A. Turn on Show Diameter
1. In the main window, click Settings.
2. Choose the Measurements settings and set the options:
- 1Measurements ➜ the measurement settings.
- 2Show Diameter ➜ select it to measure the diameter of every counted item.
- 3Decimal precision ➜ the number of decimals shown for each diameter (for example, 2 ➜ 35.93).
- 4Diameter calculation is based on ➜ Outer circle (a circle around the whole item, green in the picture) or Inner circle (a circle inside the item, blue in the picture).
3. Click Save.
In the main window, the Adjust panel now shows the Area/Diameter Filter and the Show Diameter switch.
B. Calibrate with a known distance
Before you count, tell the app the real length of something in the photo – for example, the width of the truck or of its rear bumper. The app uses it to turn pixels into centimeters, inches or other units.
1. Click Open and choose the photo.
2. Click Tools and switch on Manual Calibration.
3. A measuring line with two handles and the Measure window appear. Drag the handles to the two ends of the known distance.
- 1Measuring line ➜ drag each handle exactly to one end of the known distance. While you drag, the gray box in the Measure window shows a zoomed view of the handle.
- 2Length and Unit ➜ enter the real length and choose the unit (for example, 260 cm). Distance in pixels shows the length of the line in the photo.
- 3Done ➜ saves the calibration.
For accurate diameters
Take the photo straight in front of the log ends. Choose a known distance that is at the same distance from the camera as the log ends – for example, the rear of the truck when you photograph the load from behind. Calibrate again when the camera distance changes.
C. Count and read the diameters
1. Click Count.
2. Each item shows its diameter in the unit you chose.
- 1Count result ➜ the number of items counted.
- 2Area/Diameter Filter ➜ shows the smallest and the largest diameter in the photo. See Filter items by diameter.
- 3Show Diameter ➜ switch it on to show the diameters on the items, or off to hide them.
D. Filter items by diameter
1. In the Adjust panel, drag the handles of the Area/Diameter Filter to set the smallest and the largest diameter you want to see.
2. Only the items within these limits stay marked. The result shows how many items are within the filter out of the total – for example, 26 / 59.
- 1Area/Diameter Filter ➜ here set from 34.94 to 43.22 cm.
- 2Result ➜ 26 of the 59 logs are within the filter.
3. Click Save to save the result.
E. Sort items by size (optional)
Sorting by size is an extra option. Use it when you want to see at a glance which items are small, medium or large – each item gets the color of its interval.
1. In Settings ➜ Measurements, select Sort detections based on size intervals.
2. Click ADD for each interval and fill in the row:
- 1Sort detections based on size intervals ➜ turns on sorting by size.
- 2ADD ➜ adds a new interval.
- 3Name, Minimum, Maximum and Color ➜ the interval limits, in the unit you use for calibration (for example, cm). Click the trash icon to delete an interval.
- 4Save ➜ saves the settings.
3. Click Count again. Each item now has the color of its size interval.
In this photo the logs between 20 and 35 cm are green (Medium) and the logs between 35 and 60 cm are yellow (Large).
Example: Small 0–20 cm (blue), Medium 20–35 cm (green), Large 35–60 cm (yellow).
