The method not only ensures safe production of grains, but also realizes a mode of'simultaneous production and restoration 'for extracting cadmium from soil through straw removal, and solves the problem of how to effectively deal with atmospheric sedimentation cadmium pollution and simultaneously extract and restore cadmium from soil while reducing the cadmium content of rice.

This invention discloses a cascaded detection method for dynamic allocation of computing power in video surveillance based on prior knowledge, specifically including the following steps: S1, data acquisition and generation of domain of interest; S2, dynamic allocation of computing power; S3, cascaded detection; S4, alarm evidence collection and feedback. This invention relates to the field of intelligent video analysis and resource scheduling technology. This cascaded detection method for dynamic allocation of computing power in video surveillance based on prior knowledge generates domains of interest based on task text and divides camera channels into active / dormant states accordingly. This reduces the inference frequency in non-interested periods and areas, thereby reducing ineffective computing power usage. Through two-level cascaded inference of "full-image human body localization + fine recognition within the ROI," it can reduce interference from complex backgrounds in wide-angle scenes and improve the accuracy of identifying the violation attributes of small targets. Through the export of evidence fragments from a circular cache and the return of manual confirmation, alarm evidence retention can be achieved.
