Radar image

Description

Use the radar image API to:

configure properties of virtual video streams generated to show information from a radar sensor.
setting up a reference map for the video stream and align the radar data.

The virtual video stream consist of the following elements:

Background: Either a solid color or a reference map added by the user.
Grid: Marks the radar field of view and give the user a way to determine the distance to the tracked object.
Echoes: Raw responses from the radar sensor.
Radar tracks: Echoes grouped together from the same object, filtered to remove uninteresting ones.
Radar track trails: Tracks history displayed in the image.

Supported CGIs:

`uploadradarimage.cgi`	Upload an image and set it as a reference map in the video stream.
`replaceradarimage.cgi`	Replace an already calibrated reference map in the video stream.

Overview

Model

The API consists of three CGI calls which should be called using the HTTP POST method. The calls uploadradarimage.cgi and replaceradarimage.cgi use multipart/form-data for sending binaries while radarimage.cgi accept JSON formatted data. All three return JSON formatted data. This all give the user the possibility to:

Upload an image and set it as a reference map.
Replace a reference map with a new image.
Calibrate the radar so it aligns the grid and radar tracks to a reference map.
Fetch image parameters like color scheme, opaque level, echo visualization level, filename and trail lifetime.
Set how long a trail should be displayed.
Set color scheme.
Set grid opaque.
Set level of echo visualization.
Request a list with the supported API versions.

Identification

Property: Properties.Radar.Radar=yes
Property: Properties.AddOnFramework.AddOnFramework=yes
Property: Properties.AddOnFramework.Version=1.0 or higher
Firmware: 7.10 and later
Product category: Axis Cameras with application support.

Application identification

The getInfo method in axis-cgi/packagemanager.cgi lists axis-rmd as active.
or
The property Properties.Radar.Radar equals "yes".
