Optimal Setting of a Outdoor CCD Camera |

|
| The quality of the images delivered by CCD sensors as well as their linearity with respect to the received light quantity still make them essential for some vision applications. However, their dynamic range is limited with respect to CMOS logarithmic sensors. To avoid this limitation, we propose a software solution allowing to use a CCD camera in outdoor conditions without any auto-iris lens. In this aim, a method to determine the optimum exposure time is proposed as well as a proportional correction rule to control it over time. Once this optimal exposure
is found, we use it to build images with the desired dynamic range by fusing images grabbed at different exposure times. We have thus at our
disposal a solution to grab images with multiple response functions allowing to feed different vision applications. |
