Description
Technical field
The present invention relates to a kind of intelligent travelling crane early warning system prototype based on multinuclear heterogeneous processor
Background technology
In order to realize the main purpose of automotive safety auxiliary driving technology research, it is necessary to by various on vehicle
Sensor (passive infrared camera, industrial camera, microwave radar, laser radar etc.) grasps this car, road and surrounding vehicles
The information such as situation, auxiliary driver increases the ability of environment sensing, and for it provides early warning signal.
The information for merging multisensor can obtain the performance that single sensor is difficult to obtain, and be mainly reflected in and improve letter
Breath redundancy and complementarity.The performance advantage that information fusion has is mainly reflected in：Improve the confidence level and target of information
Detectivity, expands the hunting zone in time and space, reduces reasoning fog-level, improves detection performance, increased
The dimension of target feature vector, improves spatial resolution, enhances system survivability and adaptivity.
Heterogeneous Computing is primarily referred to as using the calculating of the computing unit composition system of different type instruction set and architectural framework
Mode.The common computing unit classification processor such as including CPU, GPU.Heterogeneous Computing obtains more concerns in recent years, mainly
Because the traditional approach that computing capability is improved by lifting cpu clock frequency and number of cores encounters radiating and energy consumption bottle
Neck.Although and the dedicated computing unit working frequency such as GPU is relatively low, with more interior check figures and computation capability, bulking property
The ratio and performance/power dissipation ratio of energy/chip area are all very high, are but far from being fully used.
The design of CPU allows it to be relatively good at treatment irregular data structure and uncertain access mode, Yi Jidi
Reduction method, branch's intensity code and single-threading program.This kind of program task possesses the instruction scheduling of complexity, circulation, branch, patrols
Collect the step such as judgement and execution.And GPU is good at processing rules data structure and predictable access mode.The length of both set
Place, the optimization of overall performance is reached with Heterogeneous Computing.
Polycaryon processor refers to integrated two or more complete computing engines (kernel) in one piece of processor, is now located
Reason device can support the multiple processors on system bus, and all bus control signals and command signal are provided by bus control unit.
The utilization of polycaryon processor provides technical guarantee for multi-sensor information fusion.
At present, automobile autonomous driving system is mainly made up of Driving control subsystem and Context awareness subsystem, and environment is known
Small pin for the case system recognizes that two subsystems are constituted by road mark line identification and front vehicles, and Driving control subsystem is determined including behavior
The main modulars such as plan, conduct programming and operational control.But function is separated between camera, is unfavorable for playing the synthesis of many mesh cameras
Effect, can neither detect multiple target, and target depth information can not be provided again；It is also unfavorable and camera is separated with other sensors
In the fusion of multisensor.
The invention provides a kind of intelligent travelling crane early warning system prototype based on multinuclear heterogeneous processor, using multisensor
Vehicle front condition of road surface and running data are obtained, using multinuclear heterogeneous processor, information fusion, then profit is carried out to multisensor
With control unit, actuator and warning device are controlled, and use embedded real-time operating system, so as to greatly reduce car accident
Occur.
