Columnar core outer surface hyperspectral image reconstruction method

The invention belongs to the technical field of rock core scanning and earth science, and particularly relates to a columnar rock core outer surface hyperspectral image reconstruction method, which comprises the following steps of: 1, acquiring a columnar rock core multi-angle hyperspectral image; 2, cutting an effective area of the multi-angle hyperspectral image of the columnar core; step 3, carrying out radiation correction on the multi-angle hyperspectral image of the columnar rock core; step 4, geometric correction of the multi-angle hyperspectral image of the columnar rock core; 5, splicing the multi-angle hyperspectral images of the columnar rock core; and step 6, removing an overlapping region of the spliced image to obtain a cylindrical core outer surface hyperspectral image reconstruction result. According to the method, radiation brightness distortion and geometric shape distortion generated in the hyperspectral image scanning process can be effectively corrected, and therefore accurate reconstruction of the hyperspectral image on the outer surface of the whole columnar rock core is achieved.

A method and system for monitoring pyrenoid algae based on binocular images

The present invention relates to a method and system for monitoring pyrenoid algae based on binocular images, and specifically to the field of biological monitoring. The method collects binocular image data with pyrenoid algae as monitoring targets in real time, establishes an adaptive background model to achieve dynamic adaptive following of monitoring targets, generates a disparity map and generates a depth map based on focal length and baseline distance, constructs three-dimensional information of the pyrenoid algae, extracts relevant features of the pyrenoid algae, constructs a deep learning model to perform probability distribution of the health status of the pyrenoid algae, constructs support vector regression to predict the growth rate of the pyrenoid algae, improves the judgment accuracy of the health status of the algae, uses a generative adversarial network to perform AI model training to generate the best pyrenoid algae image, uses Euclidean distance to calculate the similarity between the best pyrenoid algae image and binocular image data, and more clearly understands the matching degree between the generated image and the actual image.
