Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse technology, specifically to a seedling greenhouse integrating three-dimensional moving imaging. Background Technology

[0002] As a staple crop for more than half of the world's population, the quality control of rice seedling cultivation directly affects rice yield and food security. In traditional seedling cultivation, monitoring the growth status of seedlings mainly relies on manual inspection and experience-based judgment, which has technical shortcomings such as low monitoring frequency, strong subjectivity in data collection, and delayed detection of growth abnormalities.

[0003] In large-scale seedling raising scenarios, manual observation methods struggle to achieve standardized recording and full-cycle tracking of seedling parameters, leading to frequent problems such as poor seedling uniformity and delayed detection of pests and diseases. This has become a key bottleneck restricting the improvement of intensive rice production efficiency. Although existing plant phenotypic monitoring technologies have attempted to incorporate two-dimensional image acquisition systems, they are still limited by the field of view and imaging dimension of fixed cameras, resulting in insufficient spatial resolution and weak dynamic tracking capabilities. This leads to a lack of quantitative basis for environmental control during the seedling raising period, becoming one of the key technical bottlenecks restricting the improvement of intensive rice production efficiency.

[0004] Therefore, it is necessary to propose a seedling greenhouse that integrates three-dimensional moving imaging. Summary of the Invention
