Abstract

To achieve precise object recognition and quick localization

a driving solution for multi-working modes is designed

aiming to L3Vision electron multiplication CCD image sensor SNR of images is improved by programing-adjustable electron multiplication gain and damping reading noise.Through modifying exposure time

suitable image gray value is acquired to help object recognition

quick localization is realized by raising frame frequency via outputting image of interested areas in open-window mode

the image acquisition system and control system are synchronized by means of synchronize the exposure.Experimental result indicate that clear images can be quickly acquired in low shine environment via the coordinating of diverse solutions.
