OpenCV MediaPipe實(shí)現(xiàn)顏值打分功能
更新時間：2021年12月30日 10:52:37 作者：墻縫里的草
這篇文章主要介紹了通過OpenCV MediaPipe實(shí)現(xiàn)攝像頭實(shí)時檢測顏值打分功能，文中的示例代碼講解詳細(xì)，對我們學(xué)習(xí)Python有一定的幫助，感興趣的可以了解一下
顏值打分
定義可視化圖像函數(shù)
導(dǎo)入三維人臉關(guān)鍵點(diǎn)檢測模型
導(dǎo)入可視化函數(shù)和可視化樣式
將圖像模型輸入，獲取預(yù)測結(jié)果
BGR轉(zhuǎn)RGB
將RGB圖像輸入模型，獲取預(yù)測結(jié)果
預(yù)測人人臉個數(shù)
獲取臉上關(guān)鍵點(diǎn)輪廓的坐標(biāo)，并且將相應(yīng)的坐標(biāo)標(biāo)注出來，在標(biāo)注點(diǎn)之間繪制連線（例如：左眼左眼角的識別點(diǎn)標(biāo)號為33號）
