关于#obr与flann#的问题，如何解决？

问题遇到的现象和发生背景

obr与flann一起使用报错

问题相关代码，请勿粘贴截图

import cv2
import numpy as np

#读两个文件
img1=cv2.imread('math/opencv_search.jpg')
img2=cv2.imread('math/opencv_orig.jpg')

#灰度化
g1=cv2.cvtColor(img1,cv2.COLOR_BGR2GRAY)
g2=cv2.cvtColor(img2,cv2.COLOR_BGR2GRAY)

#建立特征检测器
orb=cv2.ORB_create()

#计算描述子与特征点
kp1,des1=orb.detectAndCompute(g1,None)
kp2,des2=orb.detectAndCompute(g2,None)

#创建匹配器
index_params=dict(algorithm=1,trees=5)
search_params=dict(checks=50)
flann=cv2.FlannBasedMatcher(index_params,search_params)

#对描述子进行匹配计算
matches = flann.knnMatch(np.asarray(des1, np.float32), np.asarray(des2, np.float32), k=2)

good=[]
for i,(m,n) in enumerate(matches):
if m.distance<0.7*n.distance:
good.append(m)

ret=cv2.drawMatches(img1,kp1,img2,kp2,[good],None)

cv2.imshow('img3',ret)
cv2.waitKey(0)

运行结果及报错内容

cv2.error: OpenCV(4.6.0) :-1: error: (-5:Bad argument) in function 'drawMatches'

Overload resolution failed:

• Can't parse 'matches1to2'. Sequence item with index 0 has a wrong type
• Can't parse 'matches1to2'. Sequence item with index 0 has a wrong type
• drawMatches() missing required argument 'matchesThickness' (pos 7)
• drawMatches() missing required argument 'matchesThickness' (pos 7)

我的解答思路和尝试过的方法

把int改成float

我想要达到的结果

可以正常使用

ret=cv2.drawMatches(img1,kp1,img2,kp2,[good],None) 你这里边的参数是不是写反了，kp1和kp2
