Device for Measuring Visibility for Fog Guardian Device

摘要

The present invention relates to a visible range measuring device for a fog damage prevention apparatus. More specifically, the visible range measuring device captures the movement of a vehicle running on a road as images to measure the visible range on a real-time basis. According to an embodiment of the present invention, the visible range measuring device includes: a communication unit (10); an image processing unit (20); a control unit (30); a display unit (50); and a brightness measuring unit (60). The image processing unit (20) executes a difference operation to obtain difference images between an initial image frame and subsequent consecutive image frames among multiple image frames that are input from the communication unit (10) for a predetermined period.
