In order to achieve the performance effect, in modern stage design, a large number of stage lamps are often required to be installed, but the brightness control of the stage lamps is very complex, in order to ensure that each audience can have a good sight line and the stage effect is more stable, proper brightness must be ensured, the stage lamps are various in variety, the stage lamps are difficult to be comprehensively controlled after being started, and a large amount of debugging is often required before performance, so that time is consumed, and manpower and material resources are wasted.
Example one
As shown in fig. 1, which is only one embodiment of the present invention, the present invention provides a stage lighting control method, including the steps of:
s1: acquiring diffusion values of each angle of the stage lamp;
the diffusion value is that the stage lamp is along with distance and angle, and light irradiation intensity distributes, like this only need in advance with the stage of each model etc. test can, during the stage performance, combine the position of the relative stage of stage lamp according to the diffusion value of this test, can know the illumination effect of this stage lamp on the stage, analog display on the computer can carry out accurate control.
Of course, before the step S1 is executed, the stage light spread value is calibrated. Namely, a light simulation test is performed.
Moreover, the stage lighting diffusion value is calibrated, and the specific steps comprise:
s11: turning on a stage light;
s12: arranging a receiving plate provided with a plurality of groups of photosensitive members in front of the stage lamp;
s13: acquiring the distance between a current receiving board and a stage lamp and the reading of each photosensitive part;
s14: the receiving board position is moved a plurality of times, and steps S12 to S14 are repeatedly performed to generate spread values of the respective angles of the stage lamp.
It should be noted that, in step S14, the position of the movable receiving board includes a horizontal displacement and a vertical displacement, and the horizontal displacement can be used to test the radiation diffusion effect of the stage lamp on various angles at a certain height; and the vertical displacement can test the radiation diffusion effect of the stage lamps at the same place and different heights.
And inputting the position of the receiving plate and the reading data of each photosensitive part into a computer, and obtaining the diffusion value of each angle of the stage lamp by the computer according to fuzzy calculation.
S2: turning on the stage lamp, calculating the distance between the stage lamp and the stage, and acquiring the angle value of the stage lamp relative to the stage;
the distance between the stage lamp and the stage can be directly calculated, and the angle value of the stage lamp relative to the stage needs to obtain the boundary of the stage and calculate the angle range of the stage lamp relative to the stage.
S3: selecting any point of the stage, reading the actual light brightness value at the point, obtaining a correction value, and generating a stage illumination brightness distribution rule;
and (4) optionally selecting a point on the stage, and calculating the theoretical light brightness at the point by the computer according to the position of the point and the position of the stage lamp.
However, the actual light intensity at this point must be slightly wrong due to reflections of the in-situ air particles and other objects, and should actually be lower than the theoretical value.
And reading the actual light brightness value at the point, and comparing the actual light brightness value with the theoretical light brightness calculated by the computer to obtain a corrected value.
The correction value is substituted into a calculation algorithm, so that the current stage background influence parameter can be obtained, and the actual light diffusion value of the stage lamp can be obtained.
S4: when any stage lamp is turned on or turned off, obtaining a target stage illumination brightness distribution map according to the position of the stage lamp;
in the invention, the stage lamp is not directly switched on or off, but is controlled by a computer, if a command is executed, only the position number of the target stage lamp is required to be input into the computer, and the computer carries out stage lamp simulation operation according to the parameters of the stage lamp to obtain a distribution graph expected to generate stage lighting illumination.
S5: judging whether any point in the target stage illumination brightness distribution diagram exceeds a preset illumination intensity range, if so, not allowing the stage lamp to be operated; otherwise, the operation is allowed and the process continues to step S4.
And calculating the generated predicted lighting effect distribution, comparing the predicted effect distribution map, and comparing whether a target effect can be obtained or not, wherein if the difference is large, the stage effect can be influenced, unnecessary flaws are caused, and when the operating signal of the stage lamp passes through the computer, the computer denies and does not perform predicted operation on the stage lighting.
Effectively avoid suddenly debugging light to cause dazzling or dim effect like this, the stage integrity is higher, and the stage effect is better.
And all lights are compared with feasibility through simulation operation, error operation is effectively avoided, the control process is intelligent and accurate, the stage effect is more guaranteed, even if diffusion value calibration is carried out on each stage lamp in advance, only the step S2 and the step S3 need to be executed in the stage building process to obtain the correction value of the current stage, and debugging time can be greatly shortened.
The stage lighting control method is convenient to control, good in stage effect, high in intelligence degree, capable of effectively simulating light distribution, short in debugging time and suitable for quickly mounting the stage.
Example two
Still referring to fig. 1, still another embodiment of the present invention is a stage lighting control method, in order to make the control more stable and the simulation calculation accuracy higher, the present invention further has the following designs:
first, when step S2 is executed, only one stage lamp is turned on. Interference is avoided, and the obtained correction value is more accurate.
And when the step S2 is executed, the stage is divided into at least one stage unit, the distance between the stage lamp and each stage unit is calculated, and the angle value of the stage lamp relative to each stage unit is obtained. The smaller the stage unit division, the more accurate the final generated stage illumination intensity distribution map.
Then, when step S3 is executed, after any one point of the stage is selected, the stage unit to which the point belongs is obtained first, and then the actual lighting brightness value at the point is read.
And when step S3 is executed, it is determined whether the correction value is between 0 and 1, and if so, step S4 is continuously executed; otherwise, go back to step S2. Because light loss is caused in the actual scene of the stage, the actual illumination intensity of stage lighting is definitely lower than the theoretical illumination intensity, the correction value is between 0 and 1, if the correction value is greater than 1, unknown errors exist, or other lighting interference tests need to be carried out, and the error check can be carried out to accurately control the stage lighting.
In step S4, the current stage lighting intensity distribution map is added to the expected variation value to generate a target stage lighting intensity distribution map.
Finally, a predetermined illumination intensity range is generated before step S5 is executed.
In addition, when step S5 is executed, if the stage light is not allowed to be operated, warning information is sent out to prompt the operator that there is an error, so that the operator can perform better stage light planning.
The stage lighting control method is convenient to control, good in stage effect, high in intelligence degree, capable of effectively simulating light distribution, short in debugging time and suitable for quickly mounting the stage.
