OpenCV is one of the most widely used platforms for computer vision. OpenCV has numerous functions for image manipulation and processing as well as integrating it with other platforms. However, many users face errors while installing OpenCV.
This blog will address different ways to fix the error “cv2.error: OpenCV(4.5.2) color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function ‘cv::cvtColor'”.
How To Fix The Error “cv2.error: OpenCV(4.5.2) color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function ‘cv::cvtColor’”?
Please check the image path to resolve this issue. This problem typically occurs when a picture is not loaded properly. The second possibility is that you provided the incorrect image location. Alternatively, try assigning a different path. Third, simply provide the entire path, which may work.
Option 1: Examine image path
Please check the image path to resolve this issue. This problem typically occurs when a picture is not loaded properly.
This is how the error happens.
import cv2 im = cv2.imread("WRONG IMAGE ADDRESS.jpg", 1) im = cv2.cvtColor(im, cv2.COLOR_RGB2GRAY)
// Now we will face this error.
cv2.error: OpenCV(4.5.2) C:\Users\ssc\AppData\Local\Temp\pip-req-build-vi271kac\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function ‘cv::cvtColor’
If possible, provide the picture address directly; for example,
im = cv2.imread(“D:\\your_image.jpg”, 1)
Option 2: Incorrect image location
It’s possible that you provided the incorrect image location. Alternatively, try assigning a different path.
im = cv2.imread(“../images/car.jpg”,1)
Option 3: Provide full path
Simply provide the entire path, which may work.
im = cv2.imread(“D:\My_Image\CANON80D\dang\fvrt.jpg”,1)
