我在這里找到: OpenCV錯誤:內存不足
該findcontours函數可能導致此錯誤,但是在我的情況下,我在代碼開頭聲明了vector> 輪廓 。
錯誤是“內存不足”,因為您沒有足夠的內存...您有內存泄漏。 您正在從磁盤讀取圖像,但從未釋放它們使用的內存。
而且您不應該首先使用IplImage。 這是被Mat(您也使用過)替換的舊格式。 Mat不會發生這種情況,因為它是一個智能指針,並且會釋放自己的內存。
罪魁禍首:
image = cvLoadImage(fileName.c_str(),CV_LOAD_IMAGE_COLOR);
您正在加載3000個IplImages,並且從不釋放它們...
相反,您應該使用c ++ api:
Mat image = imread(fileName,CV_LOAD_IMAGE_COLOR);
