3D Map Tiling Direction Control for Higher Encoding Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for encoding 3D occupancy grid maps, such as those used in egocentric 3D occupancy grid maps, suffer from reduced encoding efficiency due to a fixed tiling direction, which leads to lower correlation and prediction accuracy between frames.
Innovation Solution
The tiling direction is adjusted based on the change in the relative position between the reference object and the peripheral object, allowing for the generation of 2D tiling images that are then encoded, thereby improving encoding efficiency.

1Productivity
If a fixed tiling direction is used for encoding 3D occupancy grid maps, then the encoding process is simple, but the encoding efficiency is lowered due to reduced correlation and prediction accuracy between frames
Solution Approach 1:
The patent applies the dynamics principle by making the tiling direction adjustable rather than fixed. The tiling direction setting unit dynamically changes the tiling direction based on the movement direction of the reference object, allowing the encoding system to adapt to different scenarios and maintain high correlation between frames, thereby improving encoding efficiency without excessive complexity
Solution Approach 2:
The patent applies parameter changes by modifying the tiling direction parameter according to the movement characteristics of the reference object. By changing this parameter based on movement direction information, the system optimizes the correlation between adjacent frames in the encoded sequence, improving prediction accuracy and overall encoding efficiency
2Reliability
If the tiling direction is adjusted based on relative position changes, then the correlation between frames is maintained, but the processing complexity increases
Solution Approach 1:
The system dynamically adjusts the tiling direction based on the movement direction of the reference object, making the tiling process adaptive rather than static. This dynamic approach maintains high correlation between frames by aligning the tiling direction with the actual scene changes, improving reliability of the encoding
Solution Approach 2:
The patent implements feedback by using the movement direction information of the reference object to determine the optimal tiling direction. This feedback mechanism ensures that the tiling direction is continuously optimized based on scene dynamics, maintaining high frame correlation while managing processing complexity through intelligent decision-making
