hata: 'getRotationMatrix2D' bu kapsamda bildirilmedi

Question

NDK ve OpenCv Stuff konusunda yeniyim. Bazı yerel C++ kodunu derlemeye çalışıyorum.

Ben yerli maddeleri habersiz olduğum gibi error: 'getRotationMatrix2D' was not declared in this scope

bunun dışında bana yardım edin bazı hatayı alıyorum derleme yaparken.

Teşekkürler.

Inline Ben de aynı gibi diğer pek çok hatayı alıyorum yukarıda belirtilen hatadan dışında .Cpp dosya fonksiyon kodu

void RotateImage(const Mat input, Mat &rotated, float angle) 
{ 
    // create the rotation transformation matrix 
    Point2f img_center(input.cols/2.0F, input.rows/2.0F); 
    Mat rot_mat = getRotationMatrix2D(img_center, angle, 1.0); 

    // transform the image 
    warpAffine(input, rotated, rot_mat, input.size()); 
} 

olduğunu.

Derleme sırasında hata günlüğünde satır içi. Zaten varsa

sonra sadece "getRotationMatrix2D" içeren * .hpp dosyaları aramak,

#include "opencv2/imgproc.hpp" 

gibi bir satır eklemek Metin. A Beyan, HairAnalysisUtils.cpp modülünde "getRotationMatrix2D" adında bir varlık tanıtır. Bildiriciye bildirilen varlık için Tanımı belirtmezseniz, bu yüzden sonra bir bağlayıcı hatası alabilirsiniz.
