Abstract

ESTIMATIVA DE TAMANHO DE OBJETO USANDO MAPA DE CÂMERA E/OU INFORMAÇÕES DE RADAR. São apresentadas técnicas e sistemas para determinar um ou mais tamanhos de um ou mais objetos. Por exemplo, uma região delimitadora identificando um primeiro objeto detectado em uma imagem pode ser obtida. Um mapa incluindo pontos de mapa também pode ser obtido. Os pontos de mapa correspondem a um ou mais locais de referência em um espaço tridimensional. A região delimitadora que identifica o primeiro objeto pode ser associada a pelo menos um ponto de mapa dos pontos de mapa incluídos no mapa. Usando a região delimitadora e o pelo menos um ponto de mapa, uma posição tridimensional estimada e um tamanho estimado do primeiro objeto detectado na imagem podem ser determinados. Em alguns exemplos, outras informações podem ser usadas para estimar a posição tridimensional estimada e um tamanho estimado do primeiro objeto, tais como informações de radar e/ou outras informações.
