Abstract (en)
A method is provided for identifying cookware items (30, 32, 34) placed on top of an induction cooktop (10) having a plurality of coils (20<sub>1</sub>-20<sub>n</sub>). The method includes the following steps: acquire coverage factor information for each coil (20<sub>1</sub>-20<sub>n</sub>) and collect it into a matrix; identify all local maxima in the matrix; find the coordinates of each of the local maxima as follows: when the local maxima is a single coil (20<sub>1</sub>-20<sub>n</sub>), the coordinates are those of the coil center, and when the local maxima is a region of contiguous coils (20<sub>1</sub>-20<sub>n</sub>), the coordinates are those of a centroid of the region; calculate distances from each coil (20<sub>1</sub>-20<sub>n</sub>) to each of the coordinates of the identified local maxima; determine a minimum among the distances; classify the coils (20<sub>1</sub>-20<sub>n</sub>) in clusters, based on the distances from the local maxima; and use the identified coil (20<sub>1</sub>-20<sub>n</sub>) clustering to estimate the position, shape, size, and orientation of the cookware items (30, 32, 34).
