TDA2: Tda2x VisionSDK

Hello

Thanks for picking TI TDA2x and vision SDK for your DMS program.

With respect to OpenCV, please note that you will have to use the pre-built library of openCV along with VSDK. It will not be possible to support you on how to build, adding new libs etc. to it, because the openCV support infrastructure is deprecated.
I would suggest you to use the native "Links and Chain" architecture of Vision SDK rather than OpenCV to build your DMS application.


Kumar,

Kindly answer the queries related to dlib, caffe and rppg libs etc.?


Regards, Shiju

Dear officer,

Any updated on dlib, caffe and rppg? Any pre-build libs? Is there any restriction on bios or linux?

Thanks and best regards

Dear Kumar,

So "caffe is not linking directly" but its funcationality can be achieved by TIDL and TIDL is part of standard SDK release,e .g . PROCESSOR_SDK_VISION_03_04_00_00? Am I correct?

Dear Kumar,

Firstly we are trying to use the OpenCV, based on the report from <install dir>\ti_components\open_compute\opencv\opencv-3.1.0\docs , it shows some test cases are failure or not supported by bios, e.g. objdetect is not showing in bios, So Can i say Linux openCV provide better support/features than bios? And Can I direct build Linux openCV in windows environment by gmake? e.g. set the below in windows environment:

MAKECONFIG=tda2xx_evm_linux_opencx

I got complilation error when doing this.

So To build linux opencv app, I must build it in native Linux host? i.e. I need to do :
MAKECONFIG=tda2xx_evm_linux_opencx
In native Linux host only?

Thanks and best regards
He Wei

Dear Shiju,
Ok. I got question regarding on Linux build on PROCESSOR_SDK_VISION_03_04_00_00 by following VisionSDK_Linux_UserGuide.pdf:

1. Based on default configuration: MAKECONFIG=tda2xx_evm_linux_all

The build is successfully and the corresponding 2 partition is generated in SD Card:
a. boot:
MLO u-boot.img uenv.txt
b. rootfs:
bin etc lib mnt opt sbin usr
boot home lost+found opencl_fs_patches proc sys var
dev include media opencl_fs_patches.tar.gz run tmp

But when running from tdax2 board, it shows error:
Booting from eMMC ...
Wrong Image Format for bootm command
ERROR: can't get kernel image!
=>

Any advise on the error?


Take note that: I am using "make" to build the sdk in my Linux host instead of "gmake" as indicated in user guild, is this typo in Linux user guild? Or I should install gmake in Linux?

2. Then If I change the build configure as: MAKECONFIG=tda2xx_evm_linux_opencx,
Then I got build error:
/home/hewei/PROCESSOR_SDK_VISION_03_04_00_00/vision_sdk/../ti_components/os_tools/linux/targetfs/usr/share/ti/opencl/bin/x86/clocl: Command not found
Makefile:5: recipe for target 'copy.dsp_h' failed
make[7]: *** [copy.dsp_h] Error 127

Do I miss some things?

Thanks and best regards

Dear Shiju

Tks and few questions:

1. In \vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_UserGuide_opencx.pdf, it means to build the openCV source code, (section 1.4), I thought the OpenCV is pre-build in the SDK already and no need to re-build from the source code, am I right?
2. Must to rebuild the cmem too?
3. In my build case, I set:
MAKECONFIG=tda2xx_evm_linux_opencx,

The error is that it can find the clocl cmd in the below path: home/hewei/PROCESSOR_SDK_VISION_03_04_00_00/vision_sdk/../ti_components/os_tools/linux/targetfs/usr/share/ti/opencl/bin/x86/clocl: Command not found
Should I install the "clocl" cmd in that path and build?

Thanks and best regards

Typo:

The error is that it can not find the clocl cmd in the below path: home/hewei/PROCESSOR_SDK_VISION_03_04_00_00/vision_sdk/../ti_components/os_tools/linux/targetfs/usr/share/ti/opencl/bin/x86/clocl: Command not found
Should I install the "clocl" cmd in that path and build?

Please make sure you untar the open CL tarball into the file system.

Follow the steps in VisionSDK_Linux_UserGuide.pdf

2.4.2.2.4 Opencl supported package

Dear Shiju,

We had done this 2.4.2.2.4 already. and Can I confirm if the "object detection" is supported by this Linux openCV build? (We understood the object detection is not supported in BIOS openCV, this is the reason we want to build in this Linux build.)

Thanks and best regards
He Wei

Hello
object detection is not supported in OpenCV build, neither Bios nor Linux build

regards, Shiju

Dear Shiju,

So we won't get any additional openCV features support if switching from TI Bios build to TI Linux build, am I right?
Based on the test report from ti_components\open_compute\opencv\opencv-3.1.0\docs: there is one sheet "objdetect" in vayu_arm_linux_opencv_test_report.xlsx but this sheet is not shown in vayu_arm_bios_opencv_test_report.xlsx. Actually this is the reason we thought objection detection is supported in Linux build . So this is not the case?

Thanks and best regards
He Wei

Dear Shiju,

More clear now. Normally OD is a standard feature/package in OpenCV, any reason why it is not in the TI SDK OpenCV pre-build? Any constraint? (I am asking to check if it is worth for us to do the cross-compile to add OD in). Or there is already a alternate away as you mentioned to preform the OD already hence there is no need for OpenCV OD?

Further, what is the exact list of supported OpenCV features in ths VSDK ? e.g. Feature2D, imgproc, etc. - by knowing this, we could know what we can use and we can't use for the TI VSDK prebuild OpenCV.

Thanks and best regards
He Wei

Dear Shiju,

In addition, I notice in:
\vision_sdk\apps\src\rtos\usecases\vip_single_cam_object_detection2

It is based on TDA3xx, actually we are workin gon TDA2xx board, hence this UC will not be usefully for us? Any OD UC is based on TDA2xx?

Thanks and best regards
He Wei

Hi He Wei
No, we do not support any of this features (OD, Feature2D, imgproc, etc.) in recompiled open CV lib.
Very basic kernel/functions like cannyedge & dilation are only supported.
Please use pre-built library of openCV. It will not be possible to support you to add new libs and on how to build it etc. because the openCV support infrastructure with VSDK is deprecated.

regards, Shiju

Hello He Wei
\vision_sdk\apps\src\rtos\usecases\vip_single_cam_object_detection2
is supported on both TDA2x and TDA3x

regards, Shiju

Dear Shiju

Noticed and Can I ask what is detail kernel/functions for TI VSDK pre-build OpenCV supported? (The reason I am asking is because we have some algo./function developed in Windows based on OpenCV, now we need to re-design/re-implement rather than direct porting as thought before, but we need to know what is exactly the TI SDK pre-build OpenCV can support..)


Thanks and best regards
He Wei

Dear Shiju,

I noticed that in PROCESSOR_SDK_VISION_03_04_00_00\ti_components\open_compute\opencv\opencv-3.1.0, it contains both openCV ibs_bios and libs_linux, So does it means TI has done the OpenCV cross-compile for both ARM bios and Linux? If this is the case, Can I just include these lib (+header files) into SDK then I can have entire set of OpenCV?

Thanks and best regards
He Wei
