Cooking apparatus and control method thereof

A control method of a cooking apparatus including a cooking chamber in which a food material is to be placed, a heating portion configured to heat an inside of the cooking chamber, the heating portion including a plurality of heaters and a plurality of motors which transmit a rotational force corresponding to each heater among the plurality of heaters, a temperature sensor disposed inside the cooking chamber, a three-dimensional (3D) sensor configured to detect a 3D shape of the food material, and an imager configured to obtain an image of the food material by imaging the inside of the cooking chamber, the control method comprising:

• determining conditions including a target rate of an internal temperature rise of the food material and a target reach internal temperature of the food material, based on a type and a size of the food material;
• and
• adjusting an output of the heating portion based on the conditions and an internal temperature of the food material determined based on a temperature of the food material detected by the temperature sensor,
• wherein the adjusting the output of the heating portion includes:
• when a plurality of food materials are placed in the cooking chamber, determining one or more areas, in which each food material among the plurality of food materials is placed, based on the 3D shape of each food material detected by the 3D sensor and an image of each food material among the plurality of food materials obtained by the imager, and
• controlling the plurality of motors to rotate the plurality of heaters to allow the one or more areas, in which each food material among the plurality of food materials is placed, to be included in a heating area heated by one or more of the plurality of heaters.
