opencv报错，在做图像的匹配中出现outimage函数报错情况，具体在帖内

error: OpenCV(4.5.2) :-1: error: (-5:Bad argument) in function 'drawKeypoints'> Overload resolution failed:> - Expected cv::KeyPoint for argument 'keypoints'> - Expected cv::KeyPoint for argument 'keypoints'
以上为报错情况

----------------------------------------------------------------------------------------------------------------
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
img = cv2.drawKeypoints(imagre1,imagre,None,color=(255,0,255))
dest = cv2.drawMatchesKnn(imagre1,imagre,None,flags=2)
以上为使用的代码

-----------------------------------------------------------------------------------------------------------------
如果将none替换为outimage会出现查询不到outimage函数的报错
如图

报name 'outimage' is not defined时使用的代码为

img = cv2.drawKeypoints(imagre1,imagre,outImage,color=(255,0,255))

代码贴完整，看着报错只能知道说你的outputimg未定义，而且你的keypoints参数在哪里？你怎么拿到的？你确定你的image是keypoints？
