Example 1
As shown in fig. 3, a method for capturing a long screen shot is provided in an embodiment of the present invention, and the method specifically includes the following steps:
step S110: comparing the first full screen screenshot with the second full screen screenshot, and calculating the displacement of the second full screen screenshot relative to the first full screen screenshot.
Specifically, the composition of the current screen long screenshot mainly comprises two full screen shots before and after the screen slides, namely the two full screen shots are spliced together to obtain the full screen screenshot, so before the step of comparing the first full screen screenshot with the second full screen screenshot and calculating the displacement of the second full screen screenshot relative to the first full screen screenshot is executed, the method further comprises the following steps: intercepting a screen interface before screen sliding to acquire a first full screen capture, and intercepting a screen interface after screen sliding to acquire a second full screen capture.
After the first full screen capturing and the second full screen capturing are sequentially obtained through the steps of the method, the steps of the method can be spliced based on the first full screen capturing and the second full screen capturing, so that the final long screen capturing is obtained. As shown in fig. 4, a final screen shot is obtained by the method of the present screen shot, first, this step is performed to "compare the first full screen shot with the second full screen shot, calculate the displacement of the second full screen shot relative to the first full screen shot", and the specific process includes:
step S111: and dividing the second full screen shot into a first area, a second area, a third area and a fourth area in turn along the longitudinal direction of the screen.
Step S112: and comparing the first full screen shot with the second area through a template matching algorithm, and finding out the position of the second area in the first full screen shot so as to calculate the displacement.
As shown in fig. 5, it is a screen interface before screen sliding that is intercepted to obtain the resulting first full screen shot 100. As shown in fig. 6, the second full screen shot 200 is obtained by capturing a screen interface after the screen slides, according to the above method steps, the second full screen shot 200 is divided into a first area 201, a second area 202, a third area 203 and a fourth area 204 in turn along the longitudinal direction of the screen, then, by means of a template matching algorithm (the template is a known small image, the template matching is searching for a target in a large image, the target is known to have the same size, direction and image as the target in the image, the target can be found in the image by a certain algorithm, and the coordinate position of the target is determined) compared with the first full screen shot 100 and the second area 202 (the reason that the first area 201 is easy to generate an interference area (the top and bottom contents of the full screen shot are often the same due to the existence of the same background), the third area 203 and the fourth area 204 are often newly generated contents, and the displacement is not easy to calculate the displacement, so that the position of the second area 202 in the first full screen shot 100 is found. As shown in fig. 5, the area 101 in the figure is matched with the second area 202, that is, the position of the area 101 in the figure is the position of the second area 202 in the first full screen 100, and finally, the displacement Y of the second full screen 100 relative to the first full screen 100 is calculated by calculating the position of the area 101 in the figure.
Step S120: and acquiring a connection line between the first full screen shot and the second full screen shot according to the displacement.
Specifically, after the displacement Y of the second full screen shot 200 relative to the first full screen shot 100 is calculated through the steps of the method, a connection line between the first full screen shot 100 and the second full screen shot 200 can be obtained according to the displacement Y, the connection line specifically comprises a first connection line and a second connection line, as shown in fig. 5, the first connection line 11 is located in the first full screen shot 100, and the position of the first connection line can be obtained by subtracting the displacement Y from the height H of the first full screen shot 100; as shown in fig. 6, the second connecting line 21 is located in the second full screen 200, and is located at a position where the height H of the first area is subtracted from the height H of the second full screen 200 1 (H in the present embodiment since the second full screen shot in the present embodiment is divided into the first region, the second region, the third region, and the fourth region in this order in the longitudinal direction of the screen 1 =1/4H).
Thus, as shown in fig. 7, the specific process of executing this step of "acquiring the line of engagement between the first full screen shot and the second full screen shot according to the displacement" includes:
step S121: the displacement is subtracted from the height of the first full screen shot to obtain the location of the first line of engagement.
Step S122: subtracting the height of the first area from the height of the second full screen shot to obtain the position of the second connecting line.
Step S130: and comparing and checking the connection line by the preset checking height, and splicing the first full screen shot and the second full screen shot by the connection line only when the comparison and the checking pass, so as to obtain the screen length screenshot.
Specifically, after the positions of the connecting lines (including the first connecting line 11 and the second connecting line 21) between the first full screen shot and the second full screen shot are obtained through the steps of the method, the connecting lines (including the first connecting line 11 and the second connecting line 21) can be compared and checked through a preset checking height, as shown in fig. 8, and the specific process includes:
step S131: and respectively marking out a comparison range of the first connecting wire and a comparison range of the second connecting wire by taking a preset checking height as a reference.
Step S132: and comparing the content included in the comparison range of the first connecting wire with the content included in the comparison range of the second connecting wire through a template matching algorithm so as to realize comparison and verification of the connecting wire.
The pictures are not spliced directly, but the comparison range of the first connecting wire 11 is marked by taking the preset checking height X as a reference, as shown in fig. 9, specifically, the position of the first connecting wire 11 is shifted upwards by the preset checking height X to the position of the first connecting wire 11 is shifted downwards by the preset checking height X (namely, the area H-Y+X- & gt surrounded by two broken lines in fig. 9)>H-Y-X); as shown in fig. 10, the comparison range of the second connecting wire 21 is defined, specifically, the position of the second connecting wire 21 is shifted upward by a preset check height X to the position of the second connecting wire 21 is shifted downward by a preset check height X (i.e.Region H-H enclosed by two dotted lines in FIG. 10 1 +X-->H-H 1 -X). Next, the comparison range of the first connecting line 11 (i.e., the region H-Y+X-surrounded by two dotted lines in FIG. 9) is compared by the template matching algorithm>H-Y-X) includes a comparison range of the content and the second connecting line (i.e., a region H-H surrounded by two broken lines in FIG. 10) 1 +X-->H-H 1 -X) comparing the content comprised in the link line to achieve a comparison check of the link line. At this time, if the previously calculated displacement Y value is accurate (the corresponding obtained join line is also accurate), the comparison range of the first join line 11 (i.e., the region H-Y+X- > surrounded by two broken lines in FIG. 9)>H-Y-X) includes a comparison range of the content and the second connecting line (i.e., a region H-H surrounded by two broken lines in FIG. 10) 1 +X-->H-H 1 X) should be identical, and comparing the two areas by the template matching algorithm, if the relative displacement is returned to be 0, the displacement Y calculated before is correct (the corresponding acquired connecting line is also accurate), and the first full screen screenshot and the second full screen screenshot are spliced by the connecting line, so that the accurate long screen screenshot can be finally acquired.
In addition, as shown in fig. 11, after the step of performing the present step of performing the comparison and verification on the connection line by the preset verification height, only when the comparison and verification pass, the first full screen capturing and the second full screen capturing are spliced by the connection line, so as to obtain a long screen capturing, the method further includes:
step S140: if the comparison verification is not passed, the displacement of the second full screen capture relative to the first full screen capture is recalculated through a standby scheme, and a new connection line is obtained, so that after the new connection line passes the comparison verification, the first full screen capture and the second full screen capture are spliced through the new connection line, and a screen length capture is obtained.
Specifically, if the return relative displacement is 0, it indicates that the displacement Y calculated before is correct (the corresponding acquired connection line is also accurate), and indicates that the first full screen shot and the second full screen shot are spliced through the connection line, so that an accurate screen length screenshot can be finally acquired. Otherwise, if the return relative displacement is not 0, the calculated displacement Y is wrong, the first full screen screenshot and the second full screen screenshot cannot be spliced through the connecting line (at this time, if the first full screen screenshot and the second full screen screenshot are spliced through the connecting line, splicing errors are generated), at this time, the displacement of the second full screen screenshot relative to the first full screen screenshot can be recalculated through a further new scheme, namely, a standby scheme, and a new connecting line is acquired, so that after the new connecting line passes the comparison verification, the first full screen screenshot and the second full screen screenshot are spliced through the new connecting line, and a screen length screenshot is obtained. As shown in fig. 12, the standby scheme preferably includes the steps of:
step S141: and dividing the second full screen shot into a fifth area, a sixth area, a seventh area, an eighth area and a ninth area in turn along the longitudinal direction of the screen, wherein the sixth area and the seventh area are combined together to form a comparison area.
Step S142: and comparing the first full screen shot with the comparison area through a template matching algorithm, and finding out the position of the comparison area in the first full screen shot so as to calculate the displacement.
The basic principle of calculating the displacement of the second full screen capturing relative to the first full screen capturing through the standby scheme is the same as that of the original scheme, and the difference is that the standby scheme improves the calculation precision of the displacement by changing the area for comparison in the second full screen capturing (increasing the area of the comparison area), so as to continuously perfect the long screen capturing to obtain a correct result. Thus, other alternative schemes may be implemented similarly to those skilled in the art.
