  • Publication number: 20180150704
    Abstract: Provided is a method of detecting pedestrians and vehicles based on a convolutional neural network by using a stereo camera, for generating a disparity video through stereo matching in a video photographed by the stereo camera, detecting object candidates by using the disparity image, and detecting the pedestrians and the vehicles through an object detection process for the detected candidate. The method includes receiving a stereo video; acquiring a disparity video from the stereo video using stereo matching to convert the disparity video into a depth video; extracting object candidates by analyzing a histogram of the depth video; and detecting an object by using a convolutional neural network to be detected among the object candidates. Object candidates are detected using disparity video in advance, and one of the object candidates is detected whether it is a pedestrian or a vehicle, such that less time is required.

  • Patent number: 6945103
    Abstract: A tire status monitoring system monitors tire conditions, such as tire pressure, temperature, etc., thereby improving automobile safety. The tire status monitoring system provides transmitters, mounted within the vehicle tires, for transmitting tire conditions. A receiver is installed in the vehicle, for analyzing the tire condition data received from each transmitter. The transmitter includes a pressure sensor for sensing air pressure, a temperature sensor for sensing temperature in the tire; a drive detecting sensor for sensing driving velocity; a radio transmission module for modulating the input data into a radio frequency signal to transmit the modulated signal; and a control device for identifying the operation mode by the pressure, temperature and driving velocityinput from the sensors in sensing mode. The control device controls the radio transmission module so that the sensed data can be transmitted at a predetermined period according to the identified operation mode.
