Light irradiation device and light irradiation system

Abstract

A light irradiation device includes: at least one imaging means that images a monitoring region to continue to accurately irradiate a moving target with light; at least one projection means that irradiates the monitoring region with signal light; a control means that controls the imaging means to image the monitoring region and controls the projection means to emit the signal light; at least one propeller that moves the own device in the air; and a flight control means that controls flight of the own device by controlling the propeller, the control means controlling, when recognizing a light irradiation target to be irradiated with the signal light on image data imaged by the imaging means, the projection means to emit the signal light toward the light irradiation target.

1 . An irradiation system comprising:
 at least one processor configured to:
 detect an irradiation target to be irradiated in a captured image; and 
 control a projector to emit a light in such a way that, if the irradiation target moves in a direction away from a monitoring region, the projector does not emit the light even if the irradiation target is detected, and to otherwise emit the light if the irradiation target is detected. 
   
     
     
         2 . The irradiation system according to  claim 1 , wherein the projector is included in a flight device, and
 wherein at least one processor is further configured to:
 while detecting the irradiation target which is moving, control a flight of the flight device to follow the irradiation target, and 
 control the projector to keep emitting the light. 
   
     
     
         3 . The irradiation system according to  claim 1 , wherein the at least one processor is configured to, if a plurality of irradiation targets are detected moving toward a direction other than the direction away from the monitoring region, control the projector to emit the light to the plurality of the irradiation targets. 
     
     
         4 . The irradiation system according to  claim 1 , wherein the at least one processor is configured to control the projector to emit the light to the irradiation target after adjusting an emit timing using a predetermined condition. 
     
     
         5 . An irradiation method comprising:
 detecting, by at least one processor, an irradiation target to be irradiated in a captured image; and   controlling, by the at least one processor, a projector to emit a light in such a way that, if the irradiation target moves in a direction away from a monitoring region, the projector does not emit the light even if the irradiation target is detected, and to otherwise emit the light if the irradiation target is detected.   
     
     
         6 . The irradiation method according to  claim 5 , the method further comprising:
 while detecting the irradiation target which is moving, controlling a flight of the flight device to follow the irradiation target; and   controlling the projector to keep emitting the light.   
     
     
         7 . The irradiation method according to  claim 5 , the method further comprising:
 if a plurality of irradiation targets are detected moving toward a direction other than the direction away from the monitoring region, controlling, by the at least one processor, the projector to emit the light to the plurality of the irradiation targets.   
     
     
         8 . The irradiation method according to  claim 5 , the method further comprising:
 controlling the projector to emit the light to the irradiation target after adjusting an emit timing using a predetermined condition.   
     
     
         9 . A non-transitory program storage medium storing a computer program that, when executed, causes a computer to execute a process comprising:
 detecting an irradiation target to be irradiated in a captured image; and   controlling a projector to emit a light in such a way that, if the irradiation target moves in a direction away from a monitoring region, the projector does not emit the light even if the irradiation target is detected, and to otherwise emit the light if the irradiation target is detected.   
     
     
         10 . The non-transitory program storage medium according to  claim 9 , wherein the process further comprises:
 while detecting the irradiation target which is moving, controlling a flight of the flight device to follow the irradiation target; and   controlling the projector to keep emitting the light.   
     
     
         11 . The non-transitory program storage medium according to  claim 9 , wherein the process further comprises:
 if a plurality of irradiation targets are detected moving toward a direction other than the direction away from the monitoring region, controlling the projector to emit the light to the plurality of the irradiation targets.   
     
     
         12 . The non-transitory program storage medium according to  claim 9 , wherein the process further comprises:
 controlling the projector to emit the light to the irradiation target after adjusting an emit timing using a predetermined condition.
