Stitching

Description

The Stitching API documentation introduces you to the steps that lets you set the blending amount and parallax compensation distance in order to reach optimized alignment in a panoramic video stream. By using this API you will also be able to align the sensor images in a panoramic view in the event that one or several sensors have been moved from their original position.

Model

The API implements stitching.cgi as its communications interface and supports the following methods:

Method	Description
`getSupportedVersions`	Retrieves API versions supported by your device.
`getCapabilities`	Retrieves stitching capabilities available on your device.
`getBlendingAmount`	Retrieves the current blending amount.
`setBlendingAmount`	Sets the blending amount.
`getParallaxCompensationDistance`	Retrieves the current distance to an object.
`setParallaxCompensationDistance`	Sets the distance to an object (in meters).
`rotateAngle`	Rotates a sensor ID.
`restore`	Restores a sensor ID to the factory default setting, i.e. removes all changes made with: `setBlendingAmount` `setParallaxCompensationDistance` `rotateAngle`

setBlendingAmount

This method is used when you want to set a new blending amount value. Changing this value is useful when there are differences in the white balance between sensors.

It is generally a good idea to set the blending amount to 0 when there is only one object at the same distance as the parallax compensation distance around the seams. This will add a sharp transition between seams, however, in cases where there are many different objects at different distances around the seams it is usually better to increase the blending amount. Doing this will blur our any skewered alignments that might occur around the seams.

rotateAngle

This method is used when you want to align the sensor images in the panoramic view to improve the stitching effect.

Each sensor can rotate on the “pan”, “tilt” and “roll” axis. The hard limits of the angles can’t exceed -180 to +180 degrees, but there are lower soft limits that are product and sensor dependent. AXIS Q3819–PVE for example, has a soft limit of ± 1.4 degrees when using pan. Exceeding these limits can cause unknown behavior in the image.
