Underwater high-speed area-array camera

Abstract

The invention provides an underwater high-speed area-array camera. The underwater high-speed area-array camera comprises a camera pressure-resistant shell, and a high-speed camera, an LED lamp circuitboard and a power management module which are placed in the camera pressure-resistant shell. Pressure-resistant glass is arranged on one side of the camera pressure-resistant shell. The high-speed camera is connected with a camera. LED lamps are evenly installed on the periphery of the camera and installed on the LED lamp circuit board. The LED lamps and the camera all face the pressure-resistantglass. An FPGA chip is adopted as a processing chip of the high-speed camera. The FPGA chip is connected with a DDR chip and used for improving the processing speed and data throughput of images. TheFPGA chip is connected with an SSD hard disk and used for storing parameter configurations of the images and the high-speed area-array camera at the camera end. Underwater photographing can be continuously carried out for ten workdays, deep diving can be realized, the application range can be increased, light illumination is uniform, and the photographing speed and processing speed are high.

Description

technical field [0001] The invention relates to a shooting camera for sports competitions, in particular to an underwater high-speed area array camera. Background technique [0002] Swimming has now become a strong sport in our country. In order to meet the correct analysis of the underwater movements and posture rhythm changes of athletes at critical moments in sports competitions, especially in swimming competitions, the key screens such as take-off into the water and the end point touch board interpretation Continuous capture and analysis requires a high-speed area array camera and a supporting motion analysis system for processing and analysis. Moreover, the underwater camera can analyze the swimming strokes of the athletes, allowing the coaches to guide and correct the movements of the athletes, so that the athletes can maximize their potential. [0003] Swimming takes only a short time to enter the water and touch the touch panel, and there will be multiple people doi...

Problems solved by technology

[0004] At present, the monitoring or industrial camera systems that are widely popular in the market are composed of TI's Davinci series or Hisilicon Digital Media Video Processor as the core. The frame rate of these cameras can only reach 30 to 50 frames at high-definition resolution , the highest is 60 to 70 frames, and the ordinary cameras on the market can only dive to 30 meters, which can no longer meet the requirements of high-speed cameras at sports competitions. Underwater camera up to 100 meters
