Abstract
Disclosed is an apparatus for detecting a linear object, the apparatus including: an ultrasonic sensor including first, second, third and fourth ultrasonic sensor units, each of which is configured to transmit a signal toward an object and receive signals of direct waves and indirect waves reflected from the object; an ultrasonic signal preprocessor configured to preprocess the direct waves and indirect waves received in each of the first, second, third and fourth ultrasonic sensor units and detect a direct wave time-of-flight (TOF) and an indirect wave TOF; a linear object identifier configured to identify a linear object based on at least one of the direct wave TOF and the indirect wave TOF; and a controller configured to control braking of a vehicle based on the linear object.

An apparatus for detecting a linear object, the apparatus comprising:
- an ultrasonic sensor comprising first, second, third and fourth ultrasonic sensor units, each of which is configured to transmit a signal toward an object and receive signals of direct waves and indirect waves reflected from the object;
- an ultrasonic signal preprocessor configured to preprocess the direct waves and indirect waves received in each of the first, second, third and fourth ultrasonic sensor units and detect a direct wave time-of-flight (TOF) and an indirect wave TOF;
- a linear object identifier configured to identify the linear object based on at least one of the direct wave TOF and the indirect wave TOF;
- and
- a controller configured to control braking of a vehicle based on the linear object.
A method of detecting a linear object, the method comprising:
- by each of first, second, third and fourth ultrasonic sensor units, transmitting a signal toward an object and receiving signals of direct waves and indirect waves reflected from the object;
- preprocessing the direct waves and indirect waves received in each of the first, second, third and fourth ultrasonic sensor units to detect a direct wave time-of-flight (TOF) and an indirect wave TOF;
- identifying the linear object based on at least one of the direct wave TOF and the indirect wave TOF;
- and
- controlling braking of a vehicle based on the linear object.
