Volume measurement device based on IR map

Abstract

The invention provides a volume measurement device based on an IR image, and the device comprises a depth camera which is used for collecting the point cloud data and the IR image of a target box body; a control module used for determining a side straight line section and a bottom surface of the top surface of the target box body according to the point cloud data; projecting a side edge straight line segment of the top surface into the IR graph to determine a side edge region, and selecting the side edge region in the IR graph; performing straight line detection in the side edge area to generate a plurality of straight lines, merging and screening the plurality of straight lines, determining an edge straight line segment of the top surface, and further determining the length and the width of the top surface; determining the central point of the top surface according to the IR graph, determining the height of the target box body according to the distance from the central point to the bottom surface, and further determining the volume of the target box body; and a display module used for displaying the volume of the target box body. Linear detection is carried out on the side area in the IR graph, the edge linear segment of the top surface is determined, the length, width and height identical to the target are determined, accurate calculation of the volume of the target box body is achieved, and the invention can be applied to the fields of logistics billing and the like.

Description

technical field [0001] The invention relates to volume automatic measurement, in particular to a volume measurement device based on an IR image. Background technique [0002] Volume data, as one of the most basic attribute information of objects, is widely used in fields such as production and logistics, such as logistics billing based on object volume, automatic loading of objects, etc. Wherein, objects in logistics billing or automatic loading of objects often use standard cuboid boxes. Then use the three-dimensional measuring head to automatically, efficiently and accurately calculate the volume of the box to solve the problems of slow manual drawing, cumbersome manual input, incorrect freight calculation, and difficult storage and archiving. [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. [0004] Among them, although the determination method using laser ...

AI Technical Summary

Problems solved by technology

[0004] Among them, although the determination method using laser has high precision, it is difficult to be widely accepted by users due to the low cost performance of assembling expensive laser measuring equipment; while the determination method using manual scale requires manual cooperation and is affected by manual operation and emotions , resulting in neither accuracy nor efficiency being guaranteed
