A method of weighing using a scale () comprises the steps of: recognizing at least one of a plurality of objects placed within an object recognition area (A) of a platform () of the scale (), and weighing the plurality of objects placed on the platform () of the scale () to determine a total weight of the plurality of objects. A weighing device () comprises the platform () configured as a plane, and utilizes the aforementioned weighing method. The method of weighing is advantageous in that it reduces the difficulty of object recognition using an algorithm by increasing the degree to which the object on the weighing platform fits the algorithm, reduces the complexity of the operation flow and the time required, and effectively increases the precision and accuracy of object recognition.

Method of weighing using object recognition and device therefor

A platform scale uses a method of detecting a center-of-gravity (COG) offset. A weight value of a load on a weighing platform is calculated. The weighing platform is allowed to reach a steady state. When the weight value exceeds a COG offset threshold, then a position of a load COG is calculated using a load COG position algorithm. Whether the calculated position is in a valid region of the weighing platform is determined. The weight value is displayed if the position is within the valid region; otherwise, the position of the COG is displayed. A display apparatus of the scale displays the weight value or the position of COG of the load. The platform scale alerts a user about a possible invalid weighing event by displaying an image indicative of the COG offset condition, ensuring effective and precise weighing.
