摘要:
The method of personal characteristics acquisition especially for biometrical authorization systems, using matrixes of diodes, light focusing and dispersing elements and matrixes of cameras based on the difference of absorption spectra for hemoglobin and other organism tissues, including multibiometrical attitude of one or many biometrical modalities in acquisition process, consists in two stages: in the first one (acquisition level) at least one raw biometrical image is being captured preferably presenting the vascular system, understood as the difference in absorption spectra of hemoglobin and other organism tissues, lightening the object with matrixes of diodes and capturing using matrixes of cameras with filters where in the second stage obtained images are being quality evaluated by one or multithreading procedure preferable using criterial functions evaluating the quality of each of the images if the quality of obtained image, appointed by quality evaluation and / or by the criterial function is above the required value, the image is being under further analysis if the quality of the image, appointed by the criterial functions is below the required value, parameters of matrix of diodes elements are being sequentially changed and / or in a complete way, and operations from the first level are being repeated for new parameterization, where all steps are being repeated automatically creating the mechanism of feedback loop, repeatedly until the required value exceeds the threshold for one of the images during the quality evaluation process.Linvention concerne un procédé dacquisition de caractéristiques personnelles en particulier pour des systèmes dautorisation biométriques, à laide de matrices de diodes, déléments de focalisation et de dispersion de lumière et de matrices de caméras, sur la base de la différence de spectres dabsorption pour lhémoglobine et dautres tissus de lorganisme, comprenant lattitude multi-biométrique dau moins une modalité biométrique dans
