基于CCD图像的火灾空间定位方法

Automatic fire location by CCD images in big space

大空间中火源的空间位置的定位,一直是火灾自动探测与自动扑救中的难点。研究了一种利用单一CCD摄像头进行火灾自动空间定位的方法。根据计算机视觉原理,利用固定在自动消防水炮末端的CCD摄像头随水炮旋转扫描时的角度、位移变化,将CCD摄像头在不同位置所拍摄的图像中火源图像坐标和火源的空间坐标建立联系,从而实现了火源空间位置的自动定位。

An automatic fire location method in big space was developed. This fire location method is realized based on computer vision theory via one digital CCD camera fixed at the end of the hydrant chamber. While the hydrant is pivoting, continuous images are taken from the CCD camera and transmitted into computer. Once a fire is detected from the images, it can be automatically located using these images by certain arithmetic. Displacement and pivot angle of the CCD camera in fire location process are the essential parameters to calculate the space coordinates of fire.
