Tensorflow对象检测API-错误的对象检测

时间：2018-09-19 08:38:54

标签： tensorflow object-detection

在Google-colab中，我尝试使用带有SSD_mobilenet_v1_pets.config的 Tensorflow对象检测API 来检测汽车，它将humans检测为car和{{1 }}设为car。以下是N/A和size config：

image dimensions

我有1160张各种尺寸的图像（例如：73 x 63、118 x 62、62 x 56、71 x 56、276 x 183、259 x 184、318 x 159、700 x 420、647 x 407、897 x 554）

我上面提到的输出： enter image description here

enter image description here

请澄清，错误检测汽车的原因是由于图像尺寸还是其他原因？

这是我的配置文件

anchor_generator {
  ssd_anchor_generator {
    num_layers: 6
    min_scale: 0.2
    max_scale: 0.95
    aspect_ratios: 1.0
    aspect_ratios: 2.0
    aspect_ratios: 0.5
    aspect_ratios: 3.0
    aspect_ratios: 0.3333
  }
}
image_resizer {
  fixed_shape_resizer {
    height: 300
    width: 300
  }

这是我的pbtxt代码

我还有一个疑问，你们能帮我吗     我试图找出不戴头盔的人。我使用上述相同的模型。 这是我的pbtxt文件

  item {
  id: 1
  name: 'car'
}

我得到了这个输出 enter image description here

请帮助我...

我猜第一位只提到了赛车！！

答案 1 :(得分：0)

正如@Janikan指出的那样，问题出在.pbtxt文件上。由于您使用的是默认的ssd_mobilenet模型，因此在MS-COCO数据集上进行了训练，该数据集实际上有90个类别，汽车的ID为3。由于在标签映射中找不到ID 3，因此输出显示为N /一种。默认标签图中的ID 1是person，这就是为什么其将“ car”显示为所有人的分类的原因。

如果您只想显示汽车。替换pbtxt文件并编辑visualisation_tools以仅过滤所需的class_Id。
