Este artigo descreve um esquema para capturar uma imagem ampla usando uma configuração de câmera com câmeras não calibradas. A configuração é tal que os eixos ópticos apontam em direções divergentes. A direção de visão da imagem resultante pode ser escolhida livremente em qualquer direção entre esses dois eixos ópticos. O esquema usa transformações de perspectiva de oito parâmetros para distorcer as imagens, cujos parâmetros são obtidos usando um algoritmo de orientação relativa. A distância focal e o fator de escala das duas imagens são estimados usando a técnica de otimização multidimensional de Powell. Experimentos em imagens reais mostram a precisão do esquema.

Abstract: This paper describes a scheme to capture a wide-view image using a camera setup with uncalibrated cameras. The setup is such that the optical axes are pointed in divergent directions. The direction of view of the resulting image can be chosen freely in any direction between these two optical axes. The scheme uses eight-parameter perspective transformations to warp the images, the parameters of which are obtained by using a relative orientation algorithm. The focal length and scale factor of the two images are estimated by using Powell's multi-dimensional optimization technique. Experiments on real images show the accuracy of the scheme.
