這篇文章主要講解了Django如何調(diào)用百度AI接口實(shí)現(xiàn)人臉注冊(cè)登錄，內(nèi)容清晰明了，對(duì)此有興趣的小伙伴可以學(xué)習(xí)一下，相信大家閱讀完之后會(huì)有幫助。
面部識(shí)別----考勤打卡、注冊(cè)登錄、面部支付等等...感覺(jué)很高大上，又很方便，下面用python中的框架--django完成一個(gè)注冊(cè)登錄的功能，調(diào)用百度AI的接口，面部識(shí)別在網(wǎng)上也有好多教程，可以自己建模，訓(xùn)練模型，但是這都需要大量的數(shù)據(jù)去提高模型的準(zhǔn)確度，我們直接用了百度AI的接口，十分的快捷、高效、準(zhǔn)確，下來(lái)碼一下代碼啦??！
首先需要在百度AI官網(wǎng)注冊(cè)一個(gè)應(yīng)用，免費(fèi)，并提供強(qiáng)大的人臉庫(kù)。
1.注冊(cè)表單
<div class="tab-content">
<div class="tab-content-inner active" data-content="signup">
<!-- <form action="{% url 'regist' %}" method="POST"> -->
<div class="row form-group">
<div class="col-md-12">

<div class="row form-group">
<div class="col-md-12">
<input type="text" class="form-control" id="mobile" placeholder="手機(jī)號(hào)">
</div>
</div>
<div class="row form-group">
<div class="col-md-12">
<input type="password" class="form-control" id="password" placeholder="密碼">
</div>
</div>
<div class="row form-group">
<div class="col-md-12">
<!-- <input type="text" class="form-control" id="mobile_code" placeholder="驗(yàn)證碼">
<input type="button" value=" 獲取驗(yàn)證碼" id="zphone"> -->
</div>
</div>
<div class="row form-group">
<div class="col-md-12">
<label for="password2"><font color='green'>新用戶點(diǎn)擊注冊(cè)會(huì)有面部特征收集哦！</font></label>
</div>
</div>
<div class="row form-group">
<div class="col-md-12">
<input type="submit" class="btn btn-primary" value="注冊(cè)" id="regist">
</div>
</div>
<!-- </form> -->
</div>2.注冊(cè)時(shí)調(diào)用攝像頭，ajax封裝給后端的數(shù)據(jù)

}
if (navigator.mediaDevices.getUserMedia === undefined) {
navigator.mediaDevices.getUserMedia = function (constraints) {
// 首先，如果有g(shù)etUserMedia的話，就獲得它
var getUserMedia = navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;
// 一些瀏覽器根本沒(méi)實(shí)現(xiàn)它 - 那么就返回一個(gè)error到promise的reject來(lái)保持一個(gè)統(tǒng)一的接口
if (!getUserMedia) {
return Promise.reject(new Error('getUserMedia is not implemented in this browser'));
}
// 否則，為老的navigator.getUserMedia方法包裹一個(gè)Promise

4.注冊(cè)接口，按照接口文檔傳入必須的參數(shù)，手機(jī)驗(yàn)證碼功能已在本文中注釋掉，需要時(shí)自行百度。
