Road Pit hole detection using OpenCV - Part 1
Introduction
This article is about detecting pit holes on road.It analyses images identifies craks & distresses on roadBackground
My friend is a highway engineer. Worked in Chennai,India.He did lot of manual work on identifing pit holes.Survey is done manually employing engineers Measure distresses based on length, depth and areaJava code sniplet
FeatureDetector blobDetector = FeatureDetector.
create(FeatureDetector.ORB); blobDetector.detect(srcImgMat, matOfKeyPoints); System.out.println("Detected " +
matOfKeyPoints.size() + " blobs in the image");After that i have identified the keypoints, i have plotted them in the original image We take a video of the road, we will apply same logic to all the frame. This will be done using VideoCapture api of opencv. Then we calculate the SQFT of the distress/crack. Then we calculate the cost of filling the distress. This would reduce rework of laying road and it will last longer. We can make use of tensorflow to identify the cracks. I will post an article in part 2 article.
Hope you liked it

Webgl - SceneJS
For making secenejs and webgl work together the following steps will be followed. This is an example.
1) Goto this URL http://sketchup.google.com/3dwarehouse/details?mid=6577336fbb374e1ee94eb85263ec76bc&prevstart=0
2) Download model google sketchup
3) Open model in google sketchup
4) File --> Export --> 3D Model
5) A file with extension kmz will be saved
6) Extract the file with 7 zip
7) Navigate to the model folder
8) A file with extension .dae will appear
9) Open the file in any text editor(Notepad,Notepad++)
10) In explorer navigate to C:\Users\Raja Sekhar\Downloads\xeolabs-scenejs-utils-ff97cdf\xeolabs-scenejs-utils-ff97cdf\tools\collada-translator
11) Copy the dae file txt and click on translate save it with .js
12) Include the file in html

The stored procedure expects a parameter error
When executing your stored procedures through Sybase ace driver, you may get an error the stored procedure expects as a parameter even your passing the parameters
Ex getEmployes
assgin parameters to command
execute the command.
you may get an error saying no parameters found for the stored procedure
To resolve this error
you need to assign stored procedure as getEmployees ?,?,? (No of parameters that stored procedure takes)

Executable UML
Executable UML is a different approach rather than standard UML process.
and is the evolution of the Shlaer-Mellor method[3] to UML
The executable UML consists of
Domain Chart
Class Diagram
Statechart diagram
Action language
Model testing and execution
Model compliation
Using executable UML we can model Platform independent systems. We can verify the system wheather it achieves the specified goals or not.
