Presets for D435

MBerg10 — Tue, 23 Oct 2018 16:36:20 GMT

When I try to apply a preset by using the rs2_set_option(..., RS2_OPTION_VISUAL_PRESET, 1, ...) it doesnt work. There is no error but also there is no effect at all.

However, if I load one of your json-presets (from https://github.com/IntelRealSense/librealsense/wiki/D400-Series-Visual-Presets) by using rs2_load_json() everything works fine.

Are there any special steps to consider when doing it the rs2_set_option way??

What settings are you trying to change with the json please? Earlier in the year (May 2018), it was not possible to set FPS and resolution with a json because the pipeline sets them instead. Intel were thinking about looking into how to change this, but I don't know if they have implemented that yet.

In the link below is a statement about it from Sergey 'Dorodnic' Dorodnicov, the RealSense SDK Manager.

Hello matspetter,

Thank you for your interest in the Intel RealSense D435 camera.

On GitHub issue https://github.com/IntelRealSense/librealsense/issues/1217 Using advanced mode presets via C API, dorodnic have posted a code that you can use as a start-up for your project. It uses the rs2_set_option function.

Best regards,

Eliza

No we are not trying to these two parameters. We just try to set the parameters relevant to HighAccuracy etc.

Yes I have looked into that example and we are (more or less) doing the same thing without any luck.

But isn't it strange that I can set presets with your json-files but not with set_option ?

The HighAccuracy, Default, Hand etc presets, they are not possible to over-write or? I mean if we by mistake could have overwritten them?

Are there any preconditions that are different when setting presets via json compared to set_option ?

Hello matspetter,

Is it possible to provide us the code that you are using in order to test it?

Thank you in advance,

Eliza

Hi. Our code typically looks like this:

context = rs2_create_context(API_VERSION, error)

deviceList = rs2_query_devices(context, error)

device = rs2_create_device(deviceList, 0, error)

list = rs2_query_sensors(device, error)

n = rs2_get_sensors_count(list, error)

for (i=0 ; i

sensor = rs2_create_sensor(list, i, error)

if (rs2_is_sensor_extendable_to(sensor, RS2_EXTENSION_DEPTH_SENSOR, error)) {

depthSensor = sensor

}

rs2_delete_sensor_list(list)

serial = rs2_get_device_info(device, RS2_CAMERA_INFO_SERIAL_NUMBER, error)

pipelineD = rs2_create_pipeline(context, error)

configD = rs2_create_config(error)

rs2_config_enable_device(configD, serial, error)

rs2_set_option(depthSensor, RS2_OPTION_LASER_POWER, 360.0)

if (setPresetViaOption) {

//========= this does not =====================

preset = 3.0 // HighAccuracy

rs2_set_option(depthSensor, RS2_OPTION_VISUAL_PRESET, preset, error)

//=============================================

} else {

//========= this WORKS ========================

rs2_load_json(device, jsonBytes, jsonBytes.size, error)

//=============================================

}

rs2_config_enable_stream(configD, RS2_STREAM_DEPTH, 0, width, height, RS2_FORMAT_Z16, fps, error)

pipelineProfileD = rs2_pipeline_start_with_config(pipelineD, configD, error)

rs2_set_option(depthSensor, RS2_OPTION_ENABLE_AUTO_EXPOSURE, 1.0)

after that we start reading frames. Both when we load the preset via set_option and via json it works to load frames. The difference is that when doing it via set_option it does not have any effect on the frames.

After each call above we also check that we didn't get any error in the error-variable.

Hello matspetter,

Thank you!

Could you please use: rs2_set_option((const rs2_options*)depthSensor, RS2_OPTION_VISUAL_PRESET, preset, error); instead of rs2_set_option(depthSensor, RS2_OPTION_VISUAL_PRESET, preset, error)?

Looking for ward to your reply!
