Embodiment Construction

[0112] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0113] The invention provides a set of road multi-sensing data vehicle-mounted acquisition system, which can record the dynamic multi-sensing and multi-angle data of the driving environment and various traffic elements in real time during the driving process of the vehicle.

[0114] The schematic diagram of the composition and hardware connection of the road multi-sensor data vehicle acquisition system is as follows: figure 1 As shown, the road traffic multi-sensing data vehicle acquisition system includes multiple cameras, a function-integrated chip box, a master control computer, multiple slave computers, and antennas. Multiple cameras can be placed on the roof in two ways according to user needs: placement mode 1 is fixed on the roof by a fixed bracket, the angle between the optical axes between adjacent cameras is 45°, and the mul...

Abstract

The invention provides a multi-sensing-data space-time synchronization method and a road multi-sensing-data vehicle-mounted acquisition system. The invention proposes the multi-sensing-data space-time synchronization realization method, and the multi-sensing-data space-time synchronization refers to one-to-one alignment of a plurality of paths of video data and GPS position data of a driving vehicle in a time dimension of a single frame of data and a space dimension of different acquisition devices. At the same time, the invention also discloses the vehicle-mounted system of road traffic environment multiple sensing data. The system is capable of real-time recording of multiple sensing data of a road traffic environment of the driving vehicle, such as the plurality of paths of video data and the GPS position data of the driving vehicle. The disorderly multiple sensing data acquired by the acquisition system can only be used alone because incapable of interaction with different kinds of data. However, the multiple sensing data which undergo the space-time synchronization is capable of reproducing driving scenes in a seamless transition manner so that the system is capable of providing comprehensive and objective real data and offline simulation verification data for hot researching problems such as visual scene understanding and environment cognition of unmanned vehicles and the like.

Description

technical field [0001] The invention relates to technical fields such as signal processing, computer vision, and road traffic environment, and in particular to a multi-sensing data time-space synchronization method and a road multi-sensing data vehicle-mounted acquisition system. Background technique [0002] The collection of road traffic environment data is the basis of various researches in the field of transportation, and the accurate collection technology of traffic data is an eternal research topic. As an important research project in the field of transportation, unmanned vehicles are "vehicle-environment" closed-loop systems integrating environmental cognition, decision-making planning and automatic control functions. It has the ability to identify the traffic environment and realize the autonomous driving of vehicles. However, with the deepening of research on unmanned vehicles, some related problems have gradually surfaced. The only way to verify the correctness of...
