An object detection device includes a first sensor, a second sensor, a calculation range selection part and an estimation part. The first sensor transmits a radio frequency (RF) signal, receives the RF signal reflected from an object, and acquires a first measurement value about the object based on the received RF signal. The second sensor acquires a second measurement value about the object by sensing the physical characteristics different from the physical characteristics of the first sensor, from the object. The calculation range selection part sets a first reference range indicating an execution range of a first calculation for detecting a position of the object through a first algorithm, based on the second measurement value. The estimation part executes the first calculation only for the first reference range based on the first measurement value, and generates a first result value indicating the position of the object as an execution result of the first calculation. Therefore, the present invention is capable of maintaining object detection performance and accuracy without causing a deterioration therein.
객체 검출 장치는 제1 센서, 제2 센서, 연산 범위 선택부 및 추정부를 포함한다. 제1 센서는 RF(Radio Frequency) 신호를 송신하고, 객체로부터 반사된 RF 신호를 수신하며, 수신된 RF 신호에 기초하여 객체에 대한 제1 측정 값을 획득한다. 제2 센서는 객체로부터 제1 센서와 다른 물리적 특성을 센싱하여 객체에 대한 제2 측정 값을 획득한다. 연산 범위 선택부는 제2 측정 값에 기초하여, 제1 알고리즘을 이용하여 객체의 위치를 검출하기 위한 제1 연산의 수행 범위를 나타내는 제1 기준 범위를 설정한다. 추정부는 제1 측정 값을 이용하여 제1 기준 범위에 대해서만 제1 연산을 수행하며, 제1 연산의 수행 결과로서 객체의 위치를 나타내는 제1 결과 값을 생성한다.
