Title:
METHOD AND APPARATUS FOR DETERMINING VOLUME OF OBJECT
Document Type and Number:
WIPO Patent Application WO/2017/197988
Kind Code:
A1
Abstract:
A method for determining the volume of an object comprises: obtaining a target depth image comprising a target object, acquired by a depth image acquisition device (S101); performing segmentation according to depth data in the target depth image, so as to obtain a target image region corresponding to the target object (S102); determining a target enclosing rectangle that is corresponding to the target image region and that satisfies a preset condition (S103); and determining the volume of the target object according to the target enclosing rectangle and the depth data in the target depth image (S104). Compared with a determining method in which laser is used in the prior art, in the method, a depth image acquisition device is used and a laser measurement device is not needed, so that economic cost is low; in addition, compared with a method in which a manual scale is used in the prior art, in the method, the volume is automatically determined by using a software program without manual operations, so that the method provides a high precision and efficiency; accordingly, the objective of overall consideration of high precision, high efficiency and low economic cost is achieved when the volume of an object is determined in the method. Also provided is an apparatus for determining the volume of an object.
