Referring to the first schematic diagram of the embodiment of Fig. 2, Fig. 3 and Fig. 4 description object tracking image treatment system to the 3rd schematic diagram, and referring to the explanation of Fig. 1.First, tracing object selected cell 40 determines to treat tracing object 30 in the first wide field image 11 of Fig. 2 and the first Narrow Field Of Vision image 21 of Fig. 3, and by image-zooming and deformation unit 80 determine the wide field image 11 of use first or the first Narrow Field Of Vision image 21 wherein one as the first image output 41, and to treat that the area size of tracing object 30 at this first image output 41 is as with reference to region 82, illustrates using the first Narrow Field Of Vision image 21 as the first image output 41 in the present embodiment.
Then by tracking feature acquisition unit 50 in the first wide field image 11 of Fig. 2 and Fig. 3 the first Narrow Field Of Vision image 21 treat in tracing object 30, capture multiple first image features 32 treating tracing object 30.And multiple first image features 32 that object tracing unit 51 provides according to tracking feature acquisition unit 50, described in finding in the second wide field image 12,13 and 14 of Fig. 2 and the second Narrow Field Of Vision image 22,23,24 of Fig. 3, treat tracing object 30.For example, multiple first image features 32 that object tracing unit 51 can provide according to tracking feature acquisition unit 50, find out wide area of visual field size 71, that is treat the region at tracing object 30 place in the multiple second wide field image 12,13,14; And, in multiple Narrow Field Of Vision image 22,23,24, find out Narrow Field Of Vision area size 72, that is treat the region at tracing object 30 place.
Then, feature extraction unit 70 is in finding multiple image feature in the multiple second wide field image 12,13,14 and multiple Narrow Field Of Vision image 22,23,24, the image feature that jointly comprises of image that this multiple image feature is the first camera lens module 10 and the input of the second camera lens module 20, is used to comparison and goes out corresponding region 73,74 in the wide field image of the first camera lens module 10 and the Narrow Field Of Vision image of the second camera lens module 20.Its object is to judge that the second Narrow Field Of Vision image 22,23,24 is in the second wide field image 12,13,14 corresponding region each other.
Then, compared, to determine the size relatively reference zone 82 of whichever with wide area of visual field size 71 and Narrow Field Of Vision area size 72 by image-zooming and deformation unit 80 pairs of reference zones 82.In enforcement, image-zooming and deformation unit 80 can compare by the area size of the area size in this little region and reference zone 82.Such as, the ratio between the area size in wide area of visual field size 71 and Narrow Field Of Vision area size 72 and reference zone 82 closest to one, then can be regarded as comparatively close to reference zone 82.Such as, treat that the area size of tracing object 30 in Narrow Field Of Vision area size 72 is 1.2 times of reference zone 82, and treat that the area size of tracing object 30 in wide area of visual field size 71 is 0.95 times of reference zone 82.0.95 to 1.2 closer to 1, so image-zooming and deformation unit 80 then can carry out follow-up image using the second wide field image 12 as a main image combine process.
Or image-zooming and deformation unit 80 can compare by the image feature quantity of the image feature quantity in this little region and reference zone 82.Such as, when the first camera lens module 10 and the second camera lens module 20 are when the object be taken is close, the part of object in second Narrow Field Of Vision image 22 likely can appearance and not being photographed, namely represent that some image feature does not appear in image, then image-zooming and deformation unit 80 are not suitable for selecting this kind of image to do subsequent treatment.Therefore, image-zooming and deformation unit 80 can select image feature quantity to do subsequent treatment closest to the image of reference zone 82.
Foregoing illustrates with the area size of imagery zone or image feature quantity, but the present invention is therefore not restricted; In addition, the use of area size or image feature quantity also can mix enforcement.
When image-zooming and deformation unit 80 judge until the Narrow Field Of Vision area size 72 of tracing object 30 in the second Narrow Field Of Vision image 22 relatively reference zone 82 time, image-zooming and deformation unit 80 first carry out convergent-divergent and deformation process to the second Narrow Field Of Vision image 22 according to Narrow Field Of Vision area size 72 and a relative scale of reference zone 82, and carry out convergent-divergent and deformation process to a wide corresponding region, the visual field 73 of second wide field image 12 this Narrow Field Of Vision area size 72 corresponding.Otherwise, if until the wide area of visual field size 71 of tracing object 30 in the second wide field image 12 relatively reference zone 82 time, image-zooming and the wide area of visual field size of deformation unit 80 bases 71 carry out convergent-divergent and deformation process with a relative scale of reference zone 82 to the second wide field image 12, and carry out convergent-divergent and deformation process to a Narrow Field Of Vision corresponding region 74 of the second Narrow Field Of Vision image 22 this wide area of visual field size 71 corresponding.
Finally, merged to produce one second image output 25 with corresponding region, the wide visual field 73 to the second Narrow Field Of Vision image 22 after convergent-divergent and/or deformation process by visual fusion unit 90, this second image output 25 can present treats that the size of tracing object 30 does not change haply, but treats the effect that the scenery beyond tracing object 30 has convergent-divergent to change.
Further instruction, Fig. 2 and Fig. 3 emulates camera head 60 gradually near the situation treating tracing object 30, the first original Narrow Field Of Vision image 21, second Narrow Field Of Vision image 22,23 and 24, and the size treating tracing object 30 in the wide field image 12,13 and 14 of the first wide field image 11, second becomes large gradually, and the object having Narrow Field Of Vision image all in wide field image.In 4A figure, first image output 41 produces from the first Narrow Field Of Vision image 21, 4B figure and 4C figure represents the second different image outputs 42 respectively, 43, for the second Narrow Field Of Vision image 22 of reducing, (dotted line frame 92 represents the scope of the second Narrow Field Of Vision image 22 after reducing to second image output 42, supplement the gap of region 91 for the second Narrow Field Of Vision image 22 after filling up the second image output 42 and reducing) with the corresponding region, the wide visual field 73 of the second wide field image 12 in conjunction with image, and in 4C figure, this second image output 43 produces by merging through the second wide field image 13 of convergent-divergent and distortion and the Narrow Field Of Vision corresponding region (not being shown in figure) of the second Narrow Field Of Vision image 23, the second image output 43 is now except treating tracing object 30, also there is leg-of-mutton object in its background, and it is known from 4B figure and 4C figure, treat that the change in size degree of tracing object 30 is less, but outside scenery but can have a greater change.
Further instruction, as shown in 4D figure, if during the size of the wide area of visual field size 71 in the second wide field image 13 comparatively close to reference zone 82, now first with the ratio of reference zone 82, convergent-divergent and deformation process are carried out to the second wide field image 13 according to this wide area of visual field size 71, if when user is for amplifying 1.5 times by this second image output 44, now the Narrow Field Of Vision corresponding region (not being shown in figure) of the second Narrow Field Of Vision image 23 this wide area of visual field size 71 corresponding is amplified simultaneously and is adjusted to corresponding size, as 1.5 times, and visual fusion is carried out in this Narrow Field Of Vision corresponding region of amplifying and the second wide field image 13, the overall image quality after 1.5 times is amplified to improve the second image output 44.
In enforcement, image-zooming and deformation unit 80 can give tacit consent to a ratio threshold value, when image-zooming and deformation unit 80 judge until tracing object 30 the second wide field image 12 wide area of visual field size 71 relatively reference zone 82 time, and when the proportional difference of tracing object 30 between wide area of visual field size 71 and reference zone 82 is less than ratio threshold value, then this second wide field image 12 and the second Narrow Field Of Vision image 22 are merged to produce the first image output 41, then carry out follow-up image procossing operation.
