Object volume determination method and device

Abstract

The embodiment of the invention provides an object volume determination method and device. The method comprises the steps that a target depth image which is acquired by depth image acquisition equipment and includes a target object is acquired; the corresponding target image area of the target object is obtained through segmentation based on the depth data in the target depth image; the corresponding target external rectangle of the target image area meeting the preset conditions is determined; and the volume of the target object is determined based on the target external rectangle and the depth data in the target depth image. Compared with the determination method through laser in the prior art, the depth image acquisition equipment is adopted without using laser measurement equipment so that the economic cost is low; besides, the volume is automatically determined by the scheme by using the software program without manual cooperation in comparison with the determination method through the manual scale in the prior art, and the precision and the efficiency are high so that the objective of considering high precision, high efficiency and low economic cost in object volume determination can be realized by the scheme.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a method and device for determining the volume of an object. Background technique [0002] As one of the most basic attribute information of objects, volume data is widely used in fields such as production and logistics, especially in volume-based logistics billing and automatic loading of objects. Wherein, the object here refers to a relatively standard cuboid object. [0003] In the prior art, commonly used volume determination methods include a determination method using a laser and a determination method using a manual scale. Among them, although the determination method using laser has high precision, the expensive laser measuring equipment required is low in cost performance, and it is difficult to be widely accepted by users; while the determination method using manual scale requires manual cooperation, and is subject to manual operations and emotions. As a result...
