    How to import observation data from Openimu300 into Industrial Explorer

    The direction of the IMU I am currently observing is as followsc0f20d73-a989-464f-bfbc-80d5a84b6a9b-551548b454ff0db5654c63007ba0c65.png

    The z-axis is vertically upward, forming a left-handed coordinate system, and the rotation angle direction of the z-axis is opposite to the x and y axes. The rotation angle in the z-axis is positive clockwise and negative counterclockwise. But the general IMU is a right-hand coordinate system, and the rotation directions of the three coordinate axes are consistent, as shown in adis16488 in the following figure

    And I want to import IMU data into Industrial Explorer and couple GNSS data for future processing. The software is internally defined as a right-hand coordinate system, and the required data is shown in the following figure

    怎样将OpenIMU300的六轴数据导入Inertial Explorer?

    目前我测得的OpenIMU300的轴方向如图1所示83c6a963-5fb9-45e0-95c4-daf503499c2c-image.png 这是一个左手坐标系,且Z轴的角度方向与x、y轴相反。我准备用这个IMU结合GPS信息进行进行紧耦合解算,而一般测绘用的IMU都是右手坐标系,且角度方向应是一致的,如我翻看adis16488的说明书给出的是这样的bebc3ebc-182e-43d5-93c7-4e972e42d00a-image.png
    怎样将Openimu300的数据进行转换,使其可导入到Inertial Explorer 软件中进行解算?该软件中所有关于IMU的定义均是右手坐标系,如下图所示7a2364fc-f32a-4449-88b2-5a239e0e6cdd-image.png
    其软件文档中关于IMU数据的描述如下图所示68ecaaa0-6861-4448-8530-5753ad196c50-image.png
    如果我想将Openimu的观测数据导入Inertial Explorer软件中与GNSS数据进行紧耦合解算,是否需要将原始数据中的zAccel(g)一列的数据乘以-1即可,即可使原来的z轴指向正下方,使其变为右手坐标系,且三个角速度的轴方向均成为逆时针为正的方向(在图1 中,z轴的方向是顺时针为正)df502356-ee43-4791-ad46-9b7cf19c0077-image.png
    第一次使用IMU,如有一些说明不清或用语不当的地方,请见谅
