【问题描述】:
我已经将来自 Clarifai APi 的人脸检测 API 添加到我的项目中,但是,每当我将图像复制到我的项目并单击检测时,它实际上会显示图像但它没有检测到人脸。 见下文 App.js 和 FaceRecognition.js
import React, {Component} from 'react';
import Clarifai from 'clarifai';
import Navigation from './components/Navigation/Navigation';
import Logo from './components/Logo/Logo';
import ImageLinkForm from './components/ImageLinkForm/ImageLinkForm';
import FaceRecognition from './components/FaceRecognition/FaceRecognition';
import Rank from './components/Rank/Rank';
import './App.css';
const app = new Clarifai.App({
apiKey: 'xxxxxxxxxxxx'
});
class App extends Component {
constructor() {
super();
this.state = {
input: '',
imageUrl: '',
box: {}
}
}
calculateFaceLocation =(data) => {
const clarifaiFace = data.outputs[0].data.regions[0].region_info.bounding_box;
const image = document.getElementById('inputimage');
const width = Number(image.width);
const height = Number(image.height);
return {
leftCol: clarifaiFace.left_col * width,
topRow: clarifaiFace.top_row * height,
rightCol: width - (clarifaiFace.right_col * width),
bottomRow: height - (clarifaiFace.bottom_row * height)
}
}
displayFaceBox = (box) => {
console.log(box)
this.setState({box: box});
}
onInputChange = (event) => {
this.setState({input: event.target.value})
}
onButtonSubmit = () => {
this.setState({imageUrl: this.state.input})
app.models.predict(
Clarifai.FACE_DETECT_MODEL,
this.state.input)
.then( response => this.displayFaceBox(this.calculateFaceLocation(response)))
.catch(err => console.log(err));
}
render() {
return (
<div className="App">
<Navigation />
<Logo />
<Rank />
<ImageLinkForm
onInputChange={this.onInputChange}
onButtonSubmit={this.onButtonSubmit} />
<FaceRecognition box={this.state.box} imageUrl={this.state.imageUrl}/>
</div>
);
}
}
export default App;
人脸识别.js
import React from 'react';
import './FaceRecognition.css';
const FaceRecognition = ({imageUrl, box}) => {
return (
<div className='center ma'>
<div className='absolute mt2'>
<img id='inputimage' alt='' src={imageUrl} width='500px' height='auto' />
<div className='bounding-box' style=
{{top: box.topRow, right: box.rightCol, bottom: box.bottomRow, left: box.leftCol}}></div>
</div>
</div>
);
}
export default FaceRecognition;
人脸识别.css
bounding-box {
position: absolute;
box-shadow: 0 0 0 3px #149df2 inset;
display: flex;
flex-wrap: wrap;
justify-content: center;
cursor: pointer;
}
我究竟做错了什么? 我尝试从实际的 Clarifai API 代码中复制粘贴,但没有成功 边界框 css 甚至没有出现在控制台中。 请帮我
