Class ScoreRectifiedViewCoveragePixels

java.lang.Object
boofcv.alg.mvs.ScoreRectifiedViewCoveragePixels
public class ScoreRectifiedViewCoveragePixels extends Object
Scores different views to act as a common view based on coverage of rectified image. It works by using a shrunk down image to compute the area which would be covered by multiple stereo images. An image with more coverage and more images overlaying it is scored higher.

  • Field Details

    • maxSide

      public int maxSide
      Maximum length the largest side can be

    • score

      public double score
      The found area covered score. Computed from fraction of area covered and average count

    • scoreAverageOffset

      public double scoreAverageOffset
      This is used to adjust the influence of average. Larger the value less influence

    • covered

      public double covered
      The actual fraction of the image covered by neighboring views

    • averageValue

      public double averageValue
      Average value of covered pixels

  • Constructor Details

      public ScoreRectifiedViewCoveragePixels()

  • Method Details

    • initialize

      public void initialize(int width, int height, PixelTransform<Point2D_F64> transform_pixel_to_undist)
      Initializes data structures and specifies lens distortion for the target view
      Parameters:
      width - Width of original image in this view
      height - Height of original image in this view
      transform_pixel_to_undist - Lens distortion model from distorted to undistorted pixels

    • addView

      public void addView(int width, int height, DMatrixRMaj rect, float quality3D, boofcv.alg.mvs.ScoreRectifiedViewCoveragePixels.Operation op)
      Adds a view by specifying how target view would be rectified for this stereo pair.
      Parameters:
      width - (Input) Width of the new view being added
      height - (Input) Height of the new view being added
      rect - (Input) Homography from undistorted pixels to rectified pixels in this view.
      quality3D - (Input) Signifies the quality of 3D information available. Higher numbers mean more 3D information from this view. A value of 0 indicates no 3D information. Typically this ranges from 0 to 1.

    • fractionIntersection

      public double fractionIntersection(int width, int height, DMatrixRMaj rect)
      Computes the fraction of the rectified image which is inside the image

    • process

      public void process()
      Processes viewed image and computes a coverage score.
