    Abstract: Disclosed is a method of estimating a position by a position estimation system. The method includes generating a time-synchronization signal for position determination using a genetic algorithm, embedding the generated time-synchronization signal in an audio signal, and replaying the audio signal embedded with the time-synchronization signal through a speaker, receiving the audio signal embedded with the time-synchronization signal in a microphone, calculating a time delay value of the time-synchronization signal embedded in the received audio signal, and estimating a position of the microphone based on the calculated time delay value.

    Abstract: Disclosed herein a method of removing a point cloud outlier and an apparatus implementing the method. The method includes: arranging a point cloud obtained from a laser scanner along at least a first direction; selecting, neighboring first-axis points, between which a separation degree satisfies an inspection start threshold condition, as a first leading-side representative point and a first trailing-side representative point; selecting a first leading-side outlier candidate and a first trailing-side outlier candidate based on a first leading-side separation degree and a first trailing-side separation degree; and determining the first leading-side outlier candidate and the first trailing-side outlier candidate as a first outlier point, when the number of the outlier candidates satisfies an allowable threshold condition.
