AI-102 Question 169
Select 3You are tasked with designing an Azure AI Vision Spatial Analysis solution for a retail store to monitor foot traffic and detect when customers enter restricted areas. Which of the following actions should you take to ensure the solution detects the presence and movement of people accurately?
- A
Configure the spatial analysis module to define zones of interest and associate them with specific events.
- B
Enable the Azure AI Vision service to send raw video footage to Azure Blob Storage for processing.
- C
Train a custom machine learning model to classify objects in the video feed before passing them to the spatial analysis module.
- D
Specify the detection mode for tracking people and enable event triggers for zone entry and exit.
- E
Ensure that the video feed is streamed in a supported format and resolution compatible with Azure AI Vision Spatial Analysis.
Show answer and explanation
Correct answers: A, D, E
Explanation
To accurately detect the presence and movement of people using Azure AI Vision Spatial Analysis, you must configure zones of interest, specify detection modes, and ensure video feed compatibility. These steps leverage the built-in capabilities of the service. Sending raw video footage or training custom models is unnecessary, as the service is designed to process live video streams using prebuilt models tailored for spatial analysis tasks.
- A. Correct.
Configuring zones of interest and associating them with specific events is a key feature of Azure AI Vision Spatial Analysis. This allows the system to monitor designated areas and respond to detected movements.
- B. Incorrect.
Sending raw video footage to Azure Blob Storage is not required for spatial analysis. The service processes video streams in real time, not stored footage.
- C. Incorrect.
Training a custom machine learning model is unnecessary because Azure AI Vision Spatial Analysis already provides prebuilt models specifically designed for detecting and tracking people.
- D. Correct.
Specifying the detection mode for tracking people and enabling event triggers is essential for monitoring movement and detecting entry or exit in defined zones.
- E. Correct.
Ensuring the video feed is in a supported format and resolution is critical for the accurate functioning of Azure AI Vision Spatial Analysis.
