The following year, with PacTrans funding his team expanded that work with a project titled, &#8220;<a rel=\"noreferrer noopener\" href=\"http:\/\/depts.washington.edu\/pactrans\/research\/projects\/efficient-extraction-and-evaluation-of-complex-pavement-markings-from-mobile-laser-scan-data\/\" target=\"_blank\">Efficient Extraction and Evaluation of Complex Pavement Markings from Mobile Laser Scan Data<\/a>,&#8221; where they broadened the capabilities of the RoME tool to implement complex marking extraction (e.g., insertion lanes, arrows, text), improved noise filtering, deep learning-based classification, and rigorous tests on real-world data in various noise and road conditions. <\/p>\n\n\n\n<!--more-->\n\n\n\n<p>The team then leveraged PacTrans Technology Transfer Success Story funding to improve the research tool into a fully-functional prototype tool that can extract and classify various types of road markings. The important milestones of this supplemental funding include: (1) test and optimization, which evaluates the algorithm with various test data and optimizes the settings to improve the classification accuracy; (2) prototype development, which includes cleaning-up and packing the algorithms into the tool with a graphical user interface (GUI); and finally (3) training materials, which provides program user manual and videos of examples to promote the distribution of the tool via the website <a rel=\"noreferrer noopener\" href=\"http:\/\/learnmobilelidar.com\" target=\"_blank\">http:\/\/learnmobilelidar.com<\/a>.
