    摘要:

    使用單一傳感器進(jìn)行人體跌倒檢測的方法不能充分捕捉動(dòng)作特征,攝像頭在光線(xiàn)較差時(shí)無(wú)法獲得高質(zhì)量圖像,毫米波雷達的點(diǎn)云稀疏性降低了遠距離目標信息的有效性;針對上述問(wèn)題,提出了一種基于雙模態(tài)門(mén)控特征融合的跌倒檢測方法;使用雷達和攝像頭同步檢測,雷達分支根據時(shí)間-距離圖和微多普勒圖獲得融合特征,視覺(jué)分支提取目標的光學(xué)特征;將兩種特征送入門(mén)控融合模塊,根據權重整合特征信息,在輸出層實(shí)現分類(lèi);設計了雷達分支和整體網(wǎng)絡(luò )的相關(guān)實(shí)驗,雷達分支融合方法的平均準確率是91.7%,優(yōu)于單一特征方法;整體網(wǎng)絡(luò )的門(mén)控融合方法的準確率是94.1%,相比特征相加融合和首尾拼接融合方法分別高出3.0%和1.8%;充分表明該方法能夠提升人體跌倒檢測的性能。

    Abstract:

    The method of human fall detection using a single type of sensor cannot adequately capture motion features. The camera cannot obtain high-quality images under poor lighting conditions, and the point cloud sparsity of millimeter-wave radar reduces the effectiveness of remote target information. To solve these problems, a fall detection method based on bi-modal gated feature fusion is proposed. The method uses radar and camera to synchronized detection. The radar branch obtains the fusion feature based on time-distance map and micro-Doppler map, and the visual branch extracts the optical feature of the target. The two features are sent to the gated fusion module, and the feature information is integrated according to the weight to realize fall detection at the output layer. Experiments of the radar branch and the overall network are designed. The average accuracy of the radar branch fusion method is 91.7%, which is better than that of the single feature method. The accuracy of gated fusion method in the overall network is 94.1%, which is 3.0% and 1.8% higher than that of feature addition fusion and fore-tail fusion, respectively. It is fully demonstrated that the method can effectively improve the performance of human fall detection.
