Implementing and Using the EMVA1288 Standard

摘要

The European Machine Vision Association took in the last years the initiative of developing a measurement and reporting standard for industrial image sensors and cameras called EMVA1288. Aphesa offers camera and sensors measurement services and test equipment according to this EMVA1288 standard. We have measured cameras of various kinds on our self-made test-equipment. This implementation and all the measurement sets require to go in the details of the standard and also show us how good it can be but also how difficult it can be. The purpose of this paper is to give feedback on the standard, based on our experience of implementers and users. We will see that some measurements are easily reproducible and can easily be implemented while others require more research on hardware, software and procedures and also that the results can sometimes have very little meaning. Our conclusion will be that the EMVA1288 standard is good and well suited for the measurement and characterization of image sensors and cameras for image processing applications but that it is hard for a newcomer to understand the produced data and properly use a test equipment. Developing a complete and compliant test equipment is also a difficult task.
