Talvez te lembres das palavras introdutórias do início do livro: os ambientes criados pelo homem são predominantemente conjuntos geométricos de formas conhecidas (planos, esferas, cilindros, etc.). Naturalmente, perguntamo-nos se podemos tirar partido desta caraterística, uma vez que ela tem o potencial de beneficiar as tarefas de compreensão de cenas 3D.
E se concebêssemos um sistema capaz de identificar essas formas 3D com precisão? Poderíamos ajudar a automatizar os processos de controlo de qualidade do fabrico, inspeccionando rapidamente os produtos para detetar defeitos. Poderíamos permitir que os veículos autónomos percebessem com precisão o que os rodeia, aumentando a segurança e a eficiência. Poderíamos ajudar a reconstruir artefactos antigos para simulações arqueológicas.
Dotar as máquinas de capacidades de reconhecimento de formas 3D permite-lhes perceber e interagir com o mundo físico. Numa primeira fase, ajuda a compreender o ambiente. Ao reconhecer objectos e as suas relações espaciais, os sistemas podem navegar em ambientes complexos e tomar decisões informadas.
Além disso, o reconhecimento de formas 3D permite que as máquinas executem tarefas de forma autónoma. Os sistemas automatizados podem executar funções como a manipulação de objectos, a montagem e a inspeção com uma precisão e eficiência notáveis. ...
