Abstract
An infrared positioning apparatus comprises a plurality of infrared diodes, a plurality of amplifying units, a plurality of converting units and a positioning unit. The plurality of infrared diodes is configured to detect at least one infrared signal. The plurality of amplifying units are configured to amplify the at least one infrared signal for obtaining at least one amplified signal. The plurality of converting units are configured to convert the at least one amplified signal for obtaining at least one strength value of the at least one amplified signal. The positioning unit is configured to obtain the emitting direction of the at least one infrared signal in accordance with the at least one strength value of the at least one amplified signal.
