数据集

手部检测数据集

该项目数据集采用 TV-Hand 和 COCO-Hand (COCO-Hand-Big 部分) 进行制作。

所有数据集的数据格式

size是全图分辨率， (x，y) 是目标物体中心对于全图的归一化坐标，w,h是目标物体边界框对于全图的归一化宽、高。

dw = 1./(size[0])  
dh = 1./(size[1])  
x = (box[0] + box[1])/2.0 - 1  
y = (box[2] + box[3])/2.0 - 1  
w = box[1] - box[0]  
h = box[3] - box[2]  
x = x*dw  
w = w*dw  
y = y*dh  
h = h*dh

为了更好了解标注数据格式，可以通过运行 show_yolo_anno.py 脚本进行制作数据集的格式。注意配置脚本里的path和path_voc_names，path为标注数据集的相关文件路径，path_voc_names为数据集配置文件。

制作自己的训练数据集

  • 如下所示,每一行代表一个物体实例，第一列是标签，后面是归一化的中心坐标(x,y),和归一化的宽(w)和高(h)，且每一列信息空格间隔。归一化公式如上，同时可以通过show_yolo_anno.py进行参数适配后，可视化验证其正确性。
