Dynamic grass color scale display technique based on grass length for green landscape-friendly animation display

Area of Science:

• Environmental Science
• Display Technology
• Urban Planning

Background:

• Public displays in urban green spaces often detract from natural aesthetics.
• Previous grass animation displays used subjective color mapping, leading to inaccurate color representation.
• There is a need for landscape-friendly display technologies that integrate with natural environments.

Purpose of the Study:

• To develop an objective grass color scale setting procedure for grass animation displays.
• To dynamically control grass color based on grass length for improved visual accuracy.
• To enhance the integration of digital displays within urban green landscapes.

Main Methods:

• Developed a procedure to map grass length to a five-level color scale using image processing.
• Utilized an outdoor experiment to validate the color scale's correspondence to grass length from a viewer's perspective.
• Implemented a grass animation display system incorporating the dynamic color scale.

Main Results:

• Successfully established an objective mapping between grass length and a five-level color scale.
• Demonstrated that the color scale accurately represents grass length based on visual perception in outdoor settings.
• Validated the grass animation display's capability to show animations with the objectively determined color scale.

Conclusions:

• The dynamic grass color scale display technique provides an objective and visually accurate method for landscape-friendly displays.
• This technology offers a significant improvement over subjective color mapping in previous systems.
• The developed method enhances the aesthetic integration of digital displays in urban green spaces.
