Abstract
The recognition of road targets represents one of the central technological advancements within intelligent transportation systems, aimed at addressing the critical problem of urban congestion. In light of this, the present paper introduces a road target recognition algorithm, MOLO, specifically designed to navigate complex traffic environments, and subsequently deployed to facilitate detection via mobile devices. MOLO comprises two distinct components: a feature extraction network and a feature fusion network. The former of which, builds upon the structure of SSD network, integrates the lightweight receptive field expansion module RFB-L, whilst the latter introduces a pixel and channel information fusion module termed Fusion, thereby enabling the fusion of both shallow and deep features, ultimately enhancing the overall detection efficacy of the model. The model transformation process uses quantization and inverse quantization strategies between fixed-point and floating-point numbers, significantly reducing the number of parameters, all whilst preserving the accuracy of the detection performance on mobile devices. Experiments show that MOLO, when deployed to mobile, achieves an inference speed of 23.66ms and with 98.96% detection accuracy on the homemade road dataset Hohhot_city, and also shows superior performance in actual road detection.
