    摘要:

    神经心理测试可以对各认知域受损严重程度做出客观评价,是检测疾病进展、评估药物疗效的有效手段。其中理解力测试部分通过判断受试者是否根据指令要求做出相应动作实现,是老年人认知功能障碍评估的重要部分,有利于痴呆的早预防早干预。提出了一套神经心理测试中理解力检测的人体姿态估计视频分析方法,基于Openpose深度卷积网络提取人体关键点坐标,然后基于图像形态学处理技术和Faster R-CNN等技术提出了纸张、牙刷等目标物体关键点二维坐标提取方法,并以量表中动作要求建立人体姿态估计数学模型。最后,通过实验对神经心理测试的6个动作进行识别,结果表明,所提姿态估计数学模型和交互动作识别方法能够有效检测人体姿态动作指令及人与纸张的交互指令。

    Abstract:

    Neuropsychological tests can objectively evaluate the severity of cognitive impairment, which is an effective means to detect disease progression and evaluate drug efficacy. Comprehension test is an important part of cognitive impairment assessment of the elderly, which performs assessment by whether the subjects make accurate actions according to the instructions. It is also conducive to the early prevention and early intervention of dementia. A video analysis method of human posture estimation for comprehension detection in neuropsychological testing is proposed. The coordinates of key points of human body are extracted based on OpenPose. Then, based on the image morphology processing technology and Fast R-CNN, a two-dimensional coordinate extraction method is proposed for the key points of the specified target objects such as paper and toothbrush. Also, the mathematical model of human posture estimation is established. Finally, six actions of neuropsychological test are tested to verify the effectiveness. The results show that the proposed mathematical model of posture estimation and interactive action recognition method can effectively detect human posture action commands and interactive instructions.
