If you’re using an iPhone or iPad with a LiDAR sensor and want to ensure it’s functioning correctly, there are a few checks you can perform. LiDAR sensors are essential for accurate 3D scanning and depth mapping in Polycam, so it’s important to verify that the sensor is working properly.
Signs That Your LiDAR Sensor May Be Malfunctioning
- Missing White Guidelines: When using LiDAR in Polycam, if you notice that the white guidelines are missing and the screen shows only a blue background, this may indicate that the LiDAR sensor is not functioning as it should.
- Slow or No Object Detection: If your LiDAR sensor is not quickly detecting objects or accurately measuring distances, it might be experiencing an issue.
How to Test Your LiDAR Sensor
1. Use the Measure App: A quick way to test your LiDAR sensor is by using the Measure app, which comes pre-installed on iPhones and iPads with LiDAR support.
- How to Access the Measure app and check LiDAR integrity:
- Open the Measure app on your device.
- Move your iPhone or iPad around to scan your surroundings.
- The app should quickly detect objects and provide accurate measurements.
- You should see distance markers and clear object recognition.
2. Perform a Test Scan in Polycam: You can also test the LiDAR sensor directly in Polycam by starting a LiDAR-based scan. If the scan shows accurate depth information with visible white guidelines and quick object detection, the sensor is likely working as expected.
What to Do if Your LiDAR Sensor Isn’t Working
- Check for Obstructions: Ensure the LiDAR sensor on your device isn’t blocked by a case or any debris.
- Restart Your Device: Sometimes restarting your iPhone or iPad can help resolve temporary sensor issues.
