AI-102 Question 165
Select 4You are designing an AI solution to monitor customer activity in a retail store using Azure AI Vision Spatial Analysis. The solution needs to detect when people enter specific zones and measure the time they spend in those zones. Which steps should you take to achieve this using Azure AI Vision Spatial Analysis?
- A
Define zone polygons in your spatial analysis configuration to represent the areas of interest.
- B
Ensure the input video feed is pre-processed to remove all moving objects for accurate detection.
- C
Enable the 'Zone occupancy' and 'Dwell time' capabilities in your spatial analysis model.
- D
Deploy the spatial analysis model to an Azure IoT Edge-enabled device for local processing.
- E
Configure notifications in the spatial analysis pipeline to alert when a person enters or leaves a zone.
Show answer and explanation
Correct answers: A, C, D, E
Explanation
To detect the presence and movement of people in specific zones using Azure AI Vision Spatial Analysis, you need to define zones, enable relevant capabilities like 'Zone occupancy' and 'Dwell time,' and deploy the model to an Azure IoT Edge-enabled device for real-time processing. Additionally, setting up notifications helps to act on detected events promptly. Pre-processing the video feed to remove moving objects is unnecessary as the model is designed to handle such input directly.
- A. Correct.
Defining zone polygons is essential as it allows the spatial analysis model to recognize the areas of interest where presence and movement of people should be monitored.
- B. Incorrect.
Pre-processing to remove moving objects is not required because the spatial analysis model is designed to detect and analyze moving objects, such as people, directly in the video feed.
- C. Correct.
Enabling 'Zone occupancy' and 'Dwell time' capabilities allows the model to monitor when people enter a zone and measure the time spent in those zones.
- D. Correct.
Deploying the spatial analysis model to an Azure IoT Edge-enabled device is necessary for local processing of the video feed in real-time, especially for scenarios requiring low latency.
- E. Correct.
Configuring notifications is an optional but useful step to alert when specific conditions, such as entering or leaving a zone, are met. This ensures the solution can act on detected events in real-time.
