The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
With the increasing demand of audiences on cultural arts, the performance forms are diversified, and more performances and ceremonies, such as stage dramas, wedding ceremonies, meeting place opening scenes, closed scenes and the like, are selected to be displayed on the stage. In order to highlight a central character and to highlight a scene atmosphere, stage lighting effects are becoming increasingly important, wherein one special stage lighting effect is to follow a spot, and the spot is matched with a scene requirement by aiming an actor or character to be highlighted with a concentrated light column under the condition that the whole stage is dark, or the actor or character is supplemented with light.
Based on this, the embodiment of the application provides a light following method to solve the problems that the light following lamp needs to be manually operated to move along with an actor, so that the light following is not timely and the light following position is inaccurate.
Fig. 1 is a flowchart of a light following method provided in an embodiment of the present application, for a stage light control device, where the method includes:
s101: and receiving the coordinate information of at least one candidate light following object on the scanning plane of the laser radar, which is sent by at least one laser radar in real time.
It should be noted that, considering the height factor of the persons on the stage, the installation position of the lidar is required to be set at a height position which is 70cm to 90cm away from the stage in addition to ensuring that the scanning plane is parallel to the upper surface of the stage, so that the accuracy of the lidar in detecting the persons can be improved. The coordinate information of the candidate light following object generated by the laser radar is equivalent to a two-dimensional coordinate on a scanning plane of the laser radar, and the two-dimensional coordinate may be an xy coordinate or a polar coordinate representing an angle and a distance, where, taking the xy coordinate as an example, a coordinate system of the scanning plane may use the laser radar as a coordinate origin or a stage center as the coordinate origin. In addition, the laser radar continuously scans the stage at a fixed frequency and periodically sends the detected coordinate information of the candidate light-following object to the stage light control equipment, so that the stage light control equipment needs to utilize the real-time coordinate information of the candidate light-following object to perform the next control in order to accurately grasp the position of the candidate light-following object, which means that the stage light control equipment needs to receive the real-time coordinate information of the candidate light-following object sent by the laser radar in real time to improve the accuracy of light-following. The number of the laser radars can be set according to a specific application scene, for example, when facing a common wedding stage, the number of characters is small, and a situation of multiple rows of characters generally does not occur, one laser radar can be set to detect a candidate light following object; for another example, in the case of a performance, when two characters on the stage face the same lidar and are superposed, the lidar can only recognize one of the characters, so that in order to comprehensively recognize all the characters on the stage, two lidars can be respectively arranged on two opposite sides of the stage, so that all the characters on the stage can be comprehensively covered, and the scanning accuracy is improved.
S102: and confirming at least one target light following object from the candidate light following objects according to the current tracking mode.
It is worth to be noted that the stage light control device may set a plurality of different tracking modes, and a user selects and adjusts the tracking mode according to actual needs on site, the tracking mode is realized by setting a target light-following object, the lidar takes all characters appearing on the stage as candidate light-following objects, and the light-following objects are often a small number of one or several people due to performance or ceremony needs, so that the tracking mode may determine the target light-following object from the candidate light-following objects. For example, four persons including a, b, c and d exist on the stage, and if the tracking mode is set to track the first person alone, the first person is set as a target light-following object; if the tracking mode is set to track A, B and C, three people of A and B are set as target light-following objects. The user can also preset corresponding tracking modes in the stage light control equipment in advance according to the light following requirements of the stage performance, specific tracking characters of each tracking mode are determined, the user can select the corresponding tracking modes according to specific plot opportunities of the performance conveniently, and then when the stage performance is entered, the stage light control equipment can read out the target light following objects selected from the candidate light following objects according to the selection of the user, namely the setting of the current tracking mode, so that the next specific light following operation is carried out.
S103: and distributing a real-time follow spot for each target follow spot according to the number and coordinate information of the target follow spots and pre-stored follow spot information, wherein each follow spot information correspondingly records the space coordinate taking the scanning plane as a reference plane.
It is worth to be noted that a plurality of follow spot lamps are arranged on the stage site, the positions of the follow spot lamps are fixed, and the unique identifier and the spatial coordinates belonging to the follow spot lamp are recorded in the follow spot lamp information corresponding to each follow spot lamp according to the matching requirement. The coordinate information of the target follow spot object identified by the laser radar is a two-dimensional coordinate taking a scanning plane of the laser radar as a reference plane, the follow spot lamp is projected to the scanning plane to obtain the two-dimensional coordinate of the follow spot lamp on the scanning plane, and the follow spot lamp is provided with height information, so that the three-dimensional space coordinate of the follow spot lamp can be obtained by adding the height information of the follow spot lamp. The following effect of the following spot lamp on the target following spot object is realized by means of the rotation of the following spot lamp. In order to obtain the rotation angle, the stage light control device needs to know the unique identifier of each follow spot lamp to match with the target follow spot object in addition to the coordinate information of the target follow spot object, and further calculate the corresponding angle according to the coordinate information of the follow spot lamp, so that the stage light control device needs to store the coordinate information of the follow spot lamp in advance. In addition, the real-time follow spot lamp is used for covering the position of the coordinate information of the corresponding target follow spot object in real time, wherein the position is formed on the stage.
S104: and generating a control instruction of each real-time follow spot lamp corresponding to the target follow spot object according to the space coordinates of the real-time follow spot lamps and the coordinate information of the corresponding target follow spot object.
It is worth to be noted that, the stage light control device calculates the relative position information of the real-time follow spot light and the corresponding target follow spot object by using the spatial coordinates of the real-time follow spot light and the coordinate information of the corresponding target follow spot object, and determines the rotation angle of the real-time follow spot light according to the relative position information, and the control instruction corresponds to the rotation control of the real-time follow spot light. Specifically, as shown in fig. 2a, the stage light control device may use the laser radar as an origin, and perform vector included angle calculation by using a two-dimensional coordinate of the real-time follow spot light on a scanning plane of the laser radar and a two-dimensional coordinate of the target follow spot object on the scanning plane, so as to obtain a horizontal corner of the real-time follow spot light; as shown in fig. 2b, the spatial coordinates of the target light-following object and the spatial coordinates of the real-time light-following lamp are used to calculate the included angle of the spatial vector, so as to obtain the vertical rotation angle of the real-time light-following lamp, and the light-following of the real-time light-following lamp on the target light-following object is realized through two-stage control. The embodiment of the present application does not limit the specific control manner here. In addition, the control of the real-time follow spot lamp is aimed at the coordinate information of the target follow spot object acquired in real time, so that the real-time follow spot lamp can ensure that the spot formed by the stage can always cover the position of the coordinate information of the corresponding target follow spot object along with the movement of the target follow spot object.
S105: and sending the control instruction to the corresponding real-time follow spot lamp so that the real-time follow spot lamp responds to the received control instruction to adjust the angle, and the light spot formed by the real-time follow spot lamp on the stage covers the position of the coordinate information of the corresponding target follow spot object.
It should be noted that, after receiving the control instruction, the real-time follow lighting lamp correspondingly rotates in an angle, and aligns the light beam with the corresponding coordinate position of the target follow lighting object on the stage, so that the real-time follow lighting lamp forms a light spot on the stage, and the light spot also covers the position of the corresponding coordinate information of the target follow lighting object to complete the follow lighting of the target follow lighting object.
In the embodiment of the application, the method comprises the steps of receiving coordinate information of at least one candidate light-following object sent by at least one laser radar in real time, and confirming at least one target light-following object from the candidate light-following objects according to a current tracking mode; distributing a real-time follow spot for each target follow spot object according to the number and coordinate information of the target follow spot objects and pre-stored follow spot information; generating a control instruction of each real-time follow spot lamp corresponding to the target follow spot object according to the space coordinates of the real-time follow spot lamps and the coordinate information of the corresponding target follow spot object; sending the control instruction to the corresponding real-time follow spot lamp so that the real-time follow spot lamp can adjust the angle in response to the received control instruction, and the light spot formed by the real-time follow spot lamp on the stage can cover the position of the coordinate information of the corresponding target follow spot object; the target light following object is determined according to different current tracking modes, automatic tracking light following of the target light following object is achieved, and timeliness of light following and accuracy of the light following position are improved.
The embodiment of the present application provides another light following method, on the basis of the foregoing embodiment, further including:
s106: and displaying a distribution interface of the candidate light following objects according to the coordinate information.
It is worth mentioning that, in order to facilitate the user to select the target following spot object among the candidate following spot objects, the stage light control device may display a distribution interface of the candidate following spot objects. For example, the stage light control device may be provided with an interactive input device, e.g., a touch screen, as shown in fig. 3, which may present a profile of candidate light following objects to the user according to the received coordinate information, wherein each candidate light following object corresponds to one function selection entry, and the user may trigger the confirmation of one or more candidate light following objects as target light following objects by clicking on the one or more candidate light following objects. For another example, the stage light control device may also transmit the distribution map to a mobile terminal device of the user, such as a laptop, a mobile phone, etc., through wireless communication, and the user may complete the selection of the target follow-up object by operating on the mobile terminal device.
S107: receiving a tracking setting operation at a distribution interface, wherein the tracking setting operation is used for selecting a target light-following object and correspondingly setting a tracking mode from candidate light-following objects;
it should be noted that the distribution interface may further correspondingly present a plurality of tracking modes to facilitate the user to perform the tracking setting operation, for example, as shown in fig. 3, the touch screen may also present a plurality of tracking modes, such as a single tracking mode, a double tracking mode, a three-person tracking mode, and the like, and these tracking modes may also set the function selection entry, and the user may select different tracking modes according to different tracking requirements.
S108: in response to the tracking setting operation, the target tracking object confirmed by the tracking setting operation is newly created to the tracking mode.
It should be noted that steps S106 to S108 are subsequent to step S101, but are not in sequence with steps S102 to S105, and the application is not limited herein. In addition, the stage light control equipment can further select a certain tracking mode after a target user selects a target light-following object to complete tracking setting, so that the target light-following object can be bound to the selected tracking mode finally, for example, a distribution diagram of candidate light-following objects on a distribution interface comprises a first tracking mode, a second tracking mode and a third tracking mode, after the user selects the first tracking mode and the second tracking mode, the first tracking mode and the second tracking mode are bound, and when the subsequent double tracking mode is triggered, the first tracking mode and the second tracking mode can be automatically tracked.
The light following method can realize that a user can flexibly match the target light following object and the tracking mode according to the actual field requirements, enriches the light following modes, and is beneficial to the realization of multi-user and multi-mode light following tracking by simple operation of the user.
The embodiment of the present application provides another light following method, on the basis of the foregoing embodiment, further including:
s109: recording the coordinate information of each candidate light following object according to a time sequence to respectively generate corresponding motion tracks;
it should be noted that the laser radar periodically and continuously scans candidate light-following objects and outputs corresponding coordinate information, so that the stage light control device can collect the received coordinate information and record the motion track correspondingly generated by each candidate light-following object according to time sequence, and since the motion in the stage character unit time is small and single, the coordinate information meeting the characteristics can be regarded as the motion track belonging to the same candidate light-following object.
S110: and responding to the tracking setting operation, and associating the motion trail corresponding to the target light-following object confirmed by the tracking setting operation with a tracking mode.
It should be noted that step S110 and step S108 may be replaced with each other. In addition, the tracking setting operation associates the tracking mode with the motion track corresponding to the target light-following object, and then the stage light control device regards the received real-time coordinate information belonging to the motion track as the position update of the target light-following object, and further performs light-following tracking on the target light-following object according to the associated tracking mode. For example, as shown in fig. 4, after the user associates the movement track of the selected target light-following object with the single-person tracking mode at the first time, the stage light control device performs light-following tracking in the single-person tracking mode based on the real-time coordinate information belonging to the movement track.
The light following method can realize that the real-time light following lamp corresponding to each target light following object can rotate in a matching way according to the real-time coordinate information of the motion trail of the target light following object in the associated tracking mode, and timely and accurate tracking of the target light following object is realized.
On the basis of the foregoing embodiment, the distribution interface is further provided with a mode start-stop control corresponding to each tracking mode, where the mode start-stop control is used to switch the corresponding tracking mode between a trigger state and a silent state; the specific process of step S102 includes the following steps:
s102a: when receiving the trigger operation of the mode start-stop control currently in the silent state, switching the corresponding tracking mode to the trigger state, and switching other tracking modes currently in the trigger state to the silent state;
it should be noted that the tracking mode on the distribution interface corresponds to two states, namely a trigger state and a silent state, a user can select different states of the tracking mode through the mode start-stop control, select a certain tracking mode and trigger the tracking mode, so that the tracking mode is used as the current tracking mode, and the rest tracking modes should be correspondingly switched to the silent state. And because the tracking mode only corresponds to two states, namely a trigger state and a silence state, the tracking mode can be automatically switched to the other state after each trigger.
S102b: confirming a target light following object from the candidate light following objects according to the current tracking mode in the trigger state;
it is worth to be noted that the stage light control device may set a plurality of different tracking modes, and a user selects and adjusts the tracking mode according to actual needs of a scene, the tracking mode is realized by setting a target light-following object, the lidar takes all characters appearing on the stage as candidate light-following objects, and the light-following objects are often a small number of one or several people due to performance or ceremony needs, so that the tracking mode may determine the target light-following object from the candidate light-following objects, and the current tracking mode is the tracking mode in a triggered state.
S102c: when receiving the trigger operation of the mode start-stop control currently in the trigger state, switching the corresponding tracking mode to the silent state; and stopping processing the target light tracking object corresponding to the tracking mode in the silent state at present.
It should be noted that there is no precedence order between step S102a and step S102c, and the present application is not limited thereto. Since the tracking mode only corresponds to the two states of the trigger state and the silence state, the tracking mode is automatically switched to the other state after each trigger. The tracking mode originally in the trigger state should be correspondingly switched to the silent state after the user triggers the mode start-stop control, and light tracing is stopped.
In a specific implementation manner of the above embodiment, the stage lighting hole device sets two function selection entries of mute and trigger for three tracking modes, and selecting the trigger function selection entry enables the tracking mode, and disables other tracking modes already enabled, and selecting the mute function selection entry disables the tracking mode; for example, when a user puts a stage actor in place, three tracking modes are set for the performance, wherein the tracking mode I is to perform independent first pursuit, the tracking mode II is to perform ethylene propylene pursuit, and the tracking mode III is to perform first pursuit, second pursuit and third pursuit, so that when the user selects to trigger the tracking mode I, the stage light control equipment performs independent first pursuit; when the user selects the trigger tracking mode II according to the plot requirement, the stage light control equipment stops chasing the light to the first stage and starts chasing the light to the ethylene propylene; and when the stage does not need to track the light, the user selects to silence the current tracking mode II, and the stage light control equipment stops tracking the light of the ethylene propylene. The embodiment facilitates the user to silence and start the same tracking mode and also facilitates the user to switch different tracking modes.
On the basis of the foregoing embodiment, the specific process of step S103 includes the following steps:
s103a: confirming a projection coordinate on a reference plane according to spatial coordinate information in pre-stored follow spot light information;
it should be noted that, in the case where all the follow lamps are highly uniform, the relative distance between each follow lamp and the target follow light object can be represented by the distance between the projection coordinates of the follow lamp projected onto the scanning plane and the coordinates of the target follow light object.
S103b: and distributing the real-time follow spot light to each target follow spot object according to the distance between the projection coordinate and the coordinate information of the target follow spot object and the distance priority principle.
It should be noted that the stage light control device may determine which real-time follow spot is closest to the target follow spot object by calculating a distance between the projection coordinate and coordinate information of the target follow spot object, and then allocate the real-time follow spot to the target follow spot object.
In a specific implementation manner of the foregoing embodiment, the real-time follow lighting lamps may be directly and simply assigned in sequence according to the numbers of the follow lighting lamps, and although the implementation idea is simple, if a relatively distant follow lighting lamp is assigned to the target follow lighting object, the illumination of the follow lighting lamp may be weakened, and the accuracy of the follow lighting of the position of the target follow lighting object may be reduced. Then, with the scanning surface of the laser radar as a reference, projecting all real-time follow lighting lamps to the plane to obtain two-dimensional coordinates, calculating the distance between the real-time follow lighting lamps and the two-dimensional coordinates of the target follow lighting object, and allocating the real-time follow lighting lamp with the shortest distance to the target follow lighting object, so that the real-time follow lighting lamps are allocated according to the distance priority principle, and the real-time follow lighting lamp with the shortest distance is allocated to the target follow lighting object, so that the real-time follow lighting instantaneity and the accuracy of the follow lighting position are improved, and the follow lighting efficiency of the real-time follow lighting lamp is also improved.
The embodiment of the application provides another light following method, on the basis of the embodiment, the distribution interface further comprises a quick setting control, the tracking setting operation comprises a quick tracking operation, and the quick tracking operation is used for setting all candidate light following objects as target light following objects through one key of the quick setting control, so that a user can conveniently set all the candidate light following objects as the target light following objects while matching with performance effects, and the operation is convenient and efficient.
On the basis of the foregoing embodiment, the laser radar also transmits the static coordinates of the static object, and the distribution interface also displays the profile of the stage generated according to the static coordinates. Therefore, the stage light hole equipment can present the environment of the stage to the user, so that the user can conveniently and visually know the distribution condition of the candidate light-following object on the stage through the distribution interface, and the efficiency and the accuracy of selecting the target light-following object are improved.
