Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, based on the embodiments of the invention, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the invention.
In the description of the present invention, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1, this embodiment provides a photographing method based on an intelligent terminal, including:
1) And acquiring a user image and prompting the user to perform head lifting, lowering, left turning and right turning operations.
2) And (2) recognizing the face region in the image obtained in the step (1), measuring the maximum length and the maximum data of the face region in the whole process of lifting, lowering, turning left and turning right of the head of the user, and respectively extracting the maximum data and the maximum data to serve as the standard values of the length and the width of the face region.
The face area is presented in a plane shape when photographing, the maximum length of the face presented in the plane shape can be changed when the face is lifted or lowered, namely, when the face is right opposite to the camera, the head is not lifted or lowered, the projection length of the face on the horizontal plane is longest, and when the head is lifted or lowered, the projection length of the face on the horizontal plane can be shortened. Similarly, when the face is right against the camera, the head is completely ended when the head does not rotate left and right, the projection width of the face on the horizontal plane is widest, and when the head rotates left or right, the projection length of the face on the horizontal plane is narrowed. The maximum width of the face region can preferably detect the projection width of the two ear ends of the face on the horizontal plane. The invention recognizes whether the head gesture of the user is correct in this way.
3) Setting a length threshold and a width threshold of the face region when photographing according to standard values of the length and the width of the face region; wherein, the length threshold value range is 92-96% of the length standard value; the width threshold value range is 92-96% of the width standard value; the threshold is 92-96% of the standard value, and because the head posture of the user is difficult to be adjusted in percentage, certain deviation is allowed in the normal shooting process, and the shooting efficiency can be greatly improved under the condition of ensuring the shooting quality.
4) Prompting a user to take a picture, acquiring a user image, identifying a face area in the image, and measuring the maximum length and the maximum data of the face area;
5) When the maximum length and the maximum width of the detected face area are larger than the set length and width threshold values, prompting a user to keep stable posture and taking a picture;
6) When the maximum length of the detected face area is smaller than the set length threshold, prompting the user to lift or lower the head, wherein the specific steps are as follows:
when the maximum length of the face area is measured to be smaller than the set length threshold, the head of the user is firstly prompted to rotate upwards or downwards, namely, the user is firstly prompted to rotate upwards or downwards at one side, and the change of the maximum length of the face area in the rotation process is detected.
When the head of the user rotates from the inclined side to the right side, the maximum data of the face area of the user gradually becomes larger, and the maximum data of the face area is maximum when the end is completely closed; as the user's head continues to turn to an increasing degree of inclination toward the incline side, the maximum length of the user's face area will become progressively smaller.
When the maximum length of the face area gradually becomes larger, prompting the head of the user to continuously rotate towards the side direction until the maximum length of the face area is measured to be larger than the set length threshold;
when the maximum length of the face area is gradually reduced, the head of the user is prompted to rotate in the opposite direction until the maximum length of the face area is measured to be larger than the set length threshold. The maximum length of the face area measured currently is larger than the length threshold, and the user is prompted not to lift or lower the head, namely, the head is kept from moving up and down.
When the maximum width of the detected face area is smaller than the set width threshold, prompting the user to turn left or right the head, wherein the specific steps are as follows:
when the maximum width of the face area is detected to be smaller than the set width threshold, the head of the user is firstly prompted to rotate leftwards or rightwards, namely, the user is firstly prompted to rotate leftwards or rightwards, and the change of the maximum width of the face area in the rotation process is detected.
Similarly, when the head of the user rotates from the inclined side to the right side, the maximum data of the face area of the user gradually becomes larger, and the maximum data of the face area is maximum when the end is completely closed; as the user's head continues to turn at an increasing inclination towards the sloping side, the maximum data of the user's face area will become progressively smaller.
When the maximum width of the face area gradually becomes larger, prompting the user to continuously rotate the head towards the side direction until the maximum width of the face area is measured to be larger than a set width threshold value;
when the maximum width of the face area is gradually reduced, the head of the user is prompted to rotate in the opposite direction until the maximum width of the face area is measured to be larger than the set width threshold. When the maximum width of the detected face area is larger than the width threshold value, prompting the user not to turn the head left and right.
In the process of lifting, lowering, left turning and right turning of the head according to the prompt, the user compares the maximum length and the maximum width of the currently measured face area with the set length and width threshold values in real time and feeds back the comparison result in real time, so that the user can conveniently and accurately adjust the head gesture of the user according to the real-time feedback result.
Through the mode, the prompt can be given to the user, and the user can turn the head to be righted according to the prompt.
When the maximum length and the maximum width of the detected face area are larger than the set length and width threshold values, prompting the user to keep the gesture and taking a picture.
Wherein, the prompting mode selects any one or more of voice prompting and text prompting. As a further improvement, the system can also carry out image dynamic prompt, namely prompt the user in a dynamic video image mode, and simultaneously can also carry out prompt in a mode of combining words, images and voices.
