Fig. 2 is please referred to, Fig. 2 is a kind of flow chart of surgical simulation method provided in an embodiment of the present invention, the method packet
Include following steps：
Step S110：Obtain 3D rendering information of the operation tool when being performed the operation.
When being performed the operation, real-time recording can be carried out by camera, the image information got is sent to by camera
Above-mentioned electronic equipment, however since the image information that camera obtains may be 2D images, so electronic equipment is obtaining 2D
Need reconvert at 3D rendering after image.Certainly the 3D figures of operation tool in the course of surgery can be also directly acquired by camera
As information.
Step S120：Based on position of the operation tool in the 3D models being pre-created described in the 3D rendering acquisition of information
Information.
3D models pre-establish, and in order to be simulated to surgical procedure, can establish model to the organ of human body, i.e.,
3D models include 3D organ models, are added with collision body in the 3D organ models in advance, i.e., when creating 3D models, by 3D moulds
Collision body is added in type, collision body can using gridding resource and build its impinger based on the grid.It wherein, can be to each
Correspondence adds collision body to organ respectively respectively, i.e., the collision body between each organ is independent, can be independently controlled.
In order to simulate in surgical procedure operation tool and human organ whether actual contact, so human organ is all added
Network impinger is used as collision body, the operation tool in 3D models is added rigid body, because collision body is the one of physical assemblies
Class, rigid body allow object by physical control, and collision body will be added to ability in the related object in 3D models together with rigid body
Can be that other grid collision bodies touch in the grid collision body labeled as protrusion when triggering collision, and carrying out collision detection
Hit, you can with by the corresponding grid mark of target organ be protrusion, using collision body detect the target organ whether with its
He collides collision body, and if target organ is heart, the corresponding cardiac module of heart is added with collision body, and is labeled as
Protrusion, if then perform the operation to heart, operation tool can be by collision physical examination when colliding the corresponding grid of the heart
It measures, then it represents that the operation tool is collided with heart during actual operation, such as contact.
And after the 3D rendering information for obtaining operation tool, it can get operation tool corresponding position letter in 3D models
Breath, specifically, position coordinates that can be based on the 3D rendering information acquisition operation tool in 3D rendering information then will be described
Position coordinates are converted to the coordinates of targets in 3D models, and the coordinates of targets is position of the operation tool in the 3D models
Confidence ceases, then can be obtained location information of the operation tool in 3D models.
Step S130：Based on the location information judge the operation tool whether with the target in the 3D organ models
The corresponding collision body of organ collides.
After obtaining location information of the operation tool in 3D models, judge the operation tool whether with target organ pair
The collision body answered collides, i.e., location information of the collision body based on operation tool detect operation tool distance objective organ it
Between distance, at a distance from operation tool is between target organ be 0 when, then it represents that operation tool is touched with target organ
It hits, in order to simulate whether operation tool acts on target organ, then can be added for collision body corresponding when adding collision body
Attribute information, as material, radius, center, size (the impinger size i.e. in X, Y, Z three-dimensional) and operation tool collide
The simulation reaction of generation when the target organ is generated vibrations reaction, is cured with this to remind when colliding heart such as operation tool
Raw, operation tool is collided with target organ.In order to which target organ is accurately positioned, can refer to add target organ
Collision body can not generate simulated crash reaction, be mesh to indicate the organ not then if operation tool touches other organs
Organ is marked, is that can generate simulated crash reaction if operation tool is contacted with target organ, is achieved in the accurate of target organ
Positioning, by simulation reaction, that is, can be known, the target organ is the organ performed the operation to doctor, you can carries out subsequent hand
Art process.
The object in 3D models can be made to become lively in addition, collision body is used in combination with rigid body, rigid body allow object by
Physical control, and collision body allows object mutually to collide, so can also add collision body in operation tool, i.e., in 3D models
In further include having 3D operation tool models, in the 3D operation tool models in advance be added with collision body, then can be based on the operation
The location information of tool judge the operation tool in the 3D operation tools model corresponding collision body whether with the 3D
The corresponding collision body of target organ in organ model collides, and when to be, simulated crash reaction occurs, specifically, can
Location information based on the operation tool judges that the operation tool corresponding grid in the 3D operation tools model is
No grid corresponding with target organ in the 3D organ models collides, and when to be, simulated crash reaction occurs.
And two objects for being added to collision body cannot be collided mutually, unless they are labeled as protrusion, so, it can be by target
The corresponding collision body of organ is labeled as protrusion, and raised collision body must be shorter than 255 triangles, so can be in operation tool model
In also add collision body, also can detect operation tool whether collide with target organ.
When judging that operation tool collision body corresponding with the target organ in the 3D organ models collides,
Executing step S140：Simulated crash reaction occurs.It, can be with i.e. when operation tool collides the corresponding collision body of target organ
Send out the reactions such as vibrations, auditory tone cues so that doctor can perceive, so that surgical procedure is smoothed out.
In addition, as an implementation, after step s 140, the method, which may also include, obtains the operation tool
The collision depth information that collision body corresponding with the target organ in the 3D organ models collides；It is deep based on the collision
It spends information and generates corresponding simulated crash reaction.
Specifically, after judging that operation tool collides with target organ, also it can be obtained based on the dynamics of its collision
Collide depth information, for example, the image information that deform upon of target organ when can be collided by obtaining, with target organ not with hand
Image information before art tool collision is compared, such as can get its displacement information generated in X, Y, Z axis, then can be incited somebody to action
The vector sum of displacement information on three axis as collision depth information, so as to based on different collision depth informations come
Different simulated crash reactions is generated, when such as collision depth information is larger, simulated crash reacts the shake that can generate the long period
Dynamic reaction, when collision depth information is smaller, simulated crash reaction can generate vibrations reaction of short period etc..
