Federated Filter Algorithm with Positioning Technique Based on 3D Sensor

Large‐Screen Interactive Imaging System with Switching Federated Filter Method Based on 3D Sensor

“…The self-developed human-computer interactive positioning software platform system generates an interactive operation interface through a projector on an arbitrary wall or curtain. The Kinect sensor is generally fixed at a range of 1-3 meters directly above the screen and 5-6 centimeters far from the wall surface [4,6,8]. The projector is placed in front of the wall, and the size of the projection surface can be changed by adjusting the distance.…”

“…The definition of human-computer interaction technology is based on a certain software program through the corresponding input and output devices, and the organic combination of computer and human operations is employed to realize the related technology of interactive communication [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The current large-screen human-computer interaction technology is mainly divided into the following categories: (1) infrared frame touch interaction; (2) capacitive touch-based electronic screen touch interaction; (3) speech recognition interaction; (4) computer vision interaction.…”

“…Touch interactions based on infrared frame and capacitive touchbased electronic screens are all based on interactive hardware fixed at a certain place. Therefore, not only are such manmachine interaction operations costly, but also the range and accuracy of the interaction are affected by the hardware constraints [4][5][6][7][8]. Also, interactions based on speech recognition are often limited by complex noisy environments which are mostly used in the small-scale civil-computer interaction field and therefore have a smaller application area.…”

“…The human-machine interaction system based on machine vision is mainly based on sensors and other devices to collect images or signals and then completes the signal preprocessing operations on the image signals collected by the sensors or digital signals through an independently designed humancomputer interaction software. The targets to be tracked are segmented from the background, and a series of operations such as target tracking and motion recognition are used to complete the corresponding human-computer interaction [4,[7][8][9][10][11]. Therefore, the cost of human-computer interaction system designed based on computer vision is relatively low, and the interaction effect can be well obtained.…”

Switching filtering method for interactive systems

“…It is often impossible to obtain an effective filtering effect based on a single filter, and a better precision effect is difficult to obtain. 1–15 There are diversified noises in actual working conditions, and the denoising effect of a single filtering algorithm is not ideal. 16,17 In order to solve such problems, the researchers proposed hybrid filtering algorithms that can improve the accuracy of the system, but it is difficult to guarantee the real-time performance of the system.…”
