Automatic identification system from the point of equivalence of volumetric titrations based on computer vision

摘要

The present invention describes a system based on the analysis of image sequences able to automatically identify the equivalence point in a titration process volume.Characterized by the change of colour of the sample of interest. The proposed system is composed of hardware and software.Specifically, the elements of hardware are: (1) an apparatus for volumetric titration, and (2) a computing device to which is connected a camera monitoring.The apparatus of the titration volume is composed of a control module of the titrated volume, as well as a module container of the sample of interest.In turn, the software element consists of an application is responsible for processing and analysis of images of the titration monitored.This application, together with the computing device and the camera monitoring the component module of computer vision system.Based on the computer vision module, the system is able to identify the colour change of the sample of interest and thus determine the equivalence point of the titration.Additionally, the system makes it possible to determine the concentration of an analyte in a solution using a required to do so.As the concentration of the required data, as well as the volume of the sample of interest are provided as input to the system, allowing us to determine the concentration of this sample.Among other advantages of the use of the invention presented in relation to existing technology, has the possibility to use outside of the laboratory environment.Reducing costs of analysis and waste of reagents, low cost, whereas the popularization worldwide microprocessor systems; higher accuracy compared to the titration process for identificAction by the naked eye.
