下载faster r-cnn
git clone --recursive https://github.com/rbgirshick/py-faster-rcnn.git 进入py-faster-rcnn/lib
make
结果如下图:
进入py-faster-rcnn/caffe-fast-rcnn
cp Makefile.config.example MAkefile.config
然后配置Makefile.config文件,可参考我的Makefile.config
执行:make all -j8
结果如下图:
执行:make pycaffe
结果如下图:
下载在VOC2007trainval上预训练的faster r-cnn检测器:
执行:
./data/scripts/fetch_faster_rcnn_models.sh
下载的模型如图所示:
运行演示脚本,
./tools/demo.py
检测结果如下图:(脚本用的是VGG16_faster_rcnn_final.caffemodel)
下载VOCdevkit训练,验证,测试数据集:
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtrainval_06-Nov-2007.tar wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtest_06-Nov-2007.tar wgethttp://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCdevkit_08-Jun-2007.tar
提取压缩文件放到VOCdevkit文件夹下:
tar xvf VOCtrainval_06-Nov-2007.tar
tar xvf VOCtest_06-Nov-2007.tar
tar xvf VOCdevkit_08-Jun-2007.tar
文件夹的结构如下图所示:
为VOCdevkit创建VOCdevkit2007快捷方式,
cd data
ln -s $VOCdevkit VOCdevkit2007
格式如下图所示:
下载在ImageNet上预训练好的模型:
执行:
./data/scripts/fetch_imagenet_models.sh
下载的模型如下图所示:(ResNet.v2.caffemodel是我额外再下载的)
下面开始用voc2007进行训练,执行:
./experiments/scripts/faster_rcnn_end2end.sh [GPU_ID] [NET] [--set ...]
./experiments/scripts/faster_rcnn_end2end.sh 0 ZF pascal_voc(联合训练)
./experiments/scripts/faster_rcnn_alt_opt.sh 0 ZF pascal_voc(分步训练)
下面开始用faster r-cnn来训练自己的数据集(我使用的是faster_rcnn_end2end.sh来执行训练):
首先需要修改网络模型文件:
1./py-faster-rcnn/models/pascal_voc/VGG16/faster_rcnn_end2end/train.prototxt
2./py-faster-rcnn/models/pascal_voc/VGG16/faster_rcnn_end2end/test.prototxt
3.修改/home/amax/guowei/py-faster-rcnn/lib/datasets/pascal_voc.py
修改self._classes为你的类别加背景。
4./home/amax/guowei/py-faster-rcnn/lib/datasets/factory.py修改
for year in ['2007', '2012','2001','2002','2006','5000']:
for split in ['train', 'val', 'trainval', 'test']:
name = 'voc_{}_{}'.format(year, split)
__sets[name] = (lambda split=split, year=year: pascal_voc(split, year))
我的数据集叫:VOC5000,所以把5000加到年份当中。
5/home/amax/guowei/py-faster-rcnn/experiments/scripts/faster_rcnn_end2end.sh修改
case $DATASET in
pascal_voc)
TRAIN_IMDB="voc_5000_trainval"
TEST_IMDB="voc_5000_test"
PT_DIR="pascal_voc"
ITERS=4000
;;
把训练数据集和测试数据集改为你的数据集,迭代次数改为4000。
开始训练,执行下面程序:
/experiments/scripts/faster_rcnn_end2end.sh 0 VGG16 pascal_voc
我的numpy更新到了最新版,如果出现和数据类型相关错误,可参考以下:链接:
http://www.itwendao.com/article/detail/380118.html
实验结果如下图:
利用VGG16,迭代了4000次,取得了78.8%的精度。

make
结果如下图:

下面开始用faster r-cnn来训练自己的数据集(我使用的是faster_rcnn_end2end.sh来执行训练):
首先需要修改网络模型文件:
1./py-faster-rcnn/models/pascal_voc/VGG16/faster_rcnn_end2end/train.prototxt
name: "VGG_ILSVRC_16_layers" layer { name: 'input-data' type: 'Python' top: 'data' top: 'im_info' top: 'gt_boxes' python_param { module: 'roi_data_layer.layer' layer: 'RoIDataLayer' param_str: "'num_classes': 2" #数目为训练类别+1 } } layer { name: 'roi-data' type: 'Python' bottom: 'rpn_rois' bottom: 'gt_boxes' top: 'rois' top: 'labels' top: 'bbox_targets' top: 'bbox_inside_weights' top: 'bbox_outside_weights' python_param { module: 'rpn.proposal_target_layer' layer: 'ProposalTargetLayer' param_str: "'num_classes': 2" } } layer { name: "cls_score" type: "InnerProduct" bottom: "fc7" top: "cls_score" param { lr_mult: 1 } param { lr_mult: 2 } inner_product_param { num_output: 2 weight_filler { type: "gaussian" std: 0.01 } bias_filler { type: "constant" value: 0 } } } layer { name: "bbox_pred" type: "InnerProduct" bottom: "fc7" top: "bbox_pred" param { lr_mult: 1 } param { lr_mult: 2 } inner_product_param { num_output: 8 #(类别数+1)*4 weight_filler { type: "gaussian" std: 0.001 } bias_filler { type: "constant" value: 0 } } }

3.修改/home/amax/guowei/py-faster-rcnn/lib/datasets/pascal_voc.py

修改self._classes为你的类别加背景。
4./home/amax/guowei/py-faster-rcnn/lib/datasets/factory.py修改
for year in ['2007', '2012','2001','2002','2006','5000']:
for split in ['train', 'val', 'trainval', 'test']:
name = 'voc_{}_{}'.format(year, split)
__sets[name] = (lambda split=split, year=year: pascal_voc(split, year))
我的数据集叫:VOC5000,所以把5000加到年份当中。
5/home/amax/guowei/py-faster-rcnn/experiments/scripts/faster_rcnn_end2end.sh修改
