Diseño, análisis e implementación de un sistema de configuración automático de parámetros de una cámara en soft real time

Abstract

This paper shows the analysis, design and implementation for a system that allows automatic configuration of parameters for a chamber with real time software. This system is based on an API V4L2 video capture for Linux that allows direct communication with the operating system kernel and take advantage of the chamber hardware using threads to execute it's main jobs. Each execution thread is assigned to one processor, therefore decreasing execution and process time. Brightness, contrast and white balance parameters are manually configured for image capturing. The algorithm used for this parameter configuration compares the average value of the image (the sum of the intensity values for each pixel divided by the total pixel) obtained during the execution and a reference image average.
