一、背景
我的環境是:Windows10 + python3.7 + anaconda3 + jupyter5.6.0
安裝 Openpose開源庫時,有點費力,在前面一篇文章中講述過,這裏不再重複;前文有模型下載鏈接。
本次涉及的模型有:hand和pose-coco模型
手部:22個關鍵點(21個骨骼點,第22個表示背景),骨骼:coco模型18個特徵點
前文講述了安裝和基本使用方法,本文來將骨骼和手勢
融合在一張圖片中同時檢測並標記。
二、標記
1.標記骨骼特徵
1)剔除不必要點
上一次是基於危險駕駛的探討:
本次我需要手語圖像識別,那麼這裏需要標記的上半身參考點的關鍵信息更多了。
圖中是我訓練時的截圖,可以發現手語所表達的肢體動作均在上半身
,所以我們參考點可忽略(點9,10,12,13) 。
(圖片參考於:中國手語數據集DEVISIGN 數據集以及手語公益網站視頻)
2)特徵
圖像識別,需要以上流程,目前我們在(特徵提取和選擇階段),提取哪些特徵是有價值的特徵呢?
示例:
-
危險駕駛判斷標準:
- 抽菸:可以用雙手到鼻的距離來進行判斷,即點4,7到點0的距離。
- 接電話:可以計算右手到右耳的距離(左手倒左耳的距離)來進行判斷,即點4到點16的距離(點7到點17的距離)。
-
基於普通攝像頭的太極姿勢識別
太極姿勢分爲23式,原作者根據需求提取手臂姿勢、腿部姿勢:
原作者筆記:十五組人體姿態骨骼關鍵點之間的距離作爲特徵,同時選擇
了十五組夾角作爲角度特徵整合到一個數組中去。
爲什麼需要角度作爲輔助判斷參數呢?僅選擇距離判斷因素,當人離攝像頭更遠一些,人就會縮小,距離會變短;人靠近攝像頭,距離會變大,距離因素遠遠不夠。
通過引入角度信息,我們都知道:一條直線不能確定其方向和大小,若是一個向量(有方向有大小的定點線段),那麼這就可以在圖像表示唯一。所以,這裏是通過角度來約束距離。
引入角度有哪些弊端呢?
出自太極手勢識別:
組合特徵:距離和角度,能夠提高複雜關係的擬合能力,同時由於有些角度在某些情況下的值爲零值,比如 2-3-4(整個手臂:手,胳膊肘,肩膀之間的夾角的餘弦值)夾角爲直角的時候餘弦值是零值,當 OpenPose 丟失一個點比如說 4 號位置手的信息沒有檢測出來的時候,返回零值,它的餘弦值就和肩膀之間的夾角的餘弦值)夾角爲直角的時候餘弦值相同了,因此僅僅依據距離信息有時候也會對數據訓練產生一定的誤導作用,所以就按照距離約束角度,角度約束距離的設計思路設計了獨特的太極姿態識別的訓練數據。
通過上述的分析,我們暫且提煉出25組關鍵特徵,如圖:
現在特徵點也規劃好了,上代碼——在其中連線,圈圈畫畫,計算長度角度。
三、實現
1.獲取關鍵點座標
主要還是參考前一文:Openpose駕駛員危險駕駛檢測(抽菸打電話)
前文是單獨提取骨骼特徵點和手勢特徵點,這裏對其進行一個融合,思路是:
-
傳入原圖像,獲取骨骼的coco模型18特徵點
-
手勢特徵點:通過骨骼特徵點
point[4]
和point[7]
標註出兩隻手首的位置,以手首爲中心,取小臂長範圍對圖片進行分割;再別對兩個圖片進行識別。
手勢檢測:
(當然這張圖片裏的dancer戴了手套,會影響手勢部分的檢測。)
此部分代碼:
1. 在裁剪的時候注意左右相反的,我一開始弄錯了,裁剪框老不對
rimg = img_cv2[y1:y2,x1:x2]# 裁剪座標爲[y0:y1, x0:x1]
2. 注意判斷圖像中沒有顯示左手和右手的情況,以及標註框範圍過大時,只裁取到圖像邊緣:def getHandROI(self,imgfile,bonepoints): """hand手部感興趣的區域尋找到雙手圖像 :param 圖像路徑,骨骼關鍵點 :return 左手關鍵點,右手關鍵點座標集合 """ img_cv2 = cv2.imread(imgfile)#原圖像 img_height, img_width, _ = img_cv2.shape rimg = img_cv2.copy()#圖像備份 limg = img_cv2.copy() # 以右手首爲中心,裁剪長度爲小臂長的圖片 if bonepoints[4] and bonepoints[3]:#右手 h = int(self.__distance(bonepoints[4],bonepoints[3]))#小臂長 x_center = bonepoints[4][0] y_center = bonepoints[4][1] x1 = x_center-h y1 = y_center-h x2 = x_center+h y2 = y_center+h print(x1,x2,x_center,y_center,y1,y2) if x1< 0: x1 = 0 if x2>img_width: x2 = img_width if y1< 0: y1 = 0 if y2>img_height: y2 = img_height rimg = img_cv2[y1:y2,x1:x2]# 裁剪座標爲[y0:y1, x0:x1] if bonepoints[7] and bonepoints[6]:#左手 h = int(self.__distance(bonepoints[7],bonepoints[6]))#小臂長 x_center = bonepoints[7][0] y_center = bonepoints[7][1] x1 = x_center-h y1 = y_center-h x2 = x_center+h y2 = y_center+h print(x1,x2,x_center,y_center,y1,y2) if x1< 0: x1 = 0 if x2>img_width: x2 = img_width if y1< 0: y1 = 0 if y2>img_height: y2 = img_height limg = img_cv2[y1:y2,x1:x2]# 裁剪座標爲[y0:y1, x0:x1] plt.figure(figsize=[10, 10]) plt.subplot(1, 2, 1) plt.imshow(cv2.cvtColor(rimg, cv2.COLOR_BGR2RGB)) plt.axis("off") plt.subplot(1, 2, 2) plt.imshow(cv2.cvtColor(limg, cv2.COLOR_BGR2RGB)) plt.axis("off") plt.show() # 分別獲取手部特徵點 rhandpoints = self.getHandKeypoints(rimg) lhandpoints = self.getHandKeypoints(limg) #顯示 pose_model.vis_hand_pose(rimg, rhandpoints) pose_model.vis_hand_pose(limg, lhandpoints) return rhandpoints,lhandpoints
ok,現在你已經get了手勢和骨骼的座標了
2.計算特徵
1)距離
我們圖片是二維的,
def __distance(self,A,B):
"""距離輔助函數
:param 兩個座標A(x1,y1)B(x2,y2)
:return 距離d=AB的距離
"""
if A is None or B is None:
return 0
else:
return math.sqrt((A[0]-B[0])**2+(A[1]-B[1])**2)
在openpose返回的關鍵點座標中,未識別的關鍵點返回None
;因此,我們這裏也要做一個簡單的None判斷,座標都沒有了,還怎麼計算距離呢?🤣
2)角度
我們之前保留的參考點爲三個點:A-B-C式(2-3-4代表右手的手臂角度)
這裏採用餘弦定理:(a,b,c分別是A,B,C的對邊長度)
關於角B的計算公式:
、
其中,我們計算先根據三個點的座標信息,計算各邊長;再計算餘弦的弧度值:
弧度值轉角度值:math.degrees()
,均可(這裏爲了我方便觀察,我暫時轉換了,實際運用時,不用轉換,多一份計算,減慢一分運行速度!)
def __myAngle(self,A,B,C):
"""角度輔助函數
:param 三個座標A(x1,y1)B(x2,y2)C(x3,y3)
:return 角B的餘弦值(轉換爲角度)
"""
if A is None or B is None or C is None:
return 0
else:
a=self.__distance(B,C)
b=self.__distance(A,C)
c=self.__distance(A,B)
if 2*a*c !=0:
return math.degrees(a**2/+c**2-b**2)/(2*a*c)#計算出cos弧度,轉換爲角度
return 0
根據我之前的25個(距離+角度)信息,存放那個在list中,還是比較好理解。
爲了演示,做了部分特徵值參數顯示,大致就是這個意思,這些數據都需要保存收集,爲後面生成模型和識別做準備。
