Method for generating dynamic data of dynamic seat based on video processing

Abstract

The invention discloses a method for generating dynamic data of a dynamic seat based on video processing. The method comprises the following steps of identifying an image of a film video, and selecting a plurality of feature points of any feature objects on the image as required; tracking the position change of all the feature points through a video processing algorithm by utilizing a computer; calculating and obtaining a movement parameter and a movement trail of a virtual camera through video processing algorithm according to the position change of the feature points; calculating and obtaining the practical movement trails and movement parameters of the feature objects through the video processing algorithm according to the movement parameter and the move trail of the virtual camera; generating the dynamic data of the dynamic seat according to the practical movement trails and the movement parameters of the feature objects. By means of the method for generating dynamic data of the dynamic seat based on video processing, automatic generation of the dynamic data is almost achieved, generation efficiency of the dynamic data is greatly improved, accuracy of the dynamic data obtained through the method is obviously improved, and the method can eliminate the hysteretic property of the dynamic data.

Description

technical field [0001] The invention relates to the technical field of dynamic seats, in particular to a method for generating dynamic data of a dynamic seat based on video processing. Background technique [0002] As we all know, with the development of 3D movies, dynamic seats are more and more widely used in 3D theaters. When the film is shown, the dynamic seat can make various actions with the change of the plot, so as to bring the audience an immersive feeling. This advantage of the dynamic seat has won the favor of the majority of movie lovers. [0003] Before each film is shown in the 3D theater, technicians need to obtain the motion data of the film's dynamic seats and send it to the theater. When the movie starts to be shown, the theater will send the dynamic seat movement data to each dynamic seat, and the dynamic seat will make corresponding actions according to its movement data. For a film that is about to be released, how to obtain the corresponding dynamic ...

AI Technical Summary

Problems solved by technology

[0006] (1) It takes a lot of manpower, the efficiency is low, and the cost is high;

[0007] (2) Different technicians face the same scene of the film, and there are great individual differences in their inner experience and feelings, so the accuracy of the above method is low;

[0008] (3) The technician can react only after seeing the scene of the movie being shown, and then shake the joystick. It takes a certain amount of reaction time from seeing the scene of the movie to shaking the joystick, so there is a lag in the generation of dynamic data by the above method , so it is easy to affect the feeling effect that the dynamic seat brings to the audience in practical application;

[0009] (4) For some sports with high similarity or even the same motion, the generation process of the motion data cannot be effectively copied or repeated. Therefore, for the same motion, the motion data generated by the above method lacks consistency, which leads to the lack of consistency of motion data in practical applications. The effect that the chair brings to the audience is also lack of consistency
