Water-absorbent labels

Abstract

This item is a mark used for orientation during three-dimensional photo measurement, and is intended to be placed on the ground in a field where agricultural crops are grown. The item is made of a sponge-like absorbent material to prevent water droplets from remaining on the surface. Furthermore, to prevent mud from adhering to the top surface, the main body of the item is not flat or sheet-shaped, but has a three-dimensional shape with thickness in the height direction. Furthermore, the item has an identification mark on the top surface to allow identification from captured images. To improve visibility and automate work, the color of the side of the item can be changed depending on the size of the item's thickness in the height direction.
