| Abstract: | Target detection is a key technology of target location based on vision. Aiming at the environmental sensitivity of the existing wheel detection methods,this paper proposes a wheel detection model integrating RNN and Faster R-CNN named FusionRNN. Leveraging RNN to deal with temporal information and CNN to extract the recessive characteristics in the spatial domain, it can improve the real-time performance, reduce the number of parameters, and make the model more expressive.At the same time, it has the ability to analyze the semantic relationship between serialization vectors and recognize the geometric features of wheels. The model can accurately detect the wheel in the three-dimensional point cloud scanned by the LiDAR, provide the vehicle position information for the intelligent manipulator used to grab the vehicle to the designated parking space, accurately obtain the vehicle's center of gravity, and realize the safety, rapid capture and storage of the vehicle. |
