Tim Olsen at Atlantic Technologies, a systems integrator, has developed an application to measure the diffusion of nasal spray bottles, using Data Translation's DT Vision Foundry, new machine vision software that combines state-of-the-art vision algorithms with graphical and code level development environments.
This spray analysis application is for a supplier of drug delivery systems, including nasal spray bottles, to pharmaceutical companies.
Spray analysis is normally a subjective, manual process.
The DT Vision Foundry application developed by Olsen allows standardization of the inspection process between the supplier and the pharmaceutical companies who will use their spray bottles.
The nasal spray is sprayed onto an HPLC (high-performance liquid chromatography) plate, and then the plate is scanned using a scanner (this could also be any type of machine vision camera).
The image is then analyzed with the DT Vision Foundry application to see if the diffusion area falls within the specified guidelines.
The application measures the maximum and major distance across the spray pattern as well as the center of axis of the spray.
Olsen used the custom tool development feature of DT Vision Foundry to write a custom tool called Spray Analysis, which he then developed into a full-blown application using the available DLLs (Dynamic Link Libraries).
In addition to the custom Spray Analysis tool, he also employed DT Vision Foundryûs Threshold, Blob Analysis, and Morphology tools, included in the extensive library of vision and image processing tools.
Olsen was able to use all the flexibility of DT Vision Foundry to create the specific application needed to solve the customer's machine vision problem.
DT Vision Foundry, the new machine vision software, is a versatile and extensible package that integrates powerful vision tools with multiple programming environments to provide a robust, flexible, easy-to-use visual inspection package.
DT Vision Foundry is available now.
at a cost of ?3450.00.
