Can not create a database

MMich52 — Thu, 22 Dec 2016 10:46:39 GMT

Hello,

I use a RealSense R200 und SDK 2016 R2. I want create a database for recognition. By compile have a error -> EntryPointNotFoundException

Method: recognitionConfig.CreateStorage(databaseName, out recognitionDesc); ==> An exception of type "System.EntryPointNotFoundException" occurred in libpxcclr.cs.dll, but it was not processed in the user Code. Additional Information: The entry point "?" Was not found in the DLL "libpxccpp2c".

What can it be? Can you help me?

Generally works creating databases? Has someone created and used a database? Or is the dll simply damaged or not complete?

Hi Mischel,

Thank you for contacting us.

That's a weird issue, can you share your code to help you more? Or are you using any particular example?

We will be waiting for your reply.

Have a nice day.

Hello

databases creating does not work generally. In this example, https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdkhttps://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk

have I this error.

Hi Mischel,

I compiled the code without issues, I think you are getting that error, because you have to set the right path of libpxccpp2c. Use this guide as reference https://software.intel.com/en-us/articles/get-started-developing-intel-realsense-sdk-for-windows-10-desktop-apps, check the Adding References to the Intel® RealSense™ SDK Libraries.

Let me know if it works for you.

Hi,

there is no example with a database. I have a Problem with create database. if I comment CreateStorage(....) method, I can start und use the aplication --> recognition, save/load from file and etc. I have tried to create a database in this example https://software.intel.com/en-us/articles/intel-realsense-depth-camera-r200-code-sample-face-tracking https://software.intel.com/en-us/articles/intel-realsense-depth-camera-r200-code-sample-face-tracking

https://software.intel.com/en-us/articles/intel-realsense-depth-camera-r200-code-sample-face-tracking https://software.intel.com/en-us/articles/intel-realsense-depth-camera-r200-code-sample-face-trackinghttps://software.intel.com/en-us/articles/intel-realsense-depth-camera-r200-code-sample-face-tracking https://software.intel.com/en-us/articles/intel-realsense-depth-camera-r200-code-sample-face-tracking

What is created by CreateStorage(....)? Where is the database saved? Should the application have a special write rights for this folder?

Hi Mischel,

I compiled this example without issues and it creates a database. I didn't change the code and I don't that error that you are getting.

I was checking the SDK documentation: https://software.intel.com/sites/landingpage/realsense/camera-sdk/v1.1/documentation/html/index.html?doc_face_face_recognition_data.html, and it seems that it is a feature for the F200 and SR300 cameras, and you are using a R200.

Have a nice day.

Hi,

I have both cameras SR300 and R200. Can it be that program has not enough rights to create database(for example can not write a file)? I have admin rights on pc, but can not I can save and load from .bin file. Problem is only if I call the CreateStorage(....) method.

Best Regards

Hi Mischel,

I'm not understanding your issue at all, did you compile this examples without errors? https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk

Or is there that you are getting that error that you showed me?

Just to be clear, I compiled that example without issues and I'm not having problems with the function CreateStorage that is used in the example.

Have a nice day.

I have both cameras SR300 and R200 and have a Problem with create database too.

CreateStorage Method makes error message that is "Init:DLL don't find entry point, named '?' in 'libpxccpp2c'

Hi guys,

Can you tell me the steps that you are following? I need them to try to replicate the issue, because I didn't have errors when I compiled the code.

Have a nice day.

Hello,

I can't compile this example https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk

because I have the above error.

1. download sample code from https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk https://software.intel.com/en-us/articles/code-sample-facial-recognition-using-intel-realsense-sdk

2. unzip this and start a project with admin in VS 2015

3. compile and start a program for debug x64

4. error bei call CreateStorage(....); method

5. comment both lines with CreateStorage(..) and UseStorage(..) methods and then

6. compile -> ok

start programm -> ok

face recognition -> ok

but withouth database((((((((((

Hi guys,

I tried to replicate the issue following the steps that Mischel provided. And I didn't have issues, I think it is because I'm using the SDK R3 2016, so I recommend you to install it and try it with it again.

I hope you find this helpful.

Have a nice day.

Hello all,

I'm having the same issues.

This is not a compile time issue, but rather a runtime error. The lib "libpxccpp2c" is missing an entry point when calling CreateStorage(), etc. Your code will compile fine all the way through. It is when you execute the code that you get this error.

var recognitionConfig = moduleConfiguration.QueryRecognition();

recognitionConfig.Enable();

PXCMFaceConfiguration.RecognitionConfiguration.RecognitionStorageDesc description;

recognitionConfig.CreateStorage(FACE_IDENTIFICATION_DB, out description);

description.maxUsers = configuration.FaceDetection.Identification.MaxDetectedUsers;

The error happens when the method CreateStorage() is called.

Re: Can not create a database

idata — Sat, 07 Jan 2017 09:31:28 GMT

When using the official example, the method CreateStorage() is not called. This is why you get no errors there.

If you add the following lines to the face tracking C# example after line 192, the error will occur:

PXCMFaceConfiguration.RecognitionConfiguration.RecognitionStorageDesc storage;

qrecognition.CreateStorage("foo.db", out storage);

Hello,

Where is the difference? I can not use any database anyway.

Hi guys,

I have been able to create the database, first I commented the lines:

//recognitionConfig.CreateStorage(DatabaseName, out recognitionDesc);

//recognitionConfig.UseStorage(DatabaseName);

After I ran the code without issues and I the database is created in the path: Yourprojectfolder/FaceID/FaceID/bin/release or debug, the database is called database.bin

I am using the SDK 2016 R3.

Have a nice day.
