Examples with SelectOverheadParameters boofcv.alg.sfm.overhead.SelectOverheadParameters used on opensource projects

Example 1 with SelectOverheadParameters

use of boofcv.alg.sfm.overhead.SelectOverheadParameters in project BoofCV by lessthanoptimal.

the class ExampleOverheadView method main.

public static void main(String[] args) {
    BufferedImage input = UtilImageIO.loadImage(UtilIO.pathExample("road/left01.png"));
    Planar<GrayU8> imageRGB = ConvertBufferedImage.convertFromPlanar(input, null, true, GrayU8.class);

    CreateSyntheticOverheadView<Planar<GrayU8>> generateOverhead = new CreateSyntheticOverheadViewPL<>(InterpolationType.BILINEAR, 3, GrayU8.class);
    // size of cells in the overhead image in world units
    double cellSize = 0.05;
    // You can use this to automatically select reasonable values for the overhead image
    SelectOverheadParameters selectMapSize = new SelectOverheadParameters(cellSize, 20, 0.5);
    selectMapSize.process(stereoParam.left, groundToLeft);
    int overheadWidth = selectMapSize.getOverheadWidth();
    int overheadHeight = selectMapSize.getOverheadHeight();
    Planar<GrayU8> overheadRGB = new Planar<>(GrayU8.class, overheadWidth, overheadHeight, 3);
    generateOverhead.configure(stereoParam.left, groundToLeft, selectMapSize.getCenterX(), selectMapSize.getCenterY(), cellSize, overheadRGB.width, overheadRGB.height);
    generateOverhead.process(imageRGB, overheadRGB);
    // note that the left/right values are swapped in the overhead image.  This is an artifact of the plane's
    // 2D coordinate system having +y pointing up, while images have +y pointing down.
    BufferedImage output = ConvertBufferedImage.convertTo(overheadRGB, null, true);
    ShowImages.showWindow(input, "Input Image", true);
