Methods and systems for eccentric load error correction are disclosed. A plurality of weighing data sets for a weight having a mass value are obtained, where the weight is loaded at different positions on a weighing platform of a weighing device. Differences between each of the weighing data sets and the average value of the plurality of weighing data sets or the mass value of the weight are calculated. Sensor correction coefficients are calculated and updated when the maximum absolute value of the differences exceeds a pre-set threshold. The weighing data sets are updated. The above steps are repeated until the absolute values of all the differences are less than the pre-set threshold.

Method and system for eccentric load error correction

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 weighing method comprises the steps of: recognizing one or more objects to be detected on a first scale platform top (A) or within an object recognition area of the first scale platform top (A), and weighing the objects to be detected that are placed on a second scale platform top (B). A weighing system comprises at least two scales having scale platform tops utilizing the weighing method outlined above. The weighing method reduces the difficulty of algorithm recognition by increasing the degree to which the object on the weighting platform fits the algorithm, reduces the complexity of operation flow and the time required, and effectively increases the precision and accuracy of object recognition.

A hysteresis compensation method, in which a hysteresis error is calculated for an obtained weighing value by means of an ideal hysteresis error model, and an ideal compensation value is further calculated by means of an ideal hysteresis compensation model, wherein by using a proportional relationship between a system hysteresis error model established in hysteresis calibration and the ideal hysteresis error model, the ideal compensation value is corrected to a final compensation value. The method establishes a mapping relationship between the system's own hysteresis compensation and the ideal state hysteresis compensation, and realizes the transformation of a complicated hysteresis error compensation situation into an ideal hysteresis error compensation situation. The method not only has a good compensation effect for the hysteresis error compensation under ideal situations, but also can obtain an excellent hysteresis compensation effect under complicated hysteresis situations.
