Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The action execution subject of each step in the image browsing method provided by the embodiment of the present invention may be an image browsing system provided by the embodiment of the present invention, and the system may be built in a computer, a server, and the like. For convenience of description, the action execution subject of each step in the image browsing method provided by the embodiment of the present invention is set as an image browsing system provided by the embodiment of the present invention, which is simply referred to as an image browsing system.
Referring to fig. 1, fig. 1 is a flowchart illustrating an image browsing method according to an embodiment of the present invention.
The image browsing method provided by the embodiment of the invention can comprise the following steps:
step S101: and determining a browsing area in the image to be browsed, wherein the browsing area is an area containing a browsing object in the image to be browsed.
In practical applications, the image browsing system may first determine a browsing area in the image to be browsed, where the browsing area is an area including a browsing object in the image to be browsed, for example, for a power transmission line diagram, the browsing object of the diagram is an insulator, a vibration damper, or the like, a sky or the like in the diagram is not a browsing object, and correspondingly, the browsing area is an area including an insulator, an area including a vibration damper, or the like, and an area including a sky alone is not a browsing area of the diagram; in a specific application scenario, the browsing area may also be a fixed area that needs to be browsed and is preset in the image to be browsed, such as an area in a certain range in the center of the image. It should be noted that the number of browsing areas in the image to be browsed is determined by the number of browsing objects in the image to be browsed and a determination method, where the determination method is a method for determining browsing areas, and assuming that there are two browsing objects in the image to be browsed, if the determination method is that one browsing object corresponds to one browsing area containing the browsing object, the number of browsing areas in the image to be browsed is 2.
Step S102: and dividing each browsing area into corresponding browsing sub-areas, wherein each browsing sub-area can be completely displayed by the display area.
After the image browsing system determines the browsing area, each browsing area can be divided into corresponding browsing sub-areas, and each browsing sub-area can be completely displayed by the display area. Because the browsing area is an area containing the browsing object, the browsing sub-area divided by the browsing area is also a sub-area containing the browsing object; in addition, each browsing sub-area can be completely displayed by the display area, so that the number of the browsing sub-areas obtained by dividing any browsing area is determined by the browsing area, the display area and the dividing method, that is, after the browsing area, the display area and the dividing method are determined, the number of the browsing sub-areas obtained by dividing any browsing area is correspondingly determined. Certainly, the image browsing system can also receive a division rule input by the outside in the process of dividing the browsing area, and divides the browsing area according to the division rule input by the outside, so that the control requirement of the outside on the process of dividing the browsing area is met.
Step S103: and sequentially pushing each browsing sub-area to the display area so as to enable the outside to completely view the browsing sub-areas in the display area.
After obtaining all the browsing sub-regions, the image browsing system can sequentially push each browsing sub-region to the display region, so that the outside can completely view the browsing sub-regions located in the display region. In the process of pushing the browsing sub-regions, the image browsing system may sequence the browsing sub-regions first, and then sequentially push the browsing sub-regions to the display region according to a sequencing result, for example, sequencing from left to right, from top to bottom, and the like, where a sequencing rule may be determined according to actual needs, and taking an image to be browsed as an example of a power transmission line diagram, the sequencing rule may be to sequence the browsing sub-regions along an extension direction of the power transmission line.
The invention provides an image browsing method, which comprises the steps of determining a browsing area in an image to be browsed, wherein the browsing area is an area containing a browsing object in the image to be browsed; dividing each browsing area into corresponding browsing sub-areas, wherein each browsing sub-area can be completely displayed by the display area; and sequentially pushing each browsing sub-area to the display area so as to enable the outside to completely view the browsing sub-areas in the display area. The image browsing method provided by the invention realizes automatic pushing of the image to be browsed according to the browsing object, and has better applicability compared with the prior art in which the image to be browsed is manually moved. In summary, the image browsing method provided by the invention has better applicability.
In the image browsing method provided in the embodiment of the present invention, step S101 determines a browsing area in an image to be browsed, and specifically, the method may include:
and identifying each browsing object of the image to be browsed based on a target detection algorithm, and taking an area containing each browsing object as a browsing area of the browsing object.
In practical application, the image browsing system may identify each browsing object in the image to be browsed based on a target detection algorithm, and then take an area containing each browsing object as a browsing area of the browsing object; in a specific application scene, the minimum area containing each browsing object can be used as the browsing area of the browsing object, and because the browsing area is the minimum area containing the browsing object, the influence of non-browsing objects in the browsing area can be reduced to a certain extent, and the probability of outside browsing the non-browsing area is further reduced to a certain extent. Of course, the detailed relationship between the browsing area and the browsing object may be determined according to actual needs, for example, the browsing area is a rectangular area containing the browsing object, and the invention is not limited in this respect.
In the image browsing method provided in the embodiment of the present invention, step S101 determines a browsing area in an image to be browsed, and specifically, the method may include:
and determining each browsing area in the image to be browsed based on an image segmentation algorithm.
In practical application, the image browsing system can determine each browsing area in the image to be browsed based on the image segmentation algorithm, and the image browsing system can quickly determine the browsing area by means of the image segmentation algorithm, so that the browsing efficiency of the image browsing method provided by the embodiment of the invention is improved to a certain extent.
In the image browsing method provided in the embodiment of the present invention, step S101 determines a browsing area in an image to be browsed, and specifically, the method may include:
and receiving each browsing area in the image to be browsed marked by the outside.
In practical application, the browsing area may be determined by the outside in a form of a label, and at this time, the image browsing system may directly receive each browsing area in the image to be browsed labeled by the outside, so that the outside can plan the browsing area according to the intention of the outside.
In the image browsing method provided in the embodiment of the present invention, in the step S102, each browsing area is divided into corresponding browsing sub-areas, which may specifically be:
for each browsing area, determining a circumscribed rectangle of the browsing area;
dividing the circumscribed rectangle into a plurality of browsing sub-regions based on a dividing formula;
the division formula is as follows:
wherein the content of the first and second substances,
denotes rounding up, Nw×NhIndicates the total number of browsing subareas divided by the browsing area, wW-wΔIndicates the width, h, of each viewed sub-regionW-hΔThe height of each of the viewing sub-areas is indicated,
the width of the circumscribed rectangle representing the viewing area,
height, w, of a circumscribed rectangle representing the viewing areaWIndicates the width of the display area, hWIndicating the height of the display area, wΔ＜wWAnd h isΔ＜hW。
In practical application, the display area is generally a rectangular area, and at this time, the shape of the browsing sub-area can also be set to be rectangular, and the browsing area is divided into rectangular browsing sub-areasThe process of the domain can refer to this embodiment, and is not described here. It should be noted that in the process of dividing the browsing area, the outside world can adjust wΔAnd hΔThe shape of the partitioned browsing sub-area is controlled by the value of (A); in addition, in a specific application scenario, a situation may occur in which the browsing area itself can be completely displayed by the display area, where N isw、NhIs less than 1, after rounding up, Nw、NhThe values of (1) are all 1, that is, one browsing area is divided into one browsing sub-area, and at this time, the browsing area can be directly used as the browsing sub-area.
In the image browsing method provided in the embodiment of the present invention, step S103 sequentially pushes each browsing sub-area to the display area, which may specifically be:
determining a reference point of each browsing subarea;
determining a reference point of the display area;
and sequentially pushing each browsing subarea to the display area, and controlling the reference point of the browsing subarea to coincide with the reference point of the display area.
In the case that the display area and the browsing sub-area are both rectangular areas, the process of pushing each browsing sub-area to the display area by the image browsing system may be as shown in the embodiment of the present invention, and in practical application, the image browsing system may also sequence the reference points of all browsing sub-areas belonging to the same browsing area, and store the sequenced reference points in the form of a point set; correspondingly, in the process of pushing each browsing sub-region to the display region, the browsing sub-regions can be pushed according to the sequence of the reference points in the point set.
In a specific application, the reference point in the embodiment of the present invention may be a central point, and correspondingly, the process of determining the central point of each browsing sub-area may specifically be:
determining a central point of each browsing sub-area based on a central point formula;
wherein, the formula of the central point is as follows:
In the image browsing method provided in the embodiment of the present invention, after dividing each browsing area into corresponding browsing sub-areas, and before sequentially pushing each browsing sub-area to the display area, the method may further include:
and for each browsing sub-region, judging whether the ratio of the area of the browsing region to which the browsing sub-region belongs in the browsing sub-region to the area of the browsing sub-region is greater than or equal to a preset area ratio threshold, and if not, not pushing the browsing sub-region to a display region.
In practical applications, in order to reduce the probability that the browsing effect is affected by the browsing sub-region containing a large number of non-browsing objects, the image detection system may not push the browsing sub-region containing a large number of non-browsing objects to the display region, and the specific implementation process may refer to this embodiment. For example, when a line passing through the diagonal of the image to be browsed is taken as the browsing area, if the browsing sub-area is not selectively avoided, the whole image to be browsed can be browsed, and if the browsing sub-area without the line can be avoided, the image can be browsed only along the line.
In the image browsing method provided in the embodiment of the present invention, in the process of sequentially pushing each browsing sub-area to the display area in step S103, the method may further include:
and judging whether control information sent by the outside is received, if so, controlling the pushing of the browsing subarea according to the control information.
In practical application, in order to meet the requirement that the outside world controls the display process of the browsing sub-regions in the display region according to actual needs, the image detection system can also judge whether control information sent by the outside world is received in real time in the process of sequentially pushing each browsing sub-region to the display region, if so, the pushing of the browsing sub-regions is controlled according to the control information, wherein the control information can be used for pausing, switching the current browsing sub-region, selecting a certain browsing sub-region to be directly displayed in the display region and the like.
In the image browsing method provided in the embodiment of the present invention, in the process of sequentially pushing each browsing sub-area to the display area in step S103, the method may further include:
establishing two matrixes which are respectively marked as a time difference matrix T and an attention matrix A, wherein T and A are both w multiplied by h matrixes, w is the width of an image to be browsed, and h is the height of the image to be browsed;
the time for starting to browse the image to be browsed is recorded as tau0The time for starting to browse the image to be browsed is the time for any pixel in the image to be browsed to appear in the display area for the first time;
by means of the elements T in the time difference matrix Ti,jRecording a pixel I in an image to be browsed in the first browsingi,jTime of and τ0A difference of (d);
by means of the element A in the attention matrix Ai,jRecording a pixel I in an image to be viewedi,jA browsing duration of pixel Ii,jThe total length of stay in the display area.
In practical application, the data in the image to be browsed may be recorded by using a matrix, and the specific process refers to this embodiment, but of course, other methods for recording the data in the image to be browsed may also be available, such as recording the occurrence time and departure time of each image pixel in the display area, and the present invention is not limited herein.
In the image browsing method provided in the embodiment of the present invention, in the process of sequentially pushing each browsing sub-area to the display area, the method may further include:

establishing two matrixes which are respectively marked as an area distribution matrix R and a browsing matrix V, wherein R and V are both matrixes of wx h, w is the width of an image to be browsed, and h is the height of the image to be browsed;
initializing the element values in both R and V to 0;
setting the element value of an image pixel belonging to the browsing area in R to be 1;
setting the element value of the image pixel with the browsing time length larger than the preset browsing time length threshold value in V as 1;
determining an image pixel having the same element value of 1 in R and V as an effective image pixel;
determining the ratio of the total number of effective image pixels to the total number of elements with the value of 1 in R as the browsing rate of the image to be browsed;
