Research And Implementation Of High-speed CMOS Camera

High-speed CMOS camera can capture and record the high-speed motion process of objects that cannot be distinguished by the human eye.In many occasions,high-speed transient processes need to be recorded and studied.In recent years,high-speed imaging systems have developed rapidly,but there are still problems,such as slow frame rate,narrow dynamic range,low signal-to-noise ratio,etc.,which cannot ensure that better images can be obtained in different environments.Therefore,High-speed CMOS camera as a stable and efficient tool,It is widely used in military development,industrial production and scientific research.This thesis takes the LUX1310 digital image sensor produced by LUXIMA of the United States as the research object,analyzes the performance conditions of the sensor,Aiming at the configuration requirements of sensors and the final effect to be achieved,a set of hardware and software framework was designed.The image correction algorithm and the image transmission algorithm based on Coax Press were studied to achieve the purpose of high-speed and highquality imaging.The experimental results show that the high-speed CMOS camera designed in this paper can transmit high-quality image data with an image resolution of 1280 × 1024 in real time at a transmission speed of 1000 frames per second.The proposed image transmission algorithm can make the camera frame rate up to 1000FPS;the proposed image gain algorithm increases the camera’s dynamic range to 73 d B;and the proposed image correction algorithm makes the camera’s signal-to-noise ratio up to 53 d B.Through the research on the realization method of the high-speed CMOS camera,the application field of high-speed imaging technology is expanded.
