Target tracking method of ship wireless sensor network based on retinex algorithm

为保证不同海上环境下,舰船无线传感网络目标跟踪的可靠性,提出基于Retinex算法的舰船无线传感网络目标跟踪方法。采集舰船目标图像,采用改进的Retinex算法增强舰船目标图像,提升图像细节和质量,通过无线通信方式进行图像传输,依据摄像头标定原理转换目标图像坐标为世界坐标系坐标,获取舰船目标的实际位置,完成舰船无线传感网络目标跟踪。测试结果显示:该方法增强后图像的边缘清晰度提升,跟踪性能良好,帧率的最高结果达到127 fps左右;舰船目标发生遮挡和尺度发生变化2种情况下,仍然能够可靠完成目标跟踪。

In order to ensure the reliability of ship wireless sensor network target tracking in different marine environments,a ship wireless sensor network target tracking method based on Retinex algorithm is proposed.Collect the ship target image,use the improved Retinex algorithm to enhance the collected ship target image,improve the image details and quality,transmit the image through wireless communication,convert the target image coordinates to the world coordinate system coordinates according to the camera calibration principle,obtain the actual position of the ship target,and complete the ship wireless sensor network target tracking.The test results show that the edge definition of the enhanced image is improved,the tracking performance is good,and the highest frame rate is about 127 fps;When the ship target is blocked and the scale changes,the target tracking can be completed reliably.
