Multimedia exhibition hall interaction method and device based on image detection and storage medium

Abstract

The invention relates to a multimedia exhibition hall interaction method and device based on image detection and a storage medium. The method comprises the following steps: collecting an original image of an interaction area; performing adaptive threshold binarization to obtain a binarized image; subtracting the background to obtain a foreground image; filtering and de-noising the foreground image to obtain a target image; based on the target image, using a contour detection algorithm to obtain a region of interest; judging whether the region of interest is a bright spot or not based on a preset pixel threshold value and a preset area threshold value, and outputting a position coordinate of the bright spot; and if the bright spot is in a specific area, executing an interaction scene corresponding to the specific area. Compared with the prior art, whether the laser irradiates in the specific area or not is detected through image detection, so that the corresponding interaction scene is triggered, a complex sensor circuit does not need to be designed, the position of a bright spot can be judged quickly and accurately, false triggering is avoided, the response speed is high, and the interaction effect is good.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to an image detection-based multimedia exhibition hall interaction method, device and storage medium. Background technique [0002] Today, with the rapid development of multimedia exhibition halls, the diversity of multimedia content display is becoming more and more extensive, and the interaction methods are also becoming more and more diverse. With the development of computer technology and the wide application of multimedia technology, network technology and virtual reality technology, how to integrate various technologies to bring users a better interactive experience has become the focus of multimedia exhibition hall design. [0003] In the design of multimedia exhibition halls, situational design is often carried out around a certain theme. When the user clicks or touches a button, the corresponding scene interaction will be triggered. For example, when the user click...

AI Technical Summary

Problems solved by technology

In the prior art, a sensor is often installed in a specific area to detect whether there is laser irradiation. However, the installation of the sensor will bring a complicated circuit. Setting the sensor in a specific area will affect the visual effect of the area, and the sensor is easily triggered by mistake. Affect the interaction effect
