terminate called after throwing an instance of 'pcl::IOException' what(): : [pcl::PCDWriter::writeASCII] Input point cloud has no data!
时间: 2023-11-18 12:33:12 浏览: 113
This error message indicates that the program is trying to write a point cloud in ASCII format using the PCL library, but the input point cloud has no data. This could be due to an issue with reading the input point cloud or the point cloud being empty.
To solve this issue, you can check the input point cloud file and make sure it contains data. Also, check if the file path and name are correct. If the input point cloud is being generated in the program, make sure it is being populated correctly.
Additionally, you can try using a different format to write the point cloud, such as binary, to see if it resolves the issue.

terminate called after throwing an instance of 'serial::IOException'
根据提供的引用内容,当程序运行时抛出了一个'serial::IOException'的实例,会导致程序终止并显示"terminate called after throwing an instance of 'serial::IOException'"的错误信息。
以下是一个示例代码,演示了如何处理'serial::IOException'异常:
```cpp
try {
// 代码块,可能会抛出'serial::IOException'异常
// ...
} catch (const serial::IOException& e) {
// 捕获'serial::IOException'异常,并进行相应的处理
std::cout << "Caught serial::IOException: " << e.what() << std::endl;
}
```
在上述代码中,我们使用了try-catch语句来捕获'serial::IOException'异常。在try块中,我们可以编写可能会抛出异常的代码。如果在try块中抛出了'serial::IOException'异常,catch块将会捕获该异常,并执行相应的处理逻辑。在catch块中,我们可以使用异常对象的`what()`方法来获取异常的详细信息,并进行输出或其他处理操作。
terminate called after throwing an instance of std::runtime_error what(): set_border
这个错误通常是由于程序中出现了无效的操作或参数导致的。具体来说,这个错误信息表示程序在执行 set_border 函数时出现了异常,可能是因为传递给该函数的参数不符合要求,或者程序内部出现了错误。
要解决这个问题,你可以检查程序中调用 set_border 函数的地方,确保传递给该函数的参数是合法的。你还可以尝试使用调试工具来追踪错误,并查看程序的调用栈,以找出错误的原因。另外,确保你的程序没有内存泄漏或其他常见的错误也是很重要的。
