The present application relates to the technical field of
database construction, and particularly relates to a construction method of a foraminifera morphological feature
database, comprising the following steps: S1, collecting foraminifera images from multiple sources, identifying scale drift and shooting deviation based on principal axis normalization and local vorticity field, performing structure-preserving
image enhancement, and outputting an enhanced image set consistent in shell substance, shell arrangement, shell opening,
suture line and micro-pore features; S2, extracting a multi-scale shell structure atlas, constructing a structure-semantic coupled
label nested tree, performing
polysemy recognition and
ambiguity resolution, and generating a structured
annotation set; S3, fusing the image set and the
annotation set, and constructing a three-layer
database model containing a part layer, an attribute layer and a variation layer according to the
label nested tree. Through
image structure enhancement, semantic
ambiguity resolution and three-layer
database construction, the present application effectively improves the recognition accuracy of foraminifera morphological features, the
label organization logicality and the
information retrieval efficiency.
