Embodiment 1

[0032] Figures 1A-1B An installation diagram of an object volume measurement system provided by an embodiment of the present invention, the system includes a conveyor belt 11, an image acquisition device 12 and an image processing device 13, and the system also includes: a line laser 14; wherein, the image acquisition device 12 and The line laser 14 is arranged above the conveyor belt 11; the system also includes an L-shaped bracket 15 for fixing the image acquisition device 12 and the line laser 14;

[0033] a line laser 14 for emitting a laser line onto the conveyor belt 11;

[0034] The image acquisition device 12 is used to collect the first picture containing the laser line on the conveyor belt 11 according to the set time interval, and send each first picture collected to the image processing device 13;

[0035] The image processing device 13 is configured to receive each first picture sent by the image acquisition device 12, and determine each first picture by using the ...

Embodiment 2

[0043] In order to improve the accuracy of measuring the height of the object, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the image processing device 13 is specifically configured to perform point-to-point calculation of the first height of the object in each first picture. Cloud denoising, according to each first height of the object after point cloud denoising, determine the target height of the object.

[0044] Specifically, for the first height of the object in each first picture, a preset point cloud denoising algorithm, such as: K-nearest neighbor algorithm, is used to remove the noise points in the first height of the object, and according to the point cloud after denoising For each first height of the object, determine the target height of the object, for example: determine the target height of the object according to the average value of each first height of the denoised object; or determine the target height of the obj...

Embodiment 3

[0046] In order to accurately obtain the height of the object, on the basis of the above embodiments, in the embodiment of the present invention, the image processing device 13 is specifically used to Determine the first height of the object, where h is the first height of the object, u is the distance between the center point of the laser line emitted onto the conveyor belt and the center point of the lens of the image acquisition device, and v is the center point of the lens of the image acquisition device , the distance from the center point of the laser line emitted to the conveyor belt projected onto the image sensor of the image acquisition device, θ is the connecting line between the center point of the laser line emitted on the conveyor belt and the center point of the lens of the image acquisition device , and the angle between the center point of the laser line emitted onto the conveyor belt and the center point of the lens of the image acquisition device, h' is to m...

Abstract

The invention discloses an object volume measuring system and method. The object volume measuring system comprises a conveyor belt, image acquisition equipment, image processing equipment and a line laser; the image acquisition equipment is used for collecting first pictures including pictures of laser rays emitted by the line laser on the conveyor belt at a set time interval, and sending each collected first picture to the image processing equipment; the image processing equipment is used for receiving each first picture, adopting a triangulation telemetry method to determine the first heightof an object in each first picture according to second pictures which are stored in advance and collected by the image acquisition equipment when objects do not exist on the on the conveyor belt yet,and determining a target height of the object according to the first height of the object in each first picture; determining the volume of the object according to the target height of the object andat least one first picture corresponding to the target height of the object. The object volume measuring system and method are used for solving the problem in the prior art that the measured volume ofthe object is inaccurate when the height of the object is not accurately measured.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to an object volume measurement system and method. Background technique [0002] With the rapid development of e-commerce, the volume of online shopping is also increasing rapidly, driving the rapid development of the logistics industry. In the current logistics industry, the volume of objects is related to logistics billing, loading and transportation, and warehouse storage. Obtaining objects volume is required. The existing method for measuring the volume of an object is to set a laser light curtain composed of multiple parallel lasers on the cross section of the conveyor belt. When the object passes through the laser light curtain driven by the conveyor belt, the transmission of the laser below the height of the object will be blocked. , so as to determine the height of the object. And according to the pixel area occupied by the object in the picture of the object collecte...
