Vehicle-mounted data collection system of multi-source GPS data and monocular images

Abstract

The invention provides a vehicle-mounted data collection system of multi-source GPS data and monocular images, and relates to the vehicle-mounted embedded system technology. The vehicle-mounted data collection system comprises a GPS, a differential GPS, a monocular camera module, an embedded computer and a memory; the embedded computer is provided with a USB3.0 concentrator used for connecting with a multi-source GPS and the monocular camera module; the memory adopts a mode in which M.2 interface solid state hardware is main and SATA3 interface solid state hardware is auxiliary; and processing software installed in the embedded computer starts a corresponding number of signal collection threads according to the number of the GPS and the differential GPS and starts a single camera image collection thread and a single user interaction thread, and the threads are processed in parallel. The embedded computer of the vehicle-mounted data collection system has the advantages of low power consumption, the USB interface has excellent universality and replaceability, the problem of insufficient storage space of the embedded computer is solved, and the synchronous collection of the multi-source GPS data and the monocular images is realized.

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...
