| description | The present invention relates to a Lidar sensor capable of removing background noise and a method of removing the noise thereof, wherein the Lidar sensor may include: a light reception part configured to sense reflected light reflected from an object; a weighting factor generation part configured to generate a weighting factor based on a sensing rate of the reflected light of the light reception part; a first histogram processing unit configured to perform histogram processing of a sensing signal of the light reception part based on the generated weighting factor, and extract data values greater than or equal to a first reference value from bins of the histogram to primarily remove noise; and a second histogram processing unit configured to accumulate the data values extracted from the first histogram processing unit to perform histogram processing, and extract accumulated data values greater than or equal to a second reference value from bins of the histogram, in which the data values are accumulated, to secondarily remove the noise. According to the present invention, even interference noise between the Lidar sensors can be removed.
