关于里程计的使用

作者您好,关于里程计使用部分,我看您的代码里面是将 里程计的 位置测量值 赋值给 GPS因子初值 然后做优化,请问可以这样做的原理可以简单讲一下么?
代码部分:GPSFactor gps_factor(X(correction_count), Point3(odom(0), odom(1), odom(2)), correction_noise);
我理解的 wheel odometry的测量值应该是 线速度 和 角速度,GPS的频率远低于 IMU 和 wheel, 所以应该使用预积分的方式计算imu和wheel 里程计。

没有那个文件或目录

fatal error: thirdparty/kalman/include/kalman/LinearizedMeasurementModelhpp: 没有那个文件或目录
这个问题怎么解决

ROS编译出错

感觉老哥的分享!
但是我在Ubuntu16.04 ROS kinetic环境下编译不成功,出现了gtsam_imu/src/Mestimators.cpp:161:16: error: ‘class gtsam::NonlinearFactorGraph’ has no member named ‘addPrior’ 的报错信息,请问该怎么解决?
还有一个问题想请教,EFK那个功能包跑出来的结果只在终端输出,输出的数据该怎么处理和画图展示?

what is the bag file?

hello i am himhan3455,
and i want to know what is the bag file, i mean , is that a all recorded bag file, like
odom, imu/dat etc combined data ? thanks for reading!
