## Crack Detector Description
Crack Detector is a smartphone app that automatically finds cracks on concrete and other walls based on photos taken by smartphone cameras and measures thickness and length. Analyze photos based on machine learning to find the location of the crack.

When you film a crack with a smartphone's camera, it automatically finds the crack and automatically finds the thickness and length of the crack.

Markers can also be used to measure the thickness and length of the crack in mm.

You can use multiple markers to measure cracks by extracting specific parts of the picture.

You can measure the thickness and length of the crack by printing the marker and attaching it to the screen you want to measure, entering the size of the marker in mm into the setup.
