How to use TMS320DM8148 for object recognition? [Copy link]

I checked the official cases of DM8148, and there are cases of DM8148 using DSP and OpenCV for face recognition. May I ask, 1. Can I use openCV to identify vehicles? What is the accuracy and rate of recognition? Are there any requirements for image resolution, frame rate, etc. (If the resolution is high, I am worried that the DSP operation cannot reach real-time) 2. Using MD8148, are there other target recognition solutions? For license plate recognition, the basic idea is the same as that for face recognition. You can ask the algorithm supplier for a set of DSP algorithm evaluation library, put it under DSP for frame-by-frame processing to get the results, and then send it back to ARM for use. Based on the experience of other platforms, the 8148 DSP is not good enough for license plate recognition. The analysis of a single frame of 720P image is estimated to take 1000 milliseconds. Of course, there is still room for optimization, such as improving the implementation of the algorithm library and dividing part of the operation to the ARM side, but it is more difficult. Currently, mcfw does not directly support USB cameras. You need to use v4l2 to collect data first, and then pass it to the mcfw framework from ARM Linux through hostin LINK.
