如何解决Hstack数组函数,未知回溯错误
对此我很抱歉,但是我完全不知道出什么问题了,所以我只想发布所有内容,时间不长,但是我正在使用一些以前从未使用过的功能,所以我不知道出什么问题了,这似乎是numpy hstack的问题,但是我真的不知道。我知道很多,但是有人可以查看一下我的代码吗?
import numpy as np
import argparse
import cv2
import sys
image = cv2.imread("tetris.png")
virtual_board = cv2.imread("tetris.png")
boundaries = (104,120,164)
boundaries1 = (106,122,166)
for (boundaries) in boundaries:
lower = np.array(boundaries,dtype = "uint8")
upper = np.array(boundaries1,dtype = "uint8")
board_mask = cv2.inRange(image,lower,upper)
output = cv2.bitwise_and(image,image,mask = board_mask)
contours,_ = cv2.findContours(board_mask,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)
print(contours)
contours = sorted(contours,key=lambda x: cv2.contourArea(x),reverse=True)
cnt = contours[0]
(board_x,board_y,board_w,board_h) = cv2.boundingRect(cnt)
cv2.drawContours(image,[cnt],-1,(0,255,0),3)
cv2.drawContours(virtual_board,3)
def ResizeWithAspectRatio(image,width=None,height=None,inter=cv2.INTER_AREA):
dim = None
(h,w) = image.shape[:2]
if width is None and height is None:
return image
if width is None:
r = height / float(h)
dim = (int(w * r),height)
else:
r = width / float(w)
dim = (width,int(h * r))
return cv2.resize(image,dim,interpolation=inter)
resize = ResizeWithAspectRatio(image,width=300)
cv2.imshow("virtual_board",np.hstack([resize,output]))
cv2.waitKey(0)
我得到的错误是:
Traceback (most recent call last):
File "C:\Users\hampus.ramsten\Desktop\Detection.py",line 46,in <module>
