Readme for Bridge Laboratory Exercise
There are two versions of the bridge laboratory exercise provided at this web site. The objectives for this laboratory exercise are to:
· Use color thresholding on a color image to pick out certain objects in that image,
· Use a camera in a fixed known location to measure the three-dimensional location of specific objects segmented in the image based on a variation of orthographic projections, and
· Use three-dimensional real world coordinate measurements to calculate the velocity of an object.
Laboratory exercise 1 allows the student to gain experience with object segmentation, labeling and tracking in multiple image frames for determining the object's velocity. Code developed in Matlab 6.1 is provided for translating the two-dimensional object locations to three-dimensional real world coordinates. To use this exercise in your classroom setting:
1) Select the directory http://campus.mst.edu/smartengineering/EducationalResources/LaboratoryExercise,
2) Download the web camera image frame images (tagged image format) of the moving truck from the subdirectory http://campus.mst.edu/smartengineering/EducationalResources/LaboratoryExercise/ImageData,
3) Change directories to http://campus.mst.edu/smartengineering/EducationalResources/LaboratoryExercise/Version1
4) Download the description for Laboratory Exercise 1,
5) Download the Matlab code (TwoDtoThreeD.m) provided for performing the two-dimension to three-dimension coordinate transformation and
6) Download a sample student solution from the subdirectory http://campus.mst.edu/smartengineering/EducationalResources/LaboratoryExercise/Version1/SampleSolution.
The sample student solution includes the Matlab code for performing the specified tasks.
Laboratory exercise 2 allows the student to gain experience with object segmentation, labeling and tracking in multiple image frames for determining the object's velocity. This exercise also gives students the opportunity to develop their algorithm variation of orthographic projections for coordinate transformation. To use this exercise in your classroom setting:
1) Select the directory http://campus.mst.edu/smartengineering/EducationalResources/LaboratoryExercise,
2) Download the web camera image frame images (tagged image format) of the moving truck from the subdirectory http://campus.mst.edu/smartengineering/EducationalResources/LaboratoryExercise/ImageData,
3) Change directories to http://campus.mst.edu/smartengineering/EducationalResources/LaboratoryExercise/Version2
