To calculate the area using a camera, you need to fix the camera and calibrate it using the program. Calibration consists of first taking a picture of the background, then placing a square or rectangular object, preferably of the same color, different from the background, and capturing the object - the “capture object” button. Then the area of this object, measured with a tape measure, is entered into the program.
After this, the program is ready to work and will correctly calculate the area of any other object and any shape. The accuracy is very high, and the better the camera and the closer it is to the subject, the more accurate it is. The error is less than 1%. There is no complicated mathematics, the algorithm is very simple, the area is calculated by the number of pixels different from the background, and is calculated through the calibration coefficient.
Such a system can be very useful in many areas where it is necessary to calculate area, for example when cutting various materials (sheets of metal, drywall, wood, etc.).
It will be especially useful for figure cutting or other areas where it is necessary to calculate the area of complex objects that cannot be easily measured with a ruler without complex calculations.
