This application relates to a location tracking device and method using a feature matching. The location tracking device may include a sensor, a camera, and a controller. The sensor is provided in a predetermined object and collects sensing information including at least one of speed, direction, gravity, and acceleration of the object. The camera is provided in the predetermined object and collects image information by capturing an image. The controller calculates an initial fundamental matrix (F) by using the collected sensing information and calibration information of the camera, detects feature points of the image information, performs a feature matching in a fundamental matrix (F) by combining the initial fundamental matrix and the feature points, and tracks a location of the object by using a result of the feature matching.

Location tracking device and method using feature matching

Disclosed are an apparatus and a method for detecting a broadcasting signal. The signal detecting apparatus according to the exemplary embodiment of the present invention includes: a reference signal generator outputting a reference signal acquired by performing a correlation calculation between a current sample and a previous sample of a received signal which is an FM signal or a digital radio mondiale plus (DRM+) signal and then normalizing a result of the correlation calculation; and a discriminator detecting a maximum value of the reference signal and judging that the received signal is the FM signal when the maximum value of the reference signal is more than a predetermined threshold.
