내가 진짜 돈을 내고 한게 아니면 소득공제 안된대서 시들해졌지만

그럼에도 불구하고 일주일에 한번 클릭으로 몇백원 모아두고

내 돈 안쓰고 기분내는 기부다 보니 꾸준히 하게 되네

deepstream 6.0 부터 NHWC 네트워크 입력을 지원한다고 한다.

그런데 이 NHWC가 먼지 몰라서 헤매는 중...

그러니까.. 이전에는 NHWC는 지원하지 않았으니 NCHW만 지원했던건가?

Support for NHWC network input DS 6.0

 

nvinfer 모듈에서 NCHW가 언급되는 항목은 아래와 같은데

입력 레이어, 출력 레이어의 순서 그리고 uff 관련 입력 차원/순서에 대한 내용인데..

UFF 안쓰면 network-input-order와 segmentation-output-order만 보면 될 것 같긴하다.

network-input-order Order of the network input layer (ignored if input-tensor-meta enabled) Integer 0:NCHW 1:NHWC network-input-order=1 All
Both
segmentation-output-order Segmentation network output layer order Integer 0: NCHW 1: NHWC segmentation-output-order=1 Segmentation
Both
uff-input-dims DEPRECATED. Use infer-dims and uff-input-order instead.
Dimensions of the UFF model
channel; height; width; input-order All integers, ≥0 input-dims=3;224;224;0
Possible values for input-order are:
0: NCHW
1: NHWC
All
Both

 

uff-input-order UFF input layer order Integer 0: NCHW 1: NHWC 2: NC uff-input-order=1 All
Both

conv 연산시 nhwc가 nchw에 비해서 빠르다고 하는데 데이터 순서에 따른 인접성 때문에 그런가?

[링크 : https://moon-walker.medium.com/train-faster-텐서플로우-성능-최적화-기법-d67d3faee959]

 

약어는 아래와 같다고.

N: number of images in the batch
H: height of the image
W: width of the image
C: number of channels of the image (ex: 3 for RGB, 1 for grayscale...)

[링크 : https://stackoverflow.com/questions/37689423/convert-between-nhwc-and-nchw-in-tensorflow]

[링크 : https://code-examples.net/ko/q/23f184f]

 

일단.. deepstream 에서 받아들이는 텐서는 3x320x320 인데

젯슨 나노 하나 전체를 찍을 만큼의 배율과 촛점 거리는 안되는 듯..

[링크 : https://www.flirkorea.com/products/ets320]

 

사용자 설명서를 보니 FOV 고정, 촛점거리 7cm 로 고정 -_ㅠ

영상은 초당 9프레임

 

하지만 UVC 상에서는 15프레임으로 프레임이 변경되는 듯.

어찌된게...  AI  컨퍼런스, 전시회 보다 볼게 더 없냐 -_-

전시공간은 킨텍스라 넓은데 공간을 다 채우지도 못하고 넓직 넓직하게 띄워놓고..

 

아무튼 딱히 이렇다할 눈에 띄는 솔루션도 없고

업체들도 어쩔수 없이 그냥 구색 맞추기로 대충 나온 느낌.

primary / secondary가 먼가 했더니..

한번 분석한걸 tracker를 거쳐 한번 더 분류하는 식으로 구성이 가능하도록 되어 있었기에 그런식으로 표현한 듯.

 

nvtracker는 openCV 기반이라 쓸 일은 없을 것 같고..

nvmultistreamtiler 가 nvstreammux 을 통해 받은 영상을 tile 구조로 mux 해서 출력해주고

nvosd가 nvinfer의 결과값을 받아 이름과 박스를 쳐주는 듯.
