Embodiment 1

[0045]Theoretically, if the exposure time is increased and the moving target is always illuminated by artificial light sources, there will be shadows formed by the moving target on an image, and such a picture cannot clearly distinguish the moving target, so there is no practical application value. However, if the artificial light source used is irradiated according to a certain frequency and a certain time, then the moving target will appear on an image with as many clear images as the number of times the artificial light source irradiates the moving target during the exposure time. The images of objects at different times in the image are separated and the separated images are sharpened, so that a picture can be decomposed into several pictures to form a sequence of moving targets and increase the number of frames exponentially. According to this method, the same effect as that of a traditional camera can be achieved on the basis of reducing costs. If a light source of one ...

Abstract

The invention discloses a method for separating a dynamic image from mixed light. According to the method, an RGB (Red, Blue, Green) three-color light source is adopted for sequentially irradiating a moving target in primary exposure time, and a moving image is obtained; the moving image is separated to obtain corresponding red main body images, blue main body images and green main body images; and the separation step comprises the processes that: the moving image is converted from an RGB color space to an HSV (Hue, Saturation, Value) color space, and an H component is used for separating out a red region and a green region; the RGB color space is converted into a CIE L*a*b* color space, and a b* component is used for obtaining a blue region; and a plurality of images shot at the same time intervals are respectively subjected to image segmentation, and corresponding red, green and blue main body pictures of the images are connected into the dynamic image. Therefore, the frame number can be exponentially increased, and finally, the dynamic image is formed. The defect of high requirement on hardware is overcome in a software mode. The method provided by the invention has the advantages that the operation is simple; the practicability is high; and the precision is high.

Description

technical field [0001] The invention relates to the field of image processing and high-speed camera research, in particular to a method for separating dynamic images in mixed light to form dynamic images. Background technique [0002] High-speed photography is to closely link time information and space in the process of high-speed motion changes for image recording, and then continuously record high-speed and transient processes, and finally use image analysis equipment for quantitative calculations. It was used in ballistic analysis in the early days. At present, it has gradually expanded from military to civilian, from industry to medical and biological fields, and from macroscopic mechanical motion to microscopic mechanism research. A high-speed camera can sample a high-speed moving target multiple times in a short period of time. When these samples are displayed at a normal speed, the change process of the moving target recorded by the sample can be clearly and slowly pr...
