示例1: findRectangle

import org.opencv.core.Core; //导入方法依赖的package包/类
public void findRectangle() {
        Imgproc.cvtColor(originalImage, image, Imgproc.COLOR_BGR2GRAY);
        setFilter();
        this.rects.clear();

        Imgproc.findContours(image, contours, hierarchy, Imgproc.RETR_TREE, Imgproc.CHAIN_APPROX_SIMPLE, new Point(0, 0));

        //For conversion later on
        MatOfPoint2f approxCurve = new MatOfPoint2f();

        //For each contour found
        for (int i = 0; i < contours.size(); i++) {

            //Convert contours from MatOfPoint to MatOfPoint2f
            MatOfPoint2f contour2f = new MatOfPoint2f(contours.get(i).toArray());

                        // Get bounding rect of contour
                        Rect rect = Imgproc.boundingRect(points);

//                        if (Math.abs(rect.height - rect.width) < 1000) {
