Augmented reality (AR) enhances the user experience by overlaying digital information onto the real world when viewed through a mobile device. This allows users to easily access technical details that are contextually relevant to the objects they are viewing. Pattern analysis involves scanning and recognizing the user's pattern drawing. The application thoroughly inspects the details of each corner and line to identify any mistakes or errors. It even provides the precise measurements of errors, such as the offset of landmarks, in millimeters.
