Abstract

sistemas e métodos para melhorar a cobertura e a eficiência do escaneamento de radar. a presente invenção refere-se a um sistema e métodos para obter o dimensionamento de um objeto de forma irregular. os métodos compreendem: exibir, por uma tela de um sistema de scanner portátil, uma figura óptica 3d de um sujeito; exibir uma grade sobreposta sobre a figura óptica 3d do sujeito, a grade compreendendo uma pluralidade de marcas dispostas em linhas e colunas; gerar, por um módulo de radar do sistema de scanner portátil, dados de alcance especificando um espaçamento detectado entre o módulo de radar e pelo menos uma superfície de uma primeira parte do objeto de forma irregular que é coberta por pelo menos um item; receber, por um processador do sistema de scanner portátil, os dados de alcance a partir do módulo de radar à medida que o sujeito está sendo escaneado; e fazer com que pelo menos uma primeira característica visual de uma primeira marca da dita pluralidade de marcas mude quando os dados de alcance correspondentes são recebidos com sucesso pelo processador.
