Embodiment

[0020] Embodiment: In this interactive display system, the sensor adopts a laser sensor with a 100M Ethernet communication port, which has ultra-high-speed data transmission, collects data 25 times per second, and has 1 measurement data for every 0.36° in each frame of image. Measurement data can be acquired and processed in real time, and more processing or control tasks can be performed. The system consists of figure 1 shown. The system uses a laser sensor to collect target information, and processes the data collected by the sensor through a computer and a serial port monitoring circuit, thereby realizing non-contact multi-point control. Among them, the main components of the interactive display system are as follows:

[0021] Data acquisition subsystem: mainly through the laser sensor to collect the target image in real time, the image represents the distance or the depth of the spatial position information.

[0022] Data processing subsystem: mainly composed of serial ...

Abstract

The invention discloses a filtering method of a non-contact interactive display system. The filtering method is characterized by comprising the following steps: classifying noise generated by a laser scanner in the non-contact interactive display system into longitudinal vibration noise and transverse vibration noise; then filtering the longitudinal vibration noise and the transverse vibration noise respectively. Through combination of transverse filtering and longitudinal filtering, the filtering method greatly reduces influence on human-machine interaction caused by a noise source generated by operational vibration of the motor of a laser sensor, realizes real-time interaction between customers and advertisement contents, enhances product impression and popularity, has excellent advertising effect and entertainment effect, and meanwhile reduces bacterium infection caused by contact owing to non-contact communication so as to be more humanized.

Description

technical field [0001] The invention belongs to the fields of multimedia and human-computer interaction, and in particular relates to a filtering method for a non-contact interactive display system. Background technique [0002] Multimedia technology is the use of computer interactive comprehensive technology and digital communication technology to process media text, images, graphics, video and sound, so that various information can be logically connected and integrated into a human-computer interaction system. Interactive multimedia has stronger real-time interactivity. It is an interactive communication integrating "video, voice, text, and data", which has greatly changed the existing communication methods and is widely used in various exhibition halls, such as: museums, science and technology museums, Enterprise showroom and so on. The interactive multimedia display system has greatly broken through the traditional media communication methods in terms of experience mode...
