Description

Technical Field

[0001] The present invention relates to the technical field of spectral data acquisition, and in particular to a spectral imaging data acquisition system and method. Background Art

[0002] With the continuous development of spectral imaging systems, there is an increasing need for efficient, stable, and automated spectral acquisition. For example, it is possible to automatically collect sample spectra from different perspectives and distances, efficiently establish a comprehensive spectral dataset of the sample, which is more conducive to comprehensively analyzing the spectral characterization characteristics of the sample.

[0003] In existing spectral imaging acquisition systems, most use a tripod to set up the spectral imaging device, and the lighting is also randomly adjusted and placed, and then spectral data is collected. In this way, it is impossible to stably, repeatedly, and efficiently collect the spectral data of the sample. And during the collection process, the sample needs to be manually replaced, with low efficiency and it is difficult to ensure the consistency of the sample position. Especially when collecting samples of the same batch, the position is also important. On the other hand, for the dark background and whiteboard correction of spectral imaging devices, in the actual situation, most are manually corrected and there is no automated and controllable correction. On the other hand, although there are some existing automated devices that use one-degree-of-freedom movement to collect spectral images, they have poor flexibility, and the acquisition shooting conditions cannot be digitally recorded. Information such as the angle, distance, lighting intensity, lighting angle, ambient temperature and humidity corresponding to the spectral data of the collected sample cannot be digitally recorded, and it is impossible to have both top-down and front-view shooting. And often the spectral data is affected by the lighting intensity, angle, shooting distance, angle, ambient temperature and humidity, which is crucial for stably analyzing the spectral properties of the sample.

[0004] Therefore, there is an urgent need for a spectral imaging data acquisition system and method that can automatically collect spectral data of samples and improve the acquisition accuracy and efficiency. Summary of the Invention

The controller 600 drives the spectral imaging device 120 to perform three-dimensional movement according to the first information, and drives the spectral imaging device 120 to rotate according to the first information. The controller 600 controls the spectral imaging device 120 to collect spectral data of the sample. Thus, the spectral imaging device 120 can be controlled to perform three-dimensional movement and driven to rotate according to the first information, so that the position and angle of the spectral imaging device 120 can be automatically adjusted to improve the degree of automation in the spectral data acquisition process, reduce the errors generated during manual adjustment of the spectral imaging device 120, and improve the acquisition accuracy and acquisition efficiency.

[0081] Further, before collecting spectral data, the controller 600 controls the dark bottom baffle 180 to block the spectral imaging device 120, and the controller 600 controls the spectral imaging device 120 to perform dark bottom correction. The controller 600 obtains second information, which is the position and angle information of the first fill light 140 and the second fill light 160. The controller 600 drives the first fill light 140 and the second fill light 160 to move and rotate according to the second information, and the first fill light 140 and the second fill light 160 illuminate the sample. The controller 600 controls the white board 210 to be vertically positioned on the side of the sample facing away from the spectral imaging device 120, and controls the spectral imaging device 120 to perform white board 210 correction. Thus, automatic control of the first fill light 140 and the second fill light 160 can be achieved, so as to improve the degree of automation in the spectral data collection process, reduce the errors generated when manually adjusting the spectral imaging device 120, and improve the collection accuracy and collection efficiency. Automatic dark bottom correction and white board 210 correction of the spectral imaging device 120 can also be performed, thereby improving the degree of automation in the spectral data collection process, reducing the errors generated when manually adjusting the spectral imaging device 120, and improving the collection accuracy and collection efficiency.
