- Abstract:

Convolutional neural networks have achieved great success in visual perception tasks. Its complex network structure makes the model computationally complex, which limits its application in actual terminal scenarios such as autonomous driving. Aiming at the problem of limited computing resources in terminal scenarios, in this paper, we conduct research from two aspects: lightweight deep model design and the model deployment and verification on car-level chips. As for the contradiction between the calculation efficiency of deep models and the detection accuracy, we design a lightweight object detection model based on the center-convolution, enjoying low power consumption and high accuracy model performance. Furthermore, based on the method of quantization aware training, we carried out system-level deployment and verification on car-level chips. We successfully implemented a high-efficiency object detection model on the car-level chips, i.e. tda4, and achieved good performance in autonomous driving scenarios.
