Material stacking mode estimation method and device based on AR technology

Abstract

The invention discloses a material stacking mode estimation method and device based on AR technology. The method comprises the following steps of 1) determining length, width and height information ofeach cargo needing to be boxed by a user; 2) opening an AR stack presentation interface; 3) constructing a real world three-dimensional coordinate system in the AR stacking presentation interface; 4)obtaining three-dimensional coordinates of three vertexes of the bottom surface of the boxing space under a real world three-dimensional coordinate system; 5) calculating the three-dimensional coordinates of the fourth vertex of the bottom surface of the boxing space and the four vertexes of the top surface of the boxing space under the real world three-dimensional coordinate system; 6) drawing a3D bounding box of the boxing space; 7) obtaining the three-dimensional coordinates of the rear lower vertexes of the left sides of all the cargoes under an algorithm coordinate system, (8) obtainingthe three-dimensional coordinates of the rear lower vertexes of the left sides of all the cargoes under a real world three-dimensional coordinate system, and (9) loading the 3D bounding boxes of allthe cargoes into a boxing space. The method and the device can simulate the boxing process of the virtual cargoes in the real box body.

Description

technical field [0001] The invention belongs to the field of AR technology, and relates to a method and device for estimating material stacking modes based on AR technology. Background technique [0002] Augmented reality aims to register the information to be presented directly into the physical environment. AR transcends mobile computing as it bridges the gap between the virtual and real worlds, both spatially and cognitively. With AR, digital information seems to become part of the real world. Azuma proposed the most widely accepted definition of AR in his survey paper in 1997. AR must have three characteristics: 1. Combination of virtual and reality 2. Real-time interaction with reality 3. 3D registration. This definition does not specify a specific output device, such as a head-mounted reality device (HMD), nor does it limit AR to a specific medium. An AR system needs at least three components: tracking component, registration component, and visualization component. ...

The current design method of setting the scene in the virtual space of the packing software restricts the real participation of software users in the packing process

Since the packing process is in a virtual space, users cannot compare the size of the virtual goods with the size of the real space to be packed, that is, they cannot simulate the packing process of the virtual goods in the real box, which reduces the user experience. Some software cannot support the way of seeing through the internal goods, which may lead to the phenomenon of misloading
