Optical Symbol Linear Gradient Encoding for Vibration-Resistant Detection

The patent applies color changes by assigning linear gradients to each cell in the two-dimensional code. Each cell contains a gradient that transitions through different colors along a straight line, with the gradient direction and color characteristics encoding information. This allows the code to maintain high information capacity and detection accuracy even with fewer cells, as the gradient patterns provide distinctive visual characteristics that are easier to detect and distinguish under vibration conditions.

The patent changes parameters by introducing linear gradient characteristics to each cell, transforming uniform color cells into cells with directional color transitions. The gradient direction (horizontal, vertical, or diagonal) and the specific color progression become additional encoding dimensions. This parameter enrichment allows the code to convey more information per cell and provides robust detection features that maintain accuracy even when the total cell count is reduced to minimize vibration impact.

The patent introduces another dimension by adding linear gradient directions (horizontal, vertical, diagonal) as an additional encoding layer beyond the basic cell position and color. Each cell's gradient orientation and color progression provide additional information channels, effectively increasing the information capacity per cell without requiring more cells. This dimensional expansion compensates for the reduced cell count while maintaining structural stability against vibration.

The patent enriches the information capacity by changing cell parameters from simple uniform colors to linear gradients with multiple attributes (direction, start color, end color). This parameter transformation allows each cell to encode multiple bits of information through its gradient characteristics, thereby maintaining high information capacity even with a reduced number of cells and improved structural stability.
