Partial Identity camera trap designs

1 realization of the capture process for 4 camera trapping grids. Single X's are single traps, double X's are double traps. Green guys were captured on both sides at least once during the experiment, yellow guys were only captured on one side at a time, and black guys never captured. Converting double traps to single traps increases uncertainty in ID, but enlarges the grid so that more individuals are available for capture and are captured (n), increasing precision. Hybrid designs balance these two processes. Note double traps are strategically placed to maximize individuals captured on both sides.<br>1. 4个相机诱捕网格（camera trapping grids）的捕获流程实现示例。单个X代表单位点诱捕装置（single trap），双X代表双位点诱捕装置（double trap）。实验过程中，绿色标记的个体至少在网格两侧均被捕获过一次；黄色标记的个体仅在单侧被捕获过；黑色标记的个体则从未被捕获。将双位点诱捕装置转换为单位点诱捕装置会提升个体识别（ID，identification）的不确定性，但可扩大网格覆盖范围，使得更多个体有机会被捕获且实际被捕获的个体数量（n）有所提升，进而提高捕获精度。混合诱捕设计则可平衡这两种效应。请注意，双位点诱捕装置的布设经过策略性规划，以最大化两侧均能捕获到的个体数量。
