Abstract

"SISTEMA COMPUTADORIZADO E PROCESSO PARA ESTIMAR A POSTURA DE FORMAS DE SUPERFìCIE UTILIZANDO OPERADORES DE TRIPé". Uma nova técnica conhecida como "remoção de colocação não diferenciadora de postura" é combinada com operadores de tripé (t2ripod o2perators ou TOs) (Figuras 1a-1c), um método para interpretação de imagens de alcance, e é composta por duas etapas. A primeira é o assestamento do sistema em um novo objeto de maneira que seja mais tarde capaz de estimar a postura daquele objeto quando visto novamente em alguma imagem de alcance (Figura 4, 114). A segunda etapa é a estimativa da postura propriamente dita, onde um TO é colocado em um local aleatório numa nova imagem de alcance contendo o objeto de interesse (Figura 5, 102). Então o vizinho mais próximo no espaço característico, o ponto proximal, é computado. Se a distância até o ponto proximal for de menos do que um determinado limite adequado (Figura 5, 108), então a superfície é reconhecida e a estimativa da postura prossegue por meio da computação dos seis parâmetros de postura de um triângulo central da nova colocação no sistema de coordenadas do instrumento para geração de imagem de alcance (Figura 5, 112).
