to the screen position and the number of videos in the project, the actual operation data of the dynamic equipment is divided into i parts, each of which is represented by A i Indicates the actual execution status of the corresponding dynamic device in each screen area;

[0068] The actual operation data of the dynamic equipment is collected in real time by the lower computer program system; the motion axis data of the dynamic equipment is selected from the collected data, and the data is processed to determine whether it is continuous and complete.

[0069] S4, finding the position of each marker action block in the actual operation data of the dynamic device;

[0070] Further, step S4 specifically includes:

[0075] S45, the starting position corresponding to the minimum value in the sumAver sequence is the marker action block B ij The position in the actual operation data of the dynamic equipment.

[0076] In the case of multiple movie data, the actual operation data of the dynamic device is cut according to the movie scene and divided into multiple data files. The marked action block of each movie is only searched in the corresponding segmented actual operation data of the dynamic device to avoid cross-movie search, improve accuracy and reduce search time. The frequency of collecting movie screen playback information and actual operation data of the dynamic device is consistent with the output frequency of the theoretical data of the motion axis of the dynamic device. Here it is 10HZ. When the acquisition frequency is higher than the output frequency, the output data must be sparsely jumped so that the frequency of the sparse output data is consistent with the frequency of the collected data.
