Problems solved by technology

It will increase the extra time for taking pictures and affect the efficiency of image collection
[0006] 2. There is a problem of loss of single / multiple spectral images
If there are too many skipped images, it will add extra time and reduce the efficiency of taking photos
If there are fewer skipped images, the spectral image will be incorrect, which will affect the subsequent spectral curve analysis

Abstract

The invention provides a method and device for rapidly obtaining tunable spectral images and a storage medium, and the method comprises the following steps: 1, receiving a spectral band list instruction issued by an upper computer, the spectral band list instruction being spectral images of which spectral bands need to be obtained; step 2, automatically issuing a spectrum switching instruction to the tuner, and controlling the CMOS Sensor to perform exposure imaging after spectrum switching succeeds; step 3, receiving image data sent by the CMOS Sensor after imaging; step 4, sending the image data to an upper computer; and 5, starting to collect the spectral image of the next spectral band, and repeating the steps 2 to 4. In the control process, the photographing time can be shortened, and the photographing efficiency can be improved. And the number of times of control instruction interaction between the upper computer and the lower computer is reduced. The upper computer only needs to continuously and quickly acquire the spectral images sent by the lower computer after issuing the wave band list, so that the problem that the spectral images are lost due to the fact that the images are not acquired in time is avoided.

Description

technical field [0001] The invention belongs to the technical field of tunable spectral cameras, and in particular relates to a method, device and storage medium for rapidly acquiring a tunable spectral image. Background technique [0002] Tunable spectroscopic camera imaging technology can be divided into scanning methods based on multiple exposures and computational imaging methods based on single exposure from the time dimension. The characteristic of the multiple exposure imaging technology is that if the spectral image of multiple spectral bands is to be obtained, the spectral camera needs to perform operations such as switching spectral bands and exposure imaging multiple times. Based on this feature, when shooting multiple spectral images, it is necessary to complete the rapid switching of multiple spectral bands, acquire images, and transmit images in a very short period of time. The entire photographing process is as follows: figure 1 shown in the flowchart. [00...
