More than various application according to image color (Hue) information of the utility model acquisition as criterion, after the factor of the shadow that eliminating may be judged by accident,, can improve the accuracy of detecting again by the comparison of matching degree between image.
Fig. 2 is the chrominance space schematic diagram of color-saturation-brightness that the utility model utilized.
One of the coordinate form in Fig. 2 display color-saturation-YC space, this routine color-saturation-YC space is shown as the spatial coordinate of a circular cone pattern, wherein vertically expression by the darkest black to the brightest in vain, express with brightness (Intensity) i.And that its The midsagittal plane circle coordinates are presented at is graphic right-hand, and radius of circle is represented saturation (Saturation) s, and the center of circle is that saturation is minimum 0, then represents maximum saturation near the part of circumference; Circumference is spent to 360 degree by 0 and is then represented color (Hue) h, color in regular turn by red (Red), yellow (Yellow), green (Green), dark green (Cyan), blue (Blue) to fuchsin (Magenta).
Below only enumerate the expression pattern in a kind of color-saturation-YC space, actual enforcement is not restriction with these two kinds then.
The original color of expressing that the image information that the utility model utilized need be captured by the R-G-B chrominance space, be converted on the chrominance space of color-saturation-brightness, and the variable of eliminating saturation and brightness, be that variable carries out the image difference identification only with color (Hue).Color-values herein can angle represent, spends to 360 degree by 0, and every kind of angle is represented a kind of color,
Conversion regime is as follows, and this example only is one of embodiment, but actual enforcement is not restricted to this.Such as, brightness is the mean value of red, green, blue with i=1/3 (R+G+B) expression; Saturation represents that with s=1-(3/ (R+G+B)) * a wherein a is the minimum value in the red, green, blue; Color then can be expressed by h=cos^ (1) ((0.5* ((R-G)+(R-B)))/((R-G) ^2+ (R-B) * (G-B)) ^ (0.5)).
Other has the following row mathematical expression of known technology (can be with reference to United States Patent (USP) the 6th, 665, No. 439) to carry out chrominance space, shown in equation (1):
imax=max(r,g,b)
imin=min(r,g,b)
Brightness i=(imax+imin)/2
Work as imax=imin
Saturation s=0
As i<=(max_value)/2
Saturation s=(imax-imin)/(imax+imin) * max_value
As i>(max_value)/2
Saturation s=(imax-imin)/(max_value-imax-imin) * max_value
rl=(imax-r)/(imax-imin)
gl=(imax-g)/(imax-imin)
bl=(imax-b)/(imax-imin)
Work as imax=imin, then color h there is no definition
Work as r=imax, then color h=((bl-gl) π/3
Work as g=imax, then color h=((2+rl-bl) π/3
Work as b=imax, then color h=((4+gl-rl) π/3
R wherein, g, b are the original color value of each picture element, imax is r, g, the maximum of b, imin is r, g, the minimum value of b comprises brightness i and saturation s, scope all is by 0 to maximum, if with 8 recording mode, maximum is 255, just the variable max_value in the equation (1).Color is then represented with angle, by 0 to 2 π.
Utilize aforesaid equation (1), with each picture element (r (and x, y), g (x, y), b (x, y)) be converted to respectively h (x, y), s (x, y) with i (x, y).
The utility model utilizes the embodiment of the device of image color information and executing image comparison can be with reference to figure 3.
As shown in the figure, the preferred embodiment of this device 300 comprises the taking unit 301 that can capture continuous pictures at least, wherein has optical lens 31, the driver element 32 that controls lens is taken, analog picture through camera lens 31 acquisitions will be converted to digital signal by an analog digital converting unit 33, by imageing sensor (as CCD, CMOS) 34 each picture element exposure value of record.Wherein having more a control unit 35, mainly is the control signal that receives from processing unit 307, and the running of each circuit in the control taking unit 301 comprises the adjustment of 31 rotations of control drive unit 32 execution camera lenses, focal length, picture distance.
The scratch-pad memory 305 that one electric connection taking unit 301 is arranged, in order to temporary image information through 34 sensings of imageing sensor, scratch-pad memory 305 is generally flash memory (flash) or the dynamic random memory (RAM) that is arranged at system front end, maybe can use the middle particular block of hard disk.
Handling core in the system is processing unit 307, and it electrically links each circuit, as shown in the figure, comprises link control unit 35, scratch-pad memory 305, storage element 309, communication unit 313 and image processing module 315.The whole device that utilizes the comparison of image color information and executing image is by communication unit 313, and is online with wired or wireless communication means and Long-distance Control machine room 30, and control machine room 30 is by control signal, by processing unit 307 control taking units 301.
Processing unit 307 is in order to carrying out an image processing program, and by capturing a reference picture and successive image in the consecutive image, carries out image chroma space conversion, matching operation and judgement by image processing module 315.
Wherein, the correlation degree of image before and after can drawing by specific matching operation between reference picture and successive image (correlation operation), can with the basis of this matching degree, not give unnecessary details again with reference to various known technologies at this as the change of judgement image.
Storage element 309 is used to store the successive image of acquisition in reference picture and a period of time, can connect or a built-in database 311.According to embodiment, database 311 records the information of image in each, object especially, writes down the image information of a plurality of object type, comprises color (Hue) feature that captures through chrominance space conversion back in the image object.
Wherein have more software program or the hardware circuit of carrying out the utility model image transitions, comparison in the image processing module 315, electrically connect processing unit 307, in order to carry out the color space conversion of reference picture and successive image, by the chrominance space conversion program, each frame in the image is converted to the chrominance space of color-saturation-brightness from the residing chrominance space of script, capture the wherein color character of specific one or more object again, with the matching operation between image before and after carrying out, and the result is back to processing unit 307.Can be with reference to embodiment shown in Figure 4.
