Abstract

localização baseada em imagem. a presente invenção refere-se a um método para localização baseada em imagem que inclui, em um dispositivo de câmera, capturar várias imagens de um ambiente do mundo real. um primeiro conjunto de características de imagem é detectado em uma primeira imagem das várias imagens. antes que conjuntos adicionais de características de imagem sejam detectados em outras imagens das várias imagens, o primeiro conjunto de características de imagem é transmitido para um dispositivo remoto configurado para estimar um posicionamento do dispositivo de câmera baseado em características de imagem detectadas nas várias imagens. conforme os conjuntos adicionais de características de imagem são detectados nas outras imagens das várias imagens, os conjuntos adicionais de características de imagem são transmitidos para o dispositivo remoto. um posicionamento estimado do dispositivo de câmera é recebido a partir do dispositivo remoto.
