The City of Los Angeles, Bureau of Engineering maintains over 11,000 miles of sidewalks. When a segment of sidewalk does not settle evenly or has been raised up by tree-root growth, the sidewalk becomes uneven. This can create pedestrian hazards. In addition, the City is obligated to ensure that its sidewalks conform to Federal ADA standards, which limit the extent to which a sidewalk may slope.

ABSTRACT / DESCRIPTION: This is the forth term of a multi-year project. In last term, a rover has been successfully fabricated. Now, the rover is capable of 1) moving autonomously, 2) measuring crossing slopes and running slopes, 3) collecting GPS data, and 4) taking photo images. In this term, we will focus on developing various software that 1) lenders the photo images with slope data and GPS data, (in office) 2) processes images such as object segmenting and texture processing, 3) assists field crew while they are collecting data in the field (i.e. a user-friendly mobile app/web app). 4) In addition, develop a database schema and back-end server to store and manage raw data.
