The invention discloses a terminal device, a foreign matter detection result evaluation method thereof, a computer storage medium. The foreign matter detection result evaluation method comprises the following steps: acquiring at least one to-be-identified detection image and a corresponding actual foreign matter parameter, wherein the detection image comprises at least one detection image acquiredby a millimeter wave / terahertz security check instrument; identifying a foreign matter of the to-be-identified detection image, and acquiring an identified foreign matter parameter; based on an actual foreign matter parameter and the identified foreign matter parameter, obtaining a comparison result of the to-be-identified detection image through calculation, wherein the comparison result comprises detection rate and false alarm rate; and evaluating accuracy of a detection result based on the comparison result and a preset strategy. By the foreign matter detection result evaluation method above, the terminal device provided by the invention can comprehensively evaluate performance of different models, comparison between the models is facilitated and the model with relatively higher comprehensive capability can be selected.
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 ...
