    • A communication system comprises a NAT device, a terminal device, and a communication control device. The communication control device comprises a first storage unit that stores a NAT address, a first receiving unit that receives a type request signal, a first determination unit that determines whether the NAT address matching a source IP address of the type request signal is stored in the first storage unit, and a first transmitting unit that transmits the type information associated with the NAT address matching the source IP address to the terminal device. The terminal device comprises a second transmitting unit that transmits the type request signal, a second receiving unit that receives the type information, and a communication control unit that performs Peer to Peer communication with another terminal device that is subordinate to another NAT device by performing communication using a method to establish communication based on the received type information.

    • A technique is provided that can precisely measure the photographing position and posture of a photographing device and the coordinates of an object from moving images or photographed images that sequentially change gradually, even in the case with the need to process the sway of the photographing device and the disappearance and reappearance of characteristic points. An image processing device 100 according to the present invention includes: a photographed image acquisition 2 section for sequentially acquiring photographed images, that change gradually, of a relatively moving object; a characteristic extraction section 3 for extracting characteristic points from a photographed image acquired with the photographed image acquisition section; a characteristic point tracking section 4 for searching a plurality of the photographed images acquired before or after the photographed image from which the characteristic points have been extracted, for candidate corresponding points corresponding to the characteristic points, to keep track of the characteristic points; and a processing section 5 for determining corresponding points from the candidate corresponding points based on tracking results to calculate coordinates of a photographing position or the object using the determined corresponding points.
    • 提供一种技术,即使在需要处理拍摄装置的摆动的情况下,也可以精确地测量拍摄装置的拍摄位置和姿势以及从逐渐变化的运动图像或拍摄图像的对象的坐标,以及 特征点的消失和再现。 根据本发明的图像处理装置100包括:拍摄图像获取2部分,用于顺序地获取相对移动的对象逐渐变化的拍摄图像; 特征提取部3,用于从由拍摄图像获取部获取的拍摄图像中提取特征点; 特征点追踪部分4,用于搜索在提取了特征点的拍摄图像之前或之后获取的多个拍摄图像,用于跟踪特征点的候选对应点,以跟踪特征点; 以及处理部分5,用于基于跟踪结果确定来自候选对应点的对应点,以使用所确定的相应点来计算拍摄位置​​或对象的坐标。
