The invention discloses a bird condition information statistical method fusing bird detection radar data and a transect method, and solves the problems that the bird population density cannot be counted and the radar data and the artificial investigation data are not fully fused when the bird detection radar data and the artificial investigation data are fused in the existing method. Fusing the enhanced data set with the bird population density, extracting the features of the data fusion set by the target recognition model based on the micro-Doppler features, and outputting a statistical result of the bird situation information in the bird flock; according to the invention, the target identification model achieves the precise evaluation of the statistical result of the bird condition information through the fusion of the bird detection radar data and the transect method, and can effectively reduce the uncertainty in the statistical process through the fusion of the enhanced data set and the bird population density with the bird population density as the prior probability. Therefore, the accuracy of bird condition information statistics is improved, and the stability and reliability of the target recognition model can be improved by using the enhanced data set.

This invention discloses a multi-parameter transect observation system and method for marine hydrology based on an unmanned vessel, relating to the field of transect observation. It addresses the problem of poor observation results in existing marine transect observation systems. The system includes a transect temperature module: performing water depth and temperature analysis on sample marine observation transects and obtaining the corresponding transect temperature index observation coefficient based on the analysis results; a transect salinity module: performing water depth and salinity analysis on sample marine observation transects and obtaining the corresponding transect salinity index observation coefficient based on the analysis results; and an observation feedback module: assessing the water body stability of the sample marine observation transect based on the transect salinity index observation coefficient and the transect temperature index observation coefficient. This invention improves the accuracy and comprehensiveness of marine transect observation results.

The invention relates to the technical field of marine ecosystem monitoring, in particular to a coral top area estimation method, which comprises the following steps of: acquiring video stream data and scale data of corals by adopting a strip-like belt method, and establishing a coral data set; establishing a detection segmentation model, and training the detection segmentation model in the coral data set; constructing a camera motion simplified model; and calculating the ratio of the actual distance to the pixel distance between the two spaced scale feature points and the translation distance of the camera, and calculating the estimated value of the coral top area. According to the coral top area estimation method provided by the invention, video stream data of the coral is acquired through a belt-like belt method, and a detection segmentation model is established, so that automatic identification and segmentation of the coral are realized, and non-destructive area estimation calculation of the coral is realized through a camera motion simplified model; the destructive measurement of measuring personnel on the coral form and the labor cost are reduced, and the change of the coral reef ecosystem can be better understood and predicted.
