Integrating AXIS Q6000-E

The innovative AXIS Q6000-E network camera is constructed to be used together with an AXIS Q60-E PTZ camera. The four camera heads in AXIS Q6000-E provide a 360° overview and the PTZ camera offers high detail optical zoom.

AXIS Q6000-E is to be mounted on top of the AXIS Q60-E PTZ camera. When mounted correctly, a connection between the two cameras is established automatically. After software setup and calibration, an operator can control the PTZ camera’s pan, tilt and zoom movements by clicking in the image from AXIS Q6000-E. When clicking in the image and when using area zoom, the PTZ camera will be redirected to and zoom in on the object the operator clicked on.

The images above show how AXIS Q6000-E is mounted on top of the PTZ camera. The arrows in the image to the right indicate the four camera heads. For mounting instructions, see AXIS Q6000-E installation guide.

Configuring AXIS Q6000-E

To configure AXIS Q6000-E, use the following APIs:

• VAPIX® Remote camera control API

  Manage the connection to a remote camera. See Remote camera control API.

• VAPIX® Remote PT coordinate calibration API

  Calibrate the pan and tilt coordinates in a remote camera. See Remote PT Coordinate Calibration API.

In the API descriptions, AXIS Q6000-E is referred to as the local camera and the PTZ camera is referred to as the remote camera.

Using AXIS Q6000-E

The connection between AXIS Q6000-E and the PTZ camera is established automatically when the cameras are mounted. After calibration, the PTZ camera can be controlled from AXIS Q6000-E. When using area zoom or clicking in the image from AXIS Q6000-E, the remote PTZ camera will be redirected to and zoom in on the object the operator clicked on.

A client may, for example, display the four images from AXIS Q6000-E in a quad view and, at the same time, display the image from the PTZ camera in a separate window.

When sending the following area zoom command to AXIS Q6000-E, the PTZ camera will be redirected and will zoom in on the selected area.

http://<Q6000-E address>/axis-cgi/com/ptz.cgi?camera=1&areazoom=0,0,300

It is also possible to use the center command (click-in-image) to control the PTZ camera:

http://<Q6000-E address>/axis-cgi/com/ptz.cgi?camera=1&center=20,50

For information about com/ptz.cgi, see PTZ control.

Remote PT Coordinate Calibration API

Description

VAPIX® Remote PT coordinate calibration API is used to calibrate the pan and tilt (PT) coordinates in a remote Axis PTZ camera that is connected to the local Axis product. The local Axis product is typically AXIS Q6000-E, see Integrating AXIS Q6000-E.

Calibration translates the coordinate spaces between the two cameras and is required for the Axis product to be able to accurately control the remote camera’s PTZ movements. After calibration, an operator can control the remote PTZ camera from the local Axis product by clicking in the local camera’s image or by using area zoom. The remote PTZ camera will be redirected to and zoom in on the position the operator clicked on.

The Remote PT coordinate calibration API provides the following functionality:

• Start calibration.
• Stop (abort) calibration.
• Select calibration targets.
• Match calibration targets in local and remote camera.
• Save calibration data.

Identification

The Remote PT coordinate calibration API is supported if:

• Property: Properties.API.HTTP.Version=3
• Property: Properties.PTRemoteCalibration.PTRemoteCalibration=yes

Calibrate a remote PTZ camera

The following is an overview of the steps required to calibrate a remote PTZ camera using the API.

Step 1: Start calibration

Start calibration by sending the following request to the local Axis product. The request below starts calibration using camera head two.

Request:

http://<servername>/axis-cgi/ptremotecalibration/start.cgi?camera=2

For more information about the request, see Start calibration.

Step 2: Select first calibration target

Select the first calibration target. The calibration target is a point in the image from the camera specified in the start.cgi request. Select a point in the image that is easy to distinguish as the remote PTZ camera should be directed to the same point. The point should be specified as normalized x and y coordinates.

Request:

http://<servername>/axis-cgi/ptremotecalibration/selecttarget.cgi?x=0.75&y=0.25

For more information about the request, see Select calibration target.

Step 3: Position the remote PTZ camera

Position the remote PTZ camera to center on the same point as the camera in step 2.

For information about how to control a PTZ camera using VAPIX, see Pan/tilt/zoom API.

• Use com/ptz.cgi?center=<x>,<y> to center the camera at point <x>,<y>.
• Use com/ptz.cgi?query=position to retrieve the PTZ camera’s current position.

Step 4: Save the remote position

On the local Axis product, use the ontarget.cgi request to inform the local Axis product about the remote PTZ camera’s position. If the local Axis product keeps track of the remote PTZ camera’s position, the request can be sent without arguments.

Request:

http://<servername>/axis-cgi/ptremotecalibration/ontarget.cgi

If the local Axis product does not keep track of the remote PTZ camera’s position, the remote camera’s pan and tilt coordinates must be specified in the request:

Request:

http://<servername>/axis-cgi/ptremotecalibration/ontarget.cgi?pan=124.7&tilt=44.2

For more information about the request, see On calibration target.

Step 5: Select additional calibration targets.

Select the second calibration target:

Request:

http://<servername>/axis-cgi/ptremotecalibration/selecttarget.cgi?x=0.25&y=0.25

The response to the second, third, etc selecttarget.cgi request returns approximate PT coordinates for the remote PTZ camera.

Response:

HTTP/1.0 200 OK
Content-Type: text/xml

<?xml version="1.0" encoding="utf-8"?>
<PTRemoteCalibrationResponse SchemaVersion="1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.axis.com/vapix/http_cgi/PTRemoteCalibration1.xsd">
  <SelectTargetSuccess>
    <Pan>-145.6</Pan>
    <Tilt>-36.7</Tilt>
  </SelectTargetSuccess>
</PTRemoteCalibrationResponse>

The coordinates in the response can be used to help position the remote PTZ:

Request:

http://<remote_servername>/axis-cgi/com/ptz.cgi?pan=-145.6&tilt=-36.7

When the remote PTZ camera is centered on the calibration target, save the remote position:

Request:

http://<servername>/axis-cgi/ptremotecalibration/ontarget.cgi

Continue to select calibration targets. It is recommended to use at least 4 points.

Step 6: Save calibration

When enough calibration targets have been set, the calibration data must be saved. During saving, a coordinate transformation curve is created and the calibration process is finalized.

Request:

http://<servername>/axis-cgi/ptremotecalibration/save.cgi

The request returns an error if calibration is not possible, for example if too few points were selected or if one or more calibration points were too poorly matched between the local camera and the remote camera. If so, restart the calibration process using start.cgi and add calibration targets as above.

Step 7: Repeat

Repeat the calibration process for the remaining camera heads until all have been calibrated.

Start calibration

Use ptremotecalibration/start.cgi to start calibration.

Error codes: 10, 20, 40, 54

Select calibration target

Use ptremotecalibration/selecttarget.cgi to select a calibration target in the image from the local Axis product.

The calibration target should be specified as normalized x and y coordinates of a point in the image. Point (-1.0, -1.0) is the bottom left corner of the image, point (0.0, 0.0) is the center of the image and point (1.0, 1.0) is the upper right corner. Do not change the camera’s aspect ratio before calibration. The coordinates in the request are interpreted as normalized on an image with the same aspect ratio as the camera’s default resolution.

After sending a selecttarget.cgi request, position the remote PTZ camera to center on the same point and then send a ontarget.cgi request to the local Axis product. See Calibrate a remote PTZ camera.

If sending multiple selecttarget.cgi requests before an ontarget.cgi request, the coordinates in the last selecttarget.cgi request will be used for calibration.

The first selecttarget.cgi request returns a GeneralSuccess. Subsequent selecttarget.cgi requests return an approximation of a matching pan/tilt pair in the remote PTZ camera that can be used to make it easier to position the remote PTZ camera.

Save calibration

Use ptremotecalibration/save.cgi to save the calibration data. The save request finalizes the coordinate translation and stops the calibration process.

Saving is the last step in the calibration process. See Calibrate a remote PTZ camera. The save request saves the calibration data from the selecttarget.cgi and ontarget.cgi requests in the ongoing calibration process. After saving, the calibration sequence is stopped. Use start.cgi to start a new process.
