TDA2EG-17: (Vision_sdk 0307) 在我的chain上移植Use case 车道偏移演算法时，Vpe link 有Out Drop FPS状况 (急)

David ks

Part Number: TDA2EG-17

Dear TI 专家,

这是原本的chain (我有两颗镜头以及一个Panel):

Iss Capture -> Select_1 (后镜头) -> Framecopy(镜像) -> Merge_1 -> Select_2 ->VPE ->Display

-> Select_1 (前镜头) -> (Nothing) -> Merge_1

透过此chain可以看到前后镜头切换的效果且没有问题 (切到后镜头显示镜像，切到前镜头正常显示)

但是在将usecase : vip_single_cam_lane_detection 移植在前镜头的link上时却无法正常显示

==============================

如图，以下是修改移植后的chain =>红色框起部分 (备注: 我们板子上没有EVE Core , 所以拿掉了Alg_ImagePreProcess)

情况是我目前只有一个Panel所以靠Select_2来切换前后镜头

前镜头想要达到可以做车道偏移警示的演算法

后镜头只想做到Framecopy(镜像)

目前可以透过某些方式达到前后镜头的切换

在切换时后镜头显示没有问题

但切到前镜头画面却出不来

===============================

所以我印出link的状态

发现前镜头那路的Vpe的link 在一开始的时候就有 Out Drop FPS 的现象

不太明白VPE Link受到什么影响

想请问这如何改善这个问题呢?

请问我的link这样做有任何错误吗?或影响延迟的地方吗?

是否有哪个link会影响造成这个结果呢? 可能可以做哪些修改呢?

再麻烦各位专家了谢谢!

Best Regards,

David

Dear TI 专家,

(更新)

原本怀疑是演算法造成的延迟等状况

所以我做了一个测试

我将Alg_ImgPyramid,Alg_LaneDetect以及Alg_ObjectDraw link移除

前镜头的chain留下Vpe_1,Dup,Merge,Sync结果状况与现在相同

chains : Iss_capture -> select_1(前镜头) -> Vpe_1 -> dup ->Merge_1 -> Sync -> Merge_2 -> select_2 ->Vpe_2 -> display

-> select_1(后镜头) -> framecopy -> Merge_2 ->

Dear TI 专家,

(更新)

接下来我又拿掉了Vpe_1链接结果还是一样，看起来链接塞住了

chains : Iss_capture -> select_1(前镜头) -> dup ->Merge_1 -> Sync -> Merge_2 -> select_2 ->Vpe_2 -> display

-> select_1(后镜头) -> framecopy -> Merge_2 ->

Dear Cherry,

(更新)

目前link无法正常执行的原因找到了，是初始化值错误的关系

看起来整个chain已经打通了

但是另一个问题产生

如下图目前是我完整的chain

后镜头(framecopy 那边的Link)呈现出来的画面是正常的

但是前镜头(lanedetect 那边的Link)画面很奇怪如下图

我在猜测是否更VPE link设定有相关呢?

原因如下先前我有一个案例

我将VPE放在framecopy前面结果导致画面呈现奇怪的状态

但放在framecopy后又变正常

然后此次在lanedetect前镜头的chain共会经历两个VPE

第一个VPE是用来转格式SYSTEM_DF_YUV420SP_UV 用于 pyramid后的演算法

第二个VPE是用来做两颗镜头的裁切功能

这有关连吗?或是可能什么样的问题造成的呢?

Best Regards,

David
