Abstract
An apparatus for testing infrared cameras includes: a cover plate which has a plurality of holes formed therethrough and arranged in line in a horizontal direction at a regular interval, the cover plate being adapted to emit an amount of infrared light; and an emission source which is disposed in parallel to and behind the cover plate as viewed from infrared cameras to be tested, the emission source being adapted to emit a different amount of infrared light when compared with the cover plate.
Claims12
An apparatus for testing a pair of infrared cameras configured and arranged to capture stereo infrared images, said apparatus comprising:
- a cover plate which has a plurality of holes formed therethrough and arranged in line in a horizontal direction, said holes spaced apart from one another at a regular interval, the cover plate having a first thermal conductivity and being adapted to emit an amount of infrared light;
- an emission source which is disposed in parallel to and behind the cover plate as viewed from infrared cameras to be tested, the emission source being adapted to emit a different amount of infrared light when compared with the cover plate;
- and
- a pair of spacers disposed between and separating the cover plate and the emission source, said spacers formed from a material having a second thermal conductivity which is lower than that of the cover plate.

- and
- a controller comprising:
- a binary converter for converting gray scale images obtained by said infrared cameras into binary images;
- a calculator for calculating values representing geometric centers of said holes based on said binary images;
- a comparer for comparing the calculated values representing geometric centers of said holes to stored values representing actual centers of said holes;
- and
- a correction factor calculator for calculating a respective correction factor for each of said cameras, based on data generated by said comparer.
