Description
Technical field
The present invention relates to a kind of face identification system, specifically is the three-dimensional facial reconstruction system on a kind of rotation platform.Be used for the living things feature recognition field.
Background technology
Mostly common face identification system is to study at 2-dimentional photo or dynamic video sequence, still, discerns based on 2-dimentional photo and to have serious obstacle.The main cause that produces these problems is that people's looks itself are three-dimensional, and photo is the result who three dimensional appearance is carried out plane projection, must lose a part of important information in this process.Adopt the three-dimensional identification and the difference of traditional method maximum just to be that the information of people's face can better show and store, for example topological structure between the depth information of the unique point of people's face and the point or the like.Because three-dimensional face model possesses the characteristics of illumination independence and attitude independence, the fundamental characteristics that can correctly reflect people's face, the influence that the main three-dimensional topology structure of somebody's face is not expressed one's feelings, thereby form metastable face characteristic statement, pass through more fully information like this, can solve misclassification rate and false alarm rate problem in the identifying preferably, therefore the recognition methods based on three-dimensional face model can well solve the problem that exists in this field at present, and this just needs to obtain in advance three-dimensional face model.
Find head and color three dimension scanner (the Head ﹠amp of face that U.S. Cyberware company produces by literature search; Face Color 3D Scanner, model 3030RGB), adopt the Single-chip Controlling stepper motor to rotate pivot arm continuously, laser generator and video camera are housed on pivot arm, utilize laser generator to send low level laser as sweep trace, project the people on the face, video camera obtains the facial image of band sweep trace, be sent to graphics workstation and carry out Flame Image Process, because laser is to the nocuity of human body,, and adopt workstation especially to the nocuity of eye, make system cost very high, this all makes it be restricted in the application aspect the three-dimensional face modeling.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art and defective, the system of the three-dimensional facial reconstruction on a kind of rotation platform is provided.Because it is simple, real-time, initiatively controlled and the people do not had characteristics such as injury that structured light three-dimensional vision has degree of precision, optical strip image information extraction, binocular vision has the advantages that effectively to eliminate system's blind spot simultaneously, and the present invention adopts the rotation platform of coded structured light and binocular camera to obtain the three-dimensional head model fast.When to object (referring to the people here) projection coding grid, can from the image of binocular camera, observe the distortion striped that produces owing to the body form convex-concave.These distortion stripeds can be sent into computing machine by camera, through image processing, finally draw the shape and the volume coordinate of object.
The present invention is achieved by the following technical solutions, comprise: Programmable Logic Controller, step motor drive module, stepper motor, high precision planetary reduction gear box, pivot arm, support, left camera, projector, right camera, platform, platform base, stube cable, computing machine, its annexation is: Programmable Logic Controller is connected by stube cable with motor drive module, and driving pulse is provided; Programmable Logic Controller is connected by stube cable with left camera and right camera simultaneously, and the control camera is clapped and got photograph; A left side camera and right camera are connected with computing machine, and the image that bat is got is sent in the computing machine to be handled; The step motor drive module is connected with motor, the driving pulse that utilizes Programmable Logic Controller to provide, may command stepper motor forward, counter motion; Stepper motor is connected with pivot arm through the high precision planetary reduction gear box, when pivot arm revolution 5 degree, the step motor control pivot arm stops the rotation, Controlled by Programmable Controller left side camera, right camera are clapped and are got people's appearance sheet then, after bat is got and is finished, Programmable Logic Controller continues the driven in rotation arm and rotates, a width of cloth people appearance sheet is taken off in bat, platform center and platform base mechanical connection, and to guarantee that pivot arm can rotate around platform, after rotation platform rotated a circle, the present invention can obtain the picture of the different angles of the whole number of people, was used for three-dimensional modeling and handled; Support is arranged on the pivot arm, adjustable height; Left side camera, right camera and projector are arranged on the support, and distance can be adjusted between camera, and direction also can be adjusted.
The present invention utilizes two CCD cameras to carry out the binocular vision location, and then from parallax, recover distance, realization is to the perception of three-dimensional information, camera and projector are fixed on the support, according to the experiment needs, this support height is adjustable, and position, the camera left and right sides and angle each other also are adjustable; System utilizes the projector projects coded structured light, is convenient to two cameras and extracts corresponding point, carries out three-dimensional reconstruction.Support is erected on the pivot arm of system platform.Pivot arm is by Programmable Logic Controller and step motor drive, stepper motor and high precision planetary reduction gear box come the rotary system platform, Programmable Logic Controller and motor drive module are as stepper motor driver simultaneously, the control pivot arm rotates to an angle (angle can be adjusted as required) at every turn automatically, controls the camera bat simultaneously and gets image.
When the present invention works, the people is sitting on the platform, press start button, the projector projects coded structured light, Programmable Logic Controller work, drive stepping motor, make pivot arm rotate, revolution moves certain angle (the present invention is made as 5 degree), and pivot arm stops operating, and Controlled by Programmable Controller binocular camera is clapped and got the human face photo that has coded structured light, be sent to computing machine and carry out Flame Image Process, after having taken this angle of back, pivot arm is rotated further next angle (5 degree), and the binocular camera is clapped and got the photograph of this angle, being sent to computing machine handles, after pivot arm had changeed 360 degree, system stopped, and prepared sampling the next man's three-dimensional data.For convenience, the present invention can control pivot arm just to be changeed, reverses, and selects when starting.
The present invention has omitted laser generator, utilizes coded structured light and binocular camera can finish the three-dimensional reconstruction work of people's face fast, thereby finishes three-dimensional face identification work, and the present invention also can be used in other image Reconstruction.
