杂谈
最近发现视力下降严重， 可能跟我的过度用眼有关，于是想着能不能做一个检测用眼疲劳的，灵感来自特斯拉的疲劳检测系统。
效果如下：
实现步骤
- 实现核心算法
- 制作交互界面
- 设计交互逻辑
核心算法
疲劳检测算法讲解：
利用dlib 人脸检测算法来捕获人脸的关键点数（68个关键点）
参考文章：https://blog.csdn.net/monk96/article/details/127751414?spm=1001.2014.3001.5502
获取眼睛和嘴巴的点位置
眼睛疲劳计算公式
利用欧拉距离计算
dist = (||P2 - P6|| + ||P3 - P5||)/ 2 * ||P1 - P4||
对应就是上下距离 与左右的比值， 然后我们设定一个阈值，比如说0.3， 另外设置帧数，如3帧，超过3帧则 检测为闭眼， 在闭眼总数上加1，如果闭眼次数超过设定的阈值（6次），判断为疲劳状态。
哈欠疲劳计算公式
哈欠用于眼睛相同的计算方式来计算打哈欠， 同样设置阈值和帧数， 不同点是在于哈欠是设定为0.8。
tips： 这里需要设置多少时间内没闭眼，这去除计数器，不然长时间的检测，肯定会超过阈值
这里需要拿到眼睛的位置进行计算，引入欧拉距离工具
from scipy.spatial import distance as dist
from collections import OrderedDict
设定点位（固定的）
self.LANDMARKS = OrderedDict([
("mouth", (48, 68)),
("right_eyebrow", (17, 22)),
("left_eyebrow", (22, 27)),
("right_eye", (36, 42)),
("left_eye", (42, 48)),
("nose", (27, 36)),
("jaw", (0, 17))
])
self.EYE_THRESH = 0.3
self.EYE_FRAMES = 3
self.COUNTER_FRAMES = 0
self.TOTAL = 0
self.MOUSE_UP_FRAMES = 5
self.MOUSE_COUNTER_FRAMES = 0
self.MOUSE_RATE = 0.8
(self.lStart, self.lEnd) = self.LANDMARKS['left_eye']
(self.rStart, self.rEnd) = self.LANDMARKS['right_eye']
(self.mStart, self.mEnd) = self.LANDMARKS['mouth']
计算大小 这里计算欧拉距离，然后再把距离进行平均，减少误差
def eye_aspect_ratio(self, eye):
A = dist.euclidean(eye[1], eye[5])
B = dist.euclidean(eye[2], eye[4])
C = dist.euclidean(eye[0], eye[3])
return (A + B) / (2 * C)
def cal_height(self, points):
leftEye = points[self.lStart: self.lEnd]
rightEye = points[self.rStart: self.rEnd]
leftEAR = self.eye_aspect_ratio(leftEye)
rightEAR = self.eye_aspect_ratio(rightEye)
return (leftEAR + rightEAR)/2
设定检测的方法：这里用来每一帧检测图片，并返回信息给到交互界面
def skim_video(self, img, ha, eye, warn):
img_gray = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)
# 人脸数rects
rects = self.detector(img_gray, 0)
close_eye = False
for i in range(len(rects)):
faces = self.predictor(img, rects[i]).parts()
points = np.matrix([[p.x, p.y] for p in faces])
rate = self.cal_height(points) # 闭眼
rate_mouse = self.cal_mouse_height(points) # 哈欠
if rate_mouse > self.MOUSE_RATE and ha:
self.MOUSE_COUNTER_FRAMES += 1
if self.MOUSE_COUNTER_FRAMES >= self.MOUSE_UP_FRAMES:
print('打哈欠')
cv2.putText(img, "haha", (rects[i].left(), rects[i].top() - 60), cv2.FONT_HERSHEY_SIMPLEX, 0.8, (0, 255, 255))
if rate < self.EYE_THRESH and eye:
self.COUNTER_FRAMES += 1
# print('闭眼检测到了，第%s次'%COUNTER_FRAMES)
if self.COUNTER_FRAMES >= 5:
self.TOTAL += 1
self.COUNTER_FRAMES = 0
close_eye = True
else:
self.COUNTER_FRAMES = 0
# for idx, point in enumerate(points):
# pos = (point[0, 0], point[0, 1])
# cv2.circle(img, pos, 2, (0, 0, 255), 1)
# cv2.putText(img, str(idx + 1), pos, cv2.FONT_HERSHEY_SIMPLEX, 0.3, (0, 255, 255))
if self.TOTAL >= 10 and warn:
cv2.rectangle(img, (rects[i].left(), rects[i].top()), (rects[i].right(), rects[i].bottom()), color= (255, 0, 255))
cv2.putText(img, "tired", (rects[i].left(), rects[i].top() - 20), cv2.FONT_HERSHEY_SIMPLEX, 0.8, (0, 0, 255))
print('warning， 您已疲劳，请尽快休息')
return "%s闭眼"%time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()) if close_eye else "", img

检测效果
效果还不错，不过对于不是那么明显的情况可能就不是很好了，如光线不好，人脸不全的情况。
接下来可以放到你笔记本上，让他定时提醒你休息。
