自製棋盤格標定板 單目相機標定

單目相機標定方法可以選用matlab，ros，opencv等。對於非專門標定人員，了解其基本原理就可是實踐了，不需深究細究其公式解法 至少還是要看的懂 畢竟這是一門工程活。本文分別使用 opencv 和 kalibr 對某款手機的相機進行標定。官方教程如下 create calibration pa...

OpenCV4 0開啟指定USB攝像頭問題

網上查了些資料，試圖通過usb攝像頭名稱獲取index，從而開啟指定攝像頭，如下 std vectorlist listdevices list for int i 0 i編譯通過後挺好使，誰知第二天重新開機，竟然開啟的是另外的usb攝像頭！追蹤半天沒發現異常，只能得出結論是listdevice得到...
