Scanning, Camera
The object scanner works only at night (in darkness) and is calibrated for outdoor use, scanning static large objects such as cars or buildings. When you move the projector, the scan result becomes invalid, and the process has to be repeated from the new position.
- Zoom and focus the projector, secure it in its final position, and tighten the bolts. (already completed in the previous chapter)
- Dim the surrounding lights, dim the building lights, and avoid flashing lights.
- Avoid interfering with the projected light during scanning.
- Avoid movement on the illuminated object.
- Navigate to the projector's main Lumiverse™ menu, click the Power Button in the top-right corner, and switch "Projection" to "Lumiverse on".
- Navigate to Scanner > Scanner
- Here, you can now see scanner controls and the current snapshot from the internal camera.
- The camera view shows the illuminated object photo. If the picture looks all right, don't change the camera profile settings and skip this point. "Camera profile: Auto" works best in most cases. Only if the camera view's image is entirely black or entirely white, click "Refresh". If it's still entirely black or entirely white, try another "Camera profile" and click "Refresh" to update the camera view.
- Two scanner algorithms are available; you can select one. The "Polygons" scanner is quicker, interprets all areas, even low-accuracy ones, but provides lower overall accuracy on complex geometries and edges. The "Pixels" scanner offers precise accuracy and precise edges, leaving low-accuracy areas uninterpreted (black). You can freely experiment with both scanners or even download their results to mix them in Photoshop.
- Find the "Scan algorithm" option, select "Polygons" for quick, edge-free projection surfaces, or select "Pixels" for precise geometry and complex, multi-depth geometries.
- Click "Scan now" to start scanning.
- Scanning takes 7 minutes (Polygons) or 15 minutes (Pixels). Avoid touching the projector and avoid moving or flashing lights in the projected area while scanning.
- Do not close the Lumiverse™ window, and wait for the scanning to complete.
- Review the results: when scanning is complete, Lumiverse™ automatically redirects to Scanner > Results. Here, you can browse the latest scan results, which are named "light" and "dark". Use the left and right arrows and select a better-looking result.
- Click "Download .png" and save the selected scan result to your device.
- You can download the entire scanning history with the "Download Advanced" / "Scanning History" button. A .zip-compressed folder containing all past scans will download to your computer. It contains each scanning attempt in a separate folder. There are two types of images inside: "bg" and "scan". "bg" is not a scan result; it is just a simple photograph. "scan" files are the actual scan results.
- Scanning done. Switch Projection off. (Power Button > Projection > off)
- Troubleshoot 1: If you get poor scan results, try another scan cycle with a different scanner algorithm (Polygons or Pixels available) and compare the results.
- Troubleshoot 2: Try scanning with a different "Camera profile" if the "Auto" default setting doesn't produce recognizable scan results.
- Troubleshoot 3: If the scan result shows a recognizable black-and-white image but lacks texture, you can improve it with the "Daylight Tweak" feature. The purpose of this feature is to add texture to an existing scan result. Unlike when scanning, the "Daylight Tweak" requires external (day)light illuminating the object. Illuminate the object. Navigate to Scanner > Daylight Tweak, click "Apply Daylight Tweak" then wait a few minutes. The projector captures a new image and computes the geometry. After a few minutes, the "daily" labeled result appears in the results.
A valid scan result must be placed in the Editor's background to enable essential Lumiverse™ functions.
- Navigate to Scanner > Results
- Use left and right arrows to select a better-looking scan result.
- Click the "Send to Editor" button: Lumiverse™ will redirect you to the Editor, where you will see the scan result in the background with editor buttons at the top and bottom of the screen.
- Navigate to Settings > Editor Settings, and ensure "Object Transparency" is enabled. With Object Transparency On, objects in the Editor will become semi-transparent, making it easier to see the underlying scan geometry.
Skip if not modifying your scan results.
- Navigate to Settings > Editor Settings > Background Image
- Here, you can delete the current Editor's background (red 'x' button) and upload your file.
You can use the embedded camera to live-view the projection area, which is especially useful when working with the projector from a remote location.
- Tip: You can open two browser windows side by side, use one for the on-site camera stream and the other for editing in Lumiverse™.
- Navigate to Scanner > Scanner. You can see a recent static photograph.
- Click "Show Stream" to start a live stream from the projector's camera.
- Click "Stop Stream" to end the live-stream.
- If the internet is too slow for streaming or you want to save data, you can use a less demanding "auto-Refresh" instead of a live stream. Find the "Camera view" and enable the "auto-Refresh" checkbox to start auto-refreshing the camera view photograph.
- Note: Streaming puts additional load on the projector's CPU and might temporarily reduce playback quality.
