In order to acquire a three-dimensional model of a scan object, the scan object needs to be first scanned with an imaging device. The imaging device scans the scanning object to obtain scanning data, and generates an image sequence according to the scanning data. Wherein the medical image sequence is an image of each cross section of the scan object in the scan direction. And finally generating a three-dimensional model of the internal structure of the scanning object according to the image sequence. Wherein the imaging device may be: x-ray imaging instruments (Xray), CT (plain CT, spiral CT), positive sub-scanning (PET), magnetic resonance imaging (MR), infrared scanning devices, endoscopes, US, and combinations of multiple scanning devices, etc. When the three-dimensional model is acquired, in order to evaluate the scanning object, a user needs to repeatedly adjust the display angle of the three-dimensional model to inspect the scanning object, which results in complicated inspection steps and easy missing of the important area of the scanning object, resulting in an evaluation error.
It may be understood that the scan object may include any kind of physical object, including but not limited to a patient and an industrial device, where in the embodiment of the present invention, the patient is used for example analysis, and when the three-dimensional model is a three-dimensional model of the patient, after an image corresponding to the patient is acquired based on the imaging device, the three-dimensional model is acquired based on the image.
Referring to fig. 2, a first embodiment of the present invention provides a display control method of a three-dimensional model, the display control method of the three-dimensional model including:
step S10, identifying a target area in a three-dimensional model, wherein the three-dimensional model is a three-dimensional model determined by three-dimensional modeling of an image through a preset neural network algorithm;
step S20, obtaining attribute information of the target area;
step S30, determining a target view angle of the three-dimensional model according to the attribute information;
step S40, obtaining initial preset weights corresponding to the target view angles;
and S50, displaying the view angle image corresponding to the target view angle according to the initial preset weight.
In this embodiment, before the target area of the three-dimensional model is identified, the image may be obtained by forming an image of a scan object by using an imaging device such as an X-ray imaging instrument (Xray), CT (common CT, spiral CT), positive sub-scan (PET), magnetic resonance imaging (MR), an infrared scanning device, an endoscope, US, and a combination scanning device of multiple scanning devices, and obtaining the three-dimensional model of the scan object according to the image by using a preset neural network algorithm, where the scan object may be an organ, a tissue, or a cell set that needs to be observed by a patient, or may be a component that needs to be observed by an industrial device, and it may be understood that the imaging device may obtain the three-dimensional model of different real objects by using preset scan parameters.
Optionally, the three-dimensional model is acquired based on a volume rendering mode.
Optionally, the three-dimensional model includes a target area and a non-target area of the scanned object, where the target area is an object that is emphasized by a user.
Optionally, the identifying the target area of the three-dimensional model may be that the user observes the three-dimensional model, determines the target area in the three-dimensional model, further receives user input, determines the target area in the three-dimensional model according to the user input, and further displays the target area in a preset manner, where the preset manner may be that the outline of the target area is outlined, the target area is highlighted, or the target area is intercepted by a frame to display. For example, when a doctor observes a three-dimensional model of a patient, the target region may be a lesion region, and after the doctor determines the lesion region of the three-dimensional model, the determined lesion region is input, and then the lesion region is displayed in a preset manner according to the doctor input.
Optionally, identifying the target area of the three-dimensional model may be acquired based on a neural network algorithm, and the step S10 includes:
And identifying the target area in the three-dimensional model according to a preset neural network algorithm.
Specifically, the three-dimensional model is input into a preset neural network algorithm which is obtained based on image training set training, and a target area is obtained through extraction and matching of features or variables. The preset neural network algorithm can acquire a large number of training sets of images for training the neural network, the training images can be two-dimensional images or three-dimensional images acquired by any imaging equipment, and the neural network is trained on the basis of machine learning through learning features or variables of the images.
Optionally, the attribute information includes at least one of short and long path information of the target area, volume information of the target area, projection area information of the target area, position information of the target area, association information of the target area and an adjacent area, property information of the target area, and knowledge-graph relationship information corresponding to the target area.
Optionally, determining a target view angle of the three-dimensional model according to the attribute information, where the target view angle is a preferred view angle that a user can quickly observe a scanned object when observing the three-dimensional model, for example, when a doctor observes a three-dimensional model of a patient, the target view angle may be a line of sight corresponding to a maximum projection area of the focal region, or may be a line of sight corresponding to a vascular tissue corresponding to the focal region. It can be understood that the target areas have different attributes and different corresponding target viewing angles.
Optionally, the mode of acquiring the target viewing angle may be determining a maximum projection area based on projection area information of the target area, determining a normal direction of the maximum projection area, and determining a preset viewing angle of the target area according to the normal direction. For example, when a doctor refers to a three-dimensional model of a patient, in order to more clearly observe a focal region, the maximum projection area corresponding to the focal region is given to the user, so that the doctor can quickly see the focal region.
Optionally, the three-dimensional model further includes an adjacent region adjacent to the target region, and the method for obtaining the target viewing angle may further include determining a shortest distance between the target region and the adjacent region based on the position information of the target region, and further determining the target viewing angle of the target region according to a normal direction corresponding to the shortest distance. For example, when a doctor refers to a three-dimensional model of a patient, it is necessary to judge whether or not an important organ or blood vessel in a non-target area is close to the focal area, thereby circumventing the influence on the important organ or blood vessel in the non-target area in the subsequent treatment of the focal area.
It can be understood that the method for acquiring the target viewing angle is not limited to the two modes, in actual operation, the terminal stores the mapping relation between the attribute information of the target area and the target viewing angle, and after the user inputs the three-dimensional model, multiple different target viewing angles are automatically matched for the user according to the attribute information of the target area of the three-dimensional model and the mapping relation, and the viewing angle images corresponding to the target viewing angles are displayed to the user.
Optionally, after the target view angles of the three-dimensional model are acquired, initial preset weights of the target view angles are determined. Optionally, the initial preset weights corresponding to the target viewing angles may be different or the same.
Optionally, the mapping relationship between the attribute information of the target area and the target view angle further includes an initial preset weight of each target view angle, and it can be understood that the size of the initial preset weight corresponding to each target view angle is different, where the initial preset weight is used to represent the useful degree of the target view angle, the higher the initial preset weight is, the higher the corresponding useful degree is, the higher the important degree of the target view angle is represented, and conversely, the lower the weight is, the lower the corresponding useful degree is, and the importance degree of the view angle to be targeted is represented. In the actual operation process, when generating a target view angle corresponding to a target area in the three-dimensional model, matching a corresponding initial preset weight for the target view angle according to the mapping relation. For example, in a three-dimensional model of a patient checked by a doctor, in order to better evaluate a lesion and determine a treatment plan, when the three-dimensional model is observed, a normal direction of a maximum projection area of a lesion area is determined as a preferred observation view angle, an initial preset weight of a target view angle corresponding to the normal direction of the maximum projection area of the lesion area is set to be higher, and when a position of the lesion area is not close to a blood vessel or an important organ, a manner of determining the target view angle based on association information of the lesion area and an adjacent area is not high for a user, and an initial preset weight corresponding to association information of the target area and the adjacent area is set to be lower.
In a specific operation, the attribute information of the target area in the three-dimensional model is acquired, a better target view angle is automatically matched for the three-dimensional model, initial preset weights of all the target view angles are automatically matched according to the attribute information of the current target area, and then the target view angles are sequentially displayed for a user according to the initial preset weights.
Optionally, after the target view angle of the three-dimensional model is obtained, the computer forms a view angle image corresponding to the target view angle according to the target view angle, and further sequentially displays the view angle image corresponding to the target view angle to a user according to the initial preset weight, for example, when a doctor observes the three-dimensional model of a patient, the doctor generates the view angle image corresponding to the maximum projection area of the three-dimensional model when the target view angle a is a view line corresponding to the maximum projection area of the focus area, and generates the view angle image corresponding to the association information of the focus area and the adjacent area when the target view angle B is a view line corresponding to the association information of the focus area and the adjacent area. Meanwhile, the initial preset weight corresponding to the target visual angle A is calculated to be 100 by a computer, and the initial preset weight corresponding to the target visual angle B is 50, so that the visual angle image corresponding to the target visual angle A is arranged in front of the visual angle image corresponding to the target visual angle B, and a doctor can quickly evaluate the focus area according to the visual angle image.
Alternatively, the view angle image may be acquired based on a surface rendering manner.
In the embodiment of the application, the target view angles are acquired through the attribute information of the target area in the three-dimensional model, and the initial preset weights are allocated to the target view angles, so that the view angle images corresponding to the target view angles are sequentially displayed to the user according to the initial preset weights, so that the user can conveniently view the three-dimensional model, the problem that the user needs to manually adjust the display angles of the three-dimensional model for multiple times when observing the three-dimensional model is solved, and the efficiency of the user in evaluating the scanning objects corresponding to the three-dimensional model is improved.
Optionally, the three-dimensional model includes a plurality of different viewing angles, so that in order to enable the user to better view the three-dimensional model, avoiding missing some important parts and causing erroneous judgment on the scanned object, based on this, referring to fig. 3, the step S50 in the second embodiment of the present application includes:
step S51, comparing initial preset weights corresponding to the target view angles;
and step S52, displaying the view angle images corresponding to the target views in a preset display mode based on the sequence from the initial preset weight to the initial preset weight, and outputting prompt information, wherein the preset display mode comprises overlapping and displaying the view angle images and the three-dimensional model.
In this embodiment, after the initial preset weights of the target view angles are obtained, view angle images corresponding to the target view angles may be displayed on a display interface of the terminal according to the order from large to small, and a user may determine which target view angles are useful view angles and which may be unimportant view angles based on the distribution sequence of the target view angles in the display interface.

Optionally, in a further embodiment, the three-dimensional model is separately displayed in a display interface for a user to observe the three-dimensional model when the three-dimensional model is acquired.
Optionally, in another embodiment, after the target area of the three-dimensional model is acquired, according to a cross-sectional view corresponding to the target area, the cross-sectional view and the three-dimensional model are displayed in the display interface in a superimposed manner, so that a user can quickly diagnose the target area according to the cross-sectional view.

When a doctor actually browses the visual angle image, the surgical treatment route aiming at the three-dimensional model needs to be planned according to the visual angle image, important organs and/or blood vessels needing to be avoided in the actual surgical process need to be judged in the process of planning the surgical treatment route, and meanwhile, the positions inconvenient to operate in the actual operation process need to be avoided. Therefore, it takes a long time for the doctor to observe and think. Based on the above, the embodiment of the invention provides a method for outputting prompt information, and a doctor determines a surgical treatment route faster according to the prompt information.
Optionally, the hint information includes, but is not limited to, vital organs and/or vessels that need to be evaded, and an operative location. For example, when a doctor observes a three-dimensional model of a patient, the target area is a lung, adjacent positions of the lung are distributed over blood vessels, and the blood vessels need to be avoided during subsequent operation treatment of the doctor to prevent the patient from suffering from massive hemorrhage. In addition, the doctor also needs to judge which positions are inconvenient to operate when the target area is subjected to surgical treatment, and automatically output prompt information to the user based on the blood vessel and the positions so that the user can adjust a surgical treatment route based on the positions.

Or the terminal can also mark the prompt information and play the voice at the same time.
It is understood that the preset modes include, but are not limited to, the above three modes.
According to the method, all the target view angles are displayed in sequence from large to small according to the initial preset weight, namely, the target view angles with low initial preset weight are arranged at the back of a display interface, the target view angles with high initial preset weight are arranged at the front of the display interface, so that a user can conveniently and quickly browse view angle images from the front of the display interface, and prompt information is output to the user, so that the user can better evaluate the three-dimensional model according to the prompt information.
Optionally, referring to fig. 4, based on the second embodiment, step S50 in the third embodiment of the present application further includes:
and step S53, determining viewing angle parameters according to the three-dimensional model and a target viewing angle, wherein the viewing angle parameters comprise at least one of aperture, focal length and depth of field.
And step S54, displaying the view angle image corresponding to the target view angle according to the view angle parameter and the initial preset weight.
In this embodiment of the present application, the aperture is used to control the light incoming amount, the terminal obtains the image information of the target area, determines the image brightness of the display position corresponding to the target area, and when the image brightness does not meet the preset brightness threshold, it is difficult to see the image details of the display position corresponding to the target area, and increases or reduces the aperture, so that the image brightness of the display position corresponding to the target area meets the preset brightness threshold, and thus, the user can clearly detect the image details of the target area in the three-dimensional model according to the adjusted viewing angle parameter.
The focal length is used for controlling the distance between the three-dimensional model and the user, after the terminal acquires the image information of the target area, whether the distance between the target area and the user does not meet a preset distance threshold value is judged, and when the distance does not meet the preset distance threshold value, the focal length is increased or reduced, so that the user can clearly detect the image details of the target area matched with the three-dimensional model according to the adjusted focal length.
The depth of field is used for controlling the distance between clear images presented in the range before and after the focus of the three-dimensional model, and the terminal automatically adjusts the depth of field parameters according to the image information after acquiring the image information of the target area.
It is understood that the viewing angle parameters include, but are not limited to, aperture, focal length, and depth of field.
In an actual operation process, after a user uploads the three-dimensional model to a terminal, the terminal obtains a target area of the three-dimensional model and attribute information of the target area according to the three-dimensional model, automatically matches a target view angle for the user according to the attribute information, and automatically obtains view angle parameters according to the three-dimensional model and the target view angle, and further displays view angle images corresponding to the target view angle according to the view angle parameters and initial preset weights, so that the user observes the three-dimensional model based on a proper distance, a proper brightness and a proper view angle.

Step S70, adjusting the weight corresponding to the target visual angle according to the current browsing duration and/or the historical browsing duration;
and S80, determining the next preset weight corresponding to the target view angle according to the adjusted weight, so that when the view angle image corresponding to the target view angle is displayed next time, the view angle image corresponding to the target view angle is displayed in a sequence from large to small according to the next preset weight.
In this embodiment of the present application, the terminal is configured with a timing device, and when a user browses the view angle image based on his own needs, the browsing duration of the user browses the view angle image is recorded and saved, where the browsing durations of the view angle images may be different or the same.
In general, when a user actually browses the visual angle image, the user views the visual angle image corresponding to the self requirement according to the self requirement, if the browsing time is long, the visual angle image importance degree is higher, and if the browsing time is short, the visual angle image importance degree is lower.
Optionally, after the current browsing duration corresponding to the view angle images corresponding to the target view angles is obtained, the weight of the target view angles is adjusted according to the current browsing duration. And if the weight of the target view angle corresponding to the view angle image with the longest current browsing duration is adjusted to be the highest, the weight corresponding to the corresponding target view angle with the shortest current browsing duration is adjusted to be the highest. For example, the current browsing duration of the view angle image a is 10min, the current browsing duration of the view angle image B is 9min, the current browsing duration of the view angle image C is 3min, and so on, after the current browsing duration is determined, the weight of the target view angle corresponding to the view angle image a is adjusted to 100, the weight of the target view angle corresponding to the view angle image B is adjusted to 90, and the weight of the target view angle corresponding to the view angle image C is adjusted to 80.
Optionally, after the browsing duration corresponding to the view angle image corresponding to each target view angle is obtained, the historical browsing duration corresponding to each view angle image is obtained at the same time, wherein the historical browsing duration is the historical browsing duration obtained by each view angle image before current browsing. Based on this, the manner of adjusting the weight of the target view angle according to the browsing duration may further be to record and store, at the terminal, a current browsing duration of each view angle image by the user, and based on the historical browsing duration, by overlapping the current browsing duration with the historical browsing duration, and further adjust the weight of the view angle image based on the overlapped browsing duration. For example, the historical browsing duration of the view angle image a is 1200s, the historical browsing duration of the view angle image B is 2000s, the browsing duration of the current browsing view angle image a is 60s, the browsing duration of the current browsing view angle image B is 100s, the superimposed browsing duration corresponding to the view angle image a is 1290s, the superimposed browsing duration corresponding to the view angle image B is 2100s, the importance degree corresponding to the view angle image B is judged to be high based on the fact that the superimposed browsing duration corresponding to the view angle image B is longer than the superimposed browsing duration corresponding to the view angle image a, the weight of the target view angle corresponding to the view angle image B is increased, and the weight corresponding to the target view angle corresponding to the view angle image a is reduced, so that the next preset weight of the view angle image B is greater than the next preset weight of the view angle image a.

It will be appreciated that the importance of the marked viewing angle image is greater than the importance of the unmarked viewing angle image, the more text information the higher the importance of the viewing angle image. Based on the above, the current browsing duration corresponding to each view angle image is recorded and stored, the view angle image corresponding to the voice information is marked according to the corresponding voice information, and then the weight corresponding to the target view angle corresponding to the view angle image is adjusted according to the mark and the corresponding current browsing duration.
