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:
 a flight device comprising:
 a projector; 
 a controller; and 
 a flight controller, 
   wherein the projector is configured to emit a light,   wherein the flight controller is configured to control flight of the flight device,   wherein the controller is configured to control the projector to, if an irradiation target to be irradiated is detected in an image capturing a monitoring region, emit the light as a guidance light to the irradiation target; and   a flying object configured to fly toward the guidance light.   
     
     
         2 . The irradiation system according to  claim 1 , wherein the flight device further includes at least on slave device,
 wherein the slave device is a detachable device including a function for emitting the guiding light.   
     
     
         3 . The irradiation system according to  claim 1 , wherein the controller is configured to control the projector to emit the guidance light toward an estimated position of the irradiation target. 
     
     
         4 . An irradiation method comprising:
 detecting, by at least one computer, an irradiation target to be irradiated in an image capturing a monitoring region; and   controlling, by the at least one computer, a projector to, if the irradiation target is detected, emit a light as a guidance light to the irradiation target,   wherein the guidance light guides a flying object.   
     
     
         5 . The irradiation method according to  claim 4 , the method further comprising:
 controlling, by the at least one computer, the projector to emit the guidance light toward an estimated position of the irradiation target.   
     
     
         6 . 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 an image capturing a monitoring region; and   controlling a projector to, if the irradiation target is detected, emit a light as a guidance light to the irradiation target,   wherein the guidance light guides a flying object.   
     
     
         7 . The non-transitory program storage medium according to  claim 6 , wherein the process further comprises:
 controlling the projector to emit the guidance light toward an estimated position of the irradiation target.
