Detailed Description
The following are specific examples of the present invention and further describe the technical solutions of the present invention, but the present invention is not limited to these examples.
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the modules and steps set forth in these embodiments and steps do not limit the scope of the invention unless specifically stated otherwise.
Meanwhile, it should be understood that the flows in the drawings are not merely performed individually for convenience of description, but a plurality of steps are performed alternately with each other.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
With the increasing abundance of cultural life, people have higher and higher requirements on stage effects in performance activities, stage lights are important components of performance space, and are artistic creations for carrying out omnibearing visual environment light design on characters and required specific scenes according to the development of plot and reproducing design intentions to audiences in a visual image mode purposefully. 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, and the requirement on conditions for triggering light change is very high, namely, the light needs to be controlled by light change under specific conditions.
Example one
As shown in fig. 1, which is only one embodiment of the present invention, the present invention provides an intelligent light control method, including the following steps:
s1: numbering the light irradiation states in sequence according to the change sequence;
and sequencing the lighting states before and after the change according to the lighting sequence of the stage performance, and numbering in sequence. That is, the light irradiation state of the lamp 1 is the initial light irradiation state of the stage, the light irradiation state of the lamp 2 is the first light irradiation state of the stage after the change, the light irradiation state of the lamp 3 is the second light irradiation state of the stage after the change, and so on. During the stage performance, light becomes No. 2 lamp light irradiation state from No. 1 lamp light irradiation state, then becomes No. 3 lamp light irradiation state, analogizes with the same reasoning, ends until the performance.
Generally, the light irradiation state of No. 1 is an irradiation state in which all lights are turned off before the performance is formally started.
And each time the light changes, the light changes are recorded as closing part of light, then part of light is opened, and the light irradiation change is completed.
S2: inputting a human body control posture corresponding to each change of the lamplight irradiation state;
the condition when the light irradiation state changes every time is recorded in advance, for example, the performance starts, the light irradiation state of No. 1 is on the stage, the moderator stands to the center of the stage, the bowing is headquarter after the lecture is finished, the light needs to be changed from the light irradiation state of No. 1 to the light irradiation state of No. 2, and then the bowing control posture corresponding to the light irradiation state of No. 1 is recorded. Of course, at least one human body control gesture is recorded, and all human body control gestures corresponding to all light irradiation state changes are recorded.
Then, the human body control postures correspond to the light irradiation states in a one-to-one correspondence mode. For example, the bow control posture corresponding to the change in the control light from the light irradiation state of No. 1 to the light irradiation state of No. 2 is described as the human body control posture No. 1.
S3: when stage performance is carried out, the current human body action posture is obtained, and action posture characteristics are extracted;
in the stage performance process, the human body action posture of a person on the stage is acquired in real time, practically, each action of each person is acquired to generate an image, and then the human body action characteristics in each image are sequentially analyzed.
In fact, the extracted motion and posture features include gestures of the performer, body motions of the performer, and a stage property placement position.
S4: judging whether the similarity between the current action posture characteristic and the human body control posture is higher than a preset threshold value, if so, executing step S5, otherwise, not executing operation;
in practice, after the human body control posture is acquired in step S2, the posture is subjected to feature point differentiation. And judging whether the acquired motion characteristics accord with the characteristic points of a certain human body control posture, then comparing the characteristic points, and if the similarity of the characteristic points is higher than a preset threshold value, indicating that the performer on the stage makes the human body control posture, namely sending a light control signal. Otherwise, if the similarity of the feature points is not higher than the predetermined threshold, no operation is performed.
When step S4 is executed, the motion posture characteristics are sequentially subjected to similarity determination for each human body control posture.
S5: and judging whether the human body control posture corresponds to the current light irradiation state, if so, changing the light irradiation state, otherwise, prompting, and repeatedly executing the step S3.
Not all human body control postures are suitable for light regulation control, the current light irradiation state needs to be obtained, the light irradiation state can be controlled to change only when the current light irradiation state is changed into the human body control posture corresponding to the next light irradiation state, actually, whether the number of the human body control posture corresponds to the number of the current light irradiation state or not is judged, for example, when the bow control posture corresponding to the human body control posture No. 1 is made, if the real-time stage lighting state is the lighting state of the lamp No. 1, the stage lighting state is changed to No. 2 lighting state, otherwise, if the stage lighting state is No. 2 or other lighting state, the lighting state change control cannot be performed, and a prompt is given at this time, which should prompt the performer whether to make a wrong motion or not or to give a wrong instruction unintentionally without affecting the performance.
Like this the performer makes the action of according with the terms in the time of according with the conditions on the stage, and this instruction is sensed to the inductor on the stage, sends to light controller and carries out the opening and close of adaptation to light, accomplishes the change control of stage lighting, and light control is more intelligent like this, the greatly reduced of error rate.
The intelligent light control method is convenient to control, intelligent and reasonable, the light change is controlled by specific actions of performers on the stage, the change program can be set in advance, the light change accuracy is higher, the error is smaller, and manual control by workers is not needed.
Example two
Still as shown in fig. 1, it is still one embodiment of the present invention, and in order to make the intelligent light control method of the present invention more convenient to control and more accurate to adjust, the present invention further has the following designs:
first, when step S1 is executed, the light irradiation state before and after each change is generated, and the optimum change control method is established. That is to say, when the light is changed from the light irradiation state of No. 2 to the light irradiation state of No. 3, if the light which does not need to be turned off is provided, the control is not performed, only the light which needs to be turned on is controlled to be turned on, and the light which needs to be turned off is controlled to be turned off.
In fact, the lighting state should be programmed into the lighting controller for each change, and the optimal control should be performed for each change.
Then, before step S3 is executed, a sensing area for obtaining the current body motion posture is set, and in order to increase the accuracy and the reasonableness of the control, the body control posture needs to be made in a specific stage sensing area to perform the light control, although the sensing area for each body motion posture may be different.
Then, before step S4 is executed, a predetermined threshold is set. Generally, the predetermined threshold is determined according to the accuracy of the sensor sensing identification and the complexity of the field, and the predetermined threshold can be manually set in advance.
When step S2 is executed, the special human body control posture in which the control returns to the previous light irradiation state is entered.
Finally, when step S5 is executed, it is determined whether the human body control posture is a special human body control posture, and if so, the control light irradiation state is changed to return to the last light irradiation state, otherwise, it is further determined whether the human body control posture corresponds to the current light irradiation state. Once the misoperation is identified as effective operation, the performer can make a special human body control gesture, return to the previous light irradiation state and continue to perform light control, so that the accidental conditions of the performance can be timely remedied.
The intelligent light control method is convenient to control, intelligent and reasonable, the light change is controlled by specific actions of performers on the stage, the change program can be set in advance, the light change accuracy is higher, the error is smaller, and manual control by workers is not needed.
