J'utilise Qt creator dans Ubuntu 16.04 pour construire un projet non-Qt. J'ai besoin d'utiliser SIFT pour détecter les fonctionnalités. Je sais que SIFT et SURF sont dans OpenCV_contrib donc j'ajoute le module supplémentaire en utilisant Cmake-gui pour configurer OpenCV.OpenCV 3.2.0 ne peut pas accéder à SURF/SIFT dans xfeatures2d
Alors je peux trouver libopencv_xfeatures2d.so/.so.3.2/.so.3.2.0 et libopencv_features2d.so/.so.3.2/.so.3.2.0 aussi dans/usr/local/lib
Quand je suis en utilisant le code de site officiel OpenCV: [EIPD Code de site officiel OpenCV] [1]
pour tester EIPD, je reçois toujours l'erreur
/home/ronjane92/Documents/Qt/OpenCV/build/lib/libslam_essentials.so:-1: error: undefined reference to `cv::xfeatures2d::SIFT::create(int, int, double, double, double)'

Ceci est une question répétée je l'ai donc essayé de Google pour des solutions, mais aucun d'entre eux travaillaient dans ma situation. Quelqu'un qui peut m'aider? Merci.
