The invention relates to the technical field of space remote sensing equipment, and provides a satellite-borne large-view-field visible light camera calibration device. The calibration plate is mounted at the front end of the camera lens hood; the calibration plate control mechanism is installed on one side of the camera lens hood and connected with the calibration plate to drive the calibration plate to be opened or closed relative to the camera lens hood. When the calibration plate is closed, the calibration plate can cover a front-end light path of the camera lens hood, a light source of the calibration plate serves as a uniform radiation source to carry out relative radiation calibration on the camera, and when the calibration plate is opened, the front-end light path of the camera lens hood is not shielded, so that the camera can normally image a space target. For a space dark and weak target observation camera, a calibration system which is installed at the front end of a camera light shield and can be opened and closed is designed, a calibration cover is provided with a brightness-adjustable uniform area light source based on LED active light emitting and diffuse transmission glass, a full-light-path-level relative radiometric calibration device is achieved, and especially relative radiometric calibration under low light and weak light can be achieved.

The invention discloses a gastrodia elata quality nondestructive testing system based on a hyperspectral imaging technology, and relates to the technical field of gastrodia elata processing equipment.The gastrodia elata quality nondestructive testing system is characterized in that the system is connected in series according to S1-S6: PRI, BWI and time constants are collected and extracted according to temperature and humidity perturbation and time sequence; thermal / mass diffusion generates a depth weight D (x, y) to inhibit surface dominance; multi-angle reflection and diffuse transmission imaging are carried out to obtain multiple geometric spectrums; carrying out physical micro body rendering inversion in combination with non-negative unmixing, and outputting voxel distribution and virtual slices of water, polysaccharide, gastrodin, p-hydroxybenzyl alcohol, parishin, starch and the like; if not, triggering photoacoustic calibration to obtain density and a cavity mask; the consistency of fusion dynamic, imaging and acoustics is updated through the posteriori of the serial product formula; and generating a TFC fingerprint code through posterior distillation and optimizing few bands, thereby realizing second-level online grading and low-cost deployment. According to the system, dynamic, structural and chemical three-dimensional information is synchronously obtained without damaging a sample, the accuracy, depth resolution and robustness are improved, and the system is suitable for production line quality control and traceability.
