Control system and control method for visual adjustment of shutter sheets for stage lighting

Abstract

The invention discloses a control system and a control method for visual adjustment of shutter sheets for stage lighting. The control system comprises a display screen, a light control module, a storage module and a shutter sheet driving mechanism, wherein the light control module is used for controlling luminaire shutter sheets and diaphragms, and the storage module is used for storing shutter sheet control threshold parameters and diaphragm parameters. The display screen, the storage module and the shutter sheet driving mechanism are all connected with the light control module. The shutter sheet driving mechanism is connected with a shutter sheet. By establishing a visual platform and using the single-control-point control way, the control system has the advantages of simplicity, convenience, quickness, visuality and the like in control. A precise algorithm is designed for conversion of a control point to a shutter sheet position, smooth and stable operation is guaranteed, and the shutter sheet can be controlled to precisely move to achieve the expected diaphragm sectional cutting effect so as to obtain an expected beam shape.

Description

technical field [0001] The invention relates to the field of stage lamp control, in particular to a visual adjustment control system of a stage lamp light cutting slice and a method for visually adjusting a stage lamp by using the system. Background technique [0002] In the field of stage lighting, projection lamps are usually used to project light. However, the light source projection opening of existing lamps is fixed. To change the beam shape of light projected by lamps, it is generally achieved by rotating light slice technology. Specifically: there are four sets of light cutting sheets (upper light cutting sheet, left light cutting sheet, lower light cutting sheet, right light cutting sheet) at the light projection port of the lamp (that is, around the aperture), and the four groups of light cutting sheets It can go straight or rotate within a certain range to cut the shape of the beam section; the lighting designer configures and arranges the four groups of light cutt...

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing lighting console system, there are mainly the following ways to control the light cutting sheet: (1) Directly input the parameter value, that is, the user directly inputs the parameter value by rotating the control button, and the central processing in the lighting console system According to the parameter value, the device sends relevant control commands to the motor that controls the light cutting sheet, and then drives the light cutting sheet to move to the corresponding position through the motor, and cuts the shape of the aperture section to achieve the purpose of changing the beam shape of the light projected by the lamp. Although this control method can change the beam shape, it is not intuitive enough. Users need to input parameter values ​​based on experience. For operators who are not very experienced, if they want to adjust to the expected beam shape, they can only use Constantly trying to input different parameter values ​​until the desired effect is achieved, the whole process is time-consuming, cumbersome, and very inconvenient to operate; (2) Through visual interactive control, multiple control is determined for each group of slices on the visual platform Points, and then convert the coordinate information of multiple control points into control signals to drag a group of slices. Although this method is more intuitive than the former, but because multiple control points need to be determined, there are many control points, Defects such as insufficient feedback of the effective range of control points

It can be seen that in the prior art, the control method of the light slice generally has defects such as not intuitive enough, inconvenient to operate, etc.
