PURPOSE: An environmental adaptation type pedestrian recognition device and a method thereof are provided to allow an environmental recognition part to recognize the peripheral environment of a vehicle on the basis of a light amount and a rainfall amount detected by sensors, thereby recognizing pedestrians depending on a poor environment such as nighttime and rainy weather. CONSTITUTION: An environmental adaptation type pedestrian recognition device includes a sensor part(110), an environment recognition part(120), and a pedestrian recognition part(130). The sensor part detects the peripheral environment of a vehicle and pedestrians. The environment recognition part recognizes the peripheral environment of the vehicle on the basis of the environmental information detected by the sensor part, and transmits pedestrian information corresponding to the environmental information recognized by the environment recognition part to the pedestrian recognition part. The pedestrian recognition part recognizes pedestrians in the peripheral environment of the vehicle on the basis of the pedestrian information transmitted from the environment recognition part. The sensor part includes an infrared sensor(111), an image sensor(112), a light amount sensor(113), and a rain sensor(114). The environment recognition part recognizes the peripheral environment of the vehicle on the basis of a light amount detected by the light amount sensor and a rainfall amount detected by the rain sensor. The environment recognition part determines the peripheral environment of the vehicle as daytime or clear when the detected light amount is greater than or equal to a predetermined threshold, or the detected rainfall amount is less than a predetermined threshold. The environment recognition part determines the peripheral environment of the vehicle as nighttime or rainy when the detected light amount is less than the predetermined threshold, or the detected rainfall amount is greater than or equal to the predetermined threshold.
