Any ideas why these two error happen?

You're getting those errors because of the missing array operator. The operator $and requires an array, which should be represented as bson.A.

And how to fix it?

Please see the following pipeline:

Go mongodb driver ignores pipeline in aggregation

Asked 2019-Nov-12 at 00:12

Based on the example found on https://github.com/simagix/mongo-go-examples/blob/master/examples/aggregate_array_test.go I created the code below that runs a pipeline on a collection:

I don't know what I am missing but shouldn't I get the grouped results?

There are few things to point out here. The code example uses github.com/simagix/keyhole/mdb module for MongoPipeline. This function is supposed to take your string formatted MongoDB pipeline $group and converts into bson. This is a format that mongo-go-driver uses to send to MongoDB server.

Unfortunately the MongoPipeline function does not return any error that your code could catch, but the function is using encoding/json module to convert the pipeline into bson, and there are errors. The JSON parse errors that you're getting are:

invalid character '$' looking for beginning of object key string => Because keys need to be wrapped with "
invalid character '}' looking for beginning of object key string => Because there are extra comma(s) after }.

Due to these errors the MongoPipeline returns empty array [], which means undefined Aggregation Pipeline, and will return all documents in the collection.

The correct pipeline JSON string is (you can use jsonlint.com to validate)

QUESTION

How to set a point on an object via point-cloud/depth perception?

Asked 2017-Dec-22 at 22:23

Problem: My app cannot set a point on/near a point of the latest point-cloud data (on an object) through the click of a button.

Click this link to see the android app I have developed so far; I developed my app from the tango point-to-point measurement sample app

This app's features...

Shows camera data via the surfaceView.
The top-right red button closes the app.
Pressing the middle-right green button is supposed to set a point (of a point-cloud) on an object.
The top-left drop-down box allows you to change units of length.
The middle target is where the point is set after the green button is pressed.

As a head-start clue, my error originates from the getDepthAtCenter method (at the bottom of the second method below), since "No Depth Point." is posted on Android Studio's LogCat whilst the app is running.

Here is the setPoint method (upon clicking the green button)....

AreaDescription.SaveCurrent() freezes Unity's Update loop despite new thread

Asked 2017-Aug-23 at 15:03

I'm developing an app with Unity and Google Tango, and part of my code is saving an Area Description File (ADF) in a separate thread (so that my UI remains responsive):

ANSWER

Answered 2017-Aug-23 at 14:54

Under the hood, SaveCurrent() uses a System.Xml.Serialization.XmlSerializer which is, according to msdn, threadsafe.

But they initialize it with a StreamWriter where non-static members are not threadsafe.

But there is TextWriter.Synchronized which can help you.

Still not obvious why a separate thread would cause Unity to freeze. We have to assume that Unity waits for the thread to finish/not block anymore.

You can try to not extend Monobehaviour, see if Unity stops waiting then.

If that does not help, you need to read about volatile, and maybe check this relevant answers.unity3d thread

QUESTION

Getting pose data for OpenGL Coordinate System using Google Tango with Unity

Asked 2017-Jul-31 at 07:15

I am using Unity with Tango and I am having problems getting pose data. Unity application with Tango Unity SDK is built for Android device, device gets pose data and it sends it to the computer where additional processing is done using OpenGL. My question is, in which coordinate system is pose data returned since I can't define engine like with C API? Unity handles geting pose data like this, and nothing additional could be sent:

...

ANSWER

Answered 2017-Jul-31 at 07:15

I realized that I could expose function TangoSupport_getPoseAtTime in TangoSupport and add enums EngineType and RotationType (values are matched with C API).

So, I added this in TangoSupport.cs under TangoSupportAPI:

Tango Unity examples crashing when built with Unity 2017.1

Asked 2017-Jul-19 at 17:24

I just installed Unity 2017.1.0f3 and tried to compile the examples but all of them crash at start on my Lenovo Phab 2 Pro (Tango version 1.55).

I loaded the project tango-examples-unity\UnityExamples in Unity without modifying it and Unity converts it to the Unity 2017.1.0f3 version. The building seems to run fine but on the phone the resulting app crashes at start.

Everything worked fine for me on Unity 5.6. Maybe the Tango SDK is simply not supported yet by Unity 2017.1 but I could not find any information on that.

Here are the console output on Unity after building the app and the logs of the Tango when I launch the app and it crashes.

Answered 2017-Jul-19 at 17:24

After testing it has been confirmed that Unity 2017.1 is currently not supported by the Tango SDK, we only support Unity 5.6 at this time.
