---------------
一、handposeX json 格式示例
cx,cy,fx,fy为相机内参。
label:左右手标签
joint3d:三维手部21关键点
vertex3d:三维手mesh网格点
{author: XIAN,img_name:: ,cx: 112.0,cy: 112.0,fx: 388.9018310596544,fy: 388.71231836584275,hands: [{label: right,joint3d: [[29.402047395706177,-27.920207008719444,587.0807766914368],······],vertex3d: [[10.056010007858276,29.915300235152245,-626.9440693855286],······]}]}

二、脚本运行
cd script/FreiHANDpython read_handposex_json.py
read_handposex_json.py具体实现如下简洁明了
