Method and device for providing alopecia information

A scalp measuring device for obtaining scalp images comprising:

• a camera configured to capture a plurality of scalp images;
• and
• an at least one processor configured to select images for analysis to provide hair loss diagnosis assistance information based on the plurality of scalp images;
• wherein the at least one processor is configured to:
• obtain the plurality of scalp images including a first scalp image and a second scalp image;
• obtain pore region information included in each scalp image;
• based on the pore region information of the first scalp image, obtain first quantitative information related to the number of pore regions included in the first scalp image;
• based on the pore region information of the second scalp image, obtain second quantitative information related to the number of pore regions included in the second scalp image;
• and
• select a target image by comparing the first quantitative information and the second quantitative information,
• wherein the at least one processor is configured to obtain initial pore region information related to the pore region included in the scalp image;
• and obtain the pore region information by correcting the initial pore region information,
• wherein the at least one processor is configured to:
• obtain first location information and second location information related to the pore region included in the initial pore region information;
• verify the validity of the first location information and the second location information based on whether the separation distance between the first location information and the second location information is within a predetermined distance;
• and
• determining at least one of first location information and the second location information to be invalid if the separation distance between the first location information and the second location information is within a predetermined distance;
• determining the first location information and the second location information to be valid if the separation distance between the first location information and the second location information is not within the predetermined distance;
• determine a pore region corresponding to the location information determined to be valid as the pore region information when it is determined that at least one of the first location information and the second location information is invalid.
