Stick Insect Locomotion

The whole-body movements of unrestrained walking and climbing stick insects were measured by marker-based motion-capturing: markers were attached to the body of the insect and tracked by an infrared camera system (Vicon MX10 equipped with 8 T10 cameras). The measured marker trajectories (time-ordered xyz-coordinates) were used to reconstruct the trajectories of various joint locations of the insect, and to calculate the joint angle time courses for all six legs, three thorax segments and the head. The example data provided here is part of a data set comprising several hours of locomotion sequences from three different stick insect species (Carausius morosus, Aretaon asperrimus, Medauroidea extradentata = Cuniculina impigra). Joint angle time courses and footfall patterns have been calculated from the trajectory data. Contains: * Matlab Files from 36 trials, containing original measurements, processed data (e.g., kinematic variables calculated, and metadata). * Sets of overview figures for each trial in one pdf file. * Pairs of videos per trial, showing the side view of a part of the experimental setup, and the whole sequence of recorded marker trajectories. * Motion capture data in bvh format

无束缚状态下步行与攀爬的竹节虫全身运动通过基于标记点的运动捕捉技术进行测量：标记点附着于竹节虫体表，并由红外摄像系统（配备8台T10相机的Vicon MX10）追踪。测得的标记点轨迹（时间序列xyz坐标）被用于重建竹节虫各关节位置的轨迹，并计算其六条腿、三个胸部体节及头部的关节角度时间序列。

本示例数据取自一个包含三种不同竹节虫（Carausius morosus、Aretaon asperrimus、Medauroidea extradentata = Cuniculina impigra）数小时运动序列的数据集。关节角度时间序列与步序模式均由轨迹数据计算得出。
