and step 306, acquiring a coordinate set of the labeling area, and screening a second coordinate point set in the coordinate set according to the first coordinate point set to determine the target labeling area.
In an embodiment of the present application, a coordinate system is configured in a displayed target interface, and a first coordinate point set is determined in the coordinate system according to first input position information, and the first coordinate point set is a base point of the first input position information. Specifically, the first input position information is a rectangular track, and the first coordinate point set is a coordinate set of four endpoints of the rectangular track. The marking area corresponds to character information in the target interface one by one, a coordinate set of the marking area is determined, the coordinate set of the marking area is screened according to the first coordinate point set, a second coordinate point set which is closest to the first coordinate point set is found, the number of coordinate points in the second coordinate point set is the same as that of the coordinate points in the first coordinate point set, and the target marking area in the marking area of the target interface can be determined according to the second coordinate point set.
The coordinate point of each marked area in the target interface is obtained first, and therefore the coordinate set of the marked areas is obtained. And then, four coordinate points of the first input track are obtained to obtain a first coordinate point set, the four coordinate points are coordinates of four vertexes of the first input track, so that the position and the coverage range of the first input in the target interface can be determined, and a second coordinate point in the coordinate set is screened through the four coordinate points, so that the target labeling area is determined. By configuring a coordinate system in the target interface and searching the corresponding target labeling area according to the first coordinate point set of the first input position information, the accuracy of searching the target labeling area can be improved, and the accuracy of the finally obtained first selection frame is further improved.

Specifically, after the target interface is configured with the coordinate system, a reference line is marked on a marking area in the target interface. Because the labeling area is obtained by converting the rectangular color blocks, the labeling area is labeled with a first reference line and a second reference line. The first datum line is an extension line of a transverse center line of each marking area, and the second datum line is an extension line of a vertical center line of each marking area. And acquiring a first distance between each first reference line and the abscissa of the picture coordinate system and a second distance between each second reference line and the ordinate of the picture coordinate system, and determining the coordinates of each marking area according to the lengths of the four sides of the marking area, the first distances and the second distances.

And generating and displaying a first selection frame according to the third coordinate point set.
Coordinate points of the second coordinate point set corresponding to the target labeling area are adjusted through the preset coordinate adjustment value to obtain a third coordinate point set, so that the first selection frame is generated and displayed, the coincidence degree of the first selection frame and the character information is guaranteed, and meanwhile the character information is prevented from being shielded due to the fact that the first selection frame and the character information are overlapped.
In the step of calculating the third coordinate point set according to the second coordinate point set, it is required to ensure that the generated first frame is located outside the target labeling area.
As shown in fig. 9, the step of screening the second coordinate point set in the coordinate set according to the first coordinate point set specifically includes:
and step 504, determining a target coordinate in the coordinate set according to the magnitude relation between the first coordinate point set and the distance value of each coordinate in the coordinate set.

The specific way to determine the target coordinates is as follows:
as shown in fig. 10, the distance between the upper edge of the four edges of the rectangular coverage area and the abscissa of the coordinate system is obtained, and the distance between the first reference line of each labeling area and the abscissa of the coordinate system is obtained, so as to determine the distance value between the upper edge and each coordinate.
And then obtaining the distance from the lower edge of the rectangular coverage area to the abscissa of the coordinate system, and obtaining the distance from the first reference line of each marking area to the abscissa of the coordinate system, thereby determining the distance value from the lower edge to each coordinate.
As shown in fig. 11, the distance from the left side of the rectangular coverage area to the ordinate of the coordinate system is obtained, and the distance from the second reference line of each labeling area to the ordinate of the coordinate system is obtained, so as to determine the distance value from the left side of the second picture selection frame to each coordinate.
And finally, acquiring the distance from the right side of the second picture selection frame to the vertical coordinate of the coordinate system, and acquiring the distance from the second reference line of each marking area to the vertical coordinate of the coordinate system, thereby determining the distance value from the right side to each coordinate.
The target coordinate can be determined through the method, wherein the target coordinate comprises coordinate values of four sides, and the target labeling area can be found based on the coordinate values of the four sides.
The first datum line is an extension line of a transverse center line of each marking area, and the second datum line is an extension line of a vertical center line of each marking area.
It is to be understood that "up, down, left, and right" in the above embodiments are based on the coordinate systems in fig. 10 and 11.
