为了实现水下微光高速摄像系统最佳的成像效果,本文首先深入分析了水下30-40米左右微光条件下高灵敏度高速摄像机的物方和像方的光照度需求,进而设计出合适的辅助照明方案,然后通过实验分析了照射方向与摄像机拍摄方向的角度以及照明灯的发光强度对成像质量的影响.上述分析和实验结果达到了全系统在6米左右清晰成像的基本要求.
為瞭實現水下微光高速攝像繫統最佳的成像效果,本文首先深入分析瞭水下30-40米左右微光條件下高靈敏度高速攝像機的物方和像方的光照度需求,進而設計齣閤適的輔助照明方案,然後通過實驗分析瞭照射方嚮與攝像機拍攝方嚮的角度以及照明燈的髮光彊度對成像質量的影響.上述分析和實驗結果達到瞭全繫統在6米左右清晰成像的基本要求.

For the best imaging quality of underwater high-speed photograph system, by the thorough analysis of illuminance require-meat in both object space and image space for high sensitive high-speed camera in the circumstance of low light level between 30 and 40 meters in the water, a plan applied to assistant illumination system for underwater high-speed photograph is designed. The trial results meet the basic requirement that the system has a transparent image with the imaging distant of 6 meters.
