带有OpenCV的Java无法读取PNG图像

已解决&为什么：

public class Test

public static void main (String []args)

图像的路径包含Unicode字符，我不得不说这是一个bug

我是OpenCV新手，只需使用java和OpenCV 3.2.0、3.1.0和2.4.3来读取此图像，但没有任何成功，即无法读取宽度或高度，尽管我的目标是查找harris角，而使用其他图像则没有此问题

    Mat img_object = Highgui.imread("E:/ℤIMAGEℂ/ℤtestℂ.png");

图像路径包含Unicode字符

正如有人建议的那样，如果你解决了你的问题，删除它或回答它

若您尝试从Unicode路径读取图像，则会发生错误，并且我并没有看到相关的解决方案，所以您可以阅读此内容

---

遗憾的是，OpenCV的Unicode文件路径存在漏洞。这是OpenCV的问题，但我的问题

错误输出似乎与问题中的代码不一致（没有调用

imshow

）。样本中的路径似乎只包含基本拉丁语——这真的再现了问题吗如果你解决了这个问题，要么写在答案中，要么干脆删除这个问题。@DanMašek，我忘了说，原始文件路径如下所示：“E:/ℤ形象ℂ/ℤ测试ℂ.png”，包含许多Unicode字符，我没有意识到Unicode字符会导致错误，所以我想用一个更简单的代码来问这个问题，并修改了“E:/IMAGE/test.png”的路径，但这会导致提问的误导效果。imshow是一个纯图像显示功能，我忘记了删除控制台文本中的信息。我希望听到你对这个代码的结果。如果你解决了这个问题，那么要么自己回答这个问题（如果你认为它可以帮助其他人），要么删除它it@leonbloy好的，我已经发布了一个答案来解释是什么导致了我的问题。
