Abstract
The invention relates to a control method for three-dimensional model building based on two-dimensional photos, which is characterized in comprising following steps: 1) creating a universal three-dimensional model for a human face by a computer; 2) building a three-dimensional model for the human face as the controlling target on the model in step 1) to control the human face target through single face photo; 3) generating face photos and face templates to a plurality of postures of the controlling target from the three-dimensional model of the faces; 4) comparing and identifying the original photo and the photos or templates. The invention has the advantages that: 1) In a control system, the ability of a machine to identify human faces is reinforced due to a plurality of postures of the face template; 2) with reduction of the request of the face postures when the machine identifys human faces, that is the face postures and the postures on the photos are not both stressed on exactly the same, the misdeclaration rate of the identification is reduced.
Description
Technical field
The present invention relates to the correlative technology field of computer face identification, particularly a kind of comparison method of the three-dimensional modeling based on two-dimension picture.
Background technology
In the system of deploying to ensure effective monitoring and control of illegal activities,, during people's face of going to occur in the identification video,, must cause based on people's face comparison recognition effect of the photo of this object bad because the attitude of people's face is inconsistent in the video according to the photo of the object of deploying to ensure effective monitoring and control of illegal activities.In addition, in the recognition of face based on template matches, people's face picture of a two dimension often can only generate a face template.
Summary of the invention
The objective of the invention is for a kind of comparison method of the three-dimensional modeling based on two-dimension picture is provided, solved in the system of deploying to ensure effective monitoring and control of illegal activities, photo according to the object of deploying to ensure effective monitoring and control of illegal activities, during people's face of going to occur in the identification video, because the attitude of people's face is inconsistent in the video, must cause the bad problem of people's face comparison recognition effect, and in the recognition of face based on template matches, people's face picture of a two dimension often can only generate the problem of a face template based on the photo of this object.
For achieving the above object, the present invention has adopted following technical scheme:
The invention discloses a kind of comparison method of the three-dimensional modeling based on two-dimension picture, it is characterized in that: may further comprise the steps: the three-dimensional model of 1) setting up general people's face with computing machine; 2) single photo by the object person face of deploying to ensure effective monitoring and control of illegal activities is set up the three-dimensional model of the object person face of deploying to ensure effective monitoring and control of illegal activities on the three-dimensional model of the described general people's face of step 1); 3) generate the people's face picture or the face template of the object of deploying to ensure effective monitoring and control of illegal activities of various attitudes by the three-dimensional model of the object person face of deploying to ensure effective monitoring and control of illegal activities; 4) will deploy to ensure effective monitoring and control of illegal activities people's face picture of the object of deploying to ensure effective monitoring and control of illegal activities of the original photo of object and generation or face template jointly as the identification of comparing of comparison source.
Because adopted above scheme, the beneficial effect that the present invention is possessed is: 1) in the system of deploying to ensure effective monitoring and control of illegal activities,, strengthened the ability of machine recognition people's face because the face template of multiple attitude has been arranged; When 2) having reduced machine recognition people face, to the requirement of human face posture, the attitude that promptly de-emphasizes the attitude of people's face and photo is just the same, thereby has reduced the rate of false alarm of identification.
Embodiment
Below in conjunction with embodiment the present invention is further described.
A kind of comparison method of the three-dimensional modeling based on two-dimension picture is characterized in that: may further comprise the steps: the three-dimensional model of 1) setting up general people's face with computing machine; 2) single photo by the object person face of deploying to ensure effective monitoring and control of illegal activities is set up the three-dimensional model of the object person face of deploying to ensure effective monitoring and control of illegal activities on the three-dimensional model of the described general people's face of step 1); 3) generate the people's face picture or the face template of the object of deploying to ensure effective monitoring and control of illegal activities of various attitudes by the three-dimensional model of the object person face of deploying to ensure effective monitoring and control of illegal activities; 4) will deploy to ensure effective monitoring and control of illegal activities people's face picture of the object of deploying to ensure effective monitoring and control of illegal activities of the original photo of object and generation or face template jointly as the identification of comparing of comparison source, effectively improve the ability of machine recognition people's face.
Claims (1)
1. comparison method based on the three-dimensional modeling of two-dimension picture is characterized in that: may further comprise the steps:
