Abstract
The study expects to solve the bottleneck problem in the field of intelligent navigation visual sensing and build a network system of information physics, to achieve a visual sensor which can correspond the depth and color of a scene. It aims to improve the robustness and accuracy of color recognition of color structured light in a complex environment. Based on the digital twins (DTs) technology, the effective transformation of logistics process and physical entity to quasi-real-time digital image is realized. The omnidirectional vision sensing technology of a single viewpoint and the panoramic color volume structured light generation technology of a single emission point are integrated. The new active 3D panoramic vision sensor is achieved for which makes the current visual sensing technology developed into the visual perception of body structure. This technology is adopted in the preliminary design of environmental art in the scenic spot, and it can predict the design feasibility of environmental art in the scenic spot, avoid mistakes in decision-making to a great extent and save human and material resources. And also it can analyze and predict some possible dangerous situations, which can greatly improve the environmental safety factor of the scenic spot. In the improvement stage of environmental art design in the scenic spot, using active 3D vision sensing technology can obtain more comprehensive information and is more conducive to the selection of design schemes.
Highlights
Human beings perceive the real world through vision and perceive the depth of space objects from the parallax of two eyes. e ideal visual perception device is a large field of vision sensor that can obtain the scene depth and color map corresponding to the actual space object one by one
The current imaging technology loses the depth information of the space object in the process of obtaining the image. e stereo vision technology in computer vision can enable machines to perceive the stereo information of objects like humans. erefore, the stereo vision has become a research hotspot of computer vision
Based on digital twins (DTs) technology, a new active three-dimensional panoramic vision sensor is realized by combining ODVS with PCSLG, and its architecture and stereo imaging principle is introduced
Summary
With the integration and application of a new generation of information technology (such as cloud computing, Internet of things (IoT), big data, and spatial computing) and industry, countries around the world have issued their own advanced manufacturing development strategies to realize the interconnection and intelligent operation of the industrial physical world and the information world so as to realize the intelligent industry. e Notice on Accelerating the Digital Transformation of State-owned Enterprises issued by the State-owned Assets Supervision and Administration Commission of the State Council in September 2020 clearly pointed out that it is necessary to use 5th generation mobile communication technology (5G), cloud computing, blockchain, artificial intelligence, digital twins (DTs), BeiDou communication, and other new-generation information technologies to explore and build a new IT architecture modes such as “data center” and “business center” to meet the business characteristics and development needs of enterprises and build an agile, efficient, and reusable new generation of digital technology infrastructure. DTs are to create a virtual model of physical entities in a digital way, simulate the behavior of physical entities in the real environment with the help of data. It adds or expands new capabilities for physical entities through virtual and real interactive feedback, data fusion analysis, decision iterative optimization, and other means. With the development of society, visual sensing technology is constantly improving and perfecting, and its role in the environmental art design of scenic spots is changing, but there are still some technical problems to be solved. How to realize intelligent visual perception has become a key technical problem to be solved urgently in China’s social development
