LiDAR Data Processing with Python: Turn 3D Laser Scanner Point Clouds into Detailed Spatial Maps for Autonomous Mobile Robots - Tapa blanda

LiDAR Data Processing with Python (Paperback)

Paperback. Condición: new. Paperback. Turn raw 3D laser scans into clean, useful maps that autonomous mobile robots can understand.A LiDAR sensor can capture thousands or millions of distance measurements, but a cloud of points is not automatically a robot-ready map. Raw scans must be inspected, cleaned, transformed, aligned, segmented, and converted into spatial information that navigation software can use.LiDAR Data Processing with Python teaches that complete workflow step by step. Using Python, NumPy, Open3D, laspy, SciPy, Matplotlib, scikit-learn, optional PDAL tools, and ROS 2 concepts, you will learn how to turn point clouds into practical occupancy, elevation, and traversability maps for autonomous mobile robots.This beginner-friendly guide will help you: Understand how LiDAR sensors measure distance and produce point cloudsWork with X, Y, and Z coordinates, intensity, returns, timestamps, classifications, and colour attributesPrepare a clean Python workspace for point-cloud processingLoad, inspect, and convert PCD, PLY, LAS, LAZ, XYZ, CSV, and NumPy point-cloud filesRead large LiDAR files safely without exhausting memoryVisualise point clouds from multiple viewpoints using Open3D and MatplotlibRemove invalid coordinates, distant points, robot-body points, noise, and outliersUse voxel, uniform, random, statistical, radius, and intensity-based filtering methodsWork with coordinate frames, translation, rotation, transformation matrices, and sensor-to-robot conversionsDetect ground surfaces, slopes, ramps, and height above groundSegment floors, walls, ceilings, pallets, boxes, and other objectsGroup points with DBSCAN and measure objects with bounding boxesAlign and combine multiple scans using registration and ICP conceptsCreate two-dimensional occupancy grid maps for robot navigationBuild elevation and traversability maps that identify slopes, rough ground, curbs, steps, and unsafe terrainProcess recorded and live robot LiDAR data safelyConnect processed clouds and maps to ROS 2 navigation workflowsImprove performance with chunking, tiling, reusable functions, configurable pipelines, and batch jobsBuild a complete robot-ready mapping pipeline as the final projectThe book builds one practical workflow rather than disconnected demonstrations. You will begin by inspecting individual point-cloud files, then progress through cleaning, transformation, ground detection, segmentation, registration, occupancy mapping, elevation mapping, traversability analysis, ROS 2 publishing, and complete pipeline organisation.No LiDAR sensor is required to begin. Sample files support the core exercises, while live-data and robot-navigation sections can be explored later with suitable hardware and ROS 2 software.The focus is practical robot mapping. You will learn why coordinate frames, units, thresholds, timestamps, map resolution, obstacle expansion, and validation matter before a robot is allowed to trust the resulting map.Build cleaner point-cloud workflows, create better spatial maps, and prepare LiDAR data for safer autonomous mobile robot navigation.
