After the movement track is formed, a track graph is formed based on the movement track, and the track graph is an overall graph formed on the basis of the movement track and can be a regular or irregular graph, such as a circle, a rectangle, a pentagon, an arbitrary polygon and the like. The track graph provided by the disclosure is a closed graph, and if the graph formed based on the motion track is a non-closed graph, the non-closed graph needs to be complemented to obtain a closed track graph.

Moreover, the area covered by the intercepting frame only comprises the target object, so that the accurate positioning and intercepting of the target object are realized, a user does not need to accurately draw the boundary of the target object, and the operation complexity of the user is reduced.

For example: the target objects are characters distributed at two rows of end points, only the characters at two ends can be intercepted by utilizing the user-defined intercepting frame, the purpose of intercepting the target characters at one time is realized, repeated intercepting is not needed, and the operation complexity of intercepting the target characters is reduced.

In order to make clearer the intercepting scheme of the target object and the technical effect thereof provided by the present disclosure, specific embodiments thereof are described in detail with a plurality of examples.

In one embodiment, the step of analyzing the motion trajectory formed by arranging the target instructions along the time axis in step S101 includes the following sub-steps:

a1, receiving the contact area of the target instruction on the touch interface, and determining the drawing parameters of the motion trail according to the contact area;

and A2, drawing a corresponding motion track according to the drawing parameters.

Input data received in the preset area of the touch interface comprises a contact position, a contact area when the touch mode is contacted with the touch interface and the like, wherein the touch mode comprises a finger, a touch pen and the like, the contact areas corresponding to different touch modes are different, the contact area is related to the fine degree of a motion track, the contact area of the finger and a touch screen is larger, a drawing line which can be set to be the motion track is thicker, the corresponding contact area when the touch pen is used for drawing is smaller, the corresponding drawing line can be set to be thinner, the motion track precision is higher, therefore, the drawing parameters of the motion track are determined according to the contact area of the input data, when the motion track is a line, the corresponding drawing parameters comprise: line thickness, line colour etc. can set up that the contact area is big more, and the line is thick more, and the line colour is bright-colored more, and the striking degree of motion trail is high more, and the contact area is little more corresponding the line for the motion trail of drawing is more meticulous.

The present disclosure also provides other embodiments for determining the drawing parameters of the motion trajectory, such as determining the drawing parameters according to the area of the target object, and such as setting the larger the area of the target object, the finer the motion trajectory. The drawing parameters of the motion trajectory may also be determined according to the attribute parameters of the boundary line of the target object, such as setting the line thickness of the motion trajectory to be the same as the boundary line of the target object.

According to the embodiment, the drawing parameters of the motion trail are determined according to the area of the contact point on the touch interface, so that the motion trail drawn according to the drawing parameters includes the boundary line of the target object as much as possible, the fault tolerance rate is increased, the motion trail can be adjusted into the line adaptive to the motion trail according to the area of the contact point, and the visual effect is improved.

In one embodiment, the step of adjusting the trajectory graph by using the boundary line of the target object in step S103 may be performed as follows, and the flowchart is shown in fig. 2, and includes the following sub-steps:

s201, calling a preset boundary algorithm to extract boundary data of the target object, and determining a boundary line of the target object;

s202, when the motion trail intersects with the boundary line of the target object, the motion trail between the intersection points is adjusted to be outside the boundary line, so that the area covered by the trail graph covers the target object.

The preset boundary algorithm may be a boundary tracking algorithm, and for a target object with a closed boundary line, the process of obtaining the boundary line of the target object by using the boundary algorithm is as follows: firstly, determining a starting point of a boundary line of a target object; determining a corresponding boundary judgment criterion and a corresponding search criterion, wherein the judgment criterion is used for judging whether one point is a boundary point, and the search criterion is used for guiding how to search the next boundary point; determining the end condition of the search, determining the end point of the boundary line by using the end condition, and sequentially connecting the determined boundary points from the start point of the boundary line to the end point to form the boundary line of the target object.

When the motion trajectory intersects with the target object, the number and positions of the intersections are not limited, fig. 3 is a schematic diagram illustrating that the motion trajectory provided by an embodiment intersects with the boundary line of the target object, and 2 intersections of the motion trajectory and the boundary line of the target object are a and b, respectively.

In the embodiment, the trajectory graph is adjusted to the shape completely containing the boundary line of the target object under the condition that the intersection point exists between the motion trajectory and the boundary line of the target object, so that the trajectory graph is corrected, and the target object can be conveniently and completely intercepted based on the corrected trajectory graph.

The present disclosure also provides another way to achieve the purpose of adjusting the motion trajectory by using the boundary line of the target object, and a schematic flow chart thereof is shown in fig. 2, and includes:

s203, acquiring a target object with a complete boundary line in an area covered by the track graph;

s204, adjusting the motion track of the track image to be overlapped with the boundary line of the target object.

The scheme provided by the embodiment is that when the track graph is not crossed with the boundary line of the target object and the target object is completely covered in the area covered by the track graph, the track graph is reduced to be overlapped with the boundary line of the target object, so that the purpose of accurate interception is achieved.

The scheme provided by this embodiment may be performed after step S202, that is, if the motion trajectory intersects the boundary line of the target object, the motion trajectory between the intersection points is adjusted to be outside the boundary line of the target object through the schemes provided in S201 to S202, and then the motion trajectory is adjusted to be overlapped with the boundary line of the target object through the schemes provided in S203 to S204, so as to achieve accurate positioning of the target object, so as to perform accurate interception on the target object subsequently.

When the area covered by the track graph comprises at least two target objects with complete boundary lines, the track graph is adjusted to cover the target object cluster or the track graph only covers the target objects, different target objects are connected through straight lines, and the area ratio of the target objects in the intercepting frame is improved.

In the case that the motion trajectory forms a non-closed figure, that is, there is a discontinuity in the motion trajectory, and the motion trajectory includes a known motion trajectory segment and a discontinuity, in this case, the step of forming the trajectory figure based on the motion trajectory may be performed in the following manner, and a flowchart thereof is shown in fig. 4, and includes:

s401, completing the discontinuous points based on a preset completing mode to form a post-repairing motion track section;

s402, the known motion track section and the rear complement motion track section are spliced to form a closed track graph.

When the motion trail has the break points, a preset completion mode is called to complete the motion trail sections between the break points, wherein the completion mode can be preset in various ways, the corresponding completion mode is determined according to the characteristics of the break points so as to improve the completion effect, the completed motion trail sections and the current motion trail sections are spliced after the motion trail between the break points is completed by the completion mode, and if the motion trail sections obtained by the completion mode have multiple sections, the splicing operation is sequentially executed, and finally a closed trail graph is formed.

Specifically, if there are a plurality of discontinuities, each discontinuity is numbered in sequence, and the difference between the distance between the first discontinuity and the last discontinuity and the distance between any two other adjacent discontinuities is within a preset error range, that is, the first discontinuity and the last discontinuity form an adjacent discontinuity, and a closed graph can be formed after the adjacent discontinuities are connected, so that the closed graph is a track graph. If the difference between the distance between the first discontinuity point and the last discontinuity point and the distance between any two other adjacent discontinuity points exceeds a preset error range, a closed graph cannot be formed after the adjacent discontinuity points are connected, and the discontinuity points need to be supplemented again to form a closed track graph.

The following embodiments of the present disclosure provide several compensation formulas for compensating a motion trajectory between discontinuities, which are as follows:

in one embodiment, the step of completing the discontinuities based on a predetermined completion method to form post-completion motion track segments includes:

b1, acquiring the known curvature of the known motion track segment, and determining the unknown curvature of the post-compensation motion track segment according to the known curvature;

b2, forming a post-compensation motion trajectory segment between the discontinuities according to the unknown curvature.

If the continuous motion track segment has multiple curvatures, determining the curvature corresponding to the post-compensation motion track segment based on the multiple curvatures, for example, taking the mean value of all known curvatures as the curvature corresponding to the motion track segment between the discontinuities, or determining the curvature corresponding to the post-compensation motion track segment according to the trend of the multiple curvatures. Furthermore, the post-compensation motion track section can be divided into a plurality of sub post-compensation motion track sections, the curvature of each sub post-compensation motion track section is determined in sequence according to the trend of the known curvature, the unknown curvature of the post-compensation motion track section can be obtained more accurately, and a more accurate track graph is obtained based on the unknown curvature.

The scheme provided by the disclosure is suitable for the condition that the continuous motion track section has obvious curvature, the unknown curvature of the post-compensation motion track section between the break points is determined based on the known curvature of the continuous motion track section, compared with the mode of linearly compensating and connecting the break points, the motion track compensated according to the unknown curvature is more consistent with the real intention of a user, and the track graph obtained based on the post-compensation motion track section is more accurate.

The present disclosure provides another embodiment of the method for obtaining a track graph, specifically, the step of completing the break points based on a preset completing method to form a post-repairing motion track segment, including:

and calling an interpolation algorithm to perform interpolation processing on the discontinuous points to form a post-compensation motion track section between the discontinuous points.

And constructing a post-compensation motion track section between the break points by utilizing an interpolation algorithm based on the known motion track section, wherein the constructed post-compensation motion track section can reflect the rule of the known motion track section, and the post-compensation motion track section is determined based on the rule, so that the accuracy of the track graph is improved.

c1, comparing the known motion track segment with the pre-stored motion track data;

and C2, determining the track section corresponding to the motion track data with the highest matching degree as the rear compensation motion track section between the break points.

Wherein, the pre-stored motion trail data comprises: the pre-stored motion trail data, historical motion trail data and the like of the user can be combined with the pre-stored motion trail data and the adoption rate of each motion trail data to serve as a standard for judging the matching degree.

The scheme provided by the embodiment utilizes the pre-stored motion trail to complement the motion trail, and reduces the complexity of the complementing step and the complementing mode while ensuring the accuracy of the motion trail section.
