Hi, I've been reading about the program your working on,Chimera, and was wondering if it had the functions I need for a project I'm working on: I'm trying to create a 3D graph to represent an image and the distance that image is away from a source. I was looking at your Chimera program to do this. I was wondering if your Chimeraprogram had the necessary functions I needed to do this? If so, can you point me in the right direction on what the functions I need would be? Below I described a little more in depth of what I'm trying to do. First, I'll give you a little detail on our overall project so you have a better idea of what I'm dealing with. We're trying to measure the distance of an object using two cameras. Two identical cameras are positioned near each other with a separation distance and focusing angle. The Image-Processing Computer applies filters to conform the images so that meaningful features stand out in contrast to non-meaningful features (i.e. shadows, textures, glare, and reflections). The computer uses a vast array of image-processing algorithms to find key features in the images. Cross-correlation is performed between the features in both images to determine the line-of-site angle and separation distance. With that found, triangulation is performed to determine the distance that an object(s) is away from the cameras. ------------------------------------- Now, once we have determined the distance, we want to have a 3D graph display the object's distance away from the camera (part where I'd like to use Chimera), as they come into focus. (i.e. The graph will be continually updating at 10 frames/sec along with the cameras) I have attached a general 3D graph .bmp file to show you kinda what I'm looking for. (Obviously, the graph won''t portrude negative as the .bmp file since the camera only look in one direction) What I'm thinking is I will basically take in two parameters. 1) The coordinates of the edge detected (horizontal and vertical pixel location). Edges won't be detected in the entire area ( i.e. a wall focused in too closely will ideally show no edges). The graph will only be concerned with areas that edges were detected. 2) The other parameter that needs to be taken in is the computed distance from the cameras of the detected edge. This is the parameter that will determine how far the graph protrudes out in the z direction. Ideally, I would like for portions of the graph to change colors corresponding to a certain distance detected (i.e. 0-1 feet red, 1-2 feet orange, etc...). Also, something that isn't needed (but would make the graph look a lot better), is if I could use some interpolation functions so areas that were encompassed by edges would protrude out, too, instead of just the edges. Sorry about the length of this email. I just wanted to give you a good idea of what I'm looking for. I also attached a picture (" picture2.bmp") that had gone through an edge detection program. The white lines are detected edges. Everywhere else in the image now has a pixel intensity of 0. I'm looking for a library to help me accomplish all or most of these things listed with the 3D graph. I am an amateur at computer programming , so the simpler the better (I'm an electrical engineering major, we don't get a chance to learn too much about how to program). Anything you can help me with I would really appreciate. Thanks a lot for your time and I'll look forward to your response. -- Sincerely, Jacob Chrzanowski Electrical Engineering Student, NDSU jmchrz@gmail.com (701) 866-3120
