火点监测技术在生态环保、灾害防治等领域的应用愈加广泛。为实现实时、全方位监测,提出了一种基于单目序列影像的火点实时监测方法。利用旋转相机对监测区域进行全方位巡航摄影,选取多帧影像进行位姿解算;热红外成像检测到火点后进行同位影像侦测,以排除光照和天气的影响;对目标影像进行模板匹配获取像方坐标,利用摄影测量共线方程计算火点的物方坐标,并转换为经纬度。通过实验验证了监测方法的可行性。

The applications of fire-point monitoring technology in the fields of ecological environment protection and disaster prevention and control are more and more extensive. In order to realize real-time and all-round monitoring, we proposed a real-time monitoring method based on monocular sequence image. We used a rotating camera to perform all-round cruise photography on the monitoring area, and selected multi-frame images to calculate pose. When infrared imaging detecting the fire point, we detected the image in the same position in order to eliminate the influence of illumination and weather. And then, we used template matching to obtain the target's coordinates on the image, and calculated the object coordinate of the fire point by the photographic collinear equation. Finally, we converted the object coordinate into the latitude and longitude. The experimental result proved the feasibility of this monitoring method.
