Bispectral high-speed camera based on fpga

Abstract

The invention relates to a dual-spectrum high-speed camera based on fpga. The dual-spectrum high-speed camera comprises an infrared sensor, a visible light sensor, a serial communication master-slaveinterface realized by an I2C interface, an image processing device and an image real-time display device. A register in the cmos sensor is written by using an I2C interface working time sequence, exposure of the cmos sensor is controlled, and automatic white balance opening and closing, frame rate and / or resolution are / is controlled. The infrared-based high-sensitivity cmos sensor improves the imaging speed to realize high frame rate and high speed; and a global exposure mode is adopted by using the cmos sensor, so that the moving shooting of the high-speed object is not distorted.

Description

technical field [0001] The invention relates to the technical field of high-speed cameras, in particular to an FPGA-based dual-spectrum high-speed camera. Background technique [0002] With the development of electronic technology, multispectral cameras appeared in the 1990s. This kind of multi-spectral camera with area array complementary metal oxide semiconductor (complementary metal oxide semiconductor, CMOS) or high-speed electrically coupled device (CCD) as image sensor, and large-capacity integrated circuit memory chip as storage value can image The digitalization of information avoids the cumbersome processing process of the film, and can realize the instant information displayed in real time during the test. After shooting, the image information is transmitted to the PC for data analysis, which can reduce the cycle time of the experiment and fully demonstrate the digitalization. Superiority. Most of the self-developed spectral cameras in China are CCD photosensitiv...

Problems solved by technology

However, the program does not implement a high-speed and high frame rate solution

[0005] In addition, the existing infrared cameras mainly come from traditional dsp or arm development platforms, which cannot realize high-speed real-time image processing. High-speed cameras based on fpga have also been developed recently, but they are all based on high-speed and high-resolution visible light , and there is no relevant infrared high-speed camera based on fpga
