The VzExposureTimeParams has a member called mode. The header file for types says:

typedef struct
{
VzExposureControlMode mode;
int exposureTime; //When the control mode is AE, exposureTime represents the maximum exposure time.
//When the control mode is Manual, exposureTime represents the current exposure time.
//When the control mode is Max, exposureTime represents the maximum exposure time allowed at the current frame rate In manual exposure mode.
} VzExposureTimeParams;

while for enums:

typedef enum
{
VzExposureControlMode_Auto = 0,
VzExposureControlMode_Manual = 1,
}VzExposureControlMode;

So there is no way to set the exposure time.

In your example at https://github.com/Vzense/NebulaSDK/blob/master/Python/Samples/DS77/FrameCaptureAndSave/FrameCaptureAndSave.py, I added after line 85:

        print(frame.frameType, frame.pixelFormat, frame.exposureTime, frame.depthRange, frame.pFrameData)

It prints:

0 0 0.0 0 <API.VzenseDS_types.LP_c_ubyte object at 0x7ffb141163c0>

Why am I getting zero values for frame.exposureTime and frame.depthRange?

Are there any plans to support ROS2 Humble?

Thanks

Calling vz_cam.VZ_SetColorPixelFormat(VzPixelFormat.VzPixelFormatGray8) with any of the VzPixelFormat enum values fails with message:

  File "......./API/VzenseDS_api.py", line 145, in VZ_SetColorPixelFormat
    return self.vz_cam_lib.VZ_SetColorPixelFormat(self.device_handle, pixelFormat)
ctypes.ArgumentError: argument 2: TypeError: Don't know how to convert parameter 2

Passing it as an integer instead works.

See MWE below.

from API.VzenseDS_api import VzenseTofCam
from API.VzenseDS_enums import VzPixelFormat


def main():
    vz_cam = VzenseTofCam()
    ip = "<cam_ip_addr>"
    ret = vz_cam.VZ_OpenDeviceByIP(bytes(ip, 'utf-8'))
    if not ret == 0:
        print("No camera found")
    ret = vz_cam.VZ_SetColorPixelFormat(VzPixelFormat.VzPixelFormatGray8)
    if not ret == 0:
        print("Failed setting pixel format")
        return 1
    return 0

if __name__ == "__main__":
    main()

Running on linux x86_64 with Nebula Version: 1.1.17.834828436

I Couldn't find anything related in the release notes, but please let me know if updating will solve this issue.

Hello,

I'm working with DS77C Lite and I'm experiencing two problems:

• VZ_SetParamsByJson command (both in my code and - I guess - in NebulaGUITool) doesn't raise any exception, but it seems that it doesn't have any effect.
• frameready.confidence is always false and it is then impossible to get the related frame.

Can you support on this, please?

Many thanks!

I need help adapting code that works with the VZense DS77C Pro camera on Windows to run on my Jetson Orin with Ubuntu 20.04 AArch64. The camera's SDK is designed for Ubuntu 18.04 arm64 and uses aarch64-linux-gnu(v7.5.0) compiler.

Challenges:

1. Compatibility: The SDK isn't directly compatible with Jetson Orin's Ubuntu 20.04 AArch64 environment.

2. Compiler: The code assumes aarch64-linux-gnu(v7.5.0) compiler, which might not match Jetson Orin's compiler.

Assistance Needed:

I'm seeking guidance to:

1. Ensure the camera's SDK works with Jetson Orin's Ubuntu 20.04 AArch64 setup.
2. Make the code compatible with Jetson Orin's compiler.
3. Adapt the code for proper execution on Jetson Orin.

Steps Taken:

1. Tried running code on Jetson Orin, encountered SDK and compiler issues.
2. Explored SDK documentation and made preliminary code adjustments.

Appreciate your expert advice to achieve successful integration.

Thank you,

Hi,

I'm using DS77C Pro.

I want to get IR image with IR Illuminator off.
But the IR image which I can get by Nebura API is the IR image with IR illuminator ON.

So please let me know how to get the IR image with IR Illuminator off.

VZENSE_C_API_EXPORT VzReturnStatus VZ_RebootDevie(VzDeviceHandle device);

VZ_RebootDevie -> VZ_RebootDevice

Hi,

I'm trying to make an app using the C# wrapper and I found there are some functions not implemented:
Spatial filter - VN_SetSpatialFilterEnabled is available but VZ_SetSpatialFilterParams is not
Time filter - VZ_SetTimeFilterEnabled is not available but VN_SetTimeFilterParams is.
Can I just p/invoke these functions passing the device handle or is there anything else that happens in the wrapper code? Happy to contribute a PR to add these in if you're able to open up the wrapper source code.

Also btw I noticed VN_SetHDRModeEnabled is available but not documented in the 'VZense_NebulaSDK_User_Guide_Windows_en' document. I'm assuming we pass it 0 or 1 cast to a byte instead of a bool?

Thanks!
James

I'm able to see the output of the DS87 camera using NebulaGUITool, but I'm unable to launch the camera node properly, even after installing the catkin workspace with all dependencies! I'm using LAN and POE for connection.
I'm using Ubuntu 20.04

Hello,

I'm using ubuntu 20.04, I can't find installation instructions on how to install your libraries to be able to run ROS package.
