RGBDSLAM 运行出错：terminate called after throwing an instance of 'pcl::IOException'
来源：互联网 发布：创维5t36数据 编辑：程序博客网 时间：2024/06/06 07:50
在学习高博士一起做RGBDSLAM2时，遇到一些问题，现在记录下来：
由于安装了OpenCV 3.2.0，所以在编译的时候，每次需要添加一下cmake路径：
cmake -DCMAKE_PREFIX_PATH=/home/limz/Cmake_module/opencv-3.2.0/build ..
中间的路径是opencv安装的路径;
运行时出错，提示：
point cloud size = 0
terminate called after throwing an instance of 'pcl::IOException'
what(): : [pcl::PCDWriter::writeASCII] Input point cloud has no data!
已放弃 (核心已转储)
出现问题的原因是对空指针进行操作，分析之后发现，没有对图像进行处理，所以没有对点云赋值，点云指针就是空指针。
解决办法，在包含data文件夹路径下运行程序
