Description:VisualRuler is FREE for limited time
Need to measure the size of the object but do not have a ruler? VisualRuler calculates the size of objects in the image using computer vision techniques . You will need to use a card as a reference object. Everything is done offline on your phone.
Because all cards (credit card, library card, public transport card, ID card...) have unified side lengths they can be used as a reference rectangle to calculate sizes of objects in the plane.
HOW TO USE
1.) Take a picture of an object you want to measure next to any card
2.) VisualRuler will automatically detect the card. If you don't like the detection result you can readjust the reference rectangle.
3.) Add lines or rectangles around objects you want to measure.
4.) Export the result image or share on social networks.
PRIVACY
We take privacy concerns serious, especially if you use your credit card or other cards with sensitive information. The picture you take will not be uploaded anywhere to the internet without your knowing.
