Which Multi-Imager Cameras Do Panoramic Stitching?

Hi

Personal experience. Multi imager that don't stitch are useful. No doubt. T For a camera that calls itself "panoramic", stitching should be standard. It shouldn't be the exception.

 I believe we all have been in situation where the customer expected stitched images when buying "Panoramic" ... That disappointment however slight will result in lost sales at one point or another.

On that is there a list of Panoramic cameras that perform stitching? VMS that can do stitching? Those lists would be much welcome as the manufacturers are very obtuse about stitching...

#1 good question. We should have a list and we will use this to create one.

Immediately off the top of my head, I recall (from our tests): Pelco Optera 180° Camera Tested and Hikvision PanoVu Multi Imager Tested

Additionally, all Pelco Optera models, 270 degree and 360 degree as well, stitch and blend at the boundaries to present a single seamless panorama that you can immersively PTZ in.

Hi

To pounce a bit more on the issue: Smartphones perform "panorama" routinely on still images perhaps a bit more computation would be required for video. OTOH , in an IP multi-imager the sensors are in a fixed.  known (by the camera or VMS) position. Why is stitching so rare? How Panoramic is a camera if the views is spread over 3 , 4 screens...?

Right now it appears as though none of the VMS do the stitching internally that I am aware of.  That would be a logical spot for it to occur.  Stitching on the cameras may be limited by several items:

- Processing capabilities on the camera

- Cost of development for what was a niche product.  However, multi-imagers are becoming less of a niche.

- The potential for distortion and possible legal challenges that could arise from that.

- Most of the multi-heads on the market are independently repositionable which would eliminate stitching.  Exceptions that do not include stitching but are locked/limited in orientation include the Axis Q3709-PVE, Q3708-PVE, and Q6000-E.

Hi

I didn't think of the legal challenge, perhaps an issue .. perhaps not. It should be possible to record the sensors streams as well as the stitched view. 

Now concerning the processing power to do it. This is routinely performed by smartphones they don't even require a tripod... In the case of the IP camera the sensor are position-able but once this step performed they remind in the same position. Calibration may not be automatic but could be part of the setup. As for niche, the category is evolving and frankly is an answer  for situational awareness. Linkage of panoramic views to PTZ positioning and tracking is for some my customers a most needed feature. ...  ...There has been IMO a freeze in VMS capabilities.. They do about the same things a bit better but the promises of about 7 years ago are for the most part unfulfilled ...  Ai anyone? Facial Recognition ? Allowing us to stitch video images would be a plus. Processing power from GPU is available and inexpensive so

The Hanwha PNM-9030V and PNM-9020V perform stitching in the camera

The Axis P3807 as well as the Q37 series are 180 degree stitch-less panoramic cameras.

I have tested the Axis P3807 ($1349msrp)at our headquarters and it looked fantastic. The stitching is hardly noticeable, great WDR. I dont think the Axis Q series panoramics are much better for the extra cost, but I have not physically seen them working. 

 

The axis M3047,48,57,58 series are fish eye cams that also internally dewarp and send some panoramic streams. Works well in a low ceiling or small space

Dallmeier Panomera not sure if its the camera or the VMS that does the stitching 

Westpac Stadium in Wellington, New Zealand use this system

Hi

 

More research revealed that Dahua has  the PFW8601-A180 PANORAMA which performs in-camera stitching

I take this opportunity to ask the collective for the following: The Dahua PSS application touts that they can link click on a panoramic picture to a PTZ.. In other words you click a point on the panoramic picture and the PTZ will go that point. At a specified focal length I suppose. This is a requested features by a few customers. Can this be done by other VMS? Other camera combo? I know that Axis pairs some of its Panoramic cameras to  some Axis PTZ cameras . The Hikvision Panovu has some models with PTZ which perform this ... What VMS support support this features? Thanks in advance.

Pelco Optera 180, 270 and 360 degree models can be connected with Pelco Enhanced Class PTZ cameras like Spectra Enhanced, Esprit Enhanced and ExSite enhanced that are mounted nearby with Pelco Camera Link technology. You can manually point in Pelco VideoXpert VMS UI to an person or vehicle in Opteras panoramic view and the PTZ nearby will point and zoom in to it. You can also set it to automatically track objects. The latter function is particularly effective in applications where you don't expect people or vehicle traffic, but when something shows up, you want to track them closely - such as after hours when you have no/fewer  surveillance operators.
