Sewing machine and methods of using the same

A sewing machine, comprising:

• a sewing head attached to an arm suspended above a sewing bed by a pillar;
• a needle bar extending from the sewing head and toward the sewing bed, wherein the needle bar holds a needle;
• a presser bar with a presser foot extending away from the sewing head and toward the sewing bed;
• one or more optical sensors arranged to collect data from one or more features of one or more predefined regions of the sewing machine;
• and
• one or more processors for processing the data collected by the one or more optical sensors, wherein the one or more processors are configured to:
• receive the data from the one or more optical sensors;
• detect and recognize the one or more features of the one or more predetermined regions from the data;
• calculate one or more accuracy indicators of the one or more features from the data as compared to a known feature of the sewing machine;
• compare the value of the one or more accuracy indicators to one or more indicator thresholds;
• and
• adjust a parameter of at least one of the one or more optical sensors based on the comparison between the one or more accuracy indicators and the one or more indicator thresholds.

A method for calibrating one or more optical sensors on a sewing machine, the method comprising:

• collecting data of one or more features of one or more predefined regions of at least one of the sewing machine, the environment surrounding the sewing machine, and the sewing material, wherein the data is collected by at least one of the one or more optical sensors;
• detecting and recognizing the one or more features of the one or more predetermined regions from the data;
• calculating one or more accuracy indicators of the one or more features from the data as compared to one or more known features;
• comparing a value of the one or more accuracy indicators to one or more indicator thresholds;
• and
• adjusting a parameter of at least one of the one or more optical sensors based on the comparison between the one or more accuracy indicators and the one or more indicator thresholds.
