Introducing Check & Adjust feature for the Leica RTC360

当使用Leica Geosystems的3D激光扫描解决方案捕获现实时，测量设备的准确性和可靠性应始终具有最高优先级。这就是为什么我们引入了Leica RTC360 3D激光扫描仪的新检查和调整功能的原因。现在，直接在现场检查RTC360的角度准确性比以往任何时候都更快，更容易。

Leica Geosystems 3D激光扫描仪是制造，组装，调整和校准的，以最高标准。但是，极端的温度变化，恶劣的条件和硬冲击会导致偏差并影响系统的准确性。重要的是，与任何其他光学机械测量设备一样，请定期检查激光扫描仪，以确保测量结果符合制造规格。该定期检查可以由现场中的用户轻松完成，通过短而特定的检查和调整过程。

什么是检查和调整？
检查和调整过程是一种快速，智能和用户友好的解决方案，它允许用户：

1. 检查当前的角度精度RTC360
2. 调整角参数以直接在现场提高RTC360的角度精度

已经可以使用类似的功能Leica Scanstation P30/P40和P50high-end laser scanners, however the Check & Adjust procedure for RTC360 is different by its approach, speed and ease-of-use.

检查和调整RTC360的独特之处是什么？
Check & Adjust is a fully automated, straightforward, one-button, procedure which is easily completed in the field, in less than 6 minutes. It does not require a specific measurement field containing a prescribed configuration of targets, as with other similar solutions on the market today. This makes the feature appealing for users, as the procedure can be carried out directly at the job site in a short period time, without extensive effort or interaction from the user, such as preparing the measurement field, installing the targets and aiming at the targets.

How does Check & Adjust work?
该过程是完全自动化的，仅需要在一个位置进行双重扫描即可计算扫描仪的新角参数和角精度。该功能本身使用基于点正常的视野自校准方法，该方法将对象空间中的两个面孔测量之间的偏差与内部仪器偏差之间的偏差，并根据角度校准参数，根据角度校准参数扫描器。通过使用优化函数最小化两个面中选定的核心点之间的偏差，可以调整角度校准参数。合适的核心点是由最高置信度选择的，这是根据距离，高度角度，平面拟合的残差，点强度，正常偏差和入射角计算的。周围环境在此过程中具有重要作用，因为场景的测量点是算法的唯一输入。因此，必须根据检查和调整用户手册中的检查指南仔细选择扫描的位置。在计算新校准参数之前，系统会自动检查环境的适用性。当环境分类满足需求时，扫描仪的电流和调整后的角度精度将与新的角度校准参数一起计算，可以应用它们以提高扫描仪的角度精度。当用户应用新的角度校准参数时，它们将永久存储在仪器中，并自动应用于所有后续测量。 The angular calibration parameters can be reset to the in-factory calibration values at any time. For each completed Check & Adjust procedure, a PDF report, containing Check & Adjust information, is automatically generated and stored to the USB stick.

为什么检查和调整有益？
The ability to perform Check & Adjust without the need for a special measurement field is a significant advantage for users who frequently transport the scanner to long distance locations. Imagine shipping your scanner by aeroplane from Europe to Australia for an upcoming project - you never really know if the luggage was handled carefully throughout the duration of its journey. The same precaution should be taken with rugged handling at the work site or exposure to extreme environmental conditions. After the exposure of the scanner to such unfavourable conditions, the user can check whether the angular accuracy of RTC360 is still within specification and can improve the angular accuracy, without sending it for inspection and in-factory calibration to a certified Leica Geosystems service centre. Scanning downtime is therefore vastly reduced, significantly boosting productivity on site and at the same time, confidence in the consistency of the scan data accuracy is gained, quickly and effortlessly.

To ensure the best possible scan data quality and to consistently deliver the best results, it is essential to be confident about your measuring equipment no matter what it has been put through. The specified accuracy of the RTC360 can be easily maintained by frequently performing the Check & Adjust procedure, keeping it in optimal working condition.
