Description

The system that a kind of three-dimensional software control is taken

Technical field

The utility model relates to a kind of Machinery Control System, particularly a kind of system that utilizes three-dimensional software control machinery.

Background technology

Though it is not long that computer graphical is made the industry generation time, really be the irrealizable picture of scene because it can realize many, so speed of development is quite swift and violent.

Films and television programs even content that may 80% are all finished by computer photograph.And this is wherein in order to allow picture look truer, and a lot of things all are that actual situation is in conjunction with handling.Increasing robot has appeared in the shooting of film.Therefore in high-quality video display special efficacy is made, usually need digital effects is combined with mechanical model, realize perfect effect.Yet, aspect mechanical model control, often by the manual remote control operation demonstration, the three-dimensional animation coupling that needs and computer generate.This often needs a group to repeat, and repeatedly taking just may success.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of system of three-dimensional software control shooting, is used to address the above problem.

In order to achieve the above object, the system that the utility model provides a kind of three-dimensional software control to take, 1. a three-dimensional software is controlled the system of taking, and it comprises: solid model, described solid model has a plurality of articulation points; Dummy model, described dummy model is based upon in the Computerized three-dimensional software, has and the related articulation point in described solid model joint; Computing machine, the angle of obtaining described dummy model articulation point according to three-dimensional software changes; Servomotor is connected on the articulation point of described solid model, is used for changing according to the angle steering order angle in each joint of solid model; Micro-control unit links described servomotor and computing machine, and the angle that is used for the dummy model articulation point that will obtain from described computing machine changes and converts the angle steering order to and send to servomotor.

The system of the utility model employing maya synchro control mechanical hook-up can be directly by making animation in maya, driven in synchronism external mechanical devices then, abandoned original RC telechirics, make the control of electric-controlled mechanical model become very easy, realize the perfect adaptation in machinery and digital special school.The utility model can also be expanded and be used for tele-medicine, virtual reality, and etc. Long-distance Control, fields such as robot control.

Description of drawings

Fig. 1 is the structured flowchart of a specific embodiment of system of a kind of three-dimensional software control of the utility model shooting.

Embodiment

Please referring to shown in Figure 1, the utility model provides a kind of system of three-dimensional software control shooting, and it comprises with the lower part.

Solid model, described solid model has a plurality of articulation points.

Dummy model, described dummy model is based upon in the Computerized three-dimensional software, has and the related articulation point in described solid model joint.

In a specific embodiment, described dummy model is a skeleton model.Because utilize three-dimensional software control physical objects to be taken not need to allow dummy model follow physical objects in full accord.The structure that only needs dummy model to have with the physical objects unanimity gets final product.Consistent structure comprises the distance between the articulation point of consistent joint position, equal proportion etc.In the process that dummy model is made, should become equal proportion with solid model as far as possible, controlling like this can be more convenient, is unlikely to occur mistake.

The related mode correspondence that can adopt mapping table or register of all articulation points of object to be shot with the dummy model articulation point.The corresponding control signal of having avoided with the articulation point of physical objects of dummy model is sent wrong steering order.

Computing machine, the angle of obtaining described dummy model articulation point according to three-dimensional software changes.

Traditional mode is that artificial Long-distance Control is waited to take the action of physical objects and moved, and the unavoidable bad operating speed of control that occurs is held bad operation opportunity, operates situations such as excessive easily.The utility model is made animation with the action and the movement locus of object to be shot, has guaranteed the standardization of its action, have simultaneously can be well with picture in other guide merge.

In a specific embodiment, object to be shot is not that action is all arranged all the time, and all articulation points all have action to change when neither move at every turn.So those have the angle changing of the operating point of action variation just can reappear whole course of action only to need record.

Servomotor is connected on the articulation point of described solid model, is used for changing according to the angle steering order angle in each joint of solid model.

Micro-control unit links described servomotor and computing machine, and the angle that is used for the dummy model articulation point that will obtain from described computing machine changes and converts the angle steering order to and send to servomotor.

In a specific embodiment, described three-dimensional software is Maya, and it comprises the PORT COM that can Gong call.Described solid model is the machinery of servomotor control, and the turning joint point in its physical construction is corresponding with the articulation point of described dummy model.After described micro-control unit received the angle information of the variation that computing machine sends, the control servomotor was to the corresponding angle of articulation point rotation of solid model correspondence.

Detailed process is as follows.At first open PORT COM, set up communication with maya by function C apTcpOpen (servername).Send mel order (20ms) " getAttr objName.rx " to maya by this port at interval with certain hour then, after maya receives this order, carry out this order immediately, and by port with the form return results of character string to micro-control unit, micro-control unit writes down this result, and it is carried out corresponding data-switching and processing, obtain the articulation point angle value of dummy model.At last, micro-control unit is sent to the servomotor execution by the com port with data. ...

Wherein # is a start mark, and 00A is a port number, and XXX represents joint angles system,! Be end mark.

In like manner, adopt system of the present utility model to expand and be used for tele-medicine, virtual reality, etc. Long-distance Control, fields such as robot control.

The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement etc., all should be included within the protection domain of the present utility model.
