DIY spectrometer software

Dear Person Who Can Turn Gibberish v_d=$_(%0) Into a Magic Work Tool, I am making DIY spectrometer and would like to have software for it. If you are familiar with the topic, software should be little more advanced than AspectraMini. Briefly, software should be able to capture images from external webcam (using PC with Win10) and make simple analysis. Basic feature: What for: Observe what is going on and save preliminary spectrum. Software should take live image from the cam. Then user must pre-set region of interest (ROI) (saving pre-set should be available) where all the things will happen. After choosing ROI, software should build the graph intensity vs. pixel number. Graph should be live. Once button pressed, curve is frozen, and another live curve appears – so user can add curves to the graph just by clicking button. After done, the graph should be saved as image (optional), and data from all curves should be saved in one .txt(csv) file like column of pixel number and columns of intensities (must have option). That was an easy part like AspectraMini. Advanced part (must have): What for: This advanced option will allow user to track position of intensity maximum. Upon user request, software take series of images every pre-set amount of time (e.g. 300ms) – until time limit (need to be pre-set) or button press. All same as previous – all curves appear on the intensity vs. pixel graph by adding, not refreshing. Before this process user define second ROI – (e.g. initial ROI was from px10 to px950, and user have curves corresponding that area, and now he choose one more ROI – eg. from px580 to px640 (he still watch the graph with first ROI). In than 2nd ROI software is searching for a pixel number that corresponds to the maximum of intensity and displays it (somewhere not in the graph, perhaps some sort of window beside the graph). While software takes series of images, it should find position of maximum for each image in 2nd ROI and be able to save it in a separate .txt file with a first column with time mark and second column with pixel number that corresponds to maximum intensity. Simultaneously, when the serial process starts, software must create one more separate graph, live updated, where the pixel number with maximum intensity will be plotted over time. Hope this text may help you to evaluate… Thanks for consideration!
