Familiar surveying workflows onboard Leica ScanStation P-Series 3D laser scanners

Leica ScanStation P-Series survey-grade 3D laser scanners boast a variety of onboard surveying workflows which are typically well-known by surveyors from the use of their total stations. These workflows, Quick Orientation, Set Azimuth, Known Backsight, Four or Six Parameters Resection, Auto Resection and Traversing, offer the setup and orientation of the instrument by known control points, or by calculating the coordinates of unknown stations by aiming at known target control points.

By using the guided, onboard surveying workflows on the扫描P系列，用户能够通过激光扫描仪在板上用户界面直接在现场获得地理参考数据。例如，只需通过测量设置周围的已知目标来计算带有四个或六个参数的切除或自动切除选项。使用现代总站时，这种程序是测量师的日常业务。bob apple

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.

Post-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。

特别是针对前面提到的切除方法，这意味着与标准偏差的站坐标和及其残差的目标坐标可以立即显示为值和图形图。这有助于直接在现场进行地理探索的扫描。通常在办公室后处理过程中发现的注册错误，可以在扫描获取过程中立即检测和避免。

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，intuitivelyknows how to use them on a 3D laser scanner.
