<p><P>PROBLEM TO BE SOLVED: To provide an obstacle detecting device for appropriately detecting a reflected wave from an object for essentially providing a reflected wave, such as an obstacle and a parking frame. <P>SOLUTION: This obstacle detecting device is equipped with: a transmitting means for transmitting a transmitted wave to a periphery of a vehicle, a receiving means for receiving, as a received reflected wave, the reflected wave from the object of the transmitted wave; a road surface reflected wave detecting means that determines whether the received reflected wave received by the receiving means continuously occurs for a certain time, and detects the received reflected wave as a reflected wave from the road surface when the received reflected wave continuously occurs for the certain time; a setting means for setting a noise determination threshold for detecting the reflected wave from the road surface included in the received reflected wave received by the receiving means, based on the received reflected wave determined to be the reflected wave from the road surface; and an object reflected wave detecting means for detecting the reflected wave of the object other than the road surface from the received reflected wave received by the receiving means using the noise determination threshold. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
