The present invention provides a method for removing noise and a laser scanning device for hazardous chemical storage. The method includes: determining a reference data point in the displayed data points; obtaining the distance between the noise point in the data point and the reference data point; Determining the noise points in the data points whose distance from the reference data point is greater than the first distance value as the first type of noise points; and determining the distance between the data points and the reference data point is smaller than the second distance value The noise point is determined as the second type of noise point, wherein the first distance value is greater than the second distance value; the first type of noise point is removed, and the second type of noise point is removed to obtain the target data point. The embodiment of the present invention can make the obtained measurement result more accurate.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a method for removing noise and a laser scanning device for storing hazardous chemicals. Background technique [0002] With the development of laser technology, laser technology has also been widely used in social life, for example, it can be used to detect the distance between various hazardous chemicals in warehouses where hazardous chemicals are placed. In practical applications, there are many noise points in the data points obtained by laser scanning, so that the error of the measurement results obtained from the data points is large. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present invention is to provide a method for removing noise and a laser scanning device for hazardous chemical storage, which solves the problem that there are many noises in the data points obtained by laser scanning, so that the error of the measurement results ...
