Aiming at the problem that mobile cleaning robot needs to identify road accurately and quickly when it operates in photovoltaic plants, a target recognition model of improved DeepLabv3+ to identify the roads within photovoltaic plants is proposed. First, the backbone network of the original DeepLabv3+ model is replaced with an optimized MobileNetv2 network to reduce complexity. Then, the strategy that combines diverse receptive field fusion with depth separable convolution is employed, which enhances the atrous spatial pyramid pooling (ASPP) structure and improves the information utilization of ASPP and the training efficiency of model. Finally, the attention mechanism is introduced to improve the segmentation accuracy of the model. The results show that the average pixel accuracy of the improved model is 98.06%, and the average intersection over union is 95.92%, which are 1.79 percentage points and 2.44 percentage points higher than those of the DeepLabv3+ basic model, and SegNet and UNet models. Furthermore, the improved model has fewer parameters and a good real-time performance, which can better realize the road recognition of mobile cleaning robot of photovoltaic plants.
