熟悉的测量工作流程在船上Leica ScanStation P系列3D激光扫描仪

Leica ScanStation P系列调查级3D激光扫描仪具有各种板载测量工作流程，通常在使用总站的使用中众所周知。bob apple这些工作流程，快速定向，设置方位角，已知后视，四到六个参数切除，自动切除和遍历，通过已知的控制点提供仪器的设置和方向，或通过计算未知站的坐标来实现已知目标控制的坐标。点。

通过使用指导，在船上测量工作流程扫描P系列, users are able to achieve geo-referenced data directly in the field via the laser scanner onboard user interface. For example, a Resection or Auto Resection option with four or six parameters allows for the calculation of coordinates and orientation of an unknown station, simply by measuring known targets around the setup. Such a procedure is daily business for surveyors when using modern total stations.

切除申请如何工作？

切除的工作流,用户可以选择full six parameters transformation which means three translations along the X,Y and Z axes and three rotations around the same axes. This requires a set of at least three known targets to be acquired. In addition, the four parameters resection allows for the same three translations but for a rotation around the Z axis only. This results in a minimum of two required known targets only, but implies a high accuracy tilt compensation for the levelling of the laser scanner.

As target identification can be easily mixed up and can create a lot of confusion and additional work, the Auto Resection option offers the acquisition of the targets without any target ID input - the geometry of the target configuration around the laser scanner is used to match the correct targets.

阿宝st-processing the data

数据导入后狮子旋风point cloud processing office software, no additional manual registration steps are required in狮子旋风REGISTER。

测量师通常必须将注册到工作坐标系（例如施工网格）注册的数据。该数据是在现场需要通过办公室后处理而延迟的。

扫描P系列onboard surveying applications assist in getting registered, geo-referenced point clouds quickly by a ‘total station like’ procedure.

Specifically for Resection methods mentioned earlier, this means that station coordinates with standard deviations and target coordinates with their residuals can be displayed as values and graphical plots immediately in the field. This helps to get geo-refenced scans directly in the field. Registration errors, which are typically found during office post-processing, can be detected and avoided immediately during the scan acquisition process.

车载测量应用程序的独特之处是什么？

扫描P系列仪器是市场上唯一的激光扫描仪，其中包括这套完整的测量工作流程。此类工作流程是根据P系列激光扫描仪的一些无与伦比和基本特征提供的。Leica Geosystems高端总站中使用的高度准确的双轴补偿器保证了平均扫描数据。bob apple扫描P系列仪器是唯一具有主动目标获取并在板载协调计算的激光扫描仪，即使具有两面目标扫描选项。为此，黑白目标的使用方式与总站的反射棱镜相同。bob apple如果需要，激光坠落允许在标记点上进行精确的仪器设置，而大气和几何校正的输入选项定义了正确距离测量值的比例因子。

How to get access to the onboard surveying applications?

所有测量工作流程都是所有扫描仪P系列激光扫描仪上的预装申请，并且免费，无需额外的许可或费用即可开始。任何知道如何在总站上进行调查工作流程的测量专业人员，直觉knows how to use them on a 3D laser scanner.
