ssd跑ssd_pascal_webcam.py时候摄像头只有画面没有识别框

Question

如图所示，这样是什么问题啊，跑的是作者给的例子，

Add extra layers on top of a "base" network (e.g. VGGNet or Inception).

def AddExtraLayers(net, use_batchnorm=True, lr_mult=1):
use_relu = True

# Add additional convolutional layers.
# 19 x 19
from_layer = net.keys()[-1]

# TODO(weiliu89): Construct the name using the last layer to avoid duplication.
# 10 x 10
out_layer = "conv6_1"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 256, 1, 0, 1,
    lr_mult=lr_mult)

from_layer = out_layer
out_layer = "conv6_2"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 512, 3, 1, 2,
    lr_mult=lr_mult)

# 5 x 5
from_layer = out_layer
out_layer = "conv7_1"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 128, 1, 0, 1,
  lr_mult=lr_mult)

from_layer = out_layer
out_layer = "conv7_2"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 256, 3, 1, 2,
  lr_mult=lr_mult)

# 3 x 3
from_layer = out_layer
out_layer = "conv8_1"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 128, 1, 0, 1,
  lr_mult=lr_mult)

from_layer = out_layer
out_layer = "conv8_2"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 256, 3, 0, 1,
  lr_mult=lr_mult)

# 1 x 1
from_layer = out_layer
out_layer = "conv9_1"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 128, 1, 0, 1,
  lr_mult=lr_mult)

from_layer = out_layer
out_layer = "conv9_2"
ConvBNLayer(net, from_layer, out_layer, use_batchnorm, use_relu, 256, 3, 0, 1,
  lr_mult=lr_mult)

return net

Modify the following parameters accordingly

The directory which contains the caffe code.

We assume you are running the script at the CAFFE_ROOT.

caffe_root = os.getcwd()

Set true if you want to start training right after generating all files.

run_soon = True

The device id for webcam

webcam_id = 0

Number of frames to be skipped.

skip_frames = 0

The parameters for the webcam demo

Key parameters used in training

If true, use batch norm for all newly added layers.

Currently only the non batch norm version has been tested.

use_batchnorm = False
num_classes = 21
share_location = True
background_label_id=0
conf_loss_type = P.MultiBoxLoss.SOFTMAX
code_type = P.PriorBox.CENTER_SIZE
