Repetitive trajectory testing in Tschamut 2014

In summer 2014, 6 rock blocks between 20 and 80kg have been thrown in total 111 times down a slope at the Swiss Oberalppass close to the village Tschamut. The slope was mainly covered by grass and its lower part was flat and large enough to provide natural runouts of the single trajectories.
An extensive measurement program has been set up to measure the block trajectories: With surveyor's instruments the slope and the six used rock blocks were scanned and the start and end positions of each test were recorded. During the single events two cameras filmed the trajectories. A special sensor device located within the blocks recorded the acting accelerations and rotational speeds over time. Further, the device emitted a Wifi signal that got detected from eight receivers around the slope. Based on this signal the block position has been recorded over time.
The dataset contains all data that were gathered through above field campaign.

2014年夏季，在瑞士靠近查穆特村（Tschamut）的奥伯拉普山口（Oberalppass）区域，研究人员共开展111次岩块滚落试验，将6块重量介于20~80千克的岩块沿斜坡滚落。该斜坡主体被草本植被覆盖，下部地势平缓开阔，足以为单次滚落轨迹提供天然停积区域。
为采集岩块滚落轨迹数据，研究团队搭建了一套系统的测量方案：采用测量仪器对斜坡及6块受试岩块进行扫描，并记录每次试验的起始与终止位置；单次试验过程中，两台摄像机同步拍摄岩块的滚落轨迹；内置在岩块内部的专用传感装置可实时记录岩块所受加速度与转速随时间的变化；此外，该装置会发射WiFi信号，斜坡周边布设的8台接收器可捕获该信号，借此实时记录岩块的位置随时间的演化过程。
本数据集包含上述野外试验采集的全部数据。
