Surround view Application support for iMX6QP(Linux)

balasubramaniyam — Tue, 11 Dec 2018 10:07:18 GMT

Hi,

I am using Linux imx-4.9.11 release and Yocto Morty build for iMX6QP.

How to add the support for "3D Surround view application" package in yocto for iMX6QP

I tried to build the surround view application in the iMX6QP device, but I got the segmentation fault while executing surround-view-3D_1.1_beta binaries.

NOTE:

3D Surrounded view application package and documents used from the below link.
Surround View Application|NXP

Hoping for a better guidance.

Regards,

Bala

Are you follow the build command in SVARM.pdf to build the BSP? The verified images in the document mentioned is L4.1.15. Please try to use L4.1.15 BSP.

I tried both L4.1.15 BSP and L4.9.11 BSP package. Both got the same segmentation fault.

Followed section "3. Building applications from sources" from SVARM.pdf to build the image.

After application built without any error, executing SV3D capturing binariesfrom the following path /Tools/CamCapture/capturing and I got the segmented failed error while running the SV3D capturing bianries.

Note:

I added some of the required packages in rootfs to built the SV3D application

I can run the demo correctly with INPUT=image.

But when I using the dumping image from my car, it can find the Contours correctly, but with a wrong grid output...

I am sure my template is right.

Could you please give some advice?

and I find if increase start_angle， it will segment fault...

<grid>

<start_angle>4</start_angle>

<nop_z>30</nop_z>

<step_x>0.2</step_x>

</grid>
