Opencv_createsamples失败并出现分段错误 [英] Opencv_createsamples fails with segmentation fault

问题描述

我目前正在尝试进行HAAR分类器.我已经制作了一个批注文件，并按照openCV官方教程中的说明进行了所有操作:

I am currently trying to make a HAAR classifier. I have made an annotation file and have done everything as described in the official openCV tutorial: https://docs.opencv.org/3.3.0/dc/d88/tutorial_traincascade.html . However, when I try to create the samples with opencv_createsamples, I get an error. My command:

opencv_createsamples -vec/some_dirs/samples/samples.vec -info/some_dirs/annotations/annotations.dat -w 8 -h 8 -num 100

错误:

已中止(核心已转储)

Aborted (core dumped)

但是，如果我尝试仅做两个样本(不知道为什么精确为2 ...)，尽管我的数据集包含大约300-400张图片，但它会运行并创建.vec文件.

However, if I try to do only two samples (no idea why exactly 2...), it runs and creates the .vec file, although my dataset includes about 300-400 pictures.

annotations.dat

提前感谢您的支持！

推荐答案

已解决！感谢Micka提出解决方案并提出正确建议.注释文件中有错误.对兴趣点的描述之一是 0 0 0 0 ，它是无效的.务必仔细检查文件！

Solved! Thank to Micka for suggesting a solution and being right. There was an error in the annotations file. One of the descriptions of a point of interest was 0 0 0 0 which is invalid. Always check your files carefully!
