看检测API
const session = wx.createVKSession({ track: { face: { mode: 1 } // mode: 1 - 使用摄像头；2 - 手动传入图像 }, version: 'v1' }) // 摄像头实时检测模式下，监测到人脸时，updateAnchors 事件会连续触发 （每帧触发一次） session.on('updateAnchors', anchors => { console.log('anchors.points', anchors.points) console.log('anchors.origin', anchors.origin) console.log('anchors.size', anchors.size) console.log('anchors.angle', anchors.angle) }) // 当人脸从相机中离开时，会触发 removeAnchors 事件 session.on('removeAnchors', () => { console.log('removeAnchors') })https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/visionkit/face.html
