Viewer Sequence

Viewer sequences are defined as arrays in JSON format.

Specifying viewer sequences is optional. You may leave out specifying this in your configuration file. However, if you're specifying them, you can define one or more viewer sequence. The name of each sequence must follow the format: viewer_sequence_number where number must be 1 for the first viewer sequence you define, and each subsequent sequence you specify, number is incremented by one. For example:

...
    "viewer_sequence_1": [
        {
            "instance": 1, 
            "visible": false
        },
        {
            "instance": 4, 
            "visible": false
        },
        {
            "instance": 2, 
            "view": "ADAS_VIEW_ISOMETRIC",
            "zoom_factor": 2
        },
        {
            "instance": 2, 
            "visible": true
        },
        {
            "instance": 3, 
            "visible": true,
            "sleep_ms": 10000
        },
        {
            "instance": 2, 
            "view": "ADAS_VIEW_ISOMETRIC",
            "zoom_factor": 4,
            "sleep_ms": 6000
        },
        {
            "instance": 2, 
            "view": "ADAS_VIEW_BIRDSEYE",
            "zoom_factor": 2,
            "sleep_ms": 6000
        },
        {
            "instance": 2, 
            "view": "ADAS_VIEW_BIRDSEYE",
            "zoom_factor": 1,
            "sleep_ms": 6000
        },
        {
            "instance": 2, 
            "visible": false
        },
        {
            "instance": 3, 
            "visible": false
        },
        {
            "instance": 1, 
            "view": "ADAS_VIEW_FORWARD",
            "zoom_factor": 1
        },
        {
            "instance": 1, 
            "visible": true
        },
        {
            "instance": 4, 
            "visible": true,
            "sleep_ms": 15000
        },
        {
            "instance": 1, 
            "view": "ADAS_VIEW_RADAR",
            "zoom_factor": 1,
            "sleep_ms": 6000
        },
        {
            "instance": 1, 
            "view": "ADAS_VIEW_NAVIGATION",
            "zoom_factor": 2,
            "sleep_ms": 6000
        }
    ],
...

Attributes:

There are the properties that you can use to configure each element of the array for a viewer sequence.

instance

(Required) The instance of a viewer. The value is the index of the viewer that's configured in the viewer array in your configuration file. The index is in range [1..n] where n is the total number of viewers in your viewer array. For example, if in your viewer array, you have these entries:

...
    "viewer": [
        {
            "type": "ADAS_VIEWER_CAMERA",
            ...
        },
        {
            "type": "ADAS_VIEWER_POINT_CLOUD",
            ...
        },
        {
            "type": "ADAS_VIEWER_OVERLAY",
            ...
        },
        {
            "type": "ADAS_VIEWER_OVERLAY",
            ...
    ],
...

then you can specify 1 (the viewer whose instance is ADAS_VIEWER_CAMERA) as the instance property. For example:

...
    "viewer_sequence_1": [
        {
            "instance": 1, 
            ...
        },
...

sleep_ms

(Optional) The amount of time (in milliseconds) to wait before applying the next entry in the viewer sequence. For example:

...
        {
            "instance": 3, 
            "sleep_ms": 10000
        },
...

view

(Optional)

Note: You must specify one of view or visible, but not both, properties in an element of the viewer sequence.

The new view that the viewer selects. Valid entries for this property are:

ADAS_VIEW_BIRDSEYE
ADAS_VIEW_MOSAIC_2X2
ADAS_VIEW_ISOMETRIC
ADAS_VIEW_FORWARD
ADAS_VIEW_BACKWARD
ADAS_VIEW_DRIVER
ADAS_VIEW_RADAR
ADAS_VIEW_NAVIGATION

See adas_view_t.

visible

(Optional)

Note: You must specify one of view or visible, but not both, properties in an element of the viewer sequence.

An indicator of whether the viewer is visible (true) or invisible (false). For example:

...
            "visible": true,
...

zoom_factor

(Optional) The initial zoom factor to use if view was specified. If zoom_factor is not specified, the default is 1. For example:

...
            "zoom_factor": 1,
...
