Embodiment Construction

[0114] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0115] The present invention mainly combines the advantages of multi-sensor diversity, adopts the receiving time stamp as the time stamp of the data frame, unifies the time information of various sensors before performing multi-sensor data fusion, and realizes the real-time monitoring of traffic environment information of intelligent vehicles. Acquisition integrates scattered multi-source fragmented information into a frame of closely related information data, and corrects the delay in sending and receiving information at high transmission rates to generate visualized real-time data display to meet the real-time requirements of data display.

[0116] Such as figure 1 , the front local driving environment perception system of the present invention includes a front-e...

Abstract

The invention provides a system and a method for sensing a local driving environment in the front. The system comprises a front-end data acquisition system and a background server data processing system, wherein the front-end data acquisition system comprises a vehicle-mounted camera, a laser radar and vehicle interior sensing equipment, wherein the camera is used for sensing pedestrians and lane lines in front of a running vehicle; the laser radar is used for sensing and extracting information of obstacles such as a vehicle in the front; the vehicle interior sensing equipment is used for acquiring running state parameters of the vehicle. Three data transmission types of MyProtocolCarData, MyProtocolCameraData and MyProtocolUrgData are defined, a data format is unified for encoding, and then camera information data, laser radar information data and vehicle interior information data are transmitted to a background server for decoding to integrate three kinds of sensor data into a frame of complete local traffic environment information which is saved into a data storage system, and a function for analyzing and visualizing data of the local driving environment in the front is provided. By real-time and efficient sensing of the local driving environment in the front, rear-end collision accidents are reduced, and the traffic safety is improved.

Description

technical field [0001] The invention relates to the technical field of driving environment perception, in particular to a front local driving environment perception system and method. Background technique [0002] At present, with the help of automatic control, artificial intelligence, computer vision and other technologies, smart cars realize information collection, data processing, and data fusion, and realize functions such as autonomous overtaking, obstacle avoidance, recognition of traffic signs, lane lines, and autonomous parking. The real-time and efficient perception of the local driving environment ahead is an important part of the safe driving assistance system, and the fundamental guarantee for reducing rear-end collision accidents and improving driving safety. The unmanned vehicle "smartV" jointly developed by Wuhan University and Chery is equipped with various sensing devices such as electronic compass, laser scanner and camera, and has independently modified th...
