Method and device for obtaining volumes of target objects, terminal equipment and storage medium

Abstract

The invention relates to a method and device for obtaining volumes of target objects, terminal equipment and a computer readable storage medium. The method comprises the following steps of: receivingdepth image data, shot by a depth camera, of a target object on a planar platform; converting the depth image data into first point cloud data; segmenting a planar platform point cloud from the firstpoint cloud data so as to obtain a datum plane; clustering the residual point cloud data after the segmentation so as to select second point cloud data associated with a maximum clustering body from the residual point cloud data to serve as a target object point cloud; obtaining height data of a target object; obtaining a planar projection point cloud, on the datum plane, of the target object point cloud; obtaining length and width data of the target object through calculating a minimum area surrounding rectangle of the planar projection point cloud; and calculating a volume of the target object on the basis of the height data and the length and width data. When being used for measuring volumes of target objects, the method and device have the advantages of being rapid, correct, convenientto use and low in cost.

Description

technical field [0001] The present invention relates to three-dimensional measurement technology, and more specifically, to a method and device for acquiring the volume of a target object based on a depth image, a terminal device, and a computer-readable storage medium. Background technique [0002] Structure Light technology calculates the position and depth information of objects through laser refraction and algorithms, and then restores the entire three-dimensional space. Representative products of structured light include Microsoft Kinect. By emitting speckle or dot matrix laser infrared patterns of a specific pattern, when the measured object reflects these patterns, the reflected pattern (ie depth image) is captured by the camera, and the size of the speckle or point in the depth image is calculated, followed by The size of the original speckle or point is compared, so that the distance between the measured object and the camera can be calculated. When the distance b...
