Control device for displaying water curtain images based on black and white pictures

Abstract

The invention discloses a control device for displaying a water curtain image based on a black and white picture. The control device comprises a water drop generator retainer, water drop generators, a water injection pipeline and a computer controller. The water drop generators are arranged on the water drop generator retainer side by side. A water outlet of the water injection pipeline is communicated with water inlets of the water drop generators. Controlled switches of the water drop generators are connected with the computer controller. The number of the water drop generators is the same as that of the subregions which are obtained by segmenting an image to be displayed according to transverse strips and segmenting each strip in the longitudinal direction. The computer controller comprises an image segmentation module and a water curtain imaging control module. The image segmentation module is used for segmenting the black and white picture to be displayed according to transverse strips from the bottom of the picture, and segmenting each strip in the longitudinal direction into subregions. The water curtain imaging control module is used for controlling the state of the controlled switches of the water drop generators by judging the pixel values of the centers of the subregions obtained after each transverse strip is segmented. The control device is low in cost, easy to operate and control, novel in form and good in man-machine interaction.

Description

technical field [0001] The invention relates to water curtain imaging technology, in particular to a control device for displaying water curtain images. Background technique [0002] Most of the existing screen display technologies are displayed in front of viewers in the form of LED lamp beads. In shopping malls, we can see LED large screens playing various patterns and content everywhere. Over time, people's vision gradually becomes fatigued. Different from the musical fountain, the water curtain formed by the musical fountain is an uninterrupted plane from bottom to top, while the water curtain imaging display device enables the water curtain to flow from top to bottom by the gravity of the water itself. Produces gaps, forming a discontinuous image. Water curtain imaging display technology, as a new visual experience, can display simple patterns or subtitles in the form of water droplets in front of people, which will bring a new visual experience to viewers.
