使用JavaFX显示OpenCV Mat [英] Display OpenCV Mat with JavaFX

问题描述

我想直接用JavaFX显示来自OpenCV的Mat对象.我已经看到可以将Mat对象转换为BufferedImage.但是据我所知，JavaFX无法显示BufferedImage，因此必须进行另一次转换.

I would like to display Mat objects from OpenCV directly with JavaFX. I have seen that it is possible to convert a Mat object into a BufferedImage. But as far as I know you can't display a BufferedImage with JavaFX, so another conversion would have to take place.

是否可以直接 将其转换为JavaFX可显示的数据结构?

Is there a way to directly convert it into a data structure that is displayable by JavaFX?

推荐答案

我发现了将Mat对象转换为JavaFX Image对象的直接方法.

I have found a direct way to convert a Mat object to a JavaFX Image object.

MatOfByte byteMat = new MatOfByte();
Highgui.imencode(".bmp", mat, byteMat);
return new Image(new ByteArrayInputStream(byteMat.toArray()));

您也可以将其编码为.jpg，但.bmp更快.

You can also encode it to .jpg but .bmp is faster.
