4. 创建QRCodeDetector对象 接下来,我们需要创建一个QRCodeDetector对象,以便使用其中的方法来检测并解析二维码。在Python中,可以使用以下代码创建QRCodeDetector对象: qr_detector=cv2.QRCodeDetector() 1. 5. 检测并解析二维码 现在,我们可以使用QRCodeDetector对象中的detectAndDecode()方法来检测并解析二维码。该方法...
Is it a UnicodeEncodeError, a UnicodeDecodeError, or some other error (e.g., SyntaxError) that mentions an encoding problem? To solve the problem, you have to understand it first. Coping with UnicodeEncodeError Most non-UTF codecs handle only a small subset of the Unicode characters. When ...
