Underwater Imaging System

概述

Underwater imaging applications such as the camera systems on submersible Remotely Operated Vehicles (ROVs) rely on live video streams to be able to control, navigate and collect imaging data from the ROV successfully. Traditionally this functionality is provided via an LCD screen on the controllers for such submersibles, which often include a variety of mechanical buttons to control different functions on the ROV. Increasingly designers are looking to simplify the control interfaces for submersible ROVs whilst maintaining the video streaming functionality.

These mechanical buttons and video LCD panel for navigation and imaging can be replaced with a touch screen to enhance the user experience and simplify the systems operation. The Embedded Video Engine (EVE) provides designers with the ideal solution to incorporate a touch interface and video streaming requirements for submersible ROV controllers.

嵌入式视频引擎 (EVE) IC 可与低成本 MCU 和摄像头一起使用，以：

• Create high quality video images allowing the user to view imaging data.
• Display custom gauges and numerical readouts.
• Design the interface from the ground up with full flexibility
• 在显示屏上显示叠加文本，无需额外的 LED 等即可提供清晰的状态信息。
• 驱动各种形状和尺寸的屏幕，例如 1280×800 分辨率和 12.3 英寸宽幅屏幕
• 轻松将触摸控制集成到界面中

​主要特征​

The following key features of EVE make it ideal for an underwater imaging application:​

• 使用彩色图形从摄像机创建高质量的实时视频源
• Overlay text and controls on the video image
• Use widgets such as gauges and graphics primitives such as lines for readouts
• Use touch tagging to simplify user controls such as buttons
• Custom fonts allow multi-language support for text and on the touch screen icons.
• Audio output and built-in sounds allow touch feedback and alert sounds to be easily added.
