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

[0045] 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 regul...

Embodiment 2

[0243] Embodiment 1: A compact four-dimensional adjustable pan / tilt is used to adjust the relative positions of the projection device and the scanning device.

[0244] 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 provides an interaction-region-adjustable augmented reality pan-tilt system, and provides a pan-tilt system, which enables an interaction region to be adjustable. The system comprises a scanning device, a pan-tilt unit, a projection device, a fixed or movable support, an input unit connected with a three-dimension scanning device, an image and data processing unit, an output unit connected with a projection display device and an augmented reality controller. The input unit connected with the three-dimension scanning device, the image and data processing unit and the output unit connected with the projection display device are arranged in the augmented reality controller; the scanning device and the projection device are arranged on the pan-tilt unit; the pan-tilt unit is arranged on the support; the pan-tilt unit is designed into an upper rigid member and a lower rigid member; the design of the two rigid members realizes change of relative position so as to make the interaction region adjustable; and adjustment of the interaction region formed between the three-dimension scanning device and the projection display device as well as the main information graph projection direction is realized, and an application occasion of an old system is expanded.

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...
