Types of Global Positioning System Surveys

Types of Global Positioning System Surveys

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Area of Science:

Computer Vision
Robotics
Autonomous Driving

Background:

Radar systems have blind spots on high-speed roads, particularly on curves.
This leads to trajectory deviations in filtered data due to missing multi-frame measurements.

Purpose of the Study:

To develop an improved track prediction method for vehicles in radar blind zones.
Enhance trajectory accuracy and reduce scattering of target tracks.

Main Methods:

Utilized high-precision maps to fit lane centerlines and determine off-north angles.
Implemented coordinate system conversion (ENU to vehicle) and set lateral velocity to zero for extrapolated trajectories.
Updated and corrected trajectories, managing both normal and extrapolated paths.

Main Results:

The proposed method significantly reduces trajectory deviations in radar blind zones.
Experimental results demonstrate superior accuracy and convergence compared to traditional methods.

Conclusions:

Combining high-precision maps with track prediction effectively addresses radar blind zone challenges.
The method offers a robust solution for reliable vehicle tracking in complex road scenarios.
