[0014] The present invention has the following beneficial effects: 1. The intelligent lighting adjustment method for the live broadcast stage obtains the number of live broadcast room seat spotlights, obtains the number of divisions, divides the area length by the number of divisions, obtains multiple division lengths, and on the seat area, a rectangle formed by the division length as the length and the area width as the width is recorded as the lighting area, that is, the seat area is divided in the longitudinal direction, so that each seat spotlight corresponds to a lighting area, that is, each seat spotlight can uniformly plan the path, and then uniformly manage to improve efficiency; each seat spotlight corresponds to a lighting area, which reduces the complexity of management and improves efficiency.

[0015] 2. The intelligent lighting adjustment method for the live stage obtains the diameter of the light spot and divides the width of the lighting area with the diameter of the light spot. When the width / diameter of the lighting area is an integer, the width of the lighting area is evenly divided into line segments of the number of rows, and the length of each line segment is the length of the diameter; when the width / diameter of the lighting area is not an integer, the width of the lighting area is evenly divided into line segments of the number of rows, and the length of each line segment is the width / number of rows of the lighting area; similarly, when the length / diameter of the lighting area is an integer, the length of the lighting area is evenly divided into line segments of the number of columns, and the length of each line segment is the length of the diameter; when the length / diameter of the lighting area is not an integer, the length of the lighting area is evenly divided into line segments of the number of columns, and the length of each line segment is the length / number of columns of the lighting area. The lighting area is divided into multiple rows and columns, which is convenient for subsequent lighting path planning. Multiple execution units are convenient for subsequent prediction of whether the actors are illuminated, reducing the complexity of calculation and improving efficiency.

[0016] 3. The intelligent lighting adjustment method for a live stage is as follows: a plane perpendicular to the horizontal plane and parallel to the length of the lighting area is made through the seat spotlight to obtain a limited plane, the distance of the determination line from the limited plane is obtained to obtain a first distance, and the distance of the seat spotlight from the horizontal plane is obtained to obtain a second distance; the farthest distance of the actor from the determination line is obtained to obtain the execution distance, the farthest position of the actor from the determination line is recorded as the marked position, and the height of the light at the marked position is calculated by using the proportional relationship of similar triangles, and compared with the determination threshold, wherein the determination threshold is the height of the actor, when the height of the light at the marked position is less than the determination threshold, the seat spotlight will definitely illuminate the actor in the process of irradiating the determination line; in the process of irradiating the stage from far to near, the light is closest to the stage when irradiating the determination line, and when it is judged that the actor will be irradiated in the determination line, it is judged that the seat spotlight is a constrained spotlight, and the determination line is used to judge whether the seat spotlight is a constrained spotlight, thereby reducing the complexity of judgment and improving the efficiency of judgment.

[0017] 4. The intelligent lighting adjustment method for a live stage records the execution unit farthest from the stage in each column of the lighting area as the first execution unit, and the execution unit closest to the stage as the second execution unit, and sorts each column of the lighting area. For columns with odd numbers, each execution unit is traversed in sequence from the second execution unit to the first execution unit starting from the second execution unit. For columns with even numbers, each execution unit is traversed in sequence from the first execution unit to the second execution unit starting from the first execution unit. The traversal order of odd columns and even columns is different because, when the total number of columns is an odd number, the columns with odd numbers have one more column than the columns with even numbers. The columns with odd numbers are traversed from close to the stage to far away from the stage. In this process, the height of the light from the stage gradually increases. If the light hits the actor, it can be avoided directly without the need for subsequent conversion strategies. This reduces the unlit areas caused by the avoidance strategy, enhances the audience's experience, and improves the efficiency of lighting.

[0018] 5. The intelligent lighting adjustment method for a live stage, when the spotlight is constrained to traverse in the direction from the first execution unit to the second execution unit, executes the judgment strategy for each execution unit in turn, records one of the execution units as a limiting unit, obtains the number of execution units passed from the first execution unit to the limiting unit, obtains the number of traversals, calculates the number of traversals*unit duration, obtains the traversal duration, obtains the initial position and the final position of the actor, calculates the distance between the initial position and the final position, obtains the actor distance, calculates the actor distance / traversal duration, obtains the actor speed, obtains the direction from the initial position to the final position, obtains the actor direction, calculates the actor speed*unit duration, and obtains the predicted distance; records the next execution unit of the limiting unit as a predicted unit, predicts the position of the actor after passing the unit duration when the spotlight is constrained not to illuminate the predicted unit, obtains the predicted position, predicts in the prediction unit whether the light will illuminate the actor, predicts each execution unit in the column one by one, and determines whether it will illuminate the actor, and manages and predicts in a refined manner to increase the area illuminated to the audience as much as possible, improves the interaction intensity of the audience, and enhances the audience's experience.

[0019] 6. The intelligent lighting adjustment method for the live broadcast stage obtains the distance between the prediction unit and the prediction position to obtain the first judgment distance, obtains the distance between the prediction unit and the limited plane to obtain the second judgment distance, and uses the proportional relationship of similar triangles to calculate the height of the light at the predicted position when the actor is at the predicted position. When the height of the light at the predicted position is less than or equal to the judgment threshold, it means that the actor will be illuminated by the light at the predicted position. At this time, the constraint spotlight will illuminate the actor when illuminating the prediction unit, and it is necessary to avoid it to prevent the light from illuminating the actor, making the actor become a black shadow on the stage, reducing the audience's experience.

[0020] 7. The intelligent lighting adjustment method for the live stage, when executing the judgment strategy in the prediction unit, it is judged that the actor will be illuminated by the prediction unit, and the classification avoidance strategy is executed, the odd columns adjacent to the lower column are obtained and converted in forward order to obtain the conversion upper column, and the execution unit adjacent to the limiting unit is obtained in the conversion upper column to obtain the conversion unit. After the constraint spotlight illuminates the limiting unit: the constraint spotlight continues to illuminate the audience seats in the conversion upper column according to the previous traversal order starting from the conversion unit, that is, the constraint spotlight is converted to the next column. Since the next column must be illuminated in sequence from near to far from the stage, that is, the height of the light from the stage gradually increases, it can avoid illuminating the actors on the stage, thereby increasing the audience's experience. Since the seat spotlight will illuminate the audience seats multiple times according to the lighting path, and the position of the actor changes all the time, the unilluminated area is different each time, which avoids an area from being unilluminated multiple times, thereby increasing the audience's sense of interaction.

When the width / diameter of the illumination area is an integer, the width of the illumination area is evenly divided into line segments numbered by rows, and the length of each line segment is the length of the diameter; when the width / diameter of the illumination area is not an integer, the width of the illumination area is evenly divided into line segments numbered by rows, and the length of each line segment is the width / number of rows of the illumination area; similarly, when the length / diameter of the illumination area is an integer, the length of the illumination area is evenly divided into line segments numbered by columns, and the length of each line segment is the length of the diameter; when the length / diameter of the illumination area is not an integer, the length of the illumination area is evenly divided into line segments numbered by columns, and the length of each line segment is the length / number of columns of the illumination area. The illumination area is divided into multiple rows and columns, which is convenient for subsequent planning of the illumination path. Multiple execution units are convenient for subsequent prediction of whether the actor is illuminated, which reduces the complexity of calculation and improves efficiency.

[0028] The execution screening constraint strategy includes: Draw a plane perpendicular to the horizontal plane and parallel to the length of the lighting area through the seat spotlight, which is recorded as the limiting plane; Get the row closest to the live broadcast stage among the n rows and record it as the judgment row; Obtain the distance between the determination line and the defined plane, recorded as the first distance x; Get the distance between the seat spotlight and the horizontal plane, recorded as the second distance y; Get the farthest distance between the actor on the stage and the judgment line during the performance, recorded as the execution distance z; Set the threshold for determining whether the seat spotlight will illuminate the actor; Calculate y*z / x; When y*z / x is less than or equal to the determination threshold, the seat spotlight is a constraint spotlight.

[0029] In this embodiment, Figure 2 As shown, the first distance is the distance between the determination line and the defined plane; The second distance is the distance between the seat spotlight and the horizontal plane; the execution distance is the farthest distance from the judgment line when the actor is performing.

[0030] Through the seat spotlight, a plane perpendicular to the horizontal plane and parallel to the length of the lighting area is drawn to obtain the limited plane, the distance of the determination line from the limited plane is obtained to obtain the first distance, and the distance of the seat spotlight from the horizontal plane is obtained to obtain the second distance; the farthest distance between the actor and the determination line is obtained to obtain the execution distance, and the farthest position of the actor from the determination line is recorded as the marked position, and the height of the light at the marked position is calculated by using the proportional relationship of similar triangles, and compared with the determination threshold, wherein the determination threshold is the height of the actor, when the height of the light at the marked position is less than the determination threshold, the seat spotlight will definitely illuminate the actor in the process of irradiating the determination line; in the process of the seat spotlight irradiating from far to near the stage, when irradiating the determination line, the light is closest to the stage, and when it is judged that the actor will be irradiated in the determination line, it is determined that the seat spotlight is a constrained spotlight, and the determination line is used to determine whether the seat spotlight is a constrained spotlight, thereby reducing the complexity of the judgment and improving the efficiency of the judgment.

[0031] The execution of the lighting path planning strategy includes: For any column in the lighting area: The execution unit farthest from the stage is recorded as the first execution unit; The execution unit closest to the stage is recorded as the second execution unit; Sort each column of the lighting area; The order of the serial numbers from small to large is the positive order; Traverse each column in forward order; When the column number is odd: Taking the second execution unit as the starting point, traverse each execution unit in sequence from the second execution unit to the first execution unit; When the column number is even: Taking the first execution unit as the starting point, each execution unit is traversed in sequence from the first execution unit to the second execution unit.

[0032] In this embodiment, Figure 1 As shown, the five columns are named the first column, the second column, the third column, the fourth column and the fifth column respectively; For the first, third, and fifth columns; The direction of the seat spotlight traversal is to take the second execution unit as the starting point and traverse each execution unit in sequence from the second execution unit to the first execution unit; For the second and fourth columns; The direction of the seat spotlight traversal is to take the first execution unit as the starting point and traverse each execution unit in sequence from the first execution unit to the second execution unit.

[0033] The execution unit farthest from the stage in each column of the lighting area is recorded as the first execution unit, and the execution unit closest to the stage is recorded as the second execution unit. Each column of the lighting area is sorted. For columns with odd numbers, each execution unit is traversed in sequence from the second execution unit to the first execution unit starting from the second execution unit. For columns with even numbers, each execution unit is traversed in sequence from the first execution unit to the second execution unit starting from the first execution unit. The traversal order of odd-numbered columns and even-numbered columns is different because, when the total number of columns is odd, the columns with odd numbers have one more column than the columns with even numbers. The columns with odd numbers are traversed from close to the stage to far away from the stage. In this process, the height of the light from the stage gradually increases. If the light hits the actor, it can be avoided directly without the need for subsequent conversion strategies. This reduces the unlit areas caused by the avoidance strategy, enhances the audience's experience, and improves the efficiency of lighting.

[0034] In the process of constraining the spotlight to illuminate the audience seats, predicting whether the actor is illuminated includes: Get the duration of the constraint spotlight moving from one execution unit to an adjacent execution unit, recorded as unit duration; When constraining the spotlight to traverse from the first execution unit to the second execution unit: When the constraint spotlight illuminates the first execution unit, the actor's position is obtained and recorded as the initial position; Starting from the first execution unit, traverse each execution unit in turn: Get an execution unit, recorded as a limiting unit; Obtain the number of execution units passed from the first execution unit to the limiting unit, recorded as the traversal number; Calculate the number of traversals * unit duration = traversal duration; When the constraint spotlight is in the limited unit, obtain the actor's position and record it as the end position; Get the distance between the initial position and the final position, recorded as the actor distance; Calculate actor distance / traversal time = actor speed; Get the direction from the initial position to the final position, recorded as the actor direction; Calculate actor speed * unit time = predicted distance; Get the position of the actor according to the predicted distance of the actor's movement direction, and record it as the predicted position; Get the next execution unit of the limited position, recorded as the prediction unit; Execute the decision strategy to determine whether the constraint spotlight will illuminate the actor in the prediction unit.

[0035] When the constraint spotlight traverses from the first execution unit to the second execution unit, the judgment strategy is executed on each execution unit in turn, one of the execution units is recorded as the limiting unit, the number of execution units passed from the first execution unit to the limiting unit is obtained, the traversal number is obtained, the traversal number*unit duration is calculated to obtain the traversal duration, the initial position and the end position of the actor are obtained, the distance between the initial position and the end position is calculated to obtain the actor distance, the actor distance / traversal duration is calculated to obtain the actor speed, the direction from the initial position to the end position is obtained to obtain the actor direction, the actor speed*unit duration is calculated to obtain the predicted distance; the next execution unit of the limiting unit is recorded as the predicted unit, when the constraint spotlight does not shine on the predicted unit, the position of the actor after passing the unit duration is predicted to obtain the predicted position, the prediction unit predicts whether the light will shine on the actor, and each execution unit in the column is predicted one by one to determine whether it will shine on the actor, and refined management and prediction are carried out to increase the area shining on the audience as much as possible, improve the interaction intensity of the audience, and enhance the audience's experience.

[0036] The execution determination strategy includes: Obtain the distance between the prediction unit and the prediction position, recorded as the first determination distance h1; Obtaining the distance between the prediction unit and the defined plane, recorded as the second determination distance h2; Calculate h1*y / h2; When h1*y / h2 is less than or equal to the decision threshold, the spotlight is constrained to illuminate the actor in the prediction unit.

[0037] In this embodiment, when the constraint spotlight traverses the second column, the execution units of the second column are named as the first marking unit, the second marking unit, the third marking unit, the fourth marking unit and the fifth marking unit respectively; Wherein, when the limiting unit is the third marking unit, the predicting unit is the fourth marking unit; When the third marker unit predicts that the constrained spotlight is illuminating the fourth marker unit, the light will illuminate the actors on the stage; The distance between the prediction unit and the prediction position is obtained to obtain the first judgment distance. The distance between the prediction unit and the limited plane is obtained to obtain the second judgment distance. The proportional relationship of similar triangles is used to calculate the height of the light at the prediction position when the actor is at the prediction position. When the height of the light at the prediction position is less than or equal to the judgment threshold, it means that the actor will be illuminated by the light at the prediction position. At this time, the constraint spotlight will illuminate the actor when illuminating the prediction unit, and it is necessary to avoid it to prevent the light from illuminating the actor, making the actor become a black shadow on the stage, reducing the audience's experience.

[0038] The execution of the classification avoidance strategy includes: When the constraint spotlight is predicted to illuminate the actor during the process of traversing the columns, the column that will illuminate the actor is recorded as the transition bottom column; Obtain and convert the odd-numbered columns adjacent to the lower row columns in the forward order, and record them as the converted upper row columns; Get the limited unit in the conversion line column; Obtain the execution unit adjacent to the limiting unit in the conversion row and column, and record it as the conversion unit; When the constraint spotlight illuminates the limited unit: The spotlight will be constrained to continue illuminating the audience seats starting from the transformation unit in the transformation row according to the previous traversal order.

[0039] In this embodiment, the second column is the conversion lower column, the third column is the conversion upper column, the limiting unit is the third marking unit, and the conversion unit is the execution unit adjacent to the limiting unit in the conversion upper column. Then, when the constraint spotlight illuminates the limiting unit: The spotlight will be constrained to continue illuminating the audience seats starting from the transformation unit in the transformation row according to the previous traversal order.

[0040] When the judgment strategy is executed in the prediction unit, it is determined that the actor will be illuminated in the prediction unit, and the classification avoidance strategy is executed. The odd columns adjacent to the lower column are obtained and converted in forward order to obtain the converted upper column. The execution unit adjacent to the limiting unit is obtained in the converted upper column to obtain the converted unit. After the constraint spotlight illuminates the limited unit: the constraint spotlight continues to illuminate the audience seats from the conversion unit in the converted upper column according to the previous traversal order, that is, the constraint spotlight is converted to the next column. Since the next column must be illuminated from near to far from the stage, that is, the height of the light from the stage gradually increases, it can avoid irradiating the actors on the stage, thereby increasing the audience's experience. Since the seat spotlight will illuminate the audience seats multiple times according to the lighting path, and the position of the actor changes all the time, the unilluminated area is different each time, avoiding an area from being unilluminated multiple times, thereby increasing the audience's sense of interaction.
