Abstract
The present invention relates to a Lidar sensor capable of removing background noise and a method of removing the noise of the same, and the Lidar sensor may include: a light reception part configured to sense reflected light reflected from an object; a weight generation part configured to generate a weight 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 weight, and extract data values greater than or equal to a first reference value from bins of the histogram to firstly 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.
