Abstract

The invention relates to an interaction module applied to a stereoscopic interaction system and a method of the interaction module. The interaction module and the method are used for correcting a position of an interaction component according to the position of a user, or correcting the position of a virtual article in a stereoscopic image and an interaction judgement condition. Therefore, even if the position of the virtual article in the stereoscopic image which is seen by the user is changed by the change of the position of the user, the stereoscopic interaction system can obtain an accurate result according to the position of the corrected interaction component or the corrected position of the virtual article and the interaction judgement condition.

Description

Be applied to interactive module and the method thereof of stereoscopic interaction system

Technical field

The present invention relates to a kind of stereoscopic interaction system, more particularly, relate to a kind of three-dimensional display system that utilizes and carry out interactive stereoscopic interaction system.

Background technology

In known technology, three-dimensional display system is used to provide stereopsis.As shown in Figure 1, three-dimensional display system can be divided into bore hole formula three-dimensional display system and eyeglass stereoscopic display system.For example, the bore hole formula three-dimensional display system 110 in the left side of Fig. 1 utilizes the mode of light splitting, provides different image (such as the image DIM of Fig. 1 in different angles _{θ 1}～DIM _{θ 8}).So, because user's eyes are positioned at different angles, so the user can receive respectively left image DIM _L(image DIM _{θ 4}) and right image DIM _R(image DIM _{θ 5}), and obtain according to this stereopsis that bore hole formula three-dimensional display system 110 provides.Eyeglass stereoscopic display system 120 at the right-hand part of Fig. 1 comprises display screen 121 and auxiliary eyeglasses 122.Display screen 121 is used to provide left image DIM _LWith right image DIM _R Auxiliary eyeglasses 122 is used for assisting user's eyes to receive respectively left image DIM _LWith right image DIM _R, to allow the user can obtain this stereopsis.

Yet the user can change along with user's position from the resulting stereopsis of three-dimensional display system.Take eyeglass stereoscopic display system 120 as example, as shown in Figure 2 (not shown auxiliary eyeglasses 122 in Fig. 2) has virtual objects VO (for example, virtual objects VO is tennis) in the stereopsis that three-dimensional display system 120 provides.Wherein virtual objects VO is at left image DIM _LIn the position be LOC _ILVO, at right image DIM _RIn the position be LOC _IRVOIf the position of user's left eye is LOC at this moment _1LE, the position of user's right eye is LOC _1REThe position LOC of user's left eye _1LEPosition LOC with virtual objects VO _ILVOForm straight line L _1LThe position LOC of user's right eye _1REPosition LOCI with virtual objects VO _RVOForm straight line L _1RSo, the user sees that the position of virtual objects VO is according to straight line L _1LWith L _1RAnd determine.For example, as straight line L _1LWith L _1RThe position of intersection point be LOC _1CPThe time, the user sees that the position of virtual objects VO is LOC _1CPIn like manner, be respectively LOC when user's eyes position _2LEWith LOC _2REThe time, the position of user's eyes respectively with the position LOC of virtual objects VO _ILVOWith LOC _IRVOForm straight line L _2LWith L _2RAt this moment, the user sees that the position of virtual objects VO is according to straight line L _2LWith L _2RAnd determine.That is to say, the user sees that the position of virtual objects VO is straight line L _2LWith L _2RThe position LOC of intersection point _2CP

Because the user from the resulting stereopsis of three-dimensional display system, can change along with user's position, therefore when user's wish is interactive by interactive module (such as Game device) and three-dimensional display system, may produce wrong interactive result.For example, user's wish is carried out three-dimensional tennis game by interactive module (such as Game device) and three-dimensional display system 120.Interactive assembly (such as the game control joystick) in the hand-held interactive module of user is with the batting of swinging the bat of the role in the control game.Interactive module (Game device) supposes that user's position is positioned at the dead ahead of three-dimensional display system, and interactive module (Game device) supposes that user's eyes position is respectively LOC _1LEWith LOC _1REAt this moment, interactive module (Game device) control three-dimensional display system 120 is at left image DIM _LThe position LOC of middle demonstration tennis _ILVO, at right image DIM _RThe position of middle demonstration tennis is LOC _IRVOTherefore, interactive module (Game device) supposes that the 3D tennis position that the user sees is LOC _1CP(as shown in Figure 2).In addition, as position and position LOC that the user swings the bat _1CPBetween distance less than interactive critical distance D _THThe time, interactive module (Game device) judges that namely the user hits tennis.Yet, if user's eyes position is actually LOC at this moment _2LEWith LOC _2RE, then the 3D tennis position in fact seen of user is LOC _2CPAssumed position LOC _2CPWith LOC _1CPBetween distance greater than interactive critical distance D _THSo, control interactive assembly (game control joystick) to position LOC as the user _2CPWhen swinging the bat, interactive module (Game device) judges that the user does not hit tennis.In other words, although the 3D tennis position that in fact user sees is LOC _2CP, and the user controls interactive assembly (game control joystick) to position LOC _2CPSwing the bat, but interactive module (Game device) judges that but the user does not hit tennis.That is to say, because user's eye position changes the distortion that causes stereopsis, therefore can cause the interactive relationship of interactive module (Game device) erroneous judgement user and article, produce incorrect interactive result, bring the user very large inconvenience.

In the 3rd embodiment of bearing calibration of the present invention, in fact interactive decision circuitry 324 sees stereopsis DIM according to the user _3DPosition (three-dimensional left eye coordinates LOC as shown in Figure 4 _{3D_LE}With three-dimensional right eye coordinate LOC _{3D_RE}), proofread and correct stereopsis DIM _3D(such as the virtual coordinates LOC of virtual objects VO _{3D_PVO}With interactive Rule of judgment COND _PVO), obtain correct interactive as a result RT.More particularly, interactive decision circuitry 324 is according to three-dimensional eyes coordinate LOC _{3D_EYE}(three-dimensional left eye coordinates LOC _{3D_LE}With three-dimensional right eye coordinate LOC _{3D_RE}), the virtual coordinates LOC of virtual objects VO _{3D_PVO}With interactive Rule of judgment COND _PVO, the viewing location that calculates as the user is three-dimensional eyes coordinate LOC _{3D_EYE}The time, in fact the user sees the position of virtual objects VO and the interactive Rule of judgment that the user should experience.So, interactive decision circuitry 324 can be according to position (the three-dimensional interactive coordinate LOC of interactive assembly 322 _{3D_PIO}), in fact the user see the position (coordinate behind as shown in Figure 4 calibrated) of virtual objects VO, and the interactive Rule of judgment that should experience of user (the interactive Rule of judgment behind as shown in Figure 4 calibrated), and determine correct interactive result.

Please refer to Figure 11 and Figure 12.Figure 11 and Figure 12 are the schematic diagram of the 3rd embodiment of explanation bearing calibration of the present invention.In the 3rd embodiment of bearing calibration of the present invention, interactive decision circuitry 324 is according to three-dimensional eyes coordinate (three-dimensional reference coordinate) LOC _{3D_EYE}Proofread and correct stereopsis DIM _3D, to obtain correct interactive as a result RT.More particularly, interactive decision circuitry 324 is according to three-dimensional eyes coordinate (three-dimensional reference coordinate) LOC _{3D_EYE}The virtual coordinates LOC of conversion virtual objects VO _{3D_PVO}For proofreading and correct virtual coordinates LOC _{3D_CVO}And interactive decision circuitry 324 is according to this three-dimensional eyes coordinate LOC _{3D_EYE}Change interactive Rule of judgment COND _PVOFor proofreading and correct interactive Rule of judgment COND _CVOThus, interactive decision circuitry 324 is according to three-dimensional interactive coordinate LOC _{3D_PIO}, proofread and correct virtual coordinates LOC _{3D_CVO}With the interactive Rule of judgment COND of correction _CVO, determine interactive as a result RT.For example, as shown in figure 11, the user is from three-dimensional left eye coordinates LOC _{3D_LE}With three-dimensional right eye coordinate LOC _{3D_RE}Watch stereopsis DIM _3DTherefore, interactive decision circuitry 324 can be according to straight line L _AL(three-dimensional left eye coordinates LOC _{3D_LE}With virtual objects VO in left image DIM _LPosition LOC _ILVOBetween straight line) with straight line L _AR(three-dimensional right eye coordinate LOC _{3D_RE}With virtual objects VO in right image DIM _RPosition LOC _IRVOBetween straight line), obtain the user from three-dimensional eyes coordinate LOC _{3D_EYE}The virtual objects VO that sees is at position LOC _{3D_CVO}Thus, interactive decision circuitry 324 can be according to three-dimensional eyes coordinate LOC _{3D_EYE}, proofread and correct virtual coordinates LOC _{3D_PVO}, in fact see the residing position of virtual objects VO (correction virtual coordinates LOC and obtain the user _{3D_CVO}).As shown in figure 12, interactive Rule of judgment COND _PVOFor according to interactive critical distance D _THDetermine with the position of virtual objects VO.Therefore, interactive Rule of judgment COND _PVOCan be considered centered by the position of virtual objects VO, with interactive critical distance D _THBe the formed critical surface SUF of radius _PTHWhen interactive assembly 322 enters critical surface SUF _PTHThe time, interactive decision circuitry 324 determines that interactive as a result RT represents " contact "; When interactive assembly 322 does not enter critical surface SUF _PTHThe time, interactive decision circuitry 324 determines that interactive as a result RT represents " not contact ".Because critical surface SUF _PTHCan be considered by many critical point P _THForm each critical point P _THThe position be its virtual coordinates LOC _PTH, therefore interactive decision circuitry 324 is utilized the illustrated method of similar Figure 11, can be according to three-dimensional eyes coordinate LOC _{3D_EYE}, obtain each critical point P that in fact user experiences _THCorrection virtual coordinates LOC _CTHThus, all critical point P _THCorrection virtual coordinates LOCC _THCan form the critical surface SUF after calibrated _CTHAt this moment, proofread and correct critical surface SUF _CTHBe and proofread and correct interactive Rule of judgment COND _COVThat is to say, as the three-dimensional interactive coordinate LOC of interactive assembly 322 _{3D_PIO}Enter and proofread and correct critical surface SUF _CTHThe time, interactive decision circuitry 324 determines that interactive as a result RT represents " contact " (as shown in figure 12).Thus, interactive decision circuitry 324 is according to three-dimensional eyes coordinate LOC _{3D_EYE}Recoverable stereopsis DIM _3D(the virtual coordinates LOC of virtual objects VO _{3D_PVO}With interactive Rule of judgment COND _PVO), see in fact that to obtain the user virtual coordinates LOC (is proofreaied and correct in the position of virtual objects VO _{3D_CVO}) the interactive Rule of judgment that in fact should experience with the user (proofreaies and correct interactive Rule of judgment COND _CVO).Therefore, interactive decision circuitry 324 can be according to the three-dimensional interactive coordinate LOC of interactive assembly 322 _{3D_PIO}, virtual coordinates LOC _{3D_CVO}With the interactive Rule of judgment COND of correction _CVO, correctly to determine interactive as a result RT.In addition, in the situation that general, interactive Rule of judgment COND _POVWith the interactive Rule of judgment COND of correction _COVDifference little, for example, critical surface SUF _PTHFor having radius D _THSphere, at this moment, proofread and correct critical surface SUF _CTHAlso be sphere, and its radius approximate greatly D _THTherefore in the 3rd embodiment of bearing calibration of the present invention, also can only proofread and correct the virtual coordinates LOC of virtual objects VO _{3D_PVO}, and do not proofread and correct interactive Rule of judgment COND _PVO, to save the required calculation resources of interactive decision circuitry 324.In other words, interactive decision circuitry 324 can be according to proofreading and correct virtual coordinates LOC _{3D_CVO}With interactive Rule of judgment COND originally _PVO, calculate interactive as a result RT.
