The application provides a kind of based on visual detection's sports glasses dimming film evaluation method and system, it is related to sports glasses manufacturing technical field, its technical solution main point is: by obtaining positioning map, determine clamping offset and correct, convert image to uniform lens coordinate, compare the candidate abnormal area in different images and determine its stability, finally mark effective feature and determine evaluation result, effectively solve the problem that visual information is unstable in prior art due to clamping deviation and observation condition change, ensure the objectivity and accuracy of evaluation result, have by clamping offset correction and image coordinate uniform, effectively eliminate the visual information fluctuation caused by clamping deviation and observation angle change, ensure that visual information accurately reflects the real state of film, thereby improve the objectivity and accuracy of evaluation result.

This application provides a standard working time dynamic self-tuning method based on the PID algorithm, applied in the field of production management technology. It obtains a dataset of measured time consumption for a target task over multiple execution cycles, preprocesses the dataset to remove outliers, and obtains an effective working time feature set. The logical deviation between this effective working time feature set and the current target reference value is determined, and a PID control algorithm is executed based on this deviation to achieve precise control of the working time data. During the iterative update of the target reference value, an ELM prediction model is used to dynamically adjust the control parameters of the PID control algorithm based on historical deviation trends. Finally, when the fluctuation range of the target reference value and the prediction error meet a preset threshold, the final standard working time is output, ensuring the stability and accuracy of the standard working time. This method has the advantage of dynamically adapting to changes in the production environment and improving the accuracy and stability of the standard working time.
