Abstract

resumo “reconhecedor de imagem em veículos” um reconhecedor de imagem em veículo que detecta eficazmente um objeto se movendo a partir da imagem mesmo quando as lentes tenham fuligem. em um ajustador de sensibilidade de detecção (50) que ajusta a sensibilidade de detecção a ser aumentada de acordo com o nível de turbidez branca (u), a sensibilidade de detecção de um detector de veículo (70) (unidade de execução de aplicação de reconhecimento de imagem), que detecta outro veículo (6) (objeto que se move) existente na área circundante do veículo (5) com uma sensibilidade de detecção predeterminada a partir da imagem obtida por uma unidade de imagem (10) disposta no veículo (5) para observar a área circundante do veículo (5) através de lentes (12) e converte o sinal de luz da área circundante observada do veículo (5) em um sinal de imagem, é corrigido com base no nível de fixação m da matéria anexada tal como sujeita ou gota de água nas lentes (12), que é calculada por uma calculadora de nível de fixação (26).
