In addition, in embodiments of the present invention, in order to improve the accuracy of identification further, when gathering photo or the 3-D view of real human body, acquisition operations can be carried out in the indoor of proper temperature, to avoid the people gathered to wear blocked up clothing, cause the error of coordinate of the articulation point of the backbone both sides gathered very large.In addition, can require that the people gathered not puts a label on and do not wear shoes collection, because cap can cause the coordinate of the joint of head point gathered to there is error, and shoes can cause the coordinate of the foot's articulation point gathered to there is error.By the impact taking these measures can avoid garment feature, guarantee the accuracy of ratio characteristic of the real human body gathered, so improve the ratio characteristic storehouse set up can referential, improve the accuracy of carrying out identification according to this ratio characteristic storehouse.
In embodiments of the present invention, in order to improve the accuracy of identification, and improve the speed of identification, also priority storehouse is set up in the operation of S2-S5 as follows.
S2: obtain test sample book, this test sample book comprises the ratio characteristic of human body respectively under different human body posture;
Select multiple people, for everyone, require that it shows different postures, as stance, crouching appearance, sitting posture or other human posture.Everyone photo under different human body posture or 3-D view is gathered by high-definition camera or kinect.By 3D vision sensor or kinect bone tracer technique from the photo above-mentioned different human body posture or 3-D view, obtain the coordinate of the articulation point of human skeleton structure, and according to the coordinate of these articulation points, calculate the size at each position of human body under different human body posture, then the ratio between the size calculating each position of human body under different human body posture, obtains the ratio characteristic between each position of human body under different human body posture.
Obtain the ratio characteristic of multiple people under different human body posture between each position by the way, everyone mark, the mark of human posture and the ratio characteristic of people under this human posture between each position are associated, and forms test sample book.
S3: the consistent degree of same ratio feature under different human body posture being calculated human body in test sample book by sorting algorithm;
Above-mentioned sorting algorithm can be Decision Tree Algorithm, K-mean (K average) sorting algorithm or NB Algorithm etc.
The numerical value of same ratio feature under different human body posture of same people is obtained, as obtained the numerical value of ratio characteristic under stance, crouching appearance and sitting posture between the long of a people and shoulder breadth from above-mentioned test sample book.The consistent degree of this ratio characteristic under different human body posture is calculated by sorting algorithm.Similarly, everyone consistent degree of same ratio feature under different human body posture is calculated in test sample book.Then the consistent degree of proprietary same ratio feature is averaged computing, obtains the corresponding average homogeneity degree of each ratio characteristic.
S4: the consistent degree corresponding according to each ratio characteristic, determines the priority of each ratio characteristic;
The average homogeneity degree of the ratio characteristic that two positions are corresponding is larger, shows that the steadiness of this ratio characteristic is stronger, and the ratio between the size at these two positions is less by the impact of human posture, and the priority of this ratio characteristic is higher.
The consistent degree corresponding according to each ratio characteristic, be respectively each ratio characteristic and carry out priority assignment, consistent degree is higher, and the priority of imparting is higher.
S5: the priority of the mark of each ratio characteristic and correspondence is formed priority storehouse.
The mark of aforementioned proportion feature can be the dimension name at two positions that ratio characteristic is corresponding, if a mark for the long ratio characteristic corresponding with shoulder breadth can be " long-shoulder breadth ".By the mark of each ratio characteristic and priority corresponding stored corresponding to each ratio characteristic in priority storehouse.
After setting up ratio characteristic storehouse and priority storehouse by the operation of above-mentioned steps S1-S5, as shown in Figure 1A, the operation of 101-104 identifies the identity of human body to be identified as follows.
Step 101: gather video image, determine the image of human body to be identified from video image;
By high-definition camera capture video image, or gather video image by kinect.In embodiments of the present invention, can Real-time Collection video image, the video image gathered before also can directly obtaining high-definition camera or kinect.A human body image is at least comprised in video image.
In the process such as safety monitoring or cracking of cases, first the video image gathered is play by terminal device or server etc., when personnel in charge of the case finds a suspect from the video image play, the image that personnel in charge of the case can click this suspect by input equipments such as mouses chooses this suspect.When terminal device or server detect that in video image, certain human body image is clicked, this human body image is defined as the image of human body to be identified.
Step 102: the coordinate obtaining each articulation point of human body to be identified from the image of human body to be identified;
By 3D vision sensor or kinect bone tracer technique from the image of human body to be identified, obtain the coordinate of the articulation point of the skeleton structure of human body to be identified.
Above-mentioned articulation point can comprise the articulation point of head, neck, left shoulder, left elbow, left hand, right shoulder, right elbow, the right hand, trunk, left hip, left knee, left foot, right hip, right knee and right crus of diaphragm.The coordinate of the articulation point obtained is more, and the ratio characteristic between each position of subsequent calculations human body to be identified is more accurate, also more accurate to the identification of human body to be identified.
In embodiments of the present invention, in order to improve the accuracy of the coordinate of each articulation point of acquisition further, reduce the error of identification, after the coordinate obtaining each articulation point of human body to be identified, also obtain temperature when gathering video image, and from the image of human body to be identified, extract the garment feature of human body to be identified.According to temperature and garment feature, the coordinate to each articulation point corrects.
The above-mentioned operation that the coordinate to each articulation point corrects according to temperature and garment feature, specifically can be realized by following first or the second two kinds of modes, specifically comprise:
First kind of way, when temperature is lower than default temperature threshold value, consider the impact of clothes thickness, by being positioned at the coordinate of the articulation point of backbone both sides near backbone correction for direction first predeterminable range, if the coordinate takeed on left and right two is all to close backbone correction for direction first predeterminable range; When garment feature comprises cap feature, the coordinate of the articulation point of head is corrected the second predeterminable range downwards; When garment feature comprises high-heeled shoes feature, the coordinate of the articulation point of foot is upwards corrected the 3rd predeterminable range.
Above-mentioned default temperature threshold value can be 5 DEG C etc.Above-mentioned first predeterminable range, the second predeterminable range and the 3rd predeterminable range all can rule of thumb set.
The second way, determines the low-temperature range at temperature place, by the coordinate that is positioned at the articulation point of backbone both sides near distance corresponding to backbone correction for direction low-temperature range; Determine the cap height that garment feature comprises, determine that first of cap height place is highly interval, the coordinate of the articulation point of head is corrected the first highly interval corresponding distance downwards.Determine the height heels that garment feature comprises, determine that second of height heels place is highly interval, the coordinate of the articulation point of foot is upwards corrected the second highly interval corresponding distance.
In the second way, different low-temperature ranges can be pre-set, and the distance of need adjustment corresponding to each low-temperature range, and it is interval to pre-set different height, and the distance of the interval corresponding need adjustment of different height.
In conjunction with temperature and clothes details, the coordinate to articulation point corrects, and ensure that the accuracy of human body proportion feature calculation, and then improves the accuracy of identification.
Step 103: according to the coordinate of each articulation point obtained, obtain the ratio characteristic between partes corporis humani position to be identified;
From the coordinate of each articulation point obtained, determine the coordinate of the articulation point at two ends, partes corporis humani position to be identified, according to the coordinate of the articulation point at two ends, partes corporis humani position to be identified, calculate the size of partes corporis humani position to be identified respectively, the ratio between partes corporis humani position is calculated respectively, using each ratio of calculating as the ratio characteristic between partes corporis humani position to be identified according to the size of partes corporis humani position to be identified.
Such as, for human leg, the articulation point at leg two ends is respectively hip joint and ankle-joint, can calculate the length of leg according to the coordinate of hip joint and the coordinate of ankle-joint.For human upper limb, the articulation point of upper limbs two-end-point is distributed as shoulder joint and wrist joint, can calculate the length of upper limbs according to shoulder joint and carpal coordinate.Calculate the ratio between the length of leg and the length of upper limbs, the ratio characteristic between leg and upper limbs can be obtained.
In addition, if also obtain kneed coordinate when obtaining body joint point coordinate, then can calculate thigh length according to hip joint and kneed coordinate, the coordinate according to knee joint and ankle-joint can calculate lower-leg length, obtains leg length to thigh length and lower-leg length summation.Similarly, if also obtain the coordinate of elbow joint, then can calculate the length of upper arm according to the coordinate of shoulder joint and elbow joint, the length of forearm can be calculated according to elbow joint and carpal coordinate, the length of upper arm and the length summation of forearm be obtained to the length of upper limbs.The articulation point when leg and upper limbs exist bending only with two ends so can be avoided to calculate the problem that there is gross error.Also can find out that the coordinate of the articulation point of acquisition is more much more detailed thus, the ratio characteristic between the size at each position of subsequent calculations and each position is more accurate.
Step 104: according to the ratio characteristic between each position and the ratio characteristic storehouse that prestores, identify the identity of human body to be identified.
