将图像从CV_64F转换为CV_8U [英] convert image from CV_64F to CV_8U

问题描述

我想使用OpenCV在Python中将类型CV_64FC1的图像转换为CV_8UC1.

I want to convert an image of type CV_64FC1 to CV_8UC1 in Python using OpenCV.

在C ++中，使用convertTo函数，我们可以使用以下代码段轻松转换图像类型:

In C++, using convertTo function, we can easily convert image type using following code snippet:

image.convertTo(image, CV_8UC1);

我在Internet上进行了搜索，但找不到错误的任何解决方案. Python OpenCV中有任何函数可以将其转换吗?

I have searched on Internet but unable to find any solution without errors. Any function in Python OpenCV to convert this?

推荐答案

您可以将其转换为Numpy数组.

You can convert it to a Numpy array.

import numpy as np

# Convert source image to unsigned 8 bit integer Numpy array
arr = np.uint8(image)

# Width and height
h, w = arr.shape

似乎OpenCV Python API也接受Numpy数组.我还没有测试过.请测试一下，让我知道结果.

It seems OpenCV Python APIs accept Numpy arrays as well. I've not tested it though. Please test it and let me know the result.
