摘要
水下激光照明成像是水下目标探测的重要手段,在海洋探测中具有重要的应用价值。根据水下激光照明成像设备主要技术指标及关键特性参数的测量需求,研究了水下激光照明成像设备检测方法。采用监视比测量法实现了水体激光衰减系数的测量,建立了实验室条件下的模拟水下检测环境,通过采集被测照明成像设备在不同水下环境条件下对不同对比度和不同分辨率靶标所成的图像,对其进行分析和识别,测量其最大衰减长度,评价其成像质量。
The underwater laser lighting and imaging is an important method for the detection under the water, especially for ocean detection. The testing method of underwater laser lighting and imaging equipment has been researched according to its main characteristics. The water attenuation coefficient has been measured by the surveillance ratio method. A simulant underwater testing condition has been founded in the laboratory. The images of the targets with different contrast and spacing frequency by the underwater laser lighting and imaging equipment in different conditions have been researched, and the maximal attenuation length has been measured and the imaging quality has been evaluated based on acquisition, analysis and identification of the image.
