"The attachment \"imu_data.csv\" presents the IMU sensor data. Each row contains a series of values representing different physical quantities measured by the IMU at a specific moment. The data columns from left to right can be generally interpreted as follows. The first two long numerical values represent timestamps. Subsequent three columns represent angular velocities  along the X, Y, Z axes respectively. The last three columns correspond to linear accelerations along the X, Y, Z axes respectively. These IMU data are crucial for tasks like motion estimation, pose tracking, and fusing with other sensor data."

附件"imu_data.csv"包含惯性测量单元（Inertial Measurement Unit，简称IMU）的传感器数据。每一行均包含一系列数值，代表该IMU在特定时刻采集的不同物理量。数据列从左至右的含义可大致说明如下：前两个长数值为时间戳；后续三列分别代表沿X、Y、Z轴的角速度；最后三列分别对应沿X、Y、Z轴的线加速度。此类IMU数据对于运动估计、位姿追踪以及与其他传感器数据融合等任务至关重要。
