Method and device for detecting lies on basis of electrodermal response and pupil change

The invention discloses a method and a device for detecting lies on the basis of electrodermal response and pupil change. The method includes determining normal feature values of test persons according to normal electrodermal response data of the test persons in non-lying states, normal pupil data and preset weight values; determining test feature values of the test persons according to test electrodermal response data of the test persons in test states, test pupil data and the weight values; comparing the normal feature values to the test feature values to obtain lie detection results of the test persons. The method and the device have the advantages that the method and the device are high in feasibility, and high lie detection accuracy can be guaranteed. 本发明公开了种基于皮肤电反应和瞳孔变化的测谎方法及装置，该方法包括：依据测试者在未说谎状态下的正常皮肤电反应数据、正常瞳孔数据以及预设的权重值，确定所述测试者的正常特征值；依据所述测试者在测试状态下的测试皮肤电反应数据、测试瞳孔数据以及所述权重值，确定所述测试者的测试特征值；比较所述正常特征值和所述测试特征值，得到所述测试者的测谎结果。基于上述方法及装置，具有较高的可行性，可以保证测谎的准确率更高。
