The popularity of mobile laser scanning systems as a surveying tool is growing among construction contractors, architects, land surveyors, and urban planners. The user-friendliness and rapid capture of precise and complete data on places and objects make them serious competitors for traditional surveying approaches. Considering the low cost and constantly improving availability of Mobile Laser Scanning (MLS), mainly handheld surveying tools, the measurement possibilities seem unlimited. We conducted a comprehensive investigation into the quality and accuracy of a point cloud generated by a recently marketed low-cost mobile surveying system, the MandEye MLS. The purpose of the study is to conduct exhaustive laboratory tests to determine the actual metrological characteristics of the device. The test facility was the surveying laboratory of the University of Agriculture in Kraków. The results of the MLS measurements (dynamic and static) were juxtaposed with a reference base, a geometric system of reference points in the laboratory, and in relation to a reference point cloud from a higher-class laser scanner: Leica ScanStation P40 TLS. The Authors verified the geometry of the point cloud, technical parameters, and data structure, as well as whether it can be used for surveying and mapping objects by assessing the point cloud density, noise and measurement errors, and detectability of objects in the cloud.
移动激光扫描系统作为一种测量工具，在建筑承包商、建筑师、土地测量师和城市规划师中越来越受欢迎。其用户友好性以及能够快速获取关于地点和物体的精确完整数据，使其成为传统测量方法的有力竞争对手。考虑到移动激光扫描（MLS），主要是手持式测量工具的低成本和不断提高的可用性，其测量可能性似乎是无限的。我们对最近上市的低成本移动测量系统MandEye MLS生成的点云质量和精度进行了全面调查。该研究的目的是进行详尽的实验室测试，以确定该设备的实际计量特性。测试设施是克拉科夫农业大学的测量实验室。MLS测量（动态和静态）的结果与一个参考基准进行了并列比较，该参考基准是实验室中的一个几何参考点系统，并且与来自更高等级激光扫描仪Leica ScanStation P40 TLS的参考点云相关。作者通过评估点云密度、噪声和测量误差以及云中物体的可检测性，验证了点云的几何形状、技术参数和数据结构，以及它是否可用于测绘物体。
