A Lightweight Object Detection Network for Real-Time Detection of Driver Handheld Call on Embedded Devices

Abstract EN

It is necessary to improve the performance of the object detection algorithm in resource-constrained embedded devices by lightweight improvement.

In order to further improve the recognition accuracy of the algorithm for small target objects, this paper integrates 5 × 5 deep detachable convolution kernel on the basis of MobileNetV2-SSDLite model, extracts features of two special convolutional layers in addition to detecting the target, and designs a new lightweight object detection network—Lightweight Microscopic Detection Network (LMS-DN).

The network can be implemented on embedded devices such as NVIDIA Jetson TX2.

The experimental results show that LMS-DN only needs fewer parameters and calculation costs to obtain higher identification accuracy and stronger anti-interference than other popular object detection models.
