Traditionally, walk error must be suppressed by some time discrimination methods with extremely complex electronic circuits and high costs. In this paper, we propose a compact and flexible method for reducing walk error and achieving distance-intensity imaging. A single threshold comparator and commercial time digital converter chip are designed to measure the laser pulse\u2019s time of flight and pulse width. In order to obtain first-class measurement accuracy, we designed a specific pulse width correction method based on the Kalman filter to correct the laser recording time, significantly reducing the ranging walk error by echo intensity fluctuation. In addition, the pulse width obtained by our method, which is a recording of the laser intensity, is conducive to target identification. The experiment results verified plane point clouds of various targets obtained by the proposed method with a plane flatness less than 0.34. The novel contribution of the study is to provide a highly integrated and cost-effective solution for the realization of high-precision ranging and multi-dimensional detection by pulsed LiDAR. It is valuable for realizing multi-dimension, outstanding performance, and low-cost LiDAR.<\/jats:p>","DOI":"10.3390\/rs14030507","type":"journal-article","created":{"date-parts":[[2022,1,23]],"date-time":"2022-01-23T20:34:40Z","timestamp":1642970080000},"page":"507","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Research of Distance-Intensity Imaging Algorithm for Pulsed LiDAR Based on Pulse Width Correction"],"prefix":"10.3390","volume":"14","author":[{"given":"Shiyu","family":"Yan","sequence":"first","affiliation":[{"name":"National Key Laboratory of Tunable Laser Technology, Harbin Institute of Technology, Harbin 150001, China"},{"name":"Geling Institute of AI and Robotics, Shenzhgen 518063, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0620-6494","authenticated-orcid":false,"given":"Guohui","family":"Yang","sequence":"additional","affiliation":[{"name":"Harbin Institute of Technology, School of Electronic and Information Engineering, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingyan","family":"Li","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Tunable Laser Technology, Harbin Institute of Technology, Harbin 150001, China"},{"name":"Geling Institute of AI and Robotics, Shenzhgen 518063, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4755-6167","authenticated-orcid":false,"given":"Yue","family":"Wang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Tunable Laser Technology, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhui","family":"Wang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Tunable Laser Technology, Harbin Institute of Technology, Harbin 150001, China"},{"name":"Geling Institute of AI and Robotics, Shenzhgen 518063, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1016\/j.isprsjprs.2013.06.002","article-title":"Backscattering of individual LiDAR pulses from forest canopies explained by photogrammetrically derived vegetation structure","volume":"83","author":"Korpela","year":"2013","journal-title":"ISPRS J.
