Cada m\u00e9todo capta tipos de dados diferentes.<\/p>\n<h3>Digitaliza\u00e7\u00e3o laser 2D<\/h3>\n<p>Uma <strong>digitaliza\u00e7\u00e3o laser 2D<\/strong> regista medi\u00e7\u00f5es num \u00fanico plano. Daqui resulta um mapa plano, um esquema de disposi\u00e7\u00e3o ou uma planta.<\/p>\n<p>A digitaliza\u00e7\u00e3o 2D \u00e9 ideal para contornos de divis\u00f5es, plantas, \u00e2ngulos de paredes e esquemas simples. \u00c9 tamb\u00e9m mais r\u00e1pida e mais f\u00e1cil de processar do que a digitaliza\u00e7\u00e3o 3D.<\/p>\n<h3>Digitaliza\u00e7\u00e3o laser 3D<\/h3>\n<p>Uma <strong>digitaliza\u00e7\u00e3o laser 3D<\/strong> recolhe medi\u00e7\u00f5es a partir de muitos \u00e2ngulos e profundidades.

Por isso, \u00e9 \u00fatil para projetos complexos que exigem modelos 3D detalhados.<\/p>\n<p>No entanto, a digitaliza\u00e7\u00e3o 3D gera muitas vezes ficheiros de grandes dimens\u00f5es. Pode tamb\u00e9m exigir mais tempo, software e p\u00f3s-processamento.<\/p>\n<h2>Porque \u00e9 que muitos profissionais preferem a digitaliza\u00e7\u00e3o 2D<\/h2>\n<p>Muitos profissionais t\u00e9cnicos n\u00e3o precisam de um modelo 3D completo em todos os projetos. Em muitos casos, uma planta 2D clara e precisa \u00e9 suficiente.<\/p>\n<p>Arquitetos, engenheiros civis, top\u00f3grafos e carpinteiros precisam muitas vezes de representa\u00e7\u00f5es planas e simples dos espa\u00e7os. Estas incluem plantas, plantas de implanta\u00e7\u00e3o e medi\u00e7\u00f5es de interiores.<\/p>\n<p>Para estas tarefas, a <strong>digitaliza\u00e7\u00e3o 2D<\/strong> \u00e9 normalmente mais r\u00e1pida e mais econ\u00f3mica. Evita tamb\u00e9m a complexidade de uma digitaliza\u00e7\u00e3o 3D completa.<\/p>\n<p>Assim, os profissionais podem recolher os dados essenciais de que precisam sem processamento pesado nem pormenores desnecess\u00e1rios.<\/p>\n<h2>A lacuna nos instrumentos de digitaliza\u00e7\u00e3o 2D<\/h2>\n<p>Embora a digitaliza\u00e7\u00e3o 3D tenha evolu\u00eddo rapidamente, nem sempre \u00e9 f\u00e1cil encontrar instrumentos adequados de digitaliza\u00e7\u00e3o 2D. O setor tem-se concentrado sobretudo nos sistemas 3D.<\/p>\n<p>Isto deixou uma lacuna para os profissionais que precisam de instrumentos de medi\u00e7\u00e3o 2D simples e precisos. Muitos utilizadores continuam a recorrer a fitas m\u00e9tricas, medidores laser 1D e esbo\u00e7os \u00e0 m\u00e3o.<\/p>\n<p>No entanto, estes m\u00e9todos podem originar erros e novas visitas \u00e0 obra.
