opencv 显示图片线条粗

要在OpenCV中显示图片线条的粗细，可以使用cv::line函数中的thickness参数来设置线条的宽度。该参数的默认值为1，表示线条的默认粗细。您可以根据需要调整该值来增加或减小线条的粗细。例如，将thickness设置为2或更大的值将使线条变粗。

另外，如果您使用的是Python中的cv2库，可以使用cv2.line函数的thickness参数来设置线条的宽度。同样，您可以根据需要调整该值来改变线条的粗细。

总结起来，要在OpenCV中显示图片线条的粗细，您可以使用相应的绘制线条函数并调整其thickness参数。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
