摘　　要：灭火弹空中投放是无人机输电线路巡检火灾处理过程中必不可少的环节,投放定位精度直接关系到灭火效果,但现行方法在实际中应用效果并不理想,定位偏差比较大,灭火弹有效投放率比较低,为此提出基于图像识别的无人机输电线路灭火弹空中投放定位方法。通过无人机搭载CDD相机获取输电线路图像信息,并采用加权平均法对输电线路图像灰度化,利用图像识别技术识别定位图像中火灾,并通过坐标转换定位无人机输电线路灭火弹空中投放位置,实现基于图像识别的无人机输电线路灭火弹空中投放定位。经实验证明,设计方法应用下灭火弹空中投放定位偏差得到了有效的降低,灭火弹有效投放率得到了有效的提高。Aerial delivery of fire extinguishing bombs is an essential link in the fire treatment process of UAV transmission line inspection,and the positioning accuracy of delivery is directly related to the fire extinguishing effect.However,the application effect of the current method in practice is not ideal,the positioning deviation is relatively large,and the effective delivery rate of fire extinguishing bombs is relatively low.Therefore,an aerial delivery location method of fire extinguishing bombs for UAV transmission lines based on image recognition is proposed.The image information of the transmission line was obtained by the CDD camera mounted on the UAV,and the weighted average method was used to grayscale the image of the transmission line,and the fire in the location image was identified by image recognition technology,and the aerial delivery location of the fire-extinguishing bomb in the transmission line of the UAV was located by coordinate conversion,so as to realize the aerial delivery location of the fire-extinguishing bomb in the transmission line of the UAV based on image recognition.The experimental results show that the positioning deviation of fire-fighting projectile in the air can be effectively reduced and the effective delivery rate of fire-fighting projectile can be effectively improved.
