摘要： A LIDAR sensor apparatus and a control method thereof. The LIDAR sensor apparatus includes a transmitter configured to transmit a laser, first and second receivers each configured to receive a reflected signal reflected from an object after the laser is transmitted through the transmitter, a control unit configured to calculate first and second distances by performing signal processing on first and second signals received from the first and second receivers after the laser is transmitted through the transmitter, and to calculate an intermediate distance by performing signal processing on an overlapping signal obtained by overlapping the first and second signals, and an output unit configured to output the first and second distances and the intermediate distance calculated by the control unit.
