[0030] 3D stereoscopic interaction can easily present certain difficult experimental scenarios, and can safely virtually present and operate simulations of certain difficult experimental scenarios, bringing a magical experience to users.

[0031] The present disclosure provides an interaction device and a 3D computer system.

[0032] Please refer to Figure 1 and Figure 2 , the present disclosure provides an interaction device applied to a 3D computer system. The 3D computer system includes a display 10; the interaction device includes a connecting rod 40, a first camera assembly 20, and a second camera assembly 30.

[0033] The connecting rod 40 is disposed on a side of the display 10 away from the display screen, and the length of the connecting rod 40 is adjustable.

[0034] Wherein the adjustable length of the connecting rod 40 enables the connecting rod 40 to adapt to displays 10 of various sizes. After determining the size of the display 10, the length of the connecting rod 40 is adjusted according to the size specification of the display 10, and then the connecting rod 40 is disposed on a side of the display 10 away from the display screen.

[0035] One end of the connecting rod 40 is connected to the first camera assembly 20, and the other end is connected to the second camera assembly 30. After the first camera assembly 20 and the second camera assembly 30 are connected to the connecting rod 40, they are respectively located on both sides of the display 10.

[0036] The midpoint of the connecting rod 40 coincides with the midpoint of the display 10, and the connecting rod 40 is horizontally arranged along the horizontal axis passing through the midpoint of the display 10. After the first camera assembly 20 and the second camera assembly 30 are connected to the connecting rod 40, they are symmetric with respect to the vertical axis passing through the midpoint of the display 10, so as to realize 3D stereo interaction between the first camera assembly 20 and the second camera assembly 30 and the display 10.

[0037] Among them, the connecting rod 40 is horizontally arranged along the horizontal axis passing through the midpoint of the display 10, so that the first camera assembly 20 and the second camera assembly 30 are horizontally arranged along the horizontal axis passing through the midpoint of the display 10 through the connecting rod 40.

[0038] When the first camera assembly 20 and the second camera assembly 30 are arranged on both sides of the display 10 in the above manner, 3D stereo interaction is realized through an interactive pen. Among them, the interaction space is transformed from a plane into a three-dimensional space, and it supports people to stand in front of the display 10 for three-dimensional interaction.

[0039] Further, the first camera assembly 20 includes a plurality of cameras 80, and the plurality of cameras 80 are arranged along the vertical direction on one side of the display 10, and the distance between adjacent cameras 80 is a set value.

[0040] Among them, please refer to Figure 3 , the camera 80 is an optical positioning camera, and the number thereof can be multiple. Optionally, the number of cameras 80 in the first camera assembly 20 provided in the present disclosure is two. When the number of cameras 80 in the first camera assembly 20 is two, the two cameras 80 are arranged along the vertical direction on one side of the display 10, and the two cameras 80 are symmetric with respect to the horizontal axis passing through the midpoint of the display 10.

[0041] Further, in order to better equip the first camera assembly 20, the first camera assembly 20 further includes a first angle fixing part and a first clamping part. The first camera assembly 20 is connected to the connecting rod 40 through the first clamping part, and the first angle fixing part is used to fix the plurality of cameras 80.

[0042] Further, the second camera assembly 30 also includes a plurality of cameras 80, and the plurality of cameras 80 are arranged along the vertical direction on one side of the display 10, and the distance between adjacent cameras 80 is a set value.

[0043] Among them, the camera 80 in the second camera assembly 30 is also an optical positioning camera, and the number thereof can also be multiple. When the number of the cameras 80 in the first camera assembly 20 is two, the number of the cameras 80 in the second camera assembly 30 is also two, and they are arranged along the vertical direction on one side of the display 10 and are also symmetrical about the horizontal axis passing through the midpoint of the display 10.

[0044] The camera 80 in the first camera assembly 20 and the camera 80 in the second camera assembly 30 are symmetrical about the vertical axis passing through the midpoint of the display 10.

[0045] Furthermore, in order to better configure the second camera assembly 30, the second camera assembly 30 further includes a second angle fixing portion and a second clamping portion; the second camera assembly 30 is connected to the connecting rod 40 through the second clamping portion, and the second angle fixing portion is used to fix the multiple cameras 80.

[0046] Furthermore, please refer to Figure 4 For the interaction device stably assembled to the display 10, the interaction device further includes a plurality of equidistant telescopic components 50. The plurality of equidistant telescopic components 50 include telescopic rods 52 and angular clamping structures 51. The angular clamping structures 51 are arranged at the corners of the display 10 so that the equidistant telescopic components 50 are fixedly arranged on the display 10.

[0047] One end of the telescopic rod 52 is connected to the angular clamping structure 51, and the other end is connected to the connecting rod 40 so that the first camera assembly 20 and the second camera assembly 30 remain relatively stationary with respect to the display 10.

[0048] Among them, the number of the equidistant telescopic components 50 can be multiple. Optionally, in the present disclosure, the number of the equidistant telescopic components 50 is 4, which are respectively arranged at the four corners of the display 10. The first camera assembly 20 and the second camera assembly 30 are fixed through the telescopic rods 52 so that the first camera assembly 20 and the second camera assembly 30 remain relatively stationary with respect to the display 10.

[0049] Further, when the interaction device is applied to a 3D computer system, in order to more conveniently connect the interaction device to the computer 90 and ensure that the first camera assembly 20 and the second camera assembly 30 can obtain power and communicate with the computer 90, the interaction device further includes a first constraint assembly 61; the first constraint assembly 61 includes a first wire outlet hole 611 and a first hollow cavity, the first hollow cavity is arranged inside the connecting rod 40, and the wire harness of the first camera assembly 20 is routed along the first hollow cavity and connected to the computer 90 through the first wire outlet hole 611.

[0050] Further, the interaction device further includes a second constraint assembly 62, the second constraint assembly 62 includes a second wire outlet hole 622 and a second hollow cavity, the second hollow cavity is arranged inside the connecting rod 40, and the wire harness of the second camera assembly 30 is routed along the second hollow cavity and connected to the computer 90 through the second wire outlet hole 622.

[0051] Wherein, the connecting rod 40 is hollow, and its internal space can accommodate the first hollow cavity and the second hollow cavity.

[0052] When the interaction device is assembled to the 3D computer system through the first constraint assembly 61 and the second constraint assembly 62, it is ensured that the first camera assembly 20 and the second camera assembly 30 can obtain power and communicate with the computer 90; at the same time, the routing directions of the wire harnesses of the first camera assembly 20 and the second camera assembly 30 can be constrained, meeting the need to protect the precision camera and the precision communication line, and meeting the aesthetic requirements.

[0053] When the user interacts in front of the display 10, increasing the pitch angle of the display 10, at this time the center of gravity of the display 10 shifts, which may cause the display 10 to topple. Further, in order to increase the pitch angle of the display 10 while ensuring that the display 10 is not affected, the interaction device further includes a support column 70, and the support column 70 is connected to the connecting rod 40.

[0054] Wherein, the support column 70 is telescopically adjustable. When the pitch angle of the display 10 needs to be adjusted, a load-bearing fulcrum can be given to the display 10 by adjusting the support column 70, thereby realizing the adjustment of the pitch angle of the display 10. Optionally, in the present disclosure, the adjustment range of the pitch angle of the display 10 is 0 - 180°.

[0055] Wherein, the support column 70 is staggered from the structures of the first constraint assembly 61 and the second constraint assembly 62 and does not interfere with each other.

[0056] After the interaction device is assembled on the display 10, it needs to be calibrated. The calibration parameters include the set value D1 between adjacent cameras 80, the distance D2 between the first camera assembly 20 and the second camera assembly 30, and the center point of the interactive physical coordinate system; the distance D2 between the first camera assembly 20 and the second camera assembly 30 is the length of the connecting rod 40.

[0057] The calibration of the parameters can be performed by 3D interactive parameter calibration software. After the software runs, a two-dimensional coordinate system is drawn on the display 10, with the center point of the screen as the center, the horizontal direction as the X-axis, the vertical line as the Y-axis, and scales are drawn on the coordinate axes according to the scale of the display 10, and the scales are labeled. The positions of the coordinate axes and the coordinate axis scales on the screen are calculated by the software. If the coordinate axis scales calculated by the software are consistent with the actually drawn coordinate axis scales, and the coordinate scales of the corresponding position points of D1 and D2 calculated by the software are consistent with the actually labeled coordinate scales, the calibration process is completed, and the calibrated D1 and D2 are used as constants in 3D stereo interaction.

[0058] Further, please refer to Figure 5 , the calibration process includes the following steps:

[0059] Step S10: Draw a two-dimensional coordinate system on the screen of the display 10 in full-screen mode.

[0060] Step S11: Drag the X-axis in the two-dimensional coordinate system to coincide with the horizontal axis passing through the midpoint of the display 10; drag the Y-axis in the two-dimensional coordinate system to coincide with the vertical passing through the midpoint of the display 10.

[0061] Step S12: Determine whether the coordinate axes have moved in place. If not, return to execute Step S11. If they have moved in place, execute Step S13.

[0062] Step S13: Draw scales on the coordinate axes according to the scale of the display 10 and label the scales.

[0063] Among them, move the interactive pen to the corresponding position points of D1 and D2, including the midpoint position O of the display 10, the intersection points X1 and X2 of the X-axis with the left and right edges of the display 10, and the intersection points Y1 and Y2 with the upper and lower edges, label them, and perform optical positioning sampling.

[0064] Step S14: Determine whether the scales are labeled. If not, return to execute Step S13. If the scales are labeled, execute Step S15.

[0065] Step S15: Calculate the positions of the coordinate axes and the coordinate axis scales on the screen by the software.

[0066] Step S16: Determine whether the axis scales calculated by the software are consistent with the actually drawn axis scales. If they are consistent, execute Step S17; if not, return to execute Step S11.

[0067] Among them, when determining whether the axis scales calculated by the software are consistent with the actually drawn axis scales, it is also necessary to determine whether the coordinate scales of the corresponding position points of D1 and D2 calculated by the software are consistent with the actually marked coordinate scales. If they are consistent, the calibration is completed and Step S17 is executed; if not, return to execute Step S11.

[0068] Step S17: Record the calibrated D1 and D2 in the memory.

[0069] Among them, after calibrating D1 and D2, it is also necessary to calculate the positioning weight parameters of the corresponding position points X1, X2, Y1, Y2, and O thereof and record them in the memory.

[0070] Please refer to Figure 6 , the present disclosure provides a 3D computer system, and the 3D computer system includes a display 10, and the above-mentioned interaction device is assembled on the display 10 so that the 3D computer system realizes 3D stereo interaction.

Please refer to the explanation of the interaction device.

[0072] In summary, the interaction device and the 3D computer system provided by the present disclosure increase the adjustment range of the pitch angle of the display by setting support columns, and ensure that the display does not topple due to excessive pitch angle and center of gravity shift; the first camera assembly and the second camera assembly are respectively arranged on both sides of the display through connecting rods, so that the 3D computer system realizes 3D stereo interaction by adding peripherals, with low cost, and the camera assembly can be replaced and assembled, improving the utilization rate of the camera assembly.
