Abstract:

To address the issue of feature loss that occurs during the extraction and transmission of target features in 3D object detection tasks using point cloud data, this study proposes an object detection method based on cross-module attention. This method incorporates a channel attention module and a spatial attention module to enhance the crucial feature information. Through feature transformationthe features from different stages of the attention module are connected to mitigate the loss of features during the extraction and transmission process. To tackle the problem of inadequate detection performance in target detection networks for objects of different scales, a cross-scale feature extraction and fusion method is introduced. This method enhances the network’s ability to acquire multilevel features by employing multi-scale feature extraction and fusion techniques. Experimental results demonstrate that the proposed method achieves state-of-the-art performance while maintaining a real-time inference speed of 33 Hz.
