Embodiments of the present application will be described below with reference to the accompanying drawings.
The execution subject of the method embodiments described below may be a model display device, which may be implemented as part or all of the computer apparatus by software, hardware, or a combination of software and hardware. The following method embodiments are described taking an execution subject as a computer device as an example.
Fig. 2 is a flow chart of a model image display method according to an embodiment. The embodiment relates to a specific process that a computer device rotates and displays a model to be displayed based on a rotation instruction input by a user, as shown in fig. 2, and the method includes:
s10, acquiring a rotation matrix corresponding to a target rotation angle; the target rotation angle is determined based on a rotation instruction input by a user by taking a target planning path as a rotation center axis of a model to be displayed.
Specifically, the computer device may obtain the rotation matrix corresponding to the target rotation angle, which may be the rotation matrix stored in the read memory, or may receive the rotation matrix sent by other devices, or may obtain a rotation instruction input by the user, calculate the target rotation angle according to the rotation instruction, and calculate the rotation matrix according to the target rotation angle. The rotation matrix can represent the rotation amount of the user input required to rotate. For example, if the rotation amount represented by the rotation instruction input by the user is large, the target rotation angle is large, and thus the rotation amount represented by the obtained rotation matrix is large; if the rotation quantity represented by the rotation instruction input by the user is small, the target rotation angle is small, and therefore the rotation quantity represented by the obtained rotation matrix is small.
S20, acquiring an initial world transformation matrix of the model to be displayed in an initial state; the initial world transformation matrix is used for representing the pose of the model to be displayed before rotation.
Specifically, the computer device may read an initial world transformation matrix of the model to be displayed stored in the memory in an initial state, or may receive the initial world transformation matrix of the model to be displayed. It should be noted that, the above-mentioned initial world transformation matrix is used to represent the pose, i.e. the position and orientation, of the model to be displayed in the initial state, i.e. before the rotation of the model to be displayed has occurred.
And S30, fusing the rotation matrix and the initial world transformation matrix to obtain a matrix to be displayed corresponding to the pose of the model to be displayed after the model to be displayed rotates according to the rotation instruction.
Specifically, the computer device fuses the rotation matrix and the initial world transformation matrix, and may perform vector operation, such as vector superposition, or vector multiplication, on the rotation matrix and the initial world transformation matrix, so as to realize superposition of the rotation matrix on the initial world transformation matrix, and obtain the to-be-displayed matrix representing the pose of the to-be-displayed model after rotating according to the rotation amount corresponding to the rotation instruction.
And S40, displaying the image of the model to be displayed according to the matrix to be displayed.
Specifically, since the matrix to be displayed can represent the pose of the model after the model to be displayed rotates according to the rotation instruction, the computer equipment displays the model to be displayed according to the pose represented by the matrix to be displayed, so that the image display of the pose of the model to be displayed after the model to be displayed rotates according to the rotation instruction can be realized.
In this embodiment, since the target rotation angle is a rotation angle determined based on a rotation instruction input by a user and taking a target planned path as a rotation center axis of the model to be displayed, the computer device obtains a rotation matrix corresponding to the target rotation angle, obtains an initial world transformation matrix representing a pose of the model to be displayed before rotation of the model to be displayed in an initial state, and fuses the rotation matrix and the initial world transformation matrix to obtain a pose corresponding to the pose of the model to be displayed after rotation according to the rotation instruction, where the pose to be displayed can represent the pose of the model to be displayed after rotation of the model to be displayed based on the target rotation angle required by the user. According to the method provided by the embodiment, the rotation matrix and the initial world transformation matrix are fused to obtain the matrix to be displayed corresponding to the pose of the model to be displayed after rotating according to the rotation instruction, so that the problems of limited observation angle and complex operation caused by continuously switching needle tracks when observing surrounding tissues at multiple angles in the traditional technology are avoided.
Optionally, on the basis of the foregoing embodiment, the initial world transformation matrix includes an initial coronal bit matrix, an initial sagittal bit matrix, and an initial transverse bit matrix, and the matrix to be displayed includes a coronal bit matrix to be displayed, a sagittal bit matrix to be displayed, and a transverse bit matrix to be displayed; one possible implementation manner of the step S30 may include: multiplying the rotation matrix and the initial coronal bit matrix to obtain a coronal bit matrix to be displayed; multiplying the rotation matrix and the initial sagittal matrix to obtain a sagittal matrix to be displayed; multiplying the rotation matrix and the initial transverse position matrix to obtain a transverse position matrix to be displayed, so as to obtain the coronal position, sagittal position and constant position matrixes to be displayed respectively, and describing the model to be displayed from three different positions, so that the rotated model to be displayed is more comprehensively expressed, and is convenient to observe and use. Optionally, the computer device may further generate a matrix to be displayed of a shape bit corresponding to the selection instruction according to the selection instruction input by the user, which is not limited in the embodiment of the present application.
Optionally, the displaying coronal position matrix, the displaying sagittal position matrix, and the displaying transverse position matrix respectively represent the pose of the model to be displayed in three different positions, and in the practical use process, one possible implementation manner of the step S40 may include displaying the image of the model to be displayed in the corresponding display window according to the coronal position matrix to be displayed, the displaying sagittal position matrix, and the displaying transverse position matrix to be displayed. Specifically, each shape position can correspond to one display window, and different shapes of the model to be displayed can be displayed in different windows according to the rotated pose images, so that the model to be displayed can be displayed conveniently in different poses, the tissue distribution conditions under different shapes can be observed conveniently, and the use of a user is facilitated.
Alternatively, on the basis of the above embodiments, one possible implementation manner of the above step S10 may be as shown in fig. 3, including:
s11, generating the target planning path according to a path generation instruction input by a user.
Specifically, a path generation instruction input by a user is obtained, the path generation instruction comprises a plurality of coordinate points input by the user, and a center axis is generated according to at least more than two coordinate points to serve as a target planning path. For example, the computer device may take a connection of two coordinate points as a target planned path.
Alternatively, one possible implementation of this step may include: the method comprises the steps of obtaining the coordinate of the cranium entering point and the coordinate of the target point input by a user, determining the target planning path according to the connecting line between the coordinate of the cranium entering point and the coordinate of the target point, and determining the target planning path according to the connecting line between the coordinate of the cranium entering point and the coordinate of the target point, so as to obtain the target planning path matched with the input of the user, and further, the model to be displayed can rotate around a central axis expected by the user, so that the observation is more comprehensive, and the use is more convenient. Optionally, the computer device may further update a normal vector of the position corresponding to each display window according to the rotation matrix, so as to ensure that the position of each display window can be displayed based on the front surface, so as to facilitate observation and subsequent calculation. Optionally, fig. 3a is a schematic diagram of multi-bit MPR rotation interaction of a single path, fig. 3b is a schematic diagram of multi-bit MPR rotation interaction of multiple paths, and straight lines in the diagram are different planned paths.
Optionally, the number of the cranium-entering point coordinates and the number of the target point coordinates are multiple, and the cranium-entering point coordinates and the target point coordinates are in one-to-one correspondence; one possible implementation manner of the step of determining the target planning path according to the connection line between the cranientry point coordinate and the target point coordinate may further include: taking the connecting line between each cranium-entering point coordinate and the corresponding target point coordinate as an initial planning path to obtain a plurality of initial planning paths; receiving a path clicking instruction input by a user; and determining the target planning path from a plurality of initial planning paths according to the path clicking instruction. Specifically, the computer device may obtain a plurality of the cranium-entering point coordinates and a plurality of the target point coordinates input by the user, where the cranium-entering point coordinates and the target point coordinates are in one-to-one correspondence, and a connection line between each cranium-entering point coordinate and the corresponding target point coordinate may be used as an initial planning path. The computer device then receives a path clicking instruction input by the user, for example, may receive a selection instruction of clicking one of the initial planned paths with a mouse, and regards the clicked one as the target planned path. Alternatively, at this time, the icon of the mouse may be converted into a rotated icon representation into a state capable of being displayed in a rotated manner. In the implementation manner, the connecting line between each cranium-entering point coordinate and the corresponding target point coordinate is used as an initial planning path to obtain a plurality of initial planning paths, and the path point selection instruction input by the user is received, so that the target planning path is determined from the plurality of initial planning paths, and the target planning path can rotate along the central axis expected by the user, so that the observation is more comprehensive and the use is more convenient.
S12, converting the rotation instruction input by the user into the target rotation angle.
Specifically, the computer device may receive a rotation instruction input by a user through the external device, for example, an operation of sliding the mouse on the screen, and convert the rotation instruction into a target rotation angle corresponding to the rotation instruction, for example, according to a distance of sliding the mouse on the screen, to generate a target rotation angle corresponding to the distance and requiring rotation of the model.
S13, generating the rotation matrix based on the target planning path according to the target rotation angle.
Specifically, according to the target rotation angle, the computer equipment generates a rotation matrix representing the pose change quantity of the model by taking the target planning path as a central axis. Optionally, in the actual use process, the user can click the model through the left button of the mouse and drag a certain distance so as to realize the display after the conversion angle of the model to be displayed. Alternatively, multiple windows may simultaneously display images of various positions at that angle during the model rotation, thus facilitating multi-angle viewing.
In this embodiment, the computer device may generate an instruction according to a path input by a user, generate a target planned path, convert a rotation instruction input by the user into a target rotation angle, and finally generate a rotation matrix representing a pose variation amount of a model to be rotated according to the target rotation angle based on the target planned path, thereby implementing automatic determination of a rotation matrix which is expected to be matched with the user based on the target planned path and the rotation instruction determined by the user, so that rotation and display of the model based on any axis and angle defined by the user can be implemented, so that the display angle of the model is more various, and the operation is more convenient.
