Add subpixel_match: sub-pixel template-match refinement#384
Merged
Conversation
Every matcher returns integer coordinates from cv2.minMaxLoc; for a drag handle, fine slider or high-DPI display that rounding is the dominant click-placement error. Fit a parabola to the 3x3 score neighbourhood around the peak (independently on x/y) and return a float cx/cy. Reuses visual_match._score_map.

摘要
新增
match_subpixel/refine_peak— 將比對中心精修到次像素精度。每個比對器都直接從cv2.minMaxLoc回傳整數座標;對拖曳把手、細滑桿、次像素渲染目標或高 DPI 顯示器,整數捨入是主要的點擊落點誤差來源。本功能以拋物線擬合峰值周圍的 3×3 分數鄰域(x/y 各自獨立,標準 NCC 次像素法),回傳浮點cx/cy。重用visual_match._score_map(公開比對器丟棄的完整 matchTemplate 曲面);haystack可注入;Qt-free。五層
utils/subpixel_match/—SubPixelMatch、match_subpixel、refine_peak。AC_match_subpixel/ MCPac_match_subpixel/ Script Builder Match Template (sub-pixel)(Image)。測試
test_subpixel_match_batch.py— 對稱峰偏移 0、右鄰較高→ +x 偏移、定位 + 中心、min_score 過濾、wiring + facade。6 passed。ruff / bandit / radon / float-scan / Qt-free 全乾淨。
