Guide Line Transition Interpolation for Smooth Navigation Refreshes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing navigation systems experience abrupt jumps in guide lines during periodic refreshes, leading to a suboptimal display experience.
Innovation Solution
A method and apparatus that pairs positioning points on consecutive guide lines to generate a transition guide line by concatenating intermediate points, which is then displayed between refresh intervals to smooth the transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide line is automatically refreshed periodically, then navigation information is updated, but obvious jump occurs in guide lines displayed at adjacent moments
Solution Approach 1:
The patent pre-calculates and stores multiple historical guide lines (first guide line, second guide line, third guide line) before the refresh moment. These pre-computed guide lines are ready for immediate display during the refresh transition, eliminating the need for real-time calculation and ensuring smooth visual transition without jumps.
Solution Approach 2:
The patent introduces intermediate guide lines (second guide line) that serve as transition elements between the first guide line (before refresh) and the third guide line (after refresh). These intermediary guide lines provide a visual bridge that smooths the transition and eliminates abrupt jumps during the periodic refresh.
2Speed
If guide line is displayed with high refresh frequency, then animation smoothness is improved, but display fineness may be compromised
Solution Approach 1:
The patent divides the guide line display into multiple discrete segments (first guide line, second guide line, third guide line) corresponding to different time moments. Each segment is carefully calculated and displayed in sequence, allowing high refresh frequency while maintaining precision through discrete, pre-computed segments rather than continuous approximation.

AI summary
A guide line display method includes: obtaining a first guide line generated at an ith moment and a second guide line generated at an (i+1)th moment; pairing positioning points on the first guide line and the second guide line to obtain k matching point pairs; generating a transition guide line by concatenating k intermediate points of the k matching point pairs, the transition guide line being a guide line that transitions from the first guide line displayed at the (i+1)th moment to the second guide line displayed at an (i+2)th moment; and displaying the transition guide line between the (i+1)th moment and the (i+2)th moment.
