在Java中创建一个图像畸变矫正程序,可以使用Java的`java.awt.image.BufferedImage`和`java.imageio.ImageIO`库,以及开源库如OpenCV (Java版) 或者JHotDraw。以下是一个简单的步骤:
1. **导入库**:
```java
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.core.MatOfPoint2f;
import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.imgproc.Imgproc;
```
2. **加载图片**:
```java
Mat srcImage = Imgcodecs.imread("input.jpg");
BufferedImage src = ImageUtils.matToBufferedImage(srcImage);
```
3. **检测和匹配关键点**:
```java
MatOfPoint2f corners = new MatOfPoint2f();
Imgproc.findChessboardCorners(srcImage, patternSize, corners);
```
4. **畸变矫正**:
```java
Mat dstImage = new Mat();
Imgproc.cornerSubPix(srcImage, corners, new Size(11, 11), new TermCriteria(), cornerAccuracy);
MatOfPoint2f undistortedCorners = new MatOfPoint2f();
Imgproc.initUndistortRectifyMap(cameraMatrix, distCoeffs, R, new Size(srcImage.cols(), srcImage.rows()), dstImage, new Point2f(0, 0));
Core.perspectiveTransform(srcImage, dstImage, undistortedCorners);
```
5. **转换回BufferedImage**:
```java
BufferedImage dst = ImageUtils.matToBufferedImage(dstImage);
```
6. **保存结果**:
```java
try {
File outputFile = new File("output.jpg");
ImageIO.write(dst, "jpg", outputFile);
} catch (IOException e) {
e.printStackTrace();
}
```
这个例子假设你知道相机矩阵 (`cameraMatrix`) 和径向失真系数 (`distCoeffs`),这通常需要通过摄像头标定得到。`patternSize`是棋盘格的大小,`cornerAccuracy`是角点查找的精度,`R`是内参矩阵。
