Compiler/OPT8241-CDK-EVM: How to calibration camera with VoxelSDK

Hi!

Can you answer the following questions, please?

What is the scene like? Can you share an image of the scene from a normal camera as well as an image of the amplitude image from Voxel Viewer?

OPT8241-CDK-EVM comes with pre-calibrated profiles and you don't need to calibrate it again. Which profile are you using?

Hi Suramya:

1.Maybe you understand what I mean wrong.Both depth and amplitude information is obtained from your sensor,It is not from a normal camera.

2.I am using RTS5825CameraNoCalibration.conf and RTS5825CameraNormal.conf. The list is the configuration information

RTS5825CameraNoCalibration.conf

[global]

id = 129

name = No Calibration

[defining_params]

unambiguous_range = 6

frame_rate = 25

sub_frame_cnt_max = 4

quad_cnt_max = 4

intg_time = 10

illum_volt = 1800

[params]

[calib]

fx = 230.492315023

fy = 231.489651268

cx = 151.531059295

cy = 117.57638468

k1 = -0.218646558104

k2 = 0.239127935299

k3 = -0.115480536339

p1 = 0.00141012577006

p2 = -0.00117499129377

RTS5825CameraNormal.conf

[global]

id = 128

name = Normal

[defining_params]

unambiguous_range = 6

frame_rate = 25

sub_frame_cnt_max = 4

quad_cnt_max = 4

intg_time = 10

illum_volt = 1800

[params]

[calib]

fx = 230.492315023

fy = 231.489651268

cx = 151.531059295

cy = 117.57638468

k1 = -0.218646558104

k2 = 0.239127935299

k3 = -0.115480536339

p1 = 0.00141012577006

p2 = -0.00117499129377

freq_corr = 1

freq_corr_at = 18

phase_corr_1 = -1205

Here is depth image and amplitude image.is it normal ? 
Why are there so many noises? How should I eliminate them?

Regards

Hi, 

What i meant was, to take a picture from a normal camera of the scene. However, it doesn't seem necessary, as the scene is just your hand. 

If you're using OPT8241-CDK-EVM, you should be using the MetrilusLongRange (HW) profile. I feel that is not the case here. 

The image doesn't look correct. Can you send the register settings? 

Suramya

Hello Suramya:

I am very sorry that I don't seem to know the file called "Metrilus LongRange(HW)".

I am using the latest voxelsdk source code from Github to compile the library files of the windows platform. It seems that I have not found the file you said. Can you say more in detail? Thank you very much.

Or are you talking about this file ?(The file name was originally OPT9220.DML. But since the .dml file can't be uploaded, I rename it to OPT9220.txt)

If it is not this file, please give me a file instance.

Thank you every much for helping me with my study! it is every important to me.OPT9220.txt

Hi!

Which software are you using to visualize phase and amplitude? It does not look as if you're using VoxelSDK/ Voxel Viewer.

OPT9220 is an older controller - we do not support this anymore. Are you using the RTS5825 camera or OPT8241-CDK_EVM?

By register settings, I mean, please read all registers from the Camera and send them as a text file. We do not require the dml file.

Suramya

Hello Suramya:
The software is written by myself using the API of voxelsdk .Hardware devices are OPT8241-CDK_EVM and OPT9220.
Suddenly I was struck with an idea that because the voxelsdk I got on Github is the latest released version while the latest voxelsdk.conf file and .dml file dosen't support OPT9220 anymore--that's why my image has so much noise. I used to use the latest voxelsdk to light up the OPT8320 but failed. Then I changed the .conf file and the .dml file to v0.6.9 and it was lit up successfully. If that is possible, which version of the configuration file supports OPT9220?

About reading all regisiters from the camera, it takes some time and I will send you later.

Many thanks for your help.

Hi,

There are a few things that we would like to clarify:

1. Noise in the image is most probably because of the hardware and settings. Not the software. If you are able to get frames, that is the extent of the software.
2. OPT8241, OPT9220, OPT8320 are 3 separate chipsets. We first need to understand which one you are referring to. If you have OPT8241-CDK-EVM, please use voxel viewer and share a .vxl file as an image capture with us. We would like to see that first and then we can comment further. If it is not OPT8241_cdk_EVM, we would like to look at the schematics of the hardware. Can you please share your hardware schematics?

Please share the hardware schematics along with the register dump and vxl frames.

Hi Subhash:

I am really sorry, I am mixed up.The chipset is OPT9220. And I don't know how to get vxl frames.

Again sorry for my negligence

Regards!

Hi,

I just wanted some clarification. No issues!
OPT9220 is part of an old chipset with 320X240 resolution. We would recommend that you use OPT8241 + OPT9221 if it is a new design. We don't support OPT9220 for new designs.

Can you also share your schematics, layout with us?
