Obviously, when the information graphics need to be projected in different directions of the physical object, such a fixed interactive area system is not competent; at the same time, when the scale of the physical object exceeds the desktop, or cannot be placed on the table, or moves in a certain area around, such a system The fixed interaction area system is also not up to the task

Embodiment 1

[0051] PTZ( figure 1 ) The upper and lower parts are respectively two rigid members, both of which realize vertical spacing adjustment and rotational positioning around the R-R' axis at the same time with the knob V. The bottom of the lower component adopts the standard camera head size, and is provided with fixing holes for connecting with other fixed or movable supports. The upper part of the lower part is used to connect the 3D scanning equipment. The upper member is connected to the projection device through a horizontal adjustment nut H to realize horizontal translation and direction adjustment. That is to say, during the fixing process of the two devices, the relative positions of the two devices in the horizontal direction, the relative position in the vertical direction, the relative angle in the horizontal direction, and the relative angle in the vertical direction can be changed by adjusting the knobs H and V respectively. Regional adjustment.

Embodiment 2

[0251] Embodiment 1: A compact four-dimensional adjustable pan-tilt is used to adjust the relative position of the projection device and the scanning device.

[0252] Different from Embodiment 1, this embodiment installs the projection device and the three-dimensional scanning device on their respective pan-tilts and sets them in different spatial positions, under the condition that the matching image of the projection can be completely collected by the scanning device , Can also realize the change of the interactive area within a certain space. In this case, the two devices can still use the matching method in Embodiment 1 to quickly complete the matching of the spatial position relationship between the projection device and the scanning device.

Abstract

The invention discloses an interactive-region-adjustable augmented reality realization method. The method is implemented by the following steps of 1, constructing a cloud platform; 2, enabling an interactive region to be adjustable; 3, executing an operation method; and 4, reading and running data for realizing spatial matching. By adjusting four dimensions of a relative spatial position between a three-dimensional scanning device and a projection display device, the adjustment of the augmented reality interactive region and a main information graph projection direction is realized; and the same graph with a non-centrosymmetric relationship pattern, displayed by the projection display device in a full-screen manner is captured twice by use of three-dimensional scanning, and a relative position relationship between the three-dimensional scanning device and the projection display device, and main projection parameters of the display device are calculated through an algorithm. The method has the beneficial effects that after an original augmented reality interaction system is added, the adjustment of the interactive region formed between the three-dimensional scanning device and the projection display device, and the main information graph projection direction is realized, and the application occasion of the original system is extended.

Description

Technical field [0001] The present invention belongs to the field of augmented reality technology. Background technique [0002] At present, there are three-dimensional object interactive systems based on augmented reality technology at home and abroad, such as the CDP system (http: / / cdp.ai.ar.tum.de / ) developed by Gerhard Schubert of the Technical University of Munich, Germany, and Zhang Yina Invented a utility model "A Three-dimensional Model Interactive Demonstration Device" (grant announcement number CN 205281823 U). The operation of this type of system has a similar principle, that is, in each calculation segment that is continuously circulating, the shape of the physical object participating in the interaction is captured in the form of a point cloud through the 3D scanning module, and then it is reconstructed into A geometric object composed of faces, on this basis, the data processing module performs various numerical calculations on it to generate the corresponding two-...
