这段代码可以进一步改进,例如:
1. 姿态判断的阈值可以根据具体情况进行调整,使判断更加准确。
2. 可以加入更多的关键点信息进行姿态判断,例如肩膀、腰部、脚等关键点。
3. 可以进行多个条件的组合判断,例如判断是否为坐姿时,可以同时考虑膝盖和臀部的位置关系,从而提高判断准确率。
4. 可以将判断结果进行可视化,例如在图像中用不同的颜色标注出不同的姿态,以便更直观地展示判断结果。
下面是一个改进后的代码示例:
```
nose = keypoints(1, :);
lshoulder = keypoints(6, :);
rshoulder = keypoints(5, :);
lelbow = keypoints(7, :);
relbow = keypoints(4, :);
lwrist = keypoints(8, :);
rwrist = keypoints(3, :);
lhip = keypoints(12, :);
rhip = keypoints(9, :);
lknee = keypoints(13, :);
rknee = keypoints(10, :);
lankle = keypoints(14, :);
rankle = keypoints(11, :);
% 判断姿态
if nose(2) < lshoulder(2) && nose(2) < rshoulder(2)
pose = '站姿';
elseif abs(nose(2)-lshoulder(2)) < 30 && abs(nose(2)-rshoulder(2)) < 30 && lknee(2) > lhip(2) && rknee(2) > rhip(2)
pose = '坐姿';
elseif abs(nose(2)-lshoulder(2)) < 30 && abs(nose(2)-rshoulder(2)) < 30 && lknee(2) < lhip(2) && rknee(2) < rhip(2) && abs(lankle(2)-rankle(2)) < 20
pose = '躺姿';
else
pose = '未知姿态';
end
% 可视化结果
figure;
imshow(image);
hold on;
plot(keypoints(:,1), keypoints(:,2), 'r.', 'MarkerSize', 10);
if strcmp(pose, '站姿')
plot([lshoulder(1), rshoulder(1)], [lshoulder(2), rshoulder(2)], 'g-', 'LineWidth', 2);
elseif strcmp(pose, '坐姿')
plot([lhip(1), rhip(1)], [lhip(2), rhip(2)], 'g-', 'LineWidth', 2);
elseif strcmp(pose, '躺姿')
plot([lhip(1), rhip(1)], [lhip(2), rhip(2)], 'g-', 'LineWidth', 2);
plot([lankle(1), rankle(1)], [lankle(2), rankle(2)], 'g-', 'LineWidth', 2);
end
title(pose);
```
