OBJECT POSITION DETERMINING SYSTEM AND CHAIR POSITION DETERMINING SYSTEM

An object position determining system, applied to a vehicle, comprising: at least one light source, configured to emit light; at least one optical sensor, configured to sense optical data generated based on reflected light of the light; and a processing circuit, configured to compute distance information between the optical sensor and at least one object which generates the reflected light, and real time vehicle orientation data; wherein the processing circuit determines at least one position of the object according to the distance information and the real time vehicle orientation data.
