FIG. 1 illustrates a schematic diagram of an exemplary operating environment 100 in which embodiments of the present application can be implemented.
Referring to fig. 1, the operating environment 100 includes a display 110, a controller 120, and an operating device 130, where the display 110 and the operating device 130 are both connected to the controller 120, the controller 120 can be controlled by the operating device 130, the display 110 can display a human-computer interaction interface, and the operating device 130 may specifically include a mouse and a keyboard, and may also be integrated with the display 110 to form a touch screen with display and control functions.
The method for determining visual sensitivity in the embodiment of the present application may be performed in the operating environment 100, and may be performed by the controller 120 in fig. 1, specifically, by the interaction of the controller 120 with the display 110 and the operating device 130.
The method comprises the following steps:
s1: constructing a basic pattern and identifying the pattern.
Fig. 2 shows a schematic diagram of a method for constructing a basic pattern and recognizing a pattern in an embodiment of the present application. In fig. 2, a denotes a first display area, B denotes a fill line, C denotes an outline, and D denotes a basic pattern or recognition pattern formed by the build.
Referring to fig. 2, the basic pattern is a pattern as a substrate, and the recognition pattern is a pattern recognized by a tester.
The basic pattern and the identification pattern both contain two attributes of outline and content. Wherein the outline embodies the two-dimensional shape of the basic pattern or the identification pattern. The contents of the basic pattern and the identification pattern are a plurality of parallel lines, and in the determined basic pattern or the identification pattern, the line widths of the lines are the same, and the intervals between adjacent lines are the same, namely the line widths of the lines and the intervals between adjacent lines are determined. The content of the basic pattern and the identification pattern fills the contour, and it can also be understood that a filling line formed by lines is added in the contour.
In the application, the ratio of the line width of the lines in the content of the basic pattern to the distance between the adjacent lines is the basic ratio, and the ratio of the line width of the lines in the content of the identification pattern to the distance between the adjacent lines is the identification ratio.
Before the basic pattern and the recognition pattern are constructed, the controller 120 is first controlled by the operating device 130, so that the controller 120 controls the display 120 to provide a first display area, which is specifically rectangular, but may be any other shape such as a circle, an ellipse, or an irregular pattern.
The basic pattern and the identification pattern are constructed in the first display area, and the construction principles are substantially the same, and the construction principles of the basic pattern and the identification pattern are described in detail below.
In the first display region, the background color of the first display region is set by the operation device 130, and then the color of the filling line is set, and the background color is different from the color of the filling line, for example, the background color of the first display region is set to white and the color of the filling line is set to black.
After the background color of the first display area and the color of the filling line are set, the filling line is added in the first display area through the operation equipment 130, and the filling line is a filling line which fills the first display area and can also be understood as a filling line which is added in the first display area and formed by the line.
When adding the filling lines in the first display area, the setting angle, the line width and the space of the filling lines can be set.
The posture of the filling line in the first display area can be experienced by setting the angle, taking the display 110 in a rectangular shape in the related art as an example, when the display 110 is vertical and long-edge horizontal, if the first display area is also vertical and long-edge horizontal, the posture of the filling line which can be set up by default is 0 degree, the setting angle can be 0 degree to 360 degrees, the specified setting angle represents the angle between the filling line and the filling line in the default posture under the setting angle, for example, the setting angle of the filling line is 30 degrees, and the included angle between the filling line and the vertical filling line is 30 degrees.
The line width is the width of the filling line, and the space is the space between two adjacent lines in the filling line. The setting mode is more conventional and is not specifically described.
After the filling lines are added in the first display area, an outline can be determined in the first display area through the operation device 130, and all the filling lines outside the outline are removed by a cutting command, and only the filling lines inside the outline are reserved. For example, a circular outline is determined in the first display area of the rectangle, and all the filling lines outside the circular outline are removed by a cropping command, so that only the filling lines inside the circular outline are retained.
The outline can be determined by drawn outline edge lines, if the outline edge lines are the same as the ground color set in the first display area, the outline edge lines are not deleted, otherwise, the outline edge lines are deleted, and only filling lines and no outline lines are included when the finally formed pattern is displayed in the first display area.
So far, the construction of the designated outline and the pattern of the designated content is completed, the basic pattern and the identification pattern are constructed in the mode, and only different outlines and different contents need to be set. It should be understood that, in a group of basic patterns and identification patterns used cooperatively, the arrangement angles of the filling lines need to be the same, so as to ensure that the filling lines in the basic patterns and the identification patterns can be parallel when the identification patterns are added to the basic patterns.
It should be understood that the above description is only one construction of the basic pattern and the recognition pattern, and the construction can be implemented in conventional drawing software, such as CAD, drawing software, and the like. The basic pattern and the recognition pattern may be constructed in other manners, such as directly drawing the outline and adding filling lines with specified setting angles, line widths and intervals in the outline, or directly drawing the outline and lines in the outline in a drawing manner. That is, the present application does not limit the manner of constructing the basic pattern and the identification pattern, and only needs to be able to construct the basic pattern and the identification pattern as disclosed above.
S2: the formulated identification pattern is added to a specified location of the specified base pattern in response to the graphic construction instructions to construct the formed sensitivity determination pattern.
Fig. 3 shows a schematic diagram of a method for constructing a sensitivity determination pattern in an embodiment of the present application. In fig. 3, M denotes a second display region, N denotes a basic pattern, P1, P2 respectively identify two recognition patterns, and Q denotes a sensitivity determination pattern.
Referring to fig. 3, the sensitivity determining pattern includes a designated basic pattern and a plurality of designated recognition patterns, the plurality of recognition patterns are respectively located at different positions of the designated basic pattern, and there is no intersection between any two recognition patterns. Generally, the area of the basic pattern is much larger than that of a single recognition pattern, so that the basic pattern can accommodate a plurality of designated recognition patterns in the above manner.
The graph construction instruction is acquired by the operating device 130, the graph construction instruction is a set of control instructions, and the graph construction instruction specifically includes a basic pattern acquisition instruction, an identification pattern acquisition instruction, and an adding position acquisition instruction, where one identification pattern acquisition instruction corresponds to one adding position acquisition instruction.
Before the sensitivity determination pattern is constructed, the display 110 is first controlled by the operation device 130 to provide the second display region, and the ground color of the second display region is set to be identical to the ground color of the first display region, at which time the display 110 provides the second display region, and the ground color of the second display region is identical to the ground color of the first display region.
Then, the basic pattern acquiring instruction is acquired through the operating device 130, the controller 120 acquires the constructed specified basic pattern based on the basic pattern acquiring instruction, and adds the basic pattern to the second display area, at this time, the display 110 can provide the second display area with the bottom color consistent with that of the first display area, and the specified position in the second display area contains the specified basic pattern. The process may be understood as dragging a designated basic pattern to a designated position within the second display area.
Then, the identification pattern obtaining instruction is obtained through the operation device 130, the controller 120 obtains a designated identification pattern based on the identification pattern obtaining instruction, and adds the identification pattern to a designated position in the second display area and the basic pattern area that has been added, at this time, the display 110 can provide the second display area with the bottom color consistent with the bottom color of the first display area, the designated position in the second display area contains the designated basic pattern, and the area of the designated basic pattern contains the designated identification pattern. The process may also be understood as dragging a specified basic pattern to a specified position within a specified basic pattern area.
When the method is applied, the sensitivity determination pattern comprises a basic pattern and a plurality of identification patterns, and the identification ratios of any two identification patterns are different, so that the difficulty of identifying the identification patterns in the sensitivity determination pattern is different.
The basic ratio and the recognition ratio, the line width and the space of the filling lines, the area size of the basic pattern, the number of the recognition patterns in the sensitivity determination pattern, the viewing distance of the sensitivity determination pattern and other data can be set according to the experience of a person skilled in the art, and can be known through a limited number of experiments, only different recognition patterns need to have different recognition degrees in the basic pattern, and related data are not disclosed here.
Based on the above, the construction of the sensitivity determination pattern has been described.

Fig. 7 shows a fourth schematic diagram of a sensitivity determination pattern in an embodiment of the present application. In fig. 7, the basic pattern is a forest pattern, and the identification pattern is a leopard pattern.

The sensitivity determination pattern can also be displayed in other modes such as projection and the like or printed into a paper picture for a tester to watch, so that the test of the visual sensitivity of the tester is realized, and the test process of the visual sensitivity is more flexible and convenient. And the construction mode of the sensitivity determination pattern is simple in principle and simple and convenient to operate.
