Photo mode is ideal for capturing objects where high accuracy and detail are crucial, or if you do not have access to a LiDAR sensor. This mode utilizes photogrammetry, a technique that involves taking a series of standard photos from various angles. These photos are then uploaded to a more powerful computer, which processes them to create a detailed 3D reconstruction of the object.
Choosing your subject
Pro Tips for Capturing with Polycam
-
Surface Detail and Texture: Your object should have plenty of surface detail and texture for the best results. Patterns, artwork, and organic surfaces are particularly effective.
-
Lighting: Even, diffuse lighting is crucial for a successful capture. For objects that are reflective or shiny, try to diffuse the lighting as much as possible to reduce glare.
-
Object Movement: If the object is rigid, you can move it during the session by flipping or rotating it. Ensure you toggle the “Object Masking” option to on before processing if you move the object.
-
Avoid the following:
- Reflective and blank surfaces, as they can interfere with the capture quality.
- Mirrors. If your capture includes a mirror, cover it with paper and create a scribble pattern on the paper to avoid reflections.
- Thin, hairlike structures, which may not capture well.
How to capture
-
Capture from Multiple Angles: Photo Mode requires images of your subject from many different perspectives. Ensure you capture your subject from all angles, including above, below, and from various sides. The more perspectives you provide, the better the capture quality.
-
Maintain Overlap: Aim for at least 50% overlap between your photos to help the system accurately register them. It’s not necessary for every photo to cover the entire subject; focusing on detailed areas with close-up shots can enhance the overall capture.
-
Use Video for Efficiency: While photos provide the highest resolution, you can use your phone's Slo-Mo video feature to capture quickly. This method allows you to collect hundreds of “photos” in just a few seconds.
-
Upload Your Video: To create a 3D model from your video, click or tap Create Capture, then select Create a 3D model.
Auto vs. Manual Shutter
Photo Mode offers two shutter settings to optimize your captures: Auto and Manual.
-
Auto: With Auto mode, you only need to tap the capture button once. The app will automatically decide when to take photos based on your movement. For capturing a physical space, we recommend using Auto during a single recording session. This approach ensures that images are captured sequentially, which can lead to improved results.
-
Manual: Manual mode allows you to tap the capture button to take individual frames at your discretion. This setting provides greater control over when each photo is taken. You can combine Manual and Auto settings within the same capture session. For instance, you might use Auto for the majority of the session and add Manual photos for specific details.
