Abstract

"MAPEAMENTO E CALIBRAGEM DE PONTA DE CANETA CâMARA". As posições x-y da ponta de uma caneta digital podem ser determinadas por se utilizar um parâmetro de calibragem para mapear as posições x-y dos respectivos centros das imagens capturadas pela câmara da caneta. O parâmetro de calibragem pode ser gerado por repetidamente calcular estimativas do parâmetro de calibragem. Os dados de calibragem de entrada podem ser produzidos por um usuário colocando a ponta da caneta em uma localização fixa em uma superfície, a qual pode ser um meio posicionalmente codificado, tal como papel e então, girar a caneta e/ou mover a extremidade oposta da caneta em várias direções para capturar múltiplas imagens para uso ao gerar o parâmetro de calibragem. Um usuário pode executar tal procedimento de calibragem sem a necessidade de equipamento de calibragem complicado tipicamente utilizado em conexão com as técnicas de calibragem convencionais.
