Abstract

The invention discloses a method for prolonging the shooting time of a high-speed camera, comprising the following steps: firstly, compressing a high-resolution image collected by a CCD or a CMOS at the high-speed camera end, and storing the obtained compressed image data in a memory of the high-speed camera; Secondly, the compressed image data in the high-speed camera memory is imported into the computer through the high-speed camera data interface or network, and the desired image is restored on the computer side through the compressed image reconstruction algorithm. The algorithm of the method of the present invention is simple and easy to realize by hardware. Only the pixel discarding operation needs to be performed on the high-speed camera side, and the shooting duration of the high-speed camera can be extended in the existing high-speed camera through minor hardware or software changes.

Description

technical field [0001] The invention relates to a high-speed imaging technology, in particular to a method for extending the shooting time of a high-speed camera. Background technique [0002] In the research fields of aerodynamics, fluid mechanics, explosive mechanics and many other disciplines, it is usually necessary to use high-speed cameras to observe rapidly changing physical or chemical phenomena. In practical applications, due to the limitation of the bandwidth of the camera data transmission interface, the massive image data captured by the high-speed camera can only be stored in the camera memory. Due to the high cost of memory, the memory capacity of the camera is usually small, and it is difficult to achieve large-capacity image data storage, resulting in the inability to shoot high-resolution videos for a long time. [0003] In the existing high-speed imaging technology, in order to realize long-term shooting, the image resolution must be reduced. Such as fig...
