摘要： A method for recognizing markers printed on a learning material, includes sampling an image of the learning material; grouping the sampled image of pixels into a first image group and a second image group based on a threshold; and calculating medians of the first image group and the second image group to update the threshold with a first average value of the calculated medians. Further, the method for recognizing markers printed on the learning material includes repeating the above until a difference between a previous threshold and an updated threshold is equal to or smaller than a reference value; binarizing an image captured by a camera based on the updated threshold; and detecting the markers based on the binary image.

摘要： The present disclosure relates to a grill unit for an air conditioner with a filter main body that filters impurities from air passing through airflow openings and is integrated with the grill unit, and a manufacturing method for the same. In a grill unit for an air conditioner according to the present disclosure, the grill unit defines airflow openings and includes a filter main body formed of a processed filter sheet and inserted and injection molded, and the filter main body includes folds having pluralities of peaks and valleys formed through folding and bending the filter sheet. Also, the folds include a plurality of fold supports provided at a side thereof to continuously support the folds therealong. A method for manufacturing a grill unit for an air conditioner according to the present disclosure includes forming a folded filter main body through folding and bending a filter sheet in operation (a), inserting the folded filter main body in an injection mold for forming the grill unit in operation (b), and integrally forming the filter main body and a filter frame and fold supports that support the filter main body, through injection molding the grill unit in operation (c). Thus, the number of parts and working processes can be reduced, and yield can be increased, to substantially reduce manufacturing costs.
