摘要
大空间火源的空间位置的定位是火灾自动探测和自动扑救中间的重要环节。在分析火灾图像和以往图像型火灾空间的相关定位技术基础上,根据计算机视觉原理,利用固定在自动消防水炮末端的单一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,利用极线几何扫描式单摄像机空间定位原理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 analysis of fire images and fire-ever images location technologies, computer vision theory via one digital Charge Coupled Device camera fixed at the end of the hydrant chamber. While the hydrant is pivoting, continuous images are taken from the Charge Coupled Device 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 Charge Coupled Device camera in fire location process are the essential parameters to calculate the space coordinates of fire.
