Provided are a multi-image acquisition apparatus and a movable system for automatically detecting a road condition using the same, which can accurately detect the conditions of the road by classifying the road conditions into five stages of dryness, wetting, hydroplaning, snowfall, and freezing by obtaining a horizontally polarized image, a vertically polarized image, a 45-degree diagonally polarized image, and an original image which is not polarized at the same time; can monitor the road conditions of a wider area by utilizing a probe car to measure a unit road condition of each road section by expanding to a visual area; and can be utilized even under low light level conditions at night by easily reflecting texture characteristics during the image processing.(110) Vehicle outside sensor(111) Contactless temperature sensor(112) Humidity sensor(130) Sensor information collecting module(140) GPS module (external type)(150) Multi-image acquisition apparatus(160) Image processing module(170) Power supply device(200) Inside of a vehicle (probe car)(AA) Outside temperature information(BB) Vehicle speed information(CC) Road surface temperature information(DD) Collection of four images (0-degree, 90-degree and 45-degree polarized images and an original image)(EE, JJ) GPS data(FF) Road surface image information(GG) Road surface temperature information(HH) Outside temperature information(II) Vehicle speed information(KK) Acceleration sensor information(LL, NN) Humidity information(MM) Divide and discriminate road surface condition into dryness, wetting, hydroplaning, snowfall, and freezingCOPYRIGHT KIPO 2014
