Automatic characterization of electro-optical sensors with iamge-processing, using the Triangle Orientation Discrimination (TOD) method

摘要

The objective characterization of electro-optical sensors and that of iamge enhancement techniques has always been a difficult task. Up to now the sensor is characterized using the minimum resolvable temperature difference (MRTD) or the minimum resolvable contrast (MRC). The performance of iamge enhancement techniques is done by visual inspection by a human observer. Since in more and more cameras some kind of image processing is applied, a more elaborate test is needed that can measure the performance of the combination of the sensor and the image processing. A good candidate is the TOD (Triangle Orientation Discrimination) method, which is developed as an alternative for MRTD and the MRC methods. We are investigating how the standard TOD-method can be extended to cameras with image processing and whether these measurements can be automated.
