Embodiment
Below in conjunction with specific embodiment technical scheme of the present invention is described.
The display terminal control method process flow diagram of the embodiment of the invention comprises three steps as shown in Figure 1:
1, the change amount of calculated target positions draws the angle of described display terminal skew, produces deviation angle information.
The mode of calculating the position change amount of described target is at least a information in reception image information, acoustic information and the infrared information, change amount according to the described target location of described at least a information calculations draws the angle that described display terminal should be offset.The mode of reception information has three kinds usually: first kind is to obtain described target by camera, obtains the position of described target by image recognition; Second kind is by the sound input system, as MIC, obtains the sound in place, described display terminal place, discerns the direction and the sound intensity of maximum described sound, thereby obtains the position of described target; The third is by discern the position of described target according to reference coordinate of described goal-setting in infrared identification module.
The display terminal of the embodiment of the invention rotates reference coordinate definition synoptic diagram as shown in Figure 2, be set with X-axis and Y-axis both direction, when some angles are when target moves, be illustrated in figure 2 as 20 ℃, will obtain the offset coordinates of a target, thereby obtain the position of target.Before sending deviation angle information, further comprise, the setting-up time cycle, and in the described time cycle, send described deviation angle information.
2,, obtain rotational angle information according to deviation angle information and the parameter that presets.
When receiving the deviation angle information that the target location locating module sends, send rotational angle information according to the parameter that presets.The first-class auxiliary device of shooting can be arranged on the described display terminal.The described parameter that presets comprises rotation sensitivity parameter, the reaction sensitivity parameter of described display terminal and whether starts whether simultaneously information such as rotational parameters of display terminal rotational parameters, camera and display terminal.Rotate sensitivity parameter and be used for controlled target and depart from much angles and just drive display terminal and rotate, just need rotating screen etc. when departing from 10 ℃ of current angles.The reaction sensitivity parameter is used to control the time cycle of adjacent twice rotation of display terminal, such as the rotation time cycle be 2 seconds.Surpass the angle of reference position and the rotational response sensitivity parameter is set by the regulation corner, prevented that visual change from changing too soon or back and forth, improved the quality of reception of image.
3,, obtain rotational angle information according to deviation angle information and the parameter that presets.
The roller bearing that rotation command drives display terminal rotates, and follows the target rotation thereby drive display terminal.If have camera on the display terminal, then camera also can be along with display terminal rotates together.
The display terminal control device module diagram of the embodiment of the invention comprises as shown in Figure 3: target location locating module, rotation control module and rotation processing module.
The target location locating module is used for the change amount of calculated target positions, draws the angle that described display terminal should be offset, and sends deviation angle information.The composition structural drawing of the target location locating module of the embodiment of the invention specifically comprises as shown in Figure 4: information receiving module, position deviation calculation module and information sending module.
Information receiving module is used for receiving at least a information of image information, acoustic information and infrared information; Position deviation calculation module is used for the change amount according to the described target location of described at least a information calculations, draws the angle that described display terminal should be offset; Information sending module is used for the angle according to described skew, sends described deviation angle information.The target localization module further comprises timer module.Described timer module is used to set cycle regular hour, and in each time cycle, triggers the target location locating module and send deviation angle information.
Rotate control module and be used to receive described deviation angle information,, obtain and send rotational angle information according to the parameter that presets.
When described rotation control module receives the deviation angle information that the target location locating module sends, send rotational angle information according to the parameter that presets.Has the first-class auxiliary device of shooting on the described display terminal.The described parameter that presets comprises rotation sensitivity parameter, the reaction sensitivity parameter of described display terminal and whether starts whether simultaneously information such as rotational parameters of display terminal rotational parameters, camera and display terminal.Rotate sensitivity parameter and be used for controlled target and depart from much angles and just drive display terminal and rotate, just need rotating screen etc. when departing from 10 ℃ of current angles.The reaction sensitivity parameter is used to control the time cycle of adjacent twice rotation of display terminal, such as the rotation time cycle be 2 seconds.Surpass the angle of reference position and the rotational response sensitivity parameter is set by the regulation corner, prevented that the image change from changing too soon or back and forth, improved the quality of reception of image.
Rotate processing module: be used to receive and rotate the rotational angle information that control module sends, to described display terminal rotation command.The roller bearing that described rotation command drives display terminal rotates, and follows the target rotation thereby drive display terminal.If have camera on the display terminal, then camera also can be along with display terminal rotates together.
If use main camera and the auxiliary camera used simultaneously, when the master does not rotate with camera, need auxiliary camera acquired information to give the display terminal control device.Mainly in the situation that main flow and auxilliary stream are arranged, perhaps the meeting-place sends focus and the inconsistent situation of beholder to application scenarios.Application scenarios as: main see the main meeting-place with camera, auxiliary camera is seen speaker's situation.
Device among the embodiment of the application of the invention can allow display terminal follow target automatically and rotate, and helps the user receives the display terminal demonstration from the angle of the best information.Can use the meeting speaker of display terminal in the Conference Room, arbitrarily to demonstrate introduction like this to the other side, make things convenient for the aspectant interchange of both sides, application scenarios is as the introduction in object teaching, museum, can walk about and demonstrate the object that put in any one place, place the inside with being intended to the meeting-place, and can see the other side's reaction to the other side.Also can pass through infrared remote sensing captured target position, control camera and screen rotate, and can be applicable to personal terminal, as videophone.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
