Microwave oven multiview silhouette volume calculation for mass estimation

摘要

A microwave heating apparatus includes a cavity arranged to receive a load. At least one microwave generator is configured to feed a plurality of microwaves into the cavity. At least one image-capturing device and a control unit is adapted to obtain load volume information of the load within the cavity based on information recorded by the image-capturing device about at least one portion of the load, obtain load density information using at least one of a user input and information recorded by the image-capturing device about at least one portion of the load, determine load mass information based upon the load volume information and the load density information, determine a heating pattern based upon the load mass information and control the at least one microwave generator to provide the heating pattern within the cavity.

1. A microwave heating apparatus comprising:
a cavity arranged to receive a load; at least one microwave generator configured to feed a plurality of microwaves into the cavity; at least one image-capturing device; and a control unit adapted to: obtain load volume information of the load within the cavity based on information recorded by the image-capturing device about at least one portion of the load, wherein the control is adapted to convert the information recorded by the image-capturing device into a plurality of two-dimensional silhouette images of the load and combine the plurality of two-dimensional silhouette images of the load to determine the load volume information; obtain load density information using at least one of a user input and information recorded by the image-capturing device about at least one portion of the load; determine load mass information based upon the load volume information and the load density information; determine a heating pattern based upon the load mass information; and control the at least one microwave generator to provide the heating pattern within the cavity.
