Introduction
Introduction
Robust estimation of stereo disparity in bad weather
- Existing stereo matching algorithms have difficulty to calculating disparity in various environment
- Developed robust matching algorithm using geometrical features about surface of road and dynamic modeling
Development of stereo matching algorithm
- Accuracy : 95.28%
- Dense Registration : 100%
Development of stereo matching algorithm in bad weather
- 2.9sec(12 it) ※ Baseline : 12cm, CPU Intel i7-based

Development of robust and dense stereo matching method
Vertical-Horizontal Stixel aggregation
- Obstacle detection on the ground using disparity => separating ground, obstacle, background => removal information of ground and background
- Vertical stixel(connecting disparity label with same-value) occurs, when specific object exists
- Vertical stixel(horizontal disparity label with same-value) appears on the ground part
- Reducing error with stixel correction using relaxation labeling
Superior our algorithms
- Offer various context recognition service from captured real-time depth information around vehicle
- Dynamic obstacle detection from depth image
- Detect safety region from experimental result
