Apparatus and method for detecting location of moving body, lighting apparatus, air conditioning apparatus, security apparatus, and parking lot management apparatus
An apparatus and method for detecting the location of a moving body. The apparatus may include a speaker configured to intermittently generate a pulse signal to a detection space and a microphone array configured to obtain a reflected sound of the pulse signal that is generated in the detection space. The location of a moving body is estimated by extracting a change of a sound field from the reflected sound. The present invention can be applied to an apparatus for detecting a moving body without any side effect because the location of a moving body can be accurately detected up to an angle and distance. Furthermore, the present invention can be applied to various application apparatuses, such as a lighting apparatus, an air conditioning apparatus, a security apparatus, and a parking lot management apparatus because there is no problem in health and there is no side effect in application.
