“…ere are three main types of objects set in Cult3D: scene, action, and event. e scene includes each element in the file and other elements, such as materials, textures, and sounds added later; actions mainly include object movement such as rotation, translation, zooming, selecting camera or perspective switching, coloring materials, and displaying or hiding objects; events are divided into mouse events and keyboard events, scene start events, timers, and custom events for event excitation or browser external events excitation [24]. e interactive design of the Cult3D object is to establish the relationship between events, actions, and scenes in the event map window, so that when the viewer triggers an event or an event occurs automatically, the browser program can control the scene corresponding to the event to make a response.…”

As a special symbolic cultural carrier that reflects people’s material life and spiritual state, jewelry plays an increasingly important role in life. How can we accelerate brand promotion, promote jewelry product sales, and establish a rapid market response mechanism? High efficiency, high quality, and low cost to meet consumers’ increasingly personalized and diversified needs are the problems we currently need to solve. The purpose of this article is to explore the application of VR technology in jewelry displays and provide a brand new idea for jewelry display. In order to realize the virtualization of the jewelry design process, this article uses the Cult 3D VR platform to complete the design and realization of the interactive function of the jewelry virtual model, uses the Photoshop software to design the jewelry virtual display system interface, and finally completes the jewelry virtual display system in the Dreamweaver software integration and release. Through detailed example application, the feasibility of the viewpoint of this subject was effectively verified. In this paper, the two algorithms BRSK and SURF are used in conjunction, and the multiscale expression characteristics of BRISK in space and the rotation-invariant characteristics of SURF are used. Studies have shown that the experimental results of the rotation performance of the method in this paper show that the accuracy is improved by 60%, and the time-consuming is relatively less. Therefore, under the premise of ensuring the rapidity, the method in this paper can guarantee the accuracy and time cost of control matching.

“…In the future research work, we will add the dynamic model of radial rotation in the operation system of surgical catheter robot, and increase the nonlinear influence factors. Combined with the established dynamic model of axial displacement, we will improve the control accuracy and anti-interference ability of the system in remote control [ 24 ]. In addition, more advanced sensors are used to measure the force (contact force and friction force) and displacement information in the system.…”

In the process of artificial interventional therapy, the operation of artificial catheter is not accurate, which will bring strong radiation damage to surgeons. The purpose of this study is to develop a catheter operating system of surgical robot to assist doctors in remote operation and avoid the influence of radiation. BP neural network plays an important role in the flexibility and rapidity of control. According to the actual output of the system, the control parameters of the controller are constantly adjusted to achieve better output effect. This paper introduces the practical application of BP neural network PID controller in the remote operation of the system and compares with the traditional PID controller. The results show that the new control algorithm is feasible and effective. The results show that the synchronization performance of BP neural network PID controller is better than that of traditional PID controller.

In recent years, with the rapid development of virtual reality technology, the visual error correction of continuous aerobics image in virtual environment is of great value to the analysis of Aerobics technology. The main purpose of this paper is to study the visual error correction algorithm of VR image of continuous aerobics. This paper mainly introduces the overview of VR technology, characterist ics and aerobics, some algorithms of visual error correction. This article selects a continuous aerobics coach to take a continuous action of aerobics. These photos were modeled by VR, and the VR images of continuous aerobics were made. The visual error correction of X, y, depth direction of continuous aerobics action VR image with savd algorithm, it algorithm and FT algorithm proposed in this paper are compared, and the VR image performance of savd algorithm and it algorithm is compared. The experimental results show that: the errors of savd algorithm, it algorithm and FT algorithm in X direction, Y direction and depth direction of continuous aerobics action VR image without error correction are reduced by 41%, 26%, 14.16%, 31%, 29%, 21%, 72.7%, 41.1%, 35.1%, respectively. In this paper, the effect of savd algorithm in X direction and depth direction error correction is very obvious, in Y direction error correction has some effect, but not obvious, savd algorithm in continuous aerobics action VR image visual error correction effect is better than it algorithm and FT algorithm. The correctness and feasibility of the proposed savd algorithm for visual error correction of continuous aerobics action VR image is verified.
