The invention discloses a dual-mode blind guiding auxiliary method and system. The method comprises the following steps: acquiring an environment image; performing pattern recognition processing through the traffic marker recognition model to obtain a pattern recognition result; when the mode identification result is a safe crossing mode, extracting a target crossing image from the environment image; according to the target street-crossing image, calculating a street-crossing distance; according to the street crossing distance, blind guiding assistance is performed through a voice module; or; when the mode recognition result is a safe blind sidewalk mode, extracting a blind sidewalk image to be processed from the environment image; according to the to-be-processed blind sidewalk image, calculating a blind sidewalk obstacle distance; according to the blind sidewalk obstacle distance, blind guiding assistance is carried out through the voice module. According to the invention, environment perception is carried out through image processing, dual-mode blind guiding assistance is realized by identifying a safe street crossing mode or a safe blind sidewalk mode, and the environment perception capability and the navigation capability are improved. The method can be applied to the technical field of visual identification and blind guiding assistance.

    本发明公开了一种双模式导盲辅助方法和系统,方法包括:获取环境图像;通过交通标志物识别模型进行模式识别处理,得到模式识别结果;当模式识别结果为安全过街模式时,从环境图像中提取目标过街图像;根据目标过街图像,计算过街距离;根据过街距离,通过语音模块进行导盲辅助;或者;当模式识别结果为安全盲道模式时,从环境图像中提取待处理盲道图像;根据待处理盲道图像,计算盲道障碍物距离;根据盲道障碍物距离,通过语音模块进行导盲辅助。本发明通过图像处理进行环境感知,并通过识别安全过街模式或安全盲道模式来实现双模式导盲辅助,提高了环境感知能力和导航能力。本发明可应用于视觉识别、导盲辅助技术领域。
