Equipment

Choice of camera

Using a 360 camera will provide a good balance of scan quality and ease of use. We support the use of stitched 360 panoramic video (equirectangular), or unstitched ( .insv or mp4) files from Insta360, Ricoh Theta, and Kandao cameras. Supported 360 cameras include the Insta360 OneRS, X2, X4, X5, Ricoh Theta X or Z1, and Kandao Qoocam 3 ultra.

For higher quality results, the cameras we recommend for recording video are the Z Cam E2-M4 and E2. They can be used with the Astrhori or Meike 6.5mm f/2 fisheye lens (MFT mount). Pre-assembled kits are available to rent or buy from Sensori.

Alternatively, you may use other cameras that support the capture of high bitrate video with a fisheye lens, but the results might be of a lower quality than with our recommended equipment.

360 Camera Settings

To get the best results with Insta360 cameras, we recommend using the highest resolution video setting at 24/30 frames per second.

For Ricoh Theta X1 or Z, the maximum resolution video mode is the best choice, but you may also use a lower framerate timelapse mode to save data size.

For the Kandao Qoocam 3 Ultra, the 3 fps timelapse mode is the best choice.

Pre-stitched equirectangular video at 24/30 frames per second is also supported, but will generally result in lower accuracy than using supported unstitched data.

Z Cam camera settings

The following video recording settings should be used for the recommended z cameras. If you are using an alternative camera then try to match these settings as closely as possible.

First update to the latest firmware version (currently 1.0.4).

A settings file containing our recommended settings is available for the E2, E2-M4 and E2-S6G.

Alternatively, use the following manual settings. Note that changing some settings might reset others, so double check all settings after completion.

Monopod

For capturing larger open areas such as road works, or for providing better visibility in inaccessible areas such as ceiling voids, we recommend mounting the camera to a monopod using a pan-tilt head.

Extra lighting

Sensori capture requires good illumination to be able to generate high quality geometry. When working at night with no other lighting, or in dark environments such as ceiling voids, a bright wide beam LED light may be fitted to the camera.

Scanning targets

Sensori Capture uses a standard set of targets for defining scale and registering against a control network. They are available to order from us, but you may also print your own.

If you are using a supported 360 camera then the scanning targets are optional for defining scale, but are still recommended for improved accuracy.

Origin plate and scale plates are available to download here. These should be printed at the original print size of the file. The distance between the centres of the target patterns is exactly 200mm and must be printed accurately. We recommend printing these on aluminium composite to reduce the risk of movement during outdoor captures.

Control point markers for use with survey points can be downloaded here. We recommend printing these on 3mm foam. Our standard size for these is 12cm across, but they may be used at any print size. The centre can be cut out as shown below.
