Abstract

The invention provides a laser ranging data processing method based on multi-feature analysis, which can comprehensively improve the quality and stability of laser ranging data. Comprising the following steps: S1, carrying out pulse width interception on a laser signal, and then carrying out signal preprocessing on the intercepted pulse width signal; s2, the preprocessed pulse width signal reaches a measured object through a variable attenuation piece, the reflected signal returns to a distance measuring point after passing through the variable attenuation piece again, and a relation curve between the pulse width signal and an attenuation coefficient is obtained according to the pulse width change so as to determine the pulse width law; and S3, acquiring continuous and adjacent multi-frame ranging data, comparing a plurality of results of the to-be-measured ranging data with a preset judgment threshold so as to perform multi-group credibility evaluation, and after fusing a plurality of groups of credibility data, taking the ranging result with the highest comprehensive credibility as final output ranging data.
