THREE-DIMENSIONAL COORDINATE AUTOMATIC MEASUREMENT SYSTEM IN VOICE TRACKING AUTOMATIC SIGHTING SYSTEM

摘要

PURPOSE: To avoid direct operation by the operator or a participant and to allow the system to flexibly cope with number of participants and installed location or the like with respect to the 3-dimension coordinate automatic measurement system in the voice tracking automatic sighting system in which coordinate data of a seat position of an utterance party corresponding to the detection of a voice signal are used to calculate an utterance party and a distance of a camera thereby controlling the camera. ;CONSTITUTION: A transmitter 2 used to transmitting a specific radio signal is fitted respectively to a microphone 1 provided corresponding to each seated position of a conference participant, a camera 4 is fitted to a fixed position in front of entire seats and at least three 2-dimensional receivers 3A-3C are arranged on a face in the vertical direction opposite to the seats at three positions fixed to the camera 4 respectively. A reception angle of a reception sinal is measured by a reception angle measurement sections 5A-5C by controlling each receiver and the coordinate of the transmitter is obtained by calculation through the use of the measured reception signal, the reception angle and the coordinate of the receiver to obtain the coordinate of each participant.;COPYRIGHT: (C)1994,JPO&Japio
