  • Page 27: Warping Algorithms

    6 Geometry correction Image Geometry Correction (often referred to as Image Warping) is the process of digitally manipulating image data so that the image’s projection precisely matches a specific projection surface or shape. Image Geometry Correction compensates for the distortion created by off-axis projection or screen placement or non-flat screen surfaces by applying a compensating inverse distortion to the image in the digital domain.

  • Page 28: Warping User Interface

    6.2 Warping user interface To apply warping to an image, select “Warp” from the left hand toolbar. The window in Figure 6-1 will appear. Figure 6-1. Warping algorithm setup Algorithms can be added or removed. If the perspective transform is added first, Mesh Warp Transform can be used in addition.

  • Page 29: Scaling Filters

    6.3 Scaling filters Regardless of the warping algorithms selected, a scaling filter will be applied. Scaling filters are configured using the Algorithm Setup window. Select the tab “Filter”, Figure 6-2, and select your desired filter. Four different scaling filters are supported: • Lanczos, B-spline, C-spline, Linear Figure 6-2.

  • Page 35: Edge Blending Algorithms

    7 Edge blending 7.1 Introduction Edge Blending is a companion feature to Image Geometry Correction. Edge Blending ena- bles the seamless projection of a large image using several overlapping projectors. Since geometry correction for projection on non-flat surfaces is a built-in requirement in almost all Edge Blending systems, the pairing of Edge Blending and Image Geometry Correction in the same video signal processor is a natural one.
  • Page 36 Figure 7-1. Basic edge blending. In the Basic Blend setup window, overlapping pixels (or percent) can be specified. The blend drop-off curve of can also be tuned. Tuning the blend drop off curve is also possible when the unit is in Online state, for a visual fine tuning of the curve. Multi image processor User’s Guide –...

  • Page 41: Test Patterns

    8 Test patterns The multi image processor has several built-in test patterns for easier setup. This tool can be used to tune the geometry (warping) in a setup to match reference points, aspect ratio, ensure visual correctness and to configure 3D image generators for shapes like cylinders and domes.

  • Page 42: Circle Test Pattern

    8.1 Circle test pattern Circles can be added to calibration area to ease the setup. The position (x, y pixel coordinates) and the radius (pixels) can be specified. Figure 8-3 shows the Test Image Setup window with two circles added. Figure 8-3.

  • Page 43: Grid (Pixel) Test Pattern

    8.2 Grid (Pixel) test pattern A grid with much smaller cells than the calibration grid can be really convenient for setup. Especially when using the Mesh Bezier Warp where the calibration can be done with very few control point. To add a Grid (Pixel) select the “Grid (Pixel)” tab and specify your parameters (). The parameters are: offset (x, y in pixels for top, left corner) and height and width of the cells in the grid.

  • Page 44: Grid (Angle) Test Pattern

    8.3 Grid (Angle) test pattern The last test pattern available in the processor unit is the Grid (Angle) test pattern. This is used to create a reference grid in a dome or a cylinder. Parameters to specify for this grid are ‘to’ and ‘from’ angles (in degrees) in horizontal and vertical direction.
