vbb2voc error

你好，请问vbb2voc中第154行 parse_anno_file取消注释运行，为什么输出的是空文件夹呢。
@w39865008 前面150-153行的输入输出路径确认下，我这边的话seq路径下包括像这样：annotations set00 set01 set02 set03 set04 set05 set06 set07 set08 set09 set10 。你也可以在parse_anno_file函数里面打印一些日志出来看看。
@CasiaFan 你好，我seq路径下和你一样后出现以下错误，我annotations文件下也包含set00 set01 set02 set03 set04 set05 set06 set07 set08 set09 set10文件夹。
wyh@:~/datasets/Dataset_to_VOC_converter-master$ python vbb2voc.py
Parsing annotations of camera: set06
Traceback (most recent call last):
File "vbb2voc.py", line 161, in
main()
File "vbb2voc.py", line 154, in main
parse_anno_file(vbb_inputdir, seq_inputdir, vbb_outputdir, seq_outputdir)
File "vbb2voc.py", line 122, in parse_anno_file
img_size = seq2img(annos, seq_file, seq_outdir)
File "vbb2voc.py", line 55, in seq2img
img_size = (width, height)
UnboundLocalError: local variable 'width' referenced before assignment
我前面路径为：
seq_inputdir = "/home/wyh/datasets/caltech_dataset"
vbb_inputdir = "/home/wyh/datasets/caltech_dataset/annotations"
seq_outputdir = "/home/wyh/datasets/caltech_dataset"
vbb_outputdir = "/home/wyh/datasets/caltech_dataset"
如果改为
seq_inputdir = "/home/wyh/datasets/caltech_dataset"
vbb_inputdir = "/home/wyh/datasets/caltech_dataset/annotations/set00"
seq_outputdir = "/home/wyh/datasets/caltech_dataset"
vbb_outputdir = "/home/wyh/datasets/caltech_dataset"
就会出现空文件夹。
@w39865008 因为脚本是先从vbb_inputdir下面获取各个set的子目录然后再读取里面的文件，所以你改为set00以后是无法读到里面的注释文件的。
而前面出现的错误UnboundLocalError: local variable 'width' referenced before assignment只可能是seq文件没有读到导致的。下面是我用的文件结构：
.

│ ├── set01
│ ├── set02

│ ├── set04

最外层set文件夹中包含的是seq文件，annotations下面的set包含的是vbb文件，所以请再确认下你的输入路径
@CasiaFan 你好，我发现了问题，我的cv2.VideoCapture()不能读取seq文件，我opencv版本是3.1.0，系统是Ubuntu14.04，和这些人一样 mitmul/caltech-pedestrian-dataset-converter#1 请问我应该怎么做呢。
In [17]: seq_file='/home/datasets/caltech/set00/V000.seq'
In [18]: cap = cv2.VideoCapture(seq_file)
In [19]: print cap.isOpened()
False
@w39865008 你的opencv是直接pip install的么，直接安装的opencv好像会有这个问题，可以自己下一个opencv编译安装，我的版本是3.2.0，安装方式是这个
In my case, it is found that the xml file only contains one person even if there are several persons in the image. similar errors occur in your implementation?
@gallonden Sorry, it's a bug and I have fixed it now. BTW, I didn't use this dataset in my project in the end, so maybe some other issues may still exist. Be careful when using this script and any questions are greatly welcome!
@w39865008 你可以用vbb2voc的visualize_bbox打下框看看，这个图我看了下应该是有两个人没错的
@CasiaFan 你好，xml中数据和由vbb直接得到的txt格式的annotation有些不一样，如set00_V013_1511，txt**有7个目标：
1511 400.822523 162.125203 0.836696 39.080048
1511 51.370645 164.734047 46.492069 74.825080

1511 193.408532 154.403275 39.450959 60.578611
xml中只有4个：
400.82252276698284 162.12520252025203
401.659218752758 201.20525052505252

149.3911734469085 221.09626964311946
请问是我提取的数据有问题吗？
@w39865008 我也是opencv无法读取seq文件，参考别的http://www.cnblogs.com/zcftech/p/3641429.html
可以先把seq文件转换为jpg,再使用这个py文件完成vbb文件的转换
had the same issue where opencv-python cant read the .seq files properly, causing empty folders.
i checked the .seq folders for the original dataset and found out there were extra layers of folders, and after removing those i successfully ran the script. if you're having similar problems check your original caltech folders' formatting.
