Based on above-mentioned mobile terminal hardware configuration and communications network system, each embodiment of the inventive method is proposed.

As shown in fig. 6, first embodiment of the invention proposes a kind of method for realizing long sectional drawing, this method specifically includes following Step：

Step S110：Matching characteristic block line is carried out between the preceding full screen printscreen and rear full screen printscreen of the first linking figure, To form the second linking figure.

Specifically, so that fixed background scene is chat scenario as an example, as shown in figure 9, the left side of the first linking figure is merely Preceding full screen printscreen under its scene, right side be chat scenario under rear full screen printscreen, by the figure to the preceding full screen printscreen Matching characteristic block line is carried out with the rear full screen printscreen, the second linking figure as shown in Figure 10 can be ultimately formed.And how by it is preceding, Full screen printscreen finally gives the second linking figure afterwards, as shown in fig. 7, specifically can be realized by following steps：

Step S111：By the way that preceding full screen printscreen is connected into figure to form first laterally side by side successively with rear full screen printscreen.

Specifically, as shown in figure 9, the main preceding full screen printscreen and the rear full screen printscreen on right side by left side of the first linking figure Formed laterally side by side successively, because the sectional drawing time of preceding full screen printscreen is, prior to the time of rear full screen printscreen, to change speech certainly It, also by two full screen printscreens, in chronological sequence order is formed laterally side by side successively for the first linking figure, so, , also can be by will be multiple full frame if the multiple full screen printscreens for entering to be about to more than two backward are merged into the operation of long sectional drawing Sectional drawing in chronological sequence order form the first linking figure laterally side by side successively, i.e., as shown in figure 14, this first be connected figure by In chronological sequence order is formed four full screen printscreens laterally side by side successively.

Step S112：All it is mutually matched by what contrast conting obtained between the preceding full screen printscreen and the rear full screen printscreen Characteristic block, to constitute the characteristic block set of matches between the preceding full screen printscreen and the rear full screen printscreen.

Specifically, by calculating is compared between the preceding full screen printscreen and the rear full screen printscreen, can obtain both it Between all characteristic blocks being mutually matched, these characteristic blocks being mutually matched except including correspond be mutually matched except in the case of, Also include situations below：The same characteristic block of preceding full screen printscreen can find multiple matching features in rear full screen printscreen Block, now, this feature block of preceding full screen printscreen corresponds to combine with the plurality of characteristic block of rear full screen printscreen respectively forms many To the characteristic block being mutually matched；Multiple characteristic blocks of preceding full screen printscreen simultaneously with mutual an of characteristic block in rear full screen printscreen Match somebody with somebody, now, the plurality of characteristic block of preceding full screen printscreen corresponds to combine with this feature block of rear full screen printscreen respectively forms many To the characteristic block being mutually matched.In the present embodiment, there are 11 characteristic blocks can be on the right side of Fig. 9 in the preceding full screen printscreen on the left of Fig. 9 Rear full screen printscreen in find the characteristic block being mutually matched therewith, form 15 pairs of characteristic blocks for being mutually matched altogether between the two, The characteristic block that 15 couple is mutually matched constitutes a characteristic block set of matches A.

Step S113：Enter between the characteristic block being mutually matched on the first linking figure to each pair that this feature Block- matching is concentrated Row same position point line, to complete matching characteristic block line, and then forms the second linking figure.

Specifically, as shown in figure 9, in the first linking figure, left side is preceding full screen printscreen, right side is rear full screen printscreen. After the first linking figure and characteristic block set of matches A is obtained, just same position point link process can be carried out in the first linking figure, Same position point is carried out between the characteristic block being mutually matched on the first linking figure to each pair in this feature Block- matching collection A Line, to form the second linking figure, the second linking figure is as shown in Figure 10.In the present embodiment, the same position point line has Body is characterized block central point line, and to those skilled in the art, the same position point line can also use characteristic block Any identical bits angle setting line is substituted.

Step S120：Unrelated line exclusion and fore-and-aft distance value histogram are carried out to all lines in the second linking figure Statistics, to acquire the picture relative displacement between preceding full screen printscreen and rear full screen printscreen.

Specifically, the relative position of picture between the preceding full screen printscreen and the rear full screen printscreen on right side to acquire left side Move, need first to carry out unrelated line exclusion to all lines in the second linking figure, made with excluding as far as possible under same background Into the interference of feature Block- matching, fore-and-aft distance value histogram statistics then are carried out to remaining all lines again, with more intuitively Correct picture relative displacement between the two is found out, as shown in figure 8, can specifically be completed by following operating procedure：

Step S121：The fore-and-aft distance value filtered out between all two end points on the second linking figure falls into default mistake Line in poor scope.

Specifically, the default error range can be preset according to actual needs, it is however generally that, the default error model Enclosing can be set between 0 to 20 pixels, as shown in figure 11, by the way that second is connected between all two end points on figure The line that fore-and-aft distance value is fallen into default error range is all filtered out, and its can be excluded under fixed background scene as far as possible identical The interference of feature Block- matching that background is caused because when by preceding full screen printscreen with after full screen printscreen form rank laterally side by side successively After map interlinking, the multipair characteristic block being mutually matched that both occur due to same background, its longitudinal coordinate between any two is general Will not be shifted (also can not possibly be excessive even if offsetting), simultaneously as the general screenshotss of user are obtained after preceding full screen printscreen, meeting Picture is moved up full screen printscreen after being carried out again after one section of larger distance interception (if in general, only by picture slightly on The interception of full screen printscreen, can cause the difference between forward and backward full screen printscreen very few, now merge the two after just being carried out after shifting Forward and backward full screen printscreen has little significance), thus, the feature Block- matching of same background appearance is really not due to, between any two vertical To distance value be certainly than larger, will not be too small due to fore-and-aft distance value and fall into this and preset in error range.

Step S122：Filter out all where lateral rear full screen printscreen where preceding full screen printscreen on the second linking figure Roll line obliquely.

Specifically, before being obtained due to the general screenshotss of user after full screen printscreen, picture can be moved up after one section of larger distance The interception of full screen printscreen after carrying out again, thus, as shown in figure 11, if actually same characteristic block be mutually matched a pair it Between, it is located at the position of the characteristic block of full screen printscreen behind right side and is certain to be higher than the position for being located at the characteristic block of full screen printscreen before left side Put, i.e., line between the two is rolled obliquely where lateral rear full screen printscreen where preceding full screen printscreen, in other words, such as Figure 12 It is shown, by filtering out all inclinations where lateral rear full screen printscreen where preceding full screen printscreen on the second linking figure obliquely Line, can further reduce the interference that unrelated line is caused.

Step S123：The fore-and-aft distance value progress statistics with histogram of remaining all lines on the second linking figure is looked for Go out the most fore-and-aft distance value of occurrence number, to acquire the relative position of the picture between preceding full screen printscreen and rear full screen printscreen Move.

Specifically, are filtered into remaining all lines first time includes as a line set B, i.e. line set B All lines as shown in figure 11, will further filter remaining all lines as a line set C, i.e. the line set C includes all lines as shown in figure 12, and either the fore-and-aft distance value to all lines in line set B enters column hisgram Such as statistics, i.e., as shown in figure 13, or carry out statistics with histogram, i.e., to the fore-and-aft distance value of all lines in line set C Shown in Figure 14, fore-and-aft distance value D2 values are that occurrence number is most, thus fore-and-aft distance value D2 values be before full screen printscreen and From the point of view of picture relative displacement between full screen printscreen afterwards, the actual conditions with reference to Figure 11 and Figure 12, fore-and-aft distance value D2 values are produced Line be also line between actually same characteristic block be mutually matched a pair.

Step S130：According to the picture relative displacement, got rid of by calculating between preceding full screen printscreen and rear full screen printscreen Repeating part, preceding full screen printscreen and rear full screen printscreen are spliced into the long sectional drawing of a width.

Specifically, when operating the preceding full screen printscreen that obtains in the first linking figure shown in Fig. 9 left side successively according to above-mentioned steps After picture relative displacement between the rear full screen printscreen on right side, just it can be removed according to the picture relative displacement by calculating Fall the repeating part between the preceding full screen printscreen and the rear full screen printscreen, the preceding full screen printscreen and the rear full screen printscreen is final The long sectional drawing of a width is spliced into, the long sectional drawing is finally as shown in figure 15.Consequently, it is possible to just complete to realize two under fixed background scene Individual forward and backward full screen printscreen is spliced into all processes of the operation of a long sectional drawing.
