Scan a Target

Photographing the target

A good photo is the foundation of a reliable analysis. Keep these points in mind:

  • Capture the whole strip — every target must be flat and fully visible.
  • Hold it as straight as possible — avoid strongly tilting or twisting the phone.
  • Avoid shadows — make sure no shadows fall across the target.

Lighting

The right lighting makes the biggest difference in detection.

  • All shots in the black: White light on a white background — just place the target on a sheet of white paper or a bright table.
  • Shots in the outer rings too: White light on a yellow background (e.g. yellow construction paper or card). This makes the white target field stand out clearly as well.
  • Colored backgrounds (orange, red) are also detected reliably.

A sheet of yellow construction paper under the target gives the best results — especially when shots land outside the black aiming mark.

Take or upload a photo

On the Capture page you have several options:

  • “Take photo”: Opens your device camera directly. Point the camera at the strip and take the shot.
  • “From gallery”: Pick an image you’ve already taken from your photo library.
  • “QR code”: Scan a QR code directly with the camera. More on this in Chapter 15 (Import Results).
  • “Import”: Opens the import page for WM-Shot and Meyton files. More on this in Chapter 15 (Import Results).

You can select several images at once — ideal for batch mode, when your series is spread across multiple strips.

Ring Reader capture page

Choosing the target type

Ring Reader supports the following disciplines:

  • Air rifle (10m)
  • Air pistol (10m)
  • 50m smallbore (KK 50m)
  • 50m pistol
  • LG/LP supported (rested shooting)

You can set the target type in two ways:

  • Automatic (default): Ring Reader detects on its own whether it’s an air rifle or air pistol strip. In most cases this works reliably.
  • Manual: If automatic detection doesn’t work, you can set the type yourself before processing.

Automatic detection

In “Automatic” mode, Ring Reader detects the target type from the ring geometry in the photo. Supported:

  • Air rifle 10m (LG)
  • Air pistol 10m (LP)
  • Smallbore 50m (KK)
  • Sport pistol 50m
  • LG/LP supported

If detection fails — for example with poor photo quality or an unusual background — select the target type manually from the dropdown before you start the analysis.

Processing

Tap “Process” to start the analysis. Ring Reader analyzes the image in several steps:

  1. Detect the strip
  2. Find the targets
  3. Detect the configuration (rifle or pistol)
  4. Analyze the shots
  5. Calculate the ring score

A progress bar shows the current status. Once detection succeeds, the app switches automatically to the review screen.

Ring Reader processing

Detecting Meyton printouts automatically

Ring Reader automatically detects whether a photo shows a target strip or a Meyton printout. Meyton printouts are sent automatically for server-side OCR processing — no manual switching needed. Just take a photo and tap “Process”.

Cropped target

If part of the target is cut off in the photo, Ring Reader shows a warning with the option “New photo” or “Continue anyway”.

When detection fails

Sometimes Ring Reader can’t score the strip correctly. In that case:

  • Select the target type manually (rifle or pistol) and try again.
  • You’ll find more tips for better detection in Chapter 13 (Tips & Tricks).
