[D]Options for Real time object detection and localization on a raspberry pi 3 (ideal speed 10fps)? • r/MachineLearning

I recently started looking into object detection for a project of mine and was wondering if am missing something to get stuff off the ground. I want to implement a real time object detection system on a raspberry pi 3 for surveillance of an open spaces for eg a garden. I have already tried a few available solutions. I don't need to detect many classes(only 3 person,dog, bicycle) so maybe the fastest option can be retrained with fewer filters and parameters thereby decreasing the total compute time. Installed default darknet tested YOLOv2 and YOLO runs on a raspberry pi3 each frames runs for approx 450 secs for each image.
