所以我使用
facedector中构建的机器人来检测和确定位图中面部的位置.现在它起作用并告诉我：信心,眼睛距离和中点,但每当我试图获得姿势时,无论我尝试使用什么图像,它总是返回0.
poseString = "Pose: (" + getFace.pose(FaceDetector.Face.EULER_X) + ","
+ getFace.pose(FaceDetector.Face.EULER_Y) + ","
+ getFace.pose(FaceDetector.Face.EULER_Z) + ")";
这是我使用的代码：
arrayFaces = new FaceDetector(picWidth,picHeight,NUM_FACES);
arrayFaces.findFaces(sourceImage,getAllFaces);
for (int i = 0; i < getAllFaces.length; i++) {
getFace = getAllFaces[i];
try {
PointF eyesMP = new PointF();
getFace.getMidPoint(eyesMP);
poseString = "Pose: ("+ getFace.pose(FaceDetector.Face.EULER_X) + ","
+ getFace.pose(FaceDetector.Face.EULER_Z) + ")";
EULER_X = getFace.EULER_X;
EULER_Y = getFace.EULER_Y;
EULER_Z = getFace.EULER_Z;
eyesDistance[i] = getFace.eyesDistance();
eyesMidPts[i] = eyesMP;
if (DEBUG) {
currentx = eyesMidPts[i].x;
currenty = eyesMidPts[i].y;
betweeneyes = getFace.eyesDistance();
Log.d("currentx",currentx + "");
Log.d("currenty",currenty + "");
Log.d("betweeneyes",betweeneyes + "");
Log.d("EULER","EULER_X: " + EULER_X + "EULER_Y: " + EULER_Y + "EULER_Z: " + EULER_Z);
Log.i("Face",i + " " + getFace.confidence() + " "
+ getFace.eyesDistance() + " " + "Pose: ("
+ getFace.pose(FaceDetector.Face.EULER_X) + ","
+ getFace.pose(FaceDetector.Face.EULER_Y) + ","
+ getFace.pose(FaceDetector.Face.EULER_Z) + ")"
+ "Eyes Midpoint: (" + eyesMidPts[i].x + ","
+ eyesMidPts[i].y + ")");
}
} catch (Exception e) {
if (DEBUG)
Log.e("Face",i + " is null");
}
}
解决方法
一个粗略的谷歌搜索显示大约10个不同的帖子 – 有些甚至
on StackOverflow – 有相同问题的人.你找到了吗？看起来它可能是一个bug.我建议你把它报告给
android bug tracker.
编辑：你一定要提交一个bug.看看人脸检测源代码：this source file显示Android永远不会将这些设置为0以外的任何内容.
在此更改之前,Android还有其他CV选项.查看OpenCV for Android,该团队现已正式支持.
