The application discloses a multi-modal depth perception and grasping system based on transparent objects, and relates to the field of robot operation, comprising a multi-spectral perception module, a depth correction module, a grasping posture generation module and a control module. The application comprehensively acquires visual information and thermal radiation information of the transparent object by combining two perception methods of RGB-D image and thermal imaging (TIR) image, and analyzes systematic errors of the depth map to detect error sources of the RGB-D camera and the TIR camera. The system adopts an encoder-decoder model as a depth correction core, the model extracts complementary features of the RGB-D image and the TIR image through a modal exclusive encoder, and utilizes a feature fusion module to complete feature alignment and integration, thereby effectively improving the depth estimation accuracy on the transparent surface. Meanwhile, a Bayesian optimization method is adopted to optimize hyperparameters of the depth correction model, through hyperparameter optimization and model fitting processing, the system effectively avoids overfitting and underfitting problems, and further improves the robustness of the depth correction model and the grasping accuracy of the transparent object.

The invention discloses a multi-source data fusion metering method and system for skid-mounted three-phase separation equipment, and particularly relates to the technical field of data analysis, and the method is realized through the following steps: 1, based on a preset data source type, employing a corresponding sensor to collect equipment operation data, and forming a collection data set; 2, dividing each data source data set into sub-data sets according to a fixed time length; 3, performing feature extraction on the sub-data sets, analyzing quality change and fluctuation conditions, and generating feature data; 4, importing the feature data into a convolutional neural network model for classification, and judging whether the sub-data set is high-quality data or not; step 5, according to a classification result, determining whether to send out an early warning signal to guarantee the accuracy of data fusion; according to the method, division and feature extraction are carried out on the multiple data sources collected by the equipment, high-quality and low-quality data can be effectively recognized and classified, credible data sources can be screened out, and the accuracy of multi-source data fusion is improved.
