Problems solved by technology

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] Gimbal ( figure 1 ) are two rigid components, the upper and lower parts are respectively, and the vertical distance adjustment and the rotation positioning around the RR' axis can be realized simultaneously by the knob V. The bottom of the lower component adopts the size of a standard camera head, and is provided with fixing holes for connecting with other fixed or movable supports. The upper part of the lower component is used for connecting with a three-dimensional scanning device. The upper component is connected to the projection device through the horizontal adjustment nut H to realize lateral translation and direction adjustment. That is to say, during the fixing process of the two devices, by adjusting the knobs H and V respectively, they can realize the change of their horizontal relative position, vertical relative position, relative angle in the horizontal direction, and relative angle in the vertical direction, so as to realize the interaction Regional regu...

Embodiment 2

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

[0252] Different from Embodiment 1, in this embodiment, the projection device and the three-dimensional scanning device are respectively installed on their respective pan-tilts, and arranged in different spatial positions, under the condition that the projected matching image can be completely collected by the scanning device , It can also realize the variable interaction area within a certain space range. In this case, the two devices can still quickly complete the matching of the spatial positional relationship between the projection device and the scanning device through the matching method in Embodiment 1.

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 invention belongs to the technical field of augmented reality. Background technique [0002] At present, there are three-dimensional object interaction 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 in Germany, and Zhang Yina Invented utility model "A 3D Model Interactive Demonstration Device" (announcement number CN 205281823 U). The operation of this type of system has a similar principle, that is, in each calculation segment of the continuous cycle, 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 reconstructed into a shape through the graphics processing module. The geometric object composed of surfaces, on this basis, the data processing module performs various numerical calculations on it to generate correspon...
