Patent number: 9928599Abstract: Provided are an apparatus and a method for detecting an object in an image, and particularly, an apparatus and a method for detecting a vehicle in an image. The present invention has been made in an effort to provide an apparatus and a method for object detection based on dominant pixel information which generate an average image and a standard deviation image of training object images, acquire a feature area representing a feature of a training object, and detect an object by using a value acquired by calculating a similarity between the average image in the feature area and a target image as a feature vector to efficiently detect a target object with a small calculation amount.Type: GrantFiled: November 25, 2015Date of Patent: March 27, 2018Assignee: INDUSTRY—ACADEMIC COOPERATION FOUNDATION, YONSEI UNIVERSITYInventors: Euntai Kim, Jisu Kim, Jeonghyun Baek

Patent number: 9810787Abstract: An apparatus and method for recognizing an obstacle using a laser scanner are provided. The apparatus includes a laser scanner that is installed at the front of a traveling vehicle and is configured to acquire laser scanner data configured of multiple layers in real time and an imaging device installed at the front of the moving object and is configured to acquire video data. A controller is configured to divide first laser scanner data item and second laser scanner data item acquired by the laser scanner into multiple layers to extract measurement data items each existing in the respective layers and is configured to compare the measurement data items in the same layer of the multiple layers to determine whether an obstacle is present ahead of the traveling vehicle. Additionally, the controller is configured to combine the laser scanner data reflecting whether an obstacle is present with the video data.Type: GrantFiled: December 27, 2013Date of Patent: November 7, 2017Assignees: Hyundai Motor Company, Kia Motors Corporation, Industry-Academic Cooperation Foundation, Yonsei UniversityInventors: Minkyun Yoo, Hyunju Kim, Hoon Lee, Youngwon Kim, Hyungsun Jang, Baehoon Choi, Beomseong Kim, Euntai Kim
