[0035] According to one aspect of an embodiment of the present application, a method for processing an image target is provided. Optionally, in this embodiment, the method for processing an image target can be applied to Figure 1 In the hardware environment composed of the image annotation device 102 and the server 104 shown in FIG. Figure 1 As shown, the server 104 is connected to the image annotation device 102 via a network, and can be used to provide services (such as application services, etc.) for the terminal or a client installed on the terminal. A database can be set on the server or independently of the server to provide data storage services for the server 104.

[0036] The network may include but is not limited to at least one of the following: a wired network, a wireless network. The wired network may include but is not limited to at least one of the following: a wide area network, a metropolitan area network, a local area network, and the wireless network may include but is not limited to at least one of the following: WIFI (Wireless Fidelity), Bluetooth. The image annotation device 102 may not be limited to a PC, a mobile phone, a tablet computer, etc.

[0037] The image target processing method of the embodiment of the present application may be executed by the server 104, or by the image annotation device 102, or by both the server 104 and the image annotation device 102. The image annotation device 102 may execute the image target processing method of the embodiment of the present application, or the client installed thereon.

[0038] Taking the image tagging device 102 as an example, the image target processing method in this embodiment is executed. Figure 2 is a flow chart of an optional method for processing an image target according to an embodiment of the present application, such as Figure 2 As shown, the process of the method may include the following steps:

[0039] Step S202: displaying a first image to be labeled on a target display interface, wherein the first image to be labeled includes a target object to be labeled.

[0040] The method for processing image targets in this embodiment can be applied to a scenario where annotated targets in an image to be annotated are annotated by an image annotation device, and the target object is annotated by performing corresponding operations on the image annotation device. A target application for image annotation can be run on the image annotation device, and a first image to be annotated can be displayed on the target display interface of the target application, and the first image to be annotated can contain at least one target object to be annotated (i.e., annotated target). The target object can be a moving object, such as a vehicle, a pedestrian, etc. In addition, a drawing tool for assisting in drawing a rotating box can be displayed on the target display interface.

[0041] Step S204, in response to the detected first drawing operation, draw a first side of a rotation annotation box of the target object on the target display interface, wherein the angle of the first side is a target angle, and the first drawing operation is used to indicate the positions of a first vertex and a second vertex corresponding to the first side.

[0042] The marking target can be marked by drawing a rotated rectangle, and the rotated rectangle is a rectangle that allows a certain rotation angle. In the related art, when drawing a rotated rectangle for the marking target, a complete rectangle is usually drawn first according to the upper left vertex and the lower right vertex, and then the drawn rectangle is rotated according to the shape of the marking target (the area occupied), etc., and it can be matched with the marking target after being rotated by a certain angle to obtain the rotated marking frame of the marking target. For the above-mentioned method of drawing the rotating marking frame, the operation process is cumbersome, and it is easy to make mistakes during adaptation (it is easy to rotate too large or too small to cause mismatch with the marking target), and the efficiency is low.

[0043] In order to solve the above problem, in this embodiment, an edge of an arbitrary angle can be drawn first, and then a third vertex can be drawn on the vertical line of the edge to generate a rotated annotation box (a rotated rectangle). The user can view the first image to be annotated and determine the annotation target contained therein, that is, the target object. Optionally, an object range identifier of at least one candidate object identified from the first image to be annotated can be displayed on the first image to be annotated. That is, the first image to be annotated can be preprocessed by an image annotation device or other device, and multiple candidate objects and the object range of each candidate object can be identified from the first image to be annotated, which can include the target object and other misidentified objects. According to the object range of each candidate object, the image annotation device can display the object range identifier of each candidate object on the target display interface.

[0044] The user may perform a first drawing operation on the target display interface, and the first drawing operation is used to trigger drawing of a first side of a rotation annotation box of the target object. The above-mentioned first drawing operation may be an operation performed by the user directly on the image to be annotated displayed on the target display page, or an operation performed on a drawing tool on the display screen that assists in drawing a rotation box. By performing the first drawing operation, the user may indicate the position of the first side of the rotation annotation box of the target object on the target display page, for example, the position of the first vertex and the second vertex may be indicated, and the first side may be drawn according to the positions of the first vertex and the second vertex.

[0045] For example, the first drawing operation performed by the user may be to perform operations such as clicking, double-clicking, sliding, etc. on the image to be annotated displayed on the target display page to indicate the positions of the first vertex and the second vertex. For another example, the user may perform operations on input and output components such as a mouse and a keyboard connected to the image annotation device to indicate the positions of the first vertex and the second vertex, which is not limited in this embodiment.

[0046] The image annotation device can detect a first drawing operation, and in response to the first drawing operation, draw an edge of the annotation box formed by connecting the first vertex and the second vertex on the target display interface, that is, the first edge. The thickness, color, etc. of the first edge can adopt default values ​​and can be adjusted based on the user's configuration. The first edge can be adjustable or fixed. The angle of the drawn first edge is the target angle, which can be the angle formed by the first edge and the horizontal line.

[0047] Step S206 , in response to the detected second drawing operation, determining a third vertex of the rotated annotation box of the target object, wherein the second drawing operation is used to indicate a position of the third vertex in a target direction starting from the second vertex and perpendicular to the first side.

[0048] After drawing the first edge, the user may perform a second drawing operation on the image annotation device. The second drawing operation may be an operation to indicate the position of the third vertex. During the second drawing operation, a line may be displayed on the target display interface starting from the second vertex and perpendicular to the first edge as a reference edge, that is, the edge where the third vertex to be drawn is required to be located. The user may select a suitable position on the reference edge, and the selected position may be marked as the third vertex.

[0049] Similar to or similar to the above embodiment, the image annotation device can detect the second drawing operation, obtain the position of the third vertex, and determine the position of the third vertex as the third vertex of the rotated annotation box to be drawn. Here, the rotated annotation box refers to an annotation box that is allowed to have a certain angle compared to the horizontal line or other reference line.

[0050] Step S208: Draw a rotation annotation box of the target object on the target display interface according to the first side and the third vertex to obtain a target rotation annotation box.

[0051] According to the characteristics of the rectangle, after drawing the third vertex, that is, after determining a side and a vertex (or three vertices) of the rectangle, a rectangle can be directly determined. The way to determine the rectangle can be: determine the fourth vertex, and then determine a rectangle according to the four vertices, or: determine the four sides, and the closed area surrounded by the four sides is the required rectangle. Here, the way to determine the fourth vertex can be: use the line connecting the first vertex and the third vertex as the axis of symmetry, and determine the point symmetrical to the center of the second vertex as the fourth vertex.

[0052] After a rectangle is determined, the determined rectangle is the rotation annotation box of the target object, that is, the target rotation annotation box. The image annotation device can draw a target rotation annotation box on the target display interface. After drawing the target rotation annotation box, the user can determine whether the target rotation annotation box can annotate the target object. For example, it can be determined whether the target object can be placed in the target rotation annotation box. If so, it can be determined that the annotation of the target object in the first image to be annotated is completed. Otherwise, the rotation annotation box of the target object can be redrawn in the same or similar manner as in the aforementioned embodiment, or the target rotation annotation box can be adjusted by operations such as translation until it is determined that the target rotation annotation box can annotate the target object.

[0053] Optionally, after obtaining the target rotation annotation frame, the user can annotate other annotation targets that need to be annotated in the first image to be annotated, or jump to the next image to be annotated in the first image to be annotated and annotate the annotation targets in the next image to be annotated.

[0054] Through the above steps S202 to S208, a first image to be annotated is displayed on a target display interface, wherein the first image to be annotated includes a target object to be annotated; in response to a detected first drawing operation, a first side of a rotational annotation box of the target object is drawn on the target display interface, wherein the angle of the first side is a target angle, and the first drawing operation is used to indicate the positions of a first vertex and a second vertex corresponding to the first side; in response to a detected second drawing operation, a third vertex of the rotational annotation box of the target object is determined, wherein the second drawing operation is used to indicate the position of the third vertex in a target direction starting from the second vertex and perpendicular to the first side; a rotational annotation box of the target object is drawn on the target display interface according to the first side and the third vertex, to obtain a target rotational annotation box, which solves the problem that the image object annotation method in the related art needs to adjust the rectangle multiple times, resulting in a cumbersome object annotation process, simplifies the object annotation process, and improves the efficiency of object annotation.

[0055] In an exemplary embodiment, in response to a detected first drawing operation, drawing a first side of a rotation annotation box of a target object on a target display interface includes:

[0056] S11, in response to the detected first sub-drawing operation, drawing a first vertex on the target display interface, wherein the first sub-drawing operation is used to indicate the position of the first vertex;

[0057] S12, in response to the detected second sub-drawing operation, drawing a first edge on the target display interface according to the target angle, wherein the second sub-drawing operation is used to indicate the position of the second vertex.

[0058] In this embodiment, the first drawing operation may include a first sub-drawing operation and a second sub-drawing operation, respectively for drawing the first vertex and the second vertex. In response to detecting the first sub-drawing operation and the second sub-drawing operation, the image annotation device may draw a first edge on the target display interface, and the drawn first edge may have a target angle.

[0059] Optionally, when the user performs the first sub-drawing operation and the second sub-drawing operation, the image annotation device will issue a prompt to the user (for example, a voice prompt, a pop-up prompt, etc.) to remind the user whether to use the currently drawn point as the first vertex and the second vertex.

[0060] According to this embodiment, the first edge is drawn through different drawing operations, which can improve the flexibility of the first edge drawing and improve the efficiency of object annotation.

[0061] In an exemplary embodiment, before drawing the first edge on the target display interface according to the target angle, the method further includes:

[0062] S21, displaying a first moving edge with a first vertex as a starting point on a target display interface, wherein an end point position of the first moving edge moves along with movement of an input position on the target display interface.

[0063] In this embodiment, due to the uncertainty of the target object (for example, the target object has different shapes), in the process of drawing the first edge, the spacing between the first vertex and the second vertex is set unreasonably, or the angle of the drawn first edge is too small to completely mark the target object, resulting in failure to draw the rotated rectangle. Therefore, when drawing the first edge, the first vertex can be drawn on the target display interface in response to the detected first sub-drawing operation. Then, a moving edge with the first vertex as the starting point is used to assist in determining the drawing position of the second vertex.

[0064] After drawing the first vertex, a first moving edge with the first vertex as the starting point can be displayed on the target display interface. The end point of the first moving edge moves along with the movement of the input position on the target display interface. By adjusting the end point of the first moving point, a suitable angle (i.e., the target angle) can be selected. For example, at the target angle, the first edge will not pass through the target object and has a reasonable distance from the target object. For example, the first edge cannot touch the target object. After finding a suitable position, the user can perform the drawing operation of the second vertex. The specific operation process can refer to the aforementioned embodiment and will not be repeated here.

[0065] Through this embodiment, after a vertex is determined, a moving edge is displayed with the vertex as the starting point and the end point position changes with the input position, which can facilitate finding a suitable drawing angle and improve the efficiency of object annotation.

[0066] In an exemplary embodiment, in the process of displaying the first moving edge starting from the first vertex on the target display interface, the method further includes:

[0067] S31, displaying a first auxiliary edge on the target display interface, which has the end point of the first moving edge as a starting point and is perpendicular to the first moving edge.

[0068] In this embodiment, in order to improve the efficiency of drawing the rotated rectangle, a first auxiliary edge with the end point of the first moving edge (for example, the input position of the target display page) as the starting point and a direction perpendicular to the first moving edge can be displayed at the same time as the first moving edge is displayed. The first auxiliary edge can be a ray shape or a straight line shape, which is not limited in this embodiment.

[0069] Since the annotation target is displayed in two dimensions, if the rectangle (which can be a semi-enclosed structure) formed by the drawn points is not intuitively marked, the rotation matrix drawn based on the information seen will have a poor match with the target object. By adding auxiliary lines, the position of the rotation rectangle to be drawn can be intuitively displayed, improving the efficiency of drawing the rotation inverse matrix.

[0070] Through this embodiment, after a moving edge is displayed, an auxiliary edge corresponding to the moving edge is displayed to assist in object labeling, thereby improving the efficiency of object labeling.

[0071] In an exemplary embodiment, after drawing a first side of a rotation annotation box of the target object on the target display interface, the method further includes:

[0072] S41, displaying a second moving edge with a second vertex as a starting point and a direction perpendicular to the first edge on the target display interface, wherein the end position of the second moving edge moves following the input position on the target display interface.

[0073] In this embodiment, after determining the second vertex and drawing the first side, the user can directly specify the position of the drawn third vertex. In order to ensure the accuracy of object annotation, after drawing the first side, a second moving side can be displayed. The second moving side can be an side starting from the second vertex and perpendicular to the first side. The end position of the second moving side can move with the input position on the target display interface. By adjusting the input position, the length of the second east side can be adjusted to assist in determining the annotation of the target object.

[0074] Through this embodiment, after drawing the first edge, a moving edge is displayed with a vertex of the first edge as the starting point and in a direction perpendicular to the first edge, which can assist in drawing a rotating rectangular box and improve the efficiency of object annotation.

[0075] In an exemplary embodiment, in the process of displaying a second moving edge starting from the second vertex and perpendicular to the first edge on the target display interface, the method further includes:

[0076] S51, displaying a second auxiliary edge on the target display interface, with the end point of the second moving edge as the starting point and the direction perpendicular to the second moving edge.

[0077] In this embodiment, in order to improve the efficiency of drawing the rotated rectangle, a second auxiliary edge with the end point of the second moving edge (for example, the input position of the target display page) as the starting point and a direction perpendicular to the second moving edge can be displayed at the same time as the second moving edge is displayed. The second auxiliary edge can be a ray shape or a straight line shape, which is not limited in this embodiment.

[0078] Since the annotation target is displayed in two dimensions, if the rectangle (which can be a semi-enclosed structure) formed by the drawn points is not intuitively marked, the rotation matrix drawn based on the information seen will have a poor match with the target object. By adding auxiliary lines, the position of the rotation rectangle to be drawn can be intuitively displayed, improving the efficiency of drawing the rotation inverse matrix.

[0079] Through this embodiment, after a moving edge is displayed, an auxiliary edge corresponding to the moving edge is displayed to assist in object labeling, thereby improving the efficiency of object labeling.

[0080] In an exemplary embodiment, drawing a rotation annotation box of the target object on the target display interface according to the first side and the third vertex to obtain the target rotation annotation box includes:

[0081] S61, drawing a second side of a rotation annotation box of the target object between the second vertex and the third vertex on the target display interface;

[0082] S62, determining a fourth vertex of the rotated annotation box of the target object according to the first vertex, the second vertex and the third vertex;

[0083] S63, drawing a third side of the rotated annotation box of the target object between the third vertex and the fourth vertex, and drawing a fourth side of the rotated annotation box of the target object between the fourth vertex and the first vertex, to obtain a target rotated annotation box.

[0084] In this embodiment, after determining the first side and the third vertex, a unique rotated rectangle can be directly determined. For example, the second side of the rotated rectangle can be drawn between the second vertex and the third vertex; then, the fourth vertex of the rotated annotation box of the target object is determined based on the first vertex, the second vertex, and the third vertex. In addition to being obtained by the diagonal line of the rectangle in the aforementioned embodiment, the fourth vertex can also be obtained by drawing a perpendicular line from the first vertex and the third vertex adjacent to the fourth vertex in the direction matching the first side and the second side. Since the four corners of the rectangle are right angles, the intersection of the perpendicular line of the first vertex and the third vertex is the fourth vertex.

[0085] After obtaining the position information of the fourth vertex, the third side of the rotation annotation box of the target object can be drawn between the third vertex and the fourth vertex, and the fourth side of the rotation annotation box of the target object can be drawn between the fourth vertex and the first vertex to obtain the target rotation annotation box.

[0086] Through this embodiment, the fourth vertex is determined according to the vertices at known positions through the geometric relationship of the rectangle, and then the rotated annotation frame of the annotation target can be obtained, thereby improving the efficiency and convenience of object annotation.

[0087] In an exemplary embodiment, after drawing a rotation annotation box of the target object on the target display interface according to the first side and the third vertex and obtaining the target rotation annotation box, the method further includes:

[0088] S71, displaying a second image to be annotated and a target rotation annotation frame on a target display interface, wherein the second image to be annotated includes a target object to be annotated, and the second image to be annotated is an image adjacent to the first image to be annotated in the video to be annotated;

[0089] S72: In response to the detected association operation, determine the target rotated annotation box as the rotated annotation box of the target object in the second image to be annotated.

[0090] In this embodiment, after obtaining the target rotation annotation frame, the user can continue to annotate the next annotation target in the first image to be annotated. Alternatively, the first image to be annotated can be a frame image in the video to be annotated, and the image annotation device can display the next frame image of the first image to be annotated in the video to be annotated on the target display interface, that is, the second image to be annotated.

[0091] When annotating the target in the second image to be annotated, the same or similar method as in the above embodiment can be used for annotation. Optionally, in this embodiment, since there is a certain correlation between the objects contained in adjacent video images in the video to be annotated, the target rotation annotation frame of the first image to be annotated can be displayed together with the second image to be annotated on the target display interface.

[0092] The user can determine whether the target rotated annotation box marks the position of the target object in the second image to be annotated. If so, an association operation can be performed on the target rotated annotation box and the target object to determine the target rotated annotation box as the rotated annotation box of the target object in the second image to be annotated, thereby eliminating the need to draw the annotation box of the target object. Otherwise, the displayed target rotated annotation box can be removed so that the user can re-annotate the target object.

[0093] Through this embodiment, when annotating continuous images, the annotation result of the previous frame of image is combined to assist in object annotation of the next frame, which can reduce the time consumption of annotation and improve the efficiency of object annotation.

[0094] The following is an explanation of the processing method of the image target in the embodiment of the present application in conjunction with an optional example. For ease of understanding, in this optional example, a rotation matrix with a certain angle is directly drawn on the canvas without indicating the association with the labeled target, which can be applied to a variety of application scenarios. In this optional example, the first fixed point is fixed point A, the second fixed point is B, the first moving point is B', the third fixed point is fixed point C, the second moving point is C', and the fourth fixed point is fixed point D.

[0095] This optional example provides a solution for drawing a rotated rectangle, which uses a method without auxiliary lines to draw a rotated rectangle. Figure 3 and Figure 4 As shown, the process of the method for processing an image target in this optional example may include the following steps:

[0096] Step 1, draw the fixed point A;

[0097] Step 2, draw the second moving point B and moving side AB';

[0098] Step 3. After finding the right position, draw the fixed point B, and continue to draw the third moving point C, as well as the moving side BC' (the moving side BC' should always remain perpendicular to the fixed side AB);

[0099] Step 4. After finding the appropriate position, draw the fixed point C. At this time, the rotated rectangle has three fixed points, namely A, B, and C. The position of the fourth fixed point D is also determined, and the rotated rectangle path is closed.

[0100] This optional example also provides a solution for drawing a rotated rectangle, which uses auxiliary lines to draw the rotated rectangle. Figure 5 As shown, the process of the method for processing an image target in this optional example may include the following steps:

[0101] Step 1, first draw a fixed point A on the canvas;

[0102] Step 2, draw the second moving point B and the moving side AB'. At this time, the auxiliary line is B'C' (the auxiliary line B'C' should always be perpendicular to the moving side AB'). The position of the point B to be drawn can be adjusted according to the position of the auxiliary line B'C' and the moving point C'.

[0103] Step 3. After finding the right position, draw the fixed point B, and continue to draw the third moving point C, and the moving side BC' (the moving side BC' should always remain perpendicular to the fixed side AB). At this time, the auxiliary line is C'D' (the auxiliary line C'D' should always remain perpendicular to the moving side BC'). The position of the point D to be drawn can be adjusted according to the position of the auxiliary line C'D' and the moving point D'.

[0104] Step 4. After finding the appropriate position, draw the fixed point C. At this time, the rotated rectangle has three fixed points, namely A, B, and C. The position of the fourth fixed point D is also determined, and the rotated rectangle path is closed.

[0105] Through this optional example, by using auxiliary lines and no auxiliary lines to assist in drawing a rotated rectangle, the applicability of rotating rectangle drawing can be improved.
