SpheronVR SceneCam -Conclusion / Reflection
(Based upon the 2 case common studies and extensive familiarization period / tests)
Overall, I would consider the Spheron SceneCam as (as tested):
- A Premium solution
- Generates extremely faithful output
- Highly Flexible given alternate lens capability
- Has reliable and durable battery operation – 8 hours plus per set (at standard ambient temp). An impressive 2 hours when operated in -22 Deg C / -7.6 F.
- Extremely stable software solution for both camera control and post-processing of data. No issues experienced during captures.
- Can be susceptible to luminance changes in scene / capture area – which may cause banding in image.
- Offers great versatility at capture and post processing through the proprietary software.
- A Professional solution, where perfect results are the expectation.
The system as tested was (one can consider) the flagship product for Spheron VR AG, as there is an alternative, cheaper solution on offer, via the recently released Spheron-LITE. As Spheron does not disclose system costs publically, I shall respect that decision. Pricing available from Spheron directly.
The system also featured a locked focus ring of the standard 16mm NIKON NIKKOR lens (fixed by Spheron), so I was unable to achieve manual focusing (which would have allowed ‘precision focusing’ using Spheron software to designate areas of focus) which in the case of ultra close cockpit interiors was unfortunate – even so, results were impressive.
Image capture was excellent however, with minimal (if any) discernible distortion and very faithful geometric representation – as it is not a ‘stitched image.’
Very little if any chromatic aberration, coupled with excellent / faithful color representation.
In situations where one relies upon ambient light only, where lighting conditions change, these can manifest themselves as ‘bands’ in the image. Ultimately, the end application of the data will determine if this is a problem or not. If so, a rescan may be required.
If ambient light is too low, the adoption of the Spheron ScanLight attachment will resolve this, offering 58MP resolution scans at a 7 minute scan time constant. The ScanLight is an elegant solution, as it provides balanced light output, without cluttering the scene with additional floodlights or cables etc. Being affixed to the camera itself, you won’t even see the system in any of your captures.
Flexibility at capture is excellent also, as there are a plethora of solutions / shooting permutations available if one chooses the more sophisticated camera control software. Post-production is also afforded a multitude of options and export capabilities.
It should be noted that SpheronVR also go beyond just ‘image’ capture, as their excellent SceneWorks / SceneCenter solution makes a fantastic job of contextualizing both the images and any other associated data (laser, forensic, VAM, document, video, audio or stills) within a collaborative, secure workspace. But that’s another story 😉
