The present application discloses a terminal device and a method for evaluating foreign object detection results and a computer storage medium thereof. The method for evaluating foreign object detection results includes: acquiring at least one detection image to be identified and corresponding actual foreign object parameters, wherein the detection image includes millimeter wave / At least one detection image collected by the terahertz security inspection device; identify the foreign matter in the detection image to be recognized, and obtain the foreign matter recognition parameter; based on the actual foreign matter parameter and the foreign body recognition parameter, calculate and obtain the comparison result of the detection image to be recognized, and compare the result Including the detection rate and false alarm rate; based on the comparison results and preset strategies to evaluate the accuracy of the detection results. Through the above method for evaluating foreign matter detection results, the terminal device of the present application can comprehensively evaluate the performance of different models, facilitate comparison between models and select a model with higher comprehensive ability.
Description
technical field [0001] The present application relates to the technical field of security inspection applications, in particular to a terminal device, a method for evaluating foreign object detection results, and a computer storage medium. Background technique [0002] In the field of security inspection, the foreign object detection model uses different performance indicators to evaluate the model and often has different results, which means that the quality of the model is relative. The quality of the foreign object detection model depends not only on the algorithm and data, but also on the requirements of the task. Therefore, it is very necessary to select a reasonable model evaluation index in the detection process of security detectors. [0003] In scientific research or competitions, the recall rate and precision rate of the foreign object detection model are commonly used measurement indicators, but these evaluation indicators do not take into account the proportion ...
