We want to convert a MS Visual Studio C++ program with OpenCV (Version 2.4.6) to either TMS320C6748 or OMAP-L138's embedded code. The required OpenCV functions are: findContours; GaussianBlur; cvtColor; Canny; dilate; erode; contourArea; approxPolyDP; matchTemplate; cvCaptureFromCAM; imread; and VideoCapture. Some OpenCV complementary functions are: resize; getRotationMatrix2D; warpAffine; and RotatedRect.
At the moment I have the following questions:
- Considering development time (i.e. converting OpenCV to embedded), which DSP processor would be the best choice the TMS320C6748 or the OMAP-L138?
- In the case of the OMAP-L138 and considering the OpenCV requirement, does the ARM core introduce a bottleneck in the program execution? We are looking for real time video analysis and low power consumption.
- Is it strictly necessary to work with Linux when using the OMAP-L138 (some E2E's forums talk about using Linux in their cases)? If true, what are the main advantages of doing this?
- We are using a USB Web Cam with a resolution of 480x640. Access to the camera is through OpenCV. Could you recommend us a camera for working with the system prototype? Is it required to write a driver?
Thanks,
