要在Vue3中使用face-api.js进行人脸识别,需要先安装face-api.js库和相关依赖。可以通过以下命令进行安装:
```bash
npm install face-api.js canvas --save
```
接下来,在Vue3中使用face-api.js需要执行以下步骤:
1. 在Vue组件中引入face-api.js库:
```javascript
import * as faceapi from 'face-api.js';
```
2. 在Vue组件中创建一个canvas元素,并将其添加到DOM中:
```javascript
mounted() {
const video = this.$refs.video;
const canvas = this.$refs.canvas;
const context = canvas.getContext('2d');
document.body.append(canvas);
}
```
3. 加载face-api.js模型:
```javascript
async loadModels() {
const MODEL_URL = '/models';
await faceapi.loadSsdMobilenetv1Model(MODEL_URL);
await faceapi.loadFaceLandmarkModel(MODEL_URL);
await faceapi.loadFaceRecognitionModel(MODEL_URL);
await faceapi.nets.tinyFaceDetector.loadFromUri(MODEL_URL);
}
```
4. 进行人脸识别:
```javascript
async detectFace() {
const video = this.$refs.video;
const canvas = this.$refs.canvas;
const context = canvas.getContext('2d');
const { width, height } = video.getBoundingClientRect();
canvas.width = width;
canvas.height = height;
const detections = await faceapi.detectAllFaces(video, new faceapi.TinyFaceDetectorOptions())
.withFaceLandmarks()
.withFaceDescriptors();
context.clearRect(0, 0, canvas.width, canvas.height);
faceapi.draw.drawDetections(canvas, detections);
faceapi.draw.drawFaceLandmarks(canvas, detections);
}
```
以上就是在Vue3中使用face-api.js进行人脸识别的基本步骤。需要注意的是,在调用face-api.js的API时,需要将视频流转换成canvas元素。
