It should be noted that the first mark frame in this embodiment may also be a mark frame that is not displayed first, for example, the mark frame that is displayed second or last may be selected as the first mark frame according to the display order of the mark frames; the first mark frame may also be selected in other manners, such as the first mark frame may be determined based on the cursor position, etc., which is not particularly limited in the practice of the invention.
In addition, the user can modify the target annotation vertex needing to be annotated currently by submitting an annotation switching instruction. Further, after the cursor is displayed in the mark frame corresponding to the target mark vertex, the embodiment of the present invention may further include: receiving a labeling vertex switching instruction; and moving the cursor to a second mark frame of the three-dimensional graph according to the mark vertex switching instruction, and replacing the target mark vertex with a vertex corresponding to the second mark frame. The annotation vertex switching instruction may be used to switch the mark frame where the cursor is located, so as to modify the target annotation vertex that needs to be annotated currently, and the annotation vertex switching instruction may be triggered by a user operation, such as may be generated based on a keyboard operation or a mouse operation or a touch operation submitted by the user. For example, the user operation may be an operation of clicking a Tab key of a keyboard, which is not limited by this example.
In this embodiment, a user may submit a labeling trigger instruction to the interactive intelligent tablet by clicking a button or a keyboard shortcut key displayed on the intelligent interactive device, so that the intelligent interactive device enters a vertex labeling state. For example, a user may trigger an instruction to the label by clicking a "vertex label" button displayed by the intelligent interactive device to trigger the intelligent interactive device to generate an entry into a vertex label state. Of course, the user may also trigger the intelligent interaction device to enter the vertex labeling state in other ways, for example, the user may quickly enter the vertex labeling state by clicking a preset shortcut key such as a "Ctrl + M" key in the keyboard, which is not limited in this example.
When the vertex labeling state is entered, the mark frames may be automatically displayed at the labeling positions of the vertices of the solid geometry, as shown in fig. 4, and the input cursor may be positioned in the first mark frame, that is, the first displayed mark frame may be determined as the mark frame corresponding to the target labeling vertex, and the cursor may be displayed in the mark frame corresponding to the target labeling vertex.
In this embodiment, the user may input a label vertex switching instruction to the intelligent interaction device to trigger the intelligent interaction device to move the cursor to the mark frame of another vertex according to the label vertex switching instruction, so as to switch the target label vertex to another vertex, that is, move the cursor to the second mark frame of the stereoscopic graph and replace the target label vertex with a vertex corresponding to the second mark frame. For example, the user may submit a label vertex switch instruction to the intelligent interactive device by pressing a "TAB" key, so as to switch the mark box where the input cursor is located, as shown in fig. 4, and move the cursor from the first mark box to the second mark box, so as to switch the target label vertex to another vertex.
In an optional embodiment of the present invention, when the labeling vertex marking state is entered, the marking frame of the vertex of the stereoscopic graphic may not be automatically displayed, but the marking frame corresponding to a certain vertex is displayed when the mouse moves to a vicinity of the vertex, so as to determine the vertex as the target labeling vertex, and the input cursor may be positioned in the marking frame corresponding to the target labeling vertex, so as to determine the marking frame corresponding to the target labeling vertex as the first marking frame, so that the user may input information in the first marking frame to label the target labeling vertex. Optionally, the determining the target labeling vertex of the stereoscopic image includes: after receiving a marking trigger instruction, monitoring the position of a cursor; and when the distance between the cursor position and any vertex position in the three-dimensional graph is smaller than a preset distance, determining the vertex corresponding to the vertex position as a target labeling vertex of the three-dimensional graph.
In a specific implementation, after receiving the vertex triggering instruction, the embodiment of the present invention may enter the vertex labeling state according to the labeling triggering instruction, so as to detect the position of the monitoring cursor in the vertex labeling state. The cursor position may refer to a display position of an input cursor, and the cursor position may be determined according to a touch operation or a mouse operation, which is not limited in this embodiment. The monitored cursor position may then be compared to the positions of the vertices of the currently displayed stereoscopic graphic to determine the spacing between the cursor position and the positions of the vertices of the stereoscopic graphic. If the distance between the cursor position and a vertex position in the three-dimensional graph is smaller than a preset distance, the vertex corresponding to the vertex position can be determined as a target labeling vertex, then at least two ridge lines associated with the target labeling vertex can be determined, and the labeling position of the target labeling vertex can be determined according to included angles of the ridge lines between the ridge lines, so that a labeling frame corresponding to the target labeling vertex can be displayed according to the labeling position of the target labeling vertex, meanwhile, the cursor can be positioned into the labeling frame corresponding to the target labeling vertex and displayed, a user is prompted to label the target labeling vertex by inputting information in the labeling frame, the user does not need to manually drag and drop a text frame for the vertex to be labeled as the labeling frame, the user operation is simplified, and the vertex labeling efficiency is improved.
Further, before displaying the cursor in the mark frame corresponding to the vertex of the target label, the embodiment may further include: determining ridge projection information corresponding to the target labeling vertex, wherein the ridge projection information is used for determining at least two included angles of ridges of the target labeling vertex; selecting a target ridge included angle from the at least two ridge included angles; determining angular bisector information corresponding to the target ridge included angle, wherein the angular bisector information is used for determining a marking position on an angular bisector of the target ridge included angle; and displaying the marking frame, wherein the marking frame is displayed according to the marking position.
Specifically, when a target labeling vertex is determined, ridge projection information corresponding to the target labeling vertex can be determined according to coordinate information corresponding to other vertices adjacent to the target labeling vertex, then one or more ridge included angles of the target labeling vertex can be determined based on the ridge projection information corresponding to the target labeling vertex, a target ridge included angle with a largest included angle can be selected according to the determined ridge included angles, a labeling position can be determined on a bisector of the target ridge included angle according to the bisector information of the target ridge included angle, and therefore a labeling frame corresponding to the target labeling vertex can be displayed at the labeling position.
As an example of the present invention, when the interactive smart tablet enters the vertex marking state, the marking frame corresponding to the vertex of the stereoscopic graphic may not be automatically displayed, and when the mouse moves to a position near a certain vertex, the vertex is highlighted, and a marking frame may be displayed at the marked position of the vertex, as shown in fig. 5. At this time, if the user clicks the left mouse button, a mark box is added to the vertex. After adding the "mark box", the input cursor can be automatically positioned inside the mark box, so that the user can input the identification letter in the mark box, namely, the input information marks the target mark vertex. When the user clicks the mouse outside the marking frame, the interactive intelligent panel can confirm that the user finishes inputting, and input information of the user is associated with the target marking vertex so as to finish marking the target marking vertex and quit the marking state of the target marking vertex. When the user moves the mouse near other vertices, the interactive smart tablet may repeatedly perform the above operations, i.e., may label the other vertices.
Furthermore, in the embodiment of the present invention, when the three-dimensional graph changes, as shown in fig. 6, when the three-dimensional graph rotates, the display position of the vertex corresponding to the mark frame can be automatically adjusted according to the change of the three-dimensional graph, that is, the label position of the vertex can be automatically adjusted, which avoids the trouble of manually adjusting the position of the mark frame after the three-dimensional graph changes by a user, and further simplifies the user operation. Optionally, this embodiment may further include: when the change of the three-dimensional graph is detected, hiding a mark frame of a vertex of the three-dimensional graph; and when the change of the three-dimensional graph is detected to be finished, updating the marking position of the vertex after the change of the three-dimensional graph, and displaying the marking frame corresponding to the vertex according to the updated marking position.

The automatic adjustment of the position of the mark frame may be calculated according to a preset default position algorithm of the mark frame, which is not specifically limited in this embodiment.
For example, in the process of changing the solid pattern, the "visibility" of the mark frame may be set to "false" in the program of the whiteboard software, so that the whiteboard software hides the mark frame corresponding to the vertex in the process of changing the solid pattern, that is, the mark frame is not presented, and the hiding effect is achieved; after the change is finished, the ridge projection information of each vertex is recalculated, the position of the marking frame is redetermined through the projection included angle of the ridge of the vertex, the marking frame corresponding to the vertex is displayed according to the redetermined position of the marking frame, the purpose of automatically adjusting the vertex marking position is achieved, the vertex marking position does not need to be manually adjusted by a user, the user operation is simplified, and the vertex marking efficiency after the stereo graph is changed is improved.
