Object Following with Deepstream

mugimeshi · October 17, 2021, 10:58pm

Hi guys, I’m new at this things and working on a project like this:

I will use Deepstream and NVIDIA’s TAO models for License Plate detection. How can I have Jetracer follow the this car, if the License Plate Detection process result and the License plate given as input to the program match?

Thank you for giving a time.

Hi,

First, please deploy a License Plate Detection with Deepstream.
After locating the License Plate that matched with input, you should also have the bounding box of the car.

Then you can use jetbot sample but switch the central object with the matched bounding box for your use case:

    "In this notebook we'll show how you can follow an object with JetBot!  We'll use a pre-trained neural network\n",
    "that was trained on the [COCO dataset](http://cocodataset.org) to detect 90 different common objects.  These include\n",

    "* Person (index 0)\n",

    "and many others (you can check [this file](https://github.com/tensorflow/models/blob/master/research/object_detection/data/mscoco_complete_label_map.pbtxt) for a full list of class indices).  The model is sourced from the [TensorFlow object detection API](https://github.com/tensorflow/models/tree/master/research/object_detection),\n",
    "which provides utilities for training object detectors for custom tasks also!  Once the model is trained, we optimize it using NVIDIA TensorRT on the Jetson Nano.\n",
    "\n",
    "This makes the network very fast, capable of real-time execution on Jetson Nano!  We won't run through all of the training and optimization steps in this notebook though.\n",
    "\n",
    "Anyways, let's get started.  First, we'll want to import the ``ObjectDetector`` class which takes our pre-trained SSD engine."

Thanks.
