Definitions
- the color separation image is extracted from the mixed image according to the reflection characteristic.
- the LED light emitting devices of different illuminating colors are arranged in the light emitting array at intervals.
- FIG. 8 is a schematic diagram of image acquisition under illumination of different color light sources according to an embodiment of the high speed camera of the present invention
- FIG. 9 is a high speed camera algorithm and process for all camera lenses simultaneously operating under different color LED flashes according to an embodiment of the present invention. diagram;
- the shutter of the present invention is a mechanically controlled, fast-cut mechanical structure; in the case of an electronic shutter, the shutter of the present invention is an electron that controls the accumulation time of the sensor's photo-generated signal charge to control the sensor's light-sensing time. Control module.
- the high speed camera device of FIG. 1 includes two LED light source modules 1, which are disposed on both sides of the photographing module 2. Since the shooting module 2 has a plurality of imaging lenses, a plurality of shooting angles, if a single lighting module is used, it is easy to make partial corner details not sufficiently illuminated. Therefore, a light-emitting module is arranged on both sides of the shooting module to make the light more uniform and the flash has no dead angle.

Abstract
La présente invention se rapporte à un procédé adapté pour prendre une vue à grande vitesse au moyen d'une source de lumière à déclenchement rapide. L'invention se rapporte d'autre part à un dispositif adapté pour la mise en œuvre de ce procédé. Le procédé selon l'invention comprend les étapes suivantes : un dispositif de prise de vue prend en continu une image d'un objet cible ; la source de lumière à déclenchement rapide émet plusieurs rayons lumineux monochromes de différentes couleurs, en séquence, et elle projette les rayons lumineux sur l'objet cible au cours de chacune des périodes d'obturation du dispositif de prise de vue ; le dispositif de prise de vue extrait des images de couleur distincte qui correspondent aux rayons lumineux monochromes de différentes couleurs, à partir des images mixtes ; enfin, le dispositif de prise de vue organise et intègre les images de couleur distincte, dans l'ordre, sur la base d'une durée de projection. La présente invention se rapporte d'autre part à un dispositif de prise de vue à grande vitesse qui utilise une source de lumière à LED. Le dispositif de prise de vue à grande vitesse selon l'invention comprend : un module de prise de vue ; un module de source de lumière à LED ; un module de circuit de commande de déclenchement ; et un module de traitement d'image. L'invention est caractérisée en ce que : le module de prise de vue comprend un objectif de prise de vue, et un capteur de prise de vue qui correspond à l'objectif de prise de vue ; le module de source de lumière à LED comprend plusieurs composants photoémetteurs à LED qui produisent des rayons lumineux de différentes couleurs ; le module de circuit de commande de déclenchement est utilisé pour commander le module de source de lumière à LED et le module de prise de vue ; et le module de traitement d'image est utilisé pour recevoir et traiter des images prises par le module de prise de vue.
