  • Patent number: 11380226
    Abstract: The present invention provides a method of setting light emission control of each light emission tool in an area more easily. The method of setting light emission control of each tool in an area of the present invention includes: a light emitting step of transmitting a freely-selected ID signal (Sn) to a plurality of tools in an area and emit light in response to receipt of corresponding ID signals to cause a tool (En) that has received the signal (Sn) to emit light; an imaging step of acquiring a light emission image (En) of the area after the signal (Sn) has been transmitted; a determining step of determining a position of the tool (En) that emitted light in the area based on the image (En); and a storing step of storing the position of the tool (En) in the area and the corresponding signal (Sn).
