There are some disadvantages existing in traditional artificial method of detecting road rut feature, such as consuming
time, consuming energy, low accuracy and danger. In order to solve those problems listed above, a new method of
detecting features automatically based on the laser image processing technology is proposed. The first step is to start
pretreatments such as fuzzy compensating and enhancing the original images. Then adopting an improved watershed
serial segmentation method, we can get binary segmentation images. Used multi-level filtering technology combined
with statistical methods, the accurate road rut feature can be got. It has been proved by experiments that the detection
method has high accuracy and stability.
