The invention relates to the technical field of environmental monitoring and water ecological safety, in particular to a eukaryotic algae outbreak early warning method and system based on genus-level specific recognition. The method comprises the following steps: collecting a water body sample at a monitoring position according to a preset sampling plan, collecting an environment measurement value, and respectively obtaining environment parameter data, a water sample sampling identifier and a sampling timestamp; extracting nucleic acid from the water sample at the monitoring position based on the water sample sampling identifier, performing targeted amplification, and performing high-throughput sequencing at the same time to obtain eDNA original sequencing data; therefore, by constructing the eukaryotic algae outbreak early warning process based on genus-level specific recognition, the problems that in a traditional method, sampling disturbance is uncontrollable, sequence judgment precision is insufficient, trend recognition is lagged, and an early warning link is not transparent are solved, and the accuracy, stability and traceability of early judgment of algae outbreak are improved.

The invention provides a self-adaptive target grabbing sequence determination method, and relates to the technical field of data processing. The method comprises the following steps: segmenting current three-dimensional point cloud data of a target unloading area to generate pose information of a to-be-grabbed object; performing multi-dimensional quantitative evaluation on each to-be-grabbed object based on the pose information to generate a feature score; fusing the feature score with the pose information of the to-be-grabbed object, and constructing a comprehensive state vector at the current moment; inputting the comprehensive state vector into a pre-trained reinforcement learning strategy network to obtain an accumulated return value of each to-be-grabbed object, and selecting the to-be-grabbed object with the maximum accumulated return value as a current grabbed object to be grabbed; and the steps are repeated until the object to be grabbed does not exist in the target unloading area, multi-dimensional physical and geometric characteristics can be comprehensively considered, and therefore the overall efficiency and safety of unloading operation are improved.
