Detailed Description
The present application will be described in detail below with reference to the accompanying drawings 1-6 and examples.
Referring to fig. 1, an outdoor laser projection method includes the steps of:
s1, dividing a projected surface of a target building 1 into a plurality of projection subareas 2 by a controller according to a preset picture.
And S2, the controller sends control information to the preset laser device 3 to enable the laser device 3 to execute laser projection.
And S3, the controller receives the projection effect feedback information of each projection partition 2.
And S4, the controller analyzes the projection effect corresponding to the projection partition 2 according to the projection effect feedback information.
And S5, if the projection effect of the projection partition 2 does not meet the preset projection requirement, the controller sends adjustment information to the laser device 3 to adjust the light emitting strategy.
The outdoor laser projection method provided by the application needs to arrange the laser device 3 at the periphery of the target building 1, and the laser emitted by the laser device 3 is projected to the projected surface of the target building 1 to form a picture related to light.
The projected surface refers to an outer wall of the target building 1 that can reflect light, and may be one surface or more than one surface of the target building 1. The location where the laser device 3 is located may be a projected face-to-face location such as a rooftop of a partition building or a ground square of the target building 1.
The laser device 3 operates according to a control signal sent by the controller. The laser device 3 may comprise one or more lasers, which may be of the scanning type and/or of the diffraction type. The laser may have a plurality of light emitting devices.
Wherein, take a scanning laser as an example:
after the laser control module built in the scanning laser receives the control signal from the controller, the laser is emitted outwards through the light-emitting device built in the scanning laser, and the color, the frequency and the brightness of the emitted laser can be adjusted according to the control signal.
And the operation of a scanning galvanometer built in the scanning laser, namely the corresponding execution of the x-axis motor and the y-axis motor on the scanning galvanometer is carried out according to the control signal. When the two motors scan, the emitting path of the laser can be changed and reflected to the projection surface by combining with the reflecting mirror on the stator of the motor, so that the plane coordinate system is established on the projection surface, various pictures can be drawn on the coordinate system, and the drawing speed is very high and exceeds the identification capability of human eyes, so that the projection surface can integrally display pictures related to light. The controller can be realized by combining a computer with a cloud server.
The light-related picture includes, but is not limited to, a picture in which a laser is emitted to form a character, a shape, a pattern, and/or a dynamic figure.
Taking a computer as an example of a controller, a worker designs a picture in advance on editing software preinstalled in the computer and divides the picture, after the computer outputs a corresponding control signal, the computer sends the control signal to the laser device 3 in a wired or wireless mode, and the laser device 3 performs laser projection on a projected surface of the target building 1.
Because the range of the projected surface of the target building 1 is large, and the scale of the combined picture is also large, the controller divides the projected surface of the target building 1 into a plurality of projection subareas 2 according to the preset picture. Correspondingly, the number of the corresponding lasers is set according to the number of the projection subareas 2. The corresponding projection is beneficial to making the picture of each projection subarea 2 richer and more gorgeous.
In addition, in the application, a sensor needs to be preset at the position of each projection partition 2 on the target building 1, and the sensor is used for obtaining corresponding projection effect feedback information according to the received picture of the projection partition 2 and feeding the projection effect feedback information back to the controller in a wired or wireless manner. Laser effects referred to herein include, but are not limited to: a lost picture corresponding to the projection partition 2, a picture error corresponding to the projection partition 2, and/or a blurred picture corresponding to the projection partition 2. The sensor may adopt a light sensor collector, the light sensor collector may be installed inside the target building 1, and the installation position may be a glass curtain wall corresponding to the projection partition 2. The number of photoreceptors per projection zone 2 may be one or more.
After the controller receives the projection effect feedback information of each projection partition 2, the information is analyzed, and if the information is analyzed, the information is obtained
The projection effect corresponding to the projection partition 2 does not meet the preset projection requirement, for example: if the situation that a picture is lost in one or more than one projection partition 2 is analyzed, and at the moment, the projection requirement that the picture is complete is not met, the controller sends out adjustment information to the laser equipment 3, so that the laser equipment 3 automatically adjusts a light emitting strategy according to the feedback situation, and the projection problem is solved: if some part of the picture is lost, the light emitting of the laser equipment 3 is adjusted to change the whole picture, so that the laser projection beautification can be ensured to be continuous and effective, the lighting effect is not influenced by problems, and the effect is more stable.
The laser projection system is used for arranging the laser equipment 3 at the periphery of a target building 1 to perform laser projection, lamps do not need to be installed on the outer wall of the building, workload caused by the installation of the lamps at high altitude is reduced, and the implementation is safer. And the picture formed by laser projection is more various and gorgeous.
Referring to fig. 2, taking the example that the projection receiving surface of the target building 1 is divided into 4 projection zones 2, in this embodiment, the specific step that the controller receives the projection effect feedback information of each projection zone 2 includes: and S31, receiving projection effect feedback information sent by a sensor preset in each projection partition 2 by the controller according to a certain period. Projection effect feedback information includes, but is not limited to: no laser light is sensed, the laser light is weak, or the laser light is fuzzy.
For example, sensors are arranged in all 4 projection subareas 2, the sensors respectively sense laser projection effects corresponding to the projection subareas 2, when the sensor of one of the projection subareas 2 does not sense laser light, corresponding projection effect feedback information is generated and sent to the controller in a data packet mode according to a cycle of sending every minute, and therefore the controller knows that one projection subarea 2 does not project laser light through the projection effect feedback information and timely adjusts a light emitting strategy. In addition, the controller can also adopt a mode of receiving projection effect feedback information in real time, so that the reaction speed is improved.
The method provided by the application further comprises the following steps: and S6, if the projection effect feedback information of each projection partition 2 is received, the controller sends out shutdown information to the laser equipment 3 so as to stop the laser equipment 3 from running. At this moment, the laser emitted by the laser device 3 is not projected on the projection surface, and the controller automatically controls the laser device 3 to be closed, so that the debugging, problem repairing or device replacement of workers are facilitated.
The method provided by the application further comprises the following steps: and S7, if the rainfall trigger information derived from the rainfall sensor is received, the controller sends closing information to the laser device 3. Whether the condition of raining exists in the open air is timely responded to through the rainfall sensor, when the situation that the rainfall is monitored, the rainfall sensor outputs rainfall trigger information, and the controller receives the rainfall trigger information and then timely controls the laser equipment 3 to stop running, so that the laser equipment 3 is protected.
The method provided by the application further comprises the following steps: and S8, if wind power triggering information derived from the wind power sensor is received, the controller sends closing information to the laser device 3. Therefore, the wind sensor can timely sense whether strong wind exists outdoors, when the situation that the strong wind blows at present is monitored, the wind sensor outputs wind force trigger information, and the controller timely controls the laser equipment 3 to stop running after receiving the wind force trigger information, so that the laser equipment 3 is protected.
In this embodiment, the adjustment information is specifically standby laser operation information, the preset projection requirement is that all projection partitions 2 receive laser light, and if the projection effect of the projection partition 2 does not meet the preset projection requirement, the controller sends the adjustment information to the laser device 3, so as to adjust the light-emitting strategy, the specific steps include: and S51, if the situation that one of the projection subareas 2 does not receive the laser does not meet the preset projection requirement, the controller sends out adjustment information to a standby laser in the laser device 3 so as to enable the standby laser to start running and continue to perform laser projection to the projection subarea 2 which does not receive the laser. The controller continuously analyzes the picture effect of each projection subarea 2 according to the projection effect feedback information, if the controller knows that one projection subarea 2 in the 4 projection subareas 2 has no laser projection, the result of picture loss of the projection subarea 2 is obtained, at the moment, the controller can drive the standby laser to operate and send standby laser operation information to the standby laser, the standby laser can carry out compensation emission on the projection subarea 2 with the picture lost according to the requirement of the controller, the whole picture is effectively ensured to be completely recovered, the laser projection beautification can be ensured to be continuously and effectively, and the light effect is not influenced by problems.
Referring to fig. 3, as another embodiment, if the projection effect of the projection partition 2 does not meet the preset projection requirement, the specific step of sending adjustment information to the laser device 3 to adjust the light exit strategy includes: and S51, if the condition that one of the projection subareas 2 does not receive the laser is that the preset projection requirement is not met, the failure of the laser corresponding to the projection subarea 2 in the laser equipment 3 is proved. The controller re-partitions the projected surface of the target structure 1 into projection zones 2. Specifically, the number of projection sections 2 is the same as the number of lasers in the laser device 3 capable of normal operation. According to the subdivided projection subarea 2, the controller sends adjustment information to the laser equipment 3, so that the laser equipment 3 can readjust the picture formed by projecting the laser on the projection surface. Therefore, the laser emitted by the laser device 3 is correspondingly adjusted, and the projected surface is quickly re-projected to form a complete picture. Ensure that laser projection beautifies and can also last effectively, reduce the influence of problem to the light effect.
Further, at this time, the sensor is correspondingly readjusted according to the repartitioned projection partition 2, and the readjustment method may be: the sensors are regrouped according to the reclassified projection subareas 2, and each projection subarea 2 is ensured to have at least one sensor for subsequent effect feedback.
As another embodiment, if the projection effect of the projection partition 2 does not meet the preset projection requirement, the specific step of sending adjustment information to the laser device 3 to adjust the light exit strategy includes: s51, if the situation that one of the projection subareas 2 does not receive the laser is that the preset projection requirement is not met, it is proved that one of the laser devices 3 corresponding to the projection subarea 2 fails, and the controller controls a plurality of laser devices capable of normally operating in the laser device 3 to project the projection subareas 2 one by one in a circulating trotting horse lamp mode.
With reference to fig. 4, the form of the revolving trotting horse-light specifically refers to: for example, the projection surface is divided into 4 projection subareas 2, namely an area A, an area B, an area C and an area D, when the area A does not receive laser, and the controller knows by receiving projection effect response information of the area A. At the moment, the controller obtains that the projection effect of the projection partition 2 does not meet the preset projection requirement, the controller controls the laser device which originally irradiates the D area in the laser device 3 to be adjusted to irradiate the A area, and the laser device which originally irradiates the C area is adjusted to irradiate the D area; the laser irradiating area B is adjusted to irradiate area C, and the laser irradiating area A is controlled again to irradiate area B, so that the adjustment is repeated. The operation ensures that the light change is displayed circularly by the projection surface, so that the laser projection beautification can be continued and effective, and the influence of faults on the light effect is reduced. And once the form of circulating trotting horse lamp is formed, the staff can know that a certain laser has a fault failure in time, and then can follow up the laser to repair or replace in time.
Or S51, if the condition that more than one projection subarea 2 does not receive the laser does not meet the preset projection requirement, the failure of a plurality of lasers corresponding to the projection subareas 2 in the laser equipment 3 is proved, and the controller controls the lasers which can normally run in the laser equipment 3 to perform reciprocating projection between the original projection subarea and the adjacent laser-free projection subarea.
Referring to fig. 5, the reciprocating projection specifically refers to: for example, the projection surface is divided into 4 projection zones 2, namely, a zone A, a zone B, a zone C and a zone D, when the zone A and the zone C do not receive the laser, and the controller knows by receiving the projection effect response information of the zone A. At this time, the controller obtains that the projection effect of the projection partition 2 does not meet the preset projection requirement, and the controller controls the laser device which originally irradiates the area B in the laser device 3 to be adjusted to perform reciprocating projection in the area A and the area B. And simultaneously, the controller controls the laser device 3 which originally irradiates the D area to be adjusted to perform reciprocating projection in two areas of the C area and the D area. The operation ensures that the light change is displayed circularly by the projection surface, so that the laser projection beautification can be continued and effective, and the influence of faults on the light effect is reduced. And once a circularly reciprocating mode is formed, a worker can timely know that a plurality of lasers have fault failures, and can timely follow the lasers for maintenance or replacement.
