S10144, will in the pixel value of described candidate region, be defined as target area with the candidate region of the difference value minimum of the pixel value of described the first preset window.
Wherein, in the time getting the coordinate of the first pixel, described the first pixel can be pointed to the direction of the first image from the second image, keep in the constant situation of ordinate, the first pixel is traveled through to any one pixel in described the second image, and can to extract with the region of the value differences value minimum of described preset window from the second image by SAD (SumofAbsoluteDifference) or SSD (SumofSquaredDifference) algorithm matching mode be target area, d point as shown in Figure 3 c.
Certainly, in order to reduce amount of calculation, after getting the coordinate of the first pixel, can be identical with described the first pixel ordinate from described the second image, be more than or equal in the candidate region of abscissa and choose target area.
Certainly, the embodiment of the present invention also can be based on the second image, in the first image, choose with the second image in the region of value differences minimum of the preset window that builds of any one pixel be target area, now, should point to according to the first image the direction of the second image, keep in the constant situation of ordinate, the preset window that the each pixel in the second image is formed travels through the candidate region of described the first image, to obtain target area.
S1015, determine the central pixel point of each described target area;
S1016, the central pixel point of each described the first image is mated with the central pixel point of described target area, obtain the three-dimensional image corresponding with described the first image.
Preferably, in order to improve accuracy of identification, need to extract the human body contour outline in described the first image, on the basis of this human body contour outline, obtain the Pixel Information of each pixel, and from three-dimensional image, obtain with it corresponding pixel range information, because user's human body should be in same plane, thereby have a close pixel range information, therefore before identification, can carry out equal Value Operations to pixel distance corresponding to human body in three-dimensional image, so that the human body in human body contour outline separates with interfere informations such as backgrounds, thereby the high-precision human body that extracts user.
Further, the human body contour outline in three-dimensional image corresponding to described extraction the first image, comprising:
S1021, the three-dimensional image corresponding with the first image set up to the horizontal histogram of range information and longitudinal histogram;
S1022, carry out the straight line extraction process of least square method algorithm based on described horizontal histogram and described longitudinal histogram;
S1023, in the horizontal histogram after straight line extraction process, extract and there is the horizontal straight line of identical ordinate, and longitudinally extracting longitudinal straight line with identical abscissa in histogram.
S1024, obtain the human body contour outline of the three-dimensional image that described the first image is corresponding according to described horizontal straight line and described longitudinal straight line.
U-MAP is horizontal histogram, and abscissa is X-axis, and ordinate is apart from Z. When setting up after U-MAP for 3-D view, human body will be rendered as a horizontal line in U-MAP, in certain continuous X coordinate (human body width), keep same as Z.
In like manner, V-MAP is longitudinal histogram, and abscissa is apart from Z, and ordinate is Y-axis. When setting up after V-MAP for 3-D view, human body will be rendered as an ordinate in V-MAP, in certain continuous Y coordinate (people's height), keep same as Z.
Extract operation by two histogrammic straight lines, verification mutually, identifies human body.
The mode of extracting for human body contour outline has multiple, and the embodiment of the present invention does not repeat them here, exemplary, and the method can be by adopting eight Neighbor searchs to realize.
For matching process, these standard picture display parameters can comprise following information in adaptive storehouse: as shown in table 1
Certainly, shown in table 1, three kinds of image display parameters, only for for example, in actual product, may have how adjustable display parameters, and the operational order of every kind of image display parameters can be modified by the processor of terminal by user.
If user is in continuous moving process, specifically in the time of identification user's the pixel range information of image and angle information, can cross track algorithm according to the pixel change of distance information exchange between the multiple adjacent three-dimensional image getting, for example, JPDA wave filter (JPDAF), many hypothesis are followed the tracks of (MHT) algorithm, dynamic multidigit allocation algorithms etc. mate with the adaptive storehouse of standard picture display parameters, to identify distance and the angle between the residing position of current user and intelligent terminal, and carry out the corresponding operational order of matching result. further can produce corresponding control signal. for example, the angle information that system identification goes out user is 15 degree, range information is in the scope of M2～M3, in the adaptive storehouse of standard picture display parameters, corresponding image display parameters 1,2,3 is that the value of backlight illumination, contrast, brightness of image is respectively A2, B2, C2,, after system identification, carry out according to several different image display parameters value obtaining after coupling the operating function that increases or reduce corresponding several image display parameters.
Further, before step S105, before carrying out the step of corresponding image display parameters regulating command, the described result according to described coupling also comprises:
S1051: described the first image is carried out to recognition of face;
Because recognition of face belongs to comparatively ripe prior art, for example, can pass through skin color segmentation, then carry out the operations such as edge detection process;
S1052: the face identifying is mated with face characteristic storehouse, and the face characteristic information that described face characteristic storehouse prestores different user and described different user be corresponding image display parameters when in different distance and angle respectively;
S1053: if there is face information corresponding and described the first image in described face characteristic storehouse, mate according to user corresponding to the face information of described the first image corresponding image display parameters and corresponding range information and angle information of at least one pixel of determining based on the human body contour outline in described three-dimensional image when in different distance and angle.
If different users has not identical image display parameters regulatory demand in same distance and angle, as the elderly may be because visual impairment, the image display parameters of TV need to be heightened accordingly as backlight illumination, and for the young man in same position, do not need very high backlight illumination to satisfy the demands, because in the time carrying out final image display parameters regulating command, take into account row recognition of face, whether identify is specific user, if there is the face information corresponding to the first image in face characteristic storehouse, that is just according to user corresponding to the face information of described the first image corresponding image display parameters and pixel range information and the angle information based on this three-dimensional image when in different distance and angle, adjust image display parameters. like this, not only realize image display parameters by the judgement of simple distance and angle and regulate, also met the user who has particular demands, can be default according to it or the end value of the adjustment strategy adjustment aim image display parameters that prestores.
Optionally, the step that step S104 mates with the corresponding relation of range information and angle information by the image display parameters in the adaptive storehouse of range information corresponding to described at least one definite pixel and angle information and standard picture display parameters can be specially:
S1041: according to the first range information, in the adaptive storehouse of described standard picture display parameters, determine the first image display parameters value, described the first range information is range information corresponding at least one pixel of determining based on the human body contour outline in described three-dimensional image;
S1042: in the time that the angle information of the definite human body of described three-dimensional image is greater than first threshold, the viewing area of described intelligent terminal is divided into m × n sub-viewing area;
Wherein the angle information of human body can be in the definite human body contour outline of three-dimensional image, the angle information that arbitrary pixel is corresponding, also can be in three-dimensional image, to get multiple pixels, ask the mean value of the angle information that these pixels are corresponding, also human body contour outline that can be corresponding according to three-dimensional image, ask for the barycenter of this human body contour outline, the angle information using the angle information of pixel corresponding barycenter as human body.
S1043: judge the residing angular range of described angle information, obtain the image display parameters value of every sub-viewing area corresponding to the individual sub-viewing area of described m × n according to described angular range from the adaptive storehouse of described image display parameters;
S1044: adjust described the first image display parameters value according to the image display parameters value of described every sub-viewing area.
As shown in table 2, the viewing area of intelligent terminal can be divided into m × n sub-viewing area (block).
| Block 11 | Block 12 | ………… | Block m2 |
| Block 12 | Block 13 | ………… | Block m3 |
| Block 13 | Block 14 | ………… | Block m4 |

When actual realization, master chip SOC end can be divided into mxn block region TV viewing area and independently control. If user is positioned at TV dead ahead, the now skew of angle is relatively little, and just the distance between user and TV changes to some extent, the at this time image display parameters of the image of all block, as brightness and contrast's value can be. If user and TV have certain angle, need so to consider angle and distance composite factor, at this time can show that the brightness and contrast's of the image of zones of different value arranges different image display parameters corresponding to block region according to the adaptive storehouse of image, allow user not feel because the variation of position affects the subjective vision effect of watching, thereby greatly improved user's experience.
