A high-speed camera module shooting method based on field of view decomposition

Abstract

The invention discloses a high-speed camera module shooting method based on field of view decomposition, and relates to the technical field of photography. The camera module acquires time-series single-frame images through a lens array, and arranges them on a CMOS to form X sub-frame images, wherein , the number of lenses in the lens array is the same as the number of sub-frames, the same cylindrical lens is used for the lens, and the number of frames of the camera module is Y; the arranged sub-frame images are read out sequentially by CMOS to obtain each image after imaging Frame images, and perform correction calculations on each frame of images to restore them to a sub-frame image sequence in the direction of the optical axis; image fusion is performed on the horizontal pixels of the sub-frame image sequence to obtain an image sequence with enhanced light intensity.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a high-speed camera module shooting method based on field of view decomposition. Background technique [0002] As an important means of modern optical measurement, high-speed photography can provide a large amount of detailed information on the movement and shape changes of high-dynamic targets. Analyzing the recorded images can obtain the quantitative movement parameters of the target, which can be widely used in the field of high-precision movement measurement. Compared with conventional camera measurement equipment, high-speed camera measurement equipment can provide measurement data with wider dynamic range, higher accuracy, more comprehensive parameters and richer content. For now, high-speed cameras not only consume a lot of power, but also commonly used batteries cannot support them due to the power consumption of high-speed cameras; in addition, the sensor of a high-s...

Problems solved by technology

For now, high-speed cameras not only consume a lot of power, but also commonly used batteries cannot support them due to the power consumption of high-speed cameras; in addition, the sensor of a high-speed camera is too large compared to the sensor of a mobile phone. If the camera of a mobile phone is used as a high-speed camera, Due to the size of the mobile phone space, it cannot be made into a large-area photosensitive device. If the frame rate of the mobile phone camera is forcibly increased, the image will be dark. If a special photoreceptor is used, the cost will be too high
