A Vehicle Acquisition System of Multi-source GPS Data and Monocular Image

Abstract

The invention provides a vehicle-mounted collection system for multi-source GPS data and monocular images, and relates to vehicle-mounted embedded system technology. The invention includes GPS, differential GPS, monocular camera module, embedded computer and memory; the embedded computer is provided with a USB3.0 hub for connecting multi-source GPS and monocular camera module; the memory adopts M.2 interface solid state The hard disk is the main mode, and the SATA3 interface solid-state hard disk is the auxiliary mode; the processing software installed in the embedded computer starts the corresponding number of signal acquisition threads according to the number of GPS and differential GPS, and starts a separate camera image acquisition thread and user interaction thread, The threads are processed in parallel. The embedded computer of the present invention has the advantages of small size and low power consumption, and the USB interface has excellent versatility and replaceability, solves the problem of insufficient storage space of the embedded computer, and realizes synchronous acquisition of multi-source GPS data and monocular images .

Description

technical field [0001] The invention relates to the fields of information technology and embedded system technology, in particular to a vehicle-mounted collection system for multi-source GPS data and monocular images. Background technique [0002] The on-board acquisition system is an integrated embedded system with functions of acquisition, recording, and calculation, which is used for vehicle, transportation, automation and other related disciplines for the data generated during the operation of the vehicle and the equipped sensors. Because monocular vision has the advantages of simple structure and low cost, multi-source information fusion technology can realize the complementarity of multi-source information and improve the accuracy and reliability of environmental perception by correlating and integrating similar or different feature information. Carry out research and development of key technologies based on monocular visual environment perception and multi-source info...
