PCL常见运行错误

在运行PFH程序时,遇到下面问题

1. vtkOpenGLTexture (0x252dd00): No scalar values found for texture input!

这篇博客说是以为:
6、运行时出现错误：vtkOpenGLTexture (0000000002540430): No scalar values found for texture input!

原因：创建vtkTextActor时，未调用SetInput()方法；或调用SetInput()方法，参数给的空字符串。这都相当于创建了一个空vtkTextActor，导致该错误发生。

解决方法：创建vtkTextActor时进行初始化，即调用SetInput()方法，且必须给出参数，哪怕是一个空格字符创。

但是并不知道怎么修改,找到了一个替代方法如下

#include <pcl/visualization/pcl_plotter.h>// 直方图的可视化 方法2
.
.
.
程序

.
pcl::visualization::PCLPlotter plotter;
plotter.addFeatureHistogram(*pfh_fe_ptr, 125); //设置的很坐标长度，该值越大，则显示的越细致
plotter.plot();

关于boost的thread模块引发的问题

问题
CMakeFiles/bounding_boxes.dir/bounding_boxes_fea.cpp.o：在函数‘main’中：
bounding_boxes_fea.cpp:(.text.startup+0x12b4)：对‘boost::this_thread::hiden::sleep_until(timespec const&)’未定义的引用

推荐使用解决2
出现这个问题的原因可能是thread没找到:

解决
参考这篇博客：https://stackoverflow.com/questions/43361906/why-cant-i-link-to-boosts-thread-libraries

cmake_minimum_required(VERSION 3.7)
project(untitled)

set(CMAKE_CXX_STANDARD 14)

find_package(Boost REQUIRED COMPONENTS thread system)

add_executable(untitled main.cpp)
target_include_directories(untitled PRIVATE ${Boost_INCLUDE_DIRS})
target_link_libraries(untitled ${Boost_LIBRARIES})

之后，cmake打印的信息如下：
