修改：
nav2d_karto/OpenKarto/source/OpenKarto/Sensor.h文件
找到
m_NumberOfRangeReadings = static_cast<kt_int32u>(math::Round((GetMaximumAngle() - GetMinimumAngle()) / GetAngularResolution()) + 1);
修改为：
m_NumberOfRangeReadings = static_cast<kt_int32u>(math::Round((GetMaximumAngle() - GetMinimumAngle()) / GetAngularResolution()));

但是 apt-get 下载的文件不能直接修改，需要下载源码再重新编译。
需要下载open-karto 和 slam-karto源码 (我的权限不够不能贴链接，大家自己找一下)
可以在ROS工作包caktkin_ws中的源码文件夹src中下载git源码
下载完之后再修改 Karto.h 头文件中的上述代码，即
找到
m_NumberOfRangeReadings = static_cast<kt_int32u>(math::Round((GetMaximumAngle() - GetMinimumAngle()) / GetAngularResolution()) + 1);
修改为：
m_NumberOfRangeReadings = static_cast<kt_int32u>(math::Round((GetMaximumAngle() - GetMinimumAngle()) / GetAngularResolution()));
再重新编译
cd ~/catkin_ws
catkin_make
就可以啦～
