METHOD FOR DETERMINING CHARACTERISTICS OF A SAMPLE VESSEL IN AN IN-VITRO DIAGNOSTICS SYSTEM, ANALYZING DEVICE, AND IN-VITRO DIAGNOSTICS SYSTEM

摘要

A method is disclosed for determining characteristics of a sample vessel (1) in an in-vitro diagnostics system. The method comprises the steps of, providing first image data representing a first image of a sample vessel (1) in a first scene, wherein in the first scene, a first illumination condition comprising a background illumination of the sample vessel (1) is applied to the sample vessel (1); providing second image data representing a second image of the sample vessel (1) in a second scene, wherein in the second scene, a second illumination condition different from the first illumination condition is applied to the sample vessel (1); determining a mask from the first image, the mask indicating a sub-image section of the first image comprising a representation of the sample vessel (1) in the first image; determining sub-image data from the second image containing a representation of the sample vessel (1) in the second image by applying the mask to the second image; and determining characteristics of the sample vessel (1) from an image data analysis, comprising image data analysis of the sub-image data. Furthermore, an analyzing device (7) having one or more processors configured for carrying out the method, as well as an in-vitro diagnostics system and an in-vitro preanalytical system comprising the analyzing device (7) are provided.
