A dynamic seat control method with a path derived from a camera

Abstract

The present invention discloses a dynamic seat control method based on a camera exported path, comprising the following steps: recording rotation angle change parameters of a footage during a playing process of a film with a selected time length; obtaining a telescoping range of a telescoping cylinder of a dynamic seat and a maximal length of the telescoping cylinder; calculating variable quantity of telescoping length of the telescoping cylinder at each moment during the selected time length by using the Pythagorean theorem according to the rotation angle change parameters, the maximal length and the telescoping range of the telescoping cylinder, setting a time line of movement of the dynamic seat, and calculating the variable quantity of the telescoping length at each moment on the time line, so as to achieve control of the dynamic seat. According to the dynamic seat control method of the present invention, movement of the footage is directly obtained, and the movement is changed into telescoping movement and rotation movement of the telescoping cylinder of the dynamic seat through simple computation of the Pythagorean theorem, in this way, accuracy of movement capture is greatly improved, and the situation that the movement of the dynamic seat needs to be set manually in the prior art can be avoided during the whole process, thereby greatly improving an adjusting efficiency of the dynamic seat, and saving labor cost.

Description

technical field [0001] The invention relates to a control method of a dynamic seat, in particular to a control method of a dynamic seat that derives a path through a camera. Mainly related to patent classification number, G05 control; control of adjusting G05D non-electric variable or adjusting system G05D3 / 00 control of position or direction. Background technique [0002] The control of the existing dynamic seat, especially the cooperation between the seat and the film, usually uses a Flash editor for matching control. During operation, it is necessary to manually adjust the motion track of the seat. During the adjustment process, the designer needs to manually stretch the virtual seat. The movement trajectory of the seat is tedious, the whole process is cumbersome, the production cycle is long, and the accuracy is very low, which requires subsequent complicated correction process. Contents of the invention [0003] Aiming at the above problems, the present invention pro...
