Introduction

In the realm of computer vision and object detection, bounding boxes play a crucial role in identifying and localizing objects within images or videos. Axonsoft alerts, a popular platform for real-time object detection, provides a robust API for sending alerts and notifications. However, when it comes to sending multiple bounding boxes, users often encounter issues with the API. In this article, we will explore the challenges of sending multiple bounding boxes in Axonsoft alerts using GRPC APIs and provide a step-by-step guide on how to overcome these challenges.

Understanding the Issue

When passing multiple bounding boxes as a list, users are often met with a status code 500 error. This error occurs due to the limitations of the Axonsoft API, which expects a single bounding box as a dictionary. However, when passing a list of bounding boxes, the API becomes overwhelmed, resulting in a 500 error.

The Problem with Passing a List of Bounding Boxes

Passing a list of bounding boxes as a dictionary is not a viable solution. When attempting to make the API call, users are met with a 500 error. This is because the Axonsoft API is designed to handle a single bounding box as a dictionary, not a list of bounding boxes.

The Solution: Passing a Single Bounding Box as a Dictionary

To overcome the challenges of sending multiple bounding boxes, users can pass a single bounding box as a dictionary. This approach may seem counterintuitive, but it provides a viable solution for sending multiple bounding boxes.

Step 1: Create a Dictionary for a Single Bounding Box

To pass a single bounding box as a dictionary, users need to create a dictionary with the following keys:

x: The x-coordinate of the bounding box
y: The y-coordinate of the bounding box
w: The width of the bounding box
h: The height of the bounding box

bounding_box = {
    'x': 10,
    'y': 20,
    'w': 30,
    'h': 40
}

Step 2: Make the API Call

Once the dictionary for a single bounding box is created, users can make the API call using the GRPC API. The API call should include the dictionary for the bounding box as a parameter.

import grpc

# Create a channel to the Axonsoft API
channel = grpc.insecure_channel('axonsoft-api-url')

# Create a stub for the Axonsoft API
stub = axonsoft_api_pb2.AxonsoftAPIStub(channel)

# Create a request for the API call
request = axonsoft_api_pb2.Request(
    bounding_box=bounding_box
)

# Make the API call
response = stub.SendAlert(request)

Step 3: Repeat the Process for Multiple Bounding Boxes

To send multiple bounding boxes, users need to repeat the process of creating a dictionary for a single bounding box and making the API call. This can be achieved using a loop or a list comprehension.

bounding_boxes = [
    {'x': 10, 'y': 20, 'w': 30, 'h': 40},
    {'x': 50, 'y': 60, 'w': 70, 'h': 80}
]

for bounding_box in bounding_boxes:
    request = axonsoft_api_pb2.Request(
        bounding_box=bounding_box
    )
    response = stub.SendAlert(request)

Conclusion

Sending multiple bounding boxes in Axonsoft alerts using GRPC APIs can be challenging, but it is not impossible. By passing a single bounding box as a dictionary and repeating the process for multiple bounding boxes, users can overcome the limitations of the Axonsoft API. This approach provides a viable solution for sending multiple bounding boxes and can be used in a variety of applications, including computer vision and object detection.
