This work presents a machine learning based study on people detection using 2D Laser Range Finders (LRFs) combined with deep learning methodologies, aimed at enhancing mobile robot capabilities in various environmental conditions. The study introduces a novel integration of a monocular camera with an LRF on a mobile robot to improve the accuracy and e✣ciency of detecting and tracking people. By employing deep learning models such as CenterNet, the system leverages both image and 2D range data to facilitate automatic labeling of datasets, crucial for training robust classi✜cation algorithms. In order to achieve the best classi✜er, two experimental studies are introduced in this work.  \nThe former is carried out in a simulated environment and the latter in real-world, o✣ce-like environments. In simulations, various machine learning models are trained and evaluated, showing signi✜cant results in distinguishing human legs from other objects. The transition to realworld testing underscores the challenges and adaptations necessary to achieve high accuracy and reliability in dynamic settings. The XGBoost model emerged as the most e✛ective classi✜er in our study, achieving the highest scores in accuracy, precision, recall, and F1-score, outperforming other methods across these key metrics. This work aims to advance the ✜eld of 2D LRF based people detection and also proposes a solution for real-time applications, balancing precision and computational e✣ciency.  \nExperimental results from both simulated and real-world environments demonstrate the system✬s e✛ectiveness.  \nKeywords: People detection ➲ Deep learning ➲ Machine learning ➲ 2D LRF  \n1 Introduction  \nMobile robots rely on detecting and tracking people for applications like HumanRobot Interaction (HRI), navigating crowded spaces, and safety in shared environments [20] .

Despite the advantages of vision systems, 2D Laser Range Finders (LRFs) are favored in social and service robots for their reliability and wide ✜eld of view, overcoming the limitations of vision sensors in adverse conditions [4] .  \nDetecting people using 2D laser technologies can be achieved through various approaches, as outlined in the survey conducted by M. Sharif [22] . Some techniques directly process laser measurements individually as inputs for supervised machine learning algorithms. Conversely, alternative methods ✜rst cluster these measurements and then derive features to characterize these clusters. In this work, we will adopt the latter approach and propose a set of innovative features compared to those described in the specialized literature.  \nEmerging studies utilize deep learning for enhanced detection from sensor data, o✛ering signi✜cant improvements in reliability [21] . Given the absence of automatic labeling tools for 2D laser data, this work explores the potential of deep learning to automate the labeling of such datasets and the use of machine learning approaches to generate e✣cient leg detectors, aiming to enhance e✣-ciency and accuracy in diverse applications [14] .  \nThis work is or","cbCainjztbsent89","https://ap.wps.com/l/cbCainjztbsent89","pdf",3178439,1,15,"English","en",105,"# Introduction\n## Mobile robot people detection background\n## Laser-based approaches and motivation\n## Organization of the work\n# Description of the proposal\n## Simulated testing with CoppeliaSim\n## Real-world validation setup and sensor integration","[{\"question\":\"How does the proposed system combine monocular camera data with 2D LRF data?\",\"answer\":\"A monocular camera is integrated with a 2D LRF mounted on a mobile robot.
