摘要： A method for inspecting a marine vessel underdeck utilizes a video camera such as a digital video camera with a magnifying or telephoto lens. The method produces a magnified image on a monitor for viewing by an inspector that appears to be no more than about 24 inches (61 cm) away. The method includes the step of filming the uuderdeck of a distance of about 40-70 feet (12-21 m). The lens provides a focal length of between about 15 feet (4.6 m) and 150 feet (46 m). Thus the method is conducted at a workable focal range of between about 15 feet (4.6 m) and 150 feet (46 m). The lens preferably has a focal length of between 30 feet (9 m) and 75 feet (23 m). The method includes the step of scanning the suspect area of the underdeck of a speed of about 1 inch (2.54 cm) per second to three feet (91.4 cm) per second. The preferred method contemplates scanning of the suspect area of a rate of between about 0.5-1 foot (15.2-30.5 cm) per second. The digital video can be focused on a particular area for about 15-30 seconds to create a loop for vetting.
摘要翻译： 用于检查海洋船只底座的方法利用诸如具有放大镜或长焦镜头的数字摄像机的摄像机。 该方法在监视器上产生放大的图像，以由检查员观看，其看起来不超过约24英寸（61厘米）。 该方法包括拍摄约40-70英尺（12-21米）距离的陀螺仪的步骤。 透镜提供约15英尺（4.6米）和150英尺（46米）之间的焦距。 因此，该方法在约15英尺（4.6米）和150英尺（46米）之间的可操作的焦距范围内进行。 透镜优选地具有在30英尺（9米）和75英尺（23米）之间的焦距。 该方法包括以每秒约1英寸（2.54cm）/秒的速度扫描底板的可疑区域到每秒三英尺（91.4cm）的步骤。 优选的方法考虑以每秒约0.5-1英尺（15.2-30.5cm）之间的速率扫描可疑区域。 数字视频可以在特定区域聚焦约15-30秒，以创建一个循环来进行审查。
