System and method for dimensioning objects

A computing device for dimensioning an object, comprising: a dimensioning subsystem configured to perform a default dimensioning method and a backup dimensioning method; a memory storing a quality evaluation rule; the processor is connected with the size marking subsystem and the memory, and the processor is configured to control the size marking subsystem to execute the default size marking method so as to obtain default size marking data; comparing a quality metric for the default dimensioning data to a threshold condition defined in the quality evaluation rule; calculating a size of the object based on the default size marking data when the quality metric exceeds the threshold condition; and when the quality metric does not exceed the threshold condition, controlling the dimensioning subsystem to perform the spare dimensioning method to obtain spare dimensioning data and to calculate a size of the object based on the spare dimensioning data. 一种用于尺寸标注对象的计算设备，包括：尺寸标注子系统，该尺寸标注子系统被配置为执行默认尺寸标注方法和备用尺寸标注方法；存储器，该存
