Problems solved by technology

[0004] A disadvantage associated with this analysis technique is that imaging devices only record the shape and area of ​​particles in two dimensions (2-D), and are therefore best suited for homogeneous objects or spheres
However, when analyzing inhomogeneous objects, the third dimension of particles (orthogonal to the imaging plane) will remain somewhat unknown by using this existing equipment

Embodiment Construction

[0010] 3-D imaging can be performed by a mechanism as shown in FIG. 1 .

[0011] Here, the sample is injected into a funnel 1 . The sample is then fed through the vibrating plate 2 and falls off the edge 3 of the plate. Rotation is due to gravity and partial support on the feeder plate, and also due to movement of the vibrating feeder. The rotation begins when the object slides off the feeder plate.

[0012] The object in the sample is then dropped and rotated into the measurement space where the imaging system 4 captures a plurality of images of the object in the sample. Typically, each single object is captured multiple times as indicated by the numbers on the left, which identify instances in which one of the falling objects was captured.

[0013] There can be multiple objects of different shapes and sizes in each image.

[0014] The object is captured by using a high-speed imaging system with a high-speed imaging system high enough to give multiple images (2 or more im...

Abstract

A method and an apparatus for analysing at least one object, comprising at least one means for capturing images of said at least one object and means for generating a relative mutual movement between said at least one image capturing means and said at least one object, and further comprising means for processing and analysing images captured by the image capturing means. The relative mutual movement involves a mutual rotational movement between said at least one object and said image capturing means, thus establishing two or more images of said object(s) at various angular positions relative the image capturing means for further processing and analysis in a computer based image analyser.

Description

technical field [0001] The invention relates to a method and a device for analyzing objects. More specifically, the present invention relates to the analysis of objects contained in a flow or product sample, where data as individual object size and shape as well as public data as size distributions, etc. can be calculated and monitored. Background technique [0002] One embodiment of the stream of objects, which may be a succession of objects, is to form essentially a single layer or curtain in which the objects are captured by the image processing unit. [0003] An automatic particle analysis method and a device for carrying out the method are known from EP0348469B1, in which the size distribution of objects and the deviation of the particles from a desired shape and desired color can be determined. A sample of the particles flows out of the silo and onto the vibrating plate, creating a flowing curtain of monolayer objects. The particles are allowed to fall over the edge ...
