DEVICE, METHOD AND PROGRAM FOR ADJUSTING IMAGING PARAMETER, AND RECORDING MEDIUM

摘要

<P>PROBLEM TO BE SOLVED: To efficiently estimate the number of objects from a time-series image by reducing preliminary calibration work and adjusting a parameter while adapting to an environment of an imaging site. Ž<P>SOLUTION: The device 1 for adjusting an imaging parameter adjusts imaging parameters of one or more cameras 2 in order to measure the number of objects from images acquired by the camera(s) 2. An object extraction processing part 12 detects and extracts object regions from a plurality of images selected from an image data group acquired by the camera(s) 2, and estimates the number of objects in a sample image by integration of load values calculated based on a visual volume calculated from the respective pixels of the extracted object region. A parameter adjustment part 14 selects an optimum imaging parameter from an initial group of the imaging parameters based on an error between the estimated number of objects and the number of objects existing in the sample image acquired from the camera(s) 2. Specifically, an optimum imaging parameter is selected by a genetic algorithm using the error as fitness. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
