Person location detection apparatus and air conditioner
First Claim
1. A person location detecting apparatus comprising:
- a projection light;
a light emitting section for radiating the projection light;
a TOF (Time Of Flight) method distance image sensor for receiving a reflected light from a room space of the projection light to output distance information in accordance with a distance to an object in the room space from each of a plurality of light receiving sections;
a distance change detecting section for detecting a distance change to the object in the room space based on the distance information from the TOF method distance image sensor; and
a person distinguishing section for distinguishing a person by identifying a shape of a detected distance change area to detect a direction and distance to the distance change area that is identified as a shape of a person as a location of a person,wherein the distance change detecting section measures a distance to the object in the room space in real time using the TOF method distance image sensor, calculates a differential value of the measured distance with respect to time, and determines that the measured distance is in a balanced state when the differential value becomes asymptotic to zero.
