I have some issues that I cannot solve when I am doing fusion (calibration) for two ZED cameras. I am using Python 3.14.5, pyzed 5.3, ZED SDK 5.3, CUDA 13.
And I have two laptops with all the same settings and versions, with each laptop connected to one ZedCam.
Let me illustrate the flow of how I work with the fusion of ZedCam.
First, I run the python file (publisher.py) in the cmd of two laptops.
(here is my publisher.py)
import pyzed.sl as sl
zed = sl.Camera()
print(zed.get_sdk_version())
print(dir(sl.CommunicationParameters))
init = sl.InitParameters()
status = zed.open(init)
if status != sl.ERROR_CODE.SUCCESS:
exit()
zed.enable_positional_tracking()
body_params = sl.BodyTrackingParameters()
body_params.enable_tracking = True
body_params.detection_model = sl.BODY_TRACKING_MODEL.HUMAN_BODY_ACCURATE
body_params.body_format = sl.BODY_FORMAT.BODY_38
zed.enable_body_tracking(body_params)
comm = sl.CommunicationParameters()
comm.set_for_local_network(30000)
runtime_params = sl.RuntimeParameters()
#runtime_params.enable_fill_mode = True
#runtime_params.confidence_threshold = 95
#runtime_params.remove_saturated_areas = True
body_runtime_param = sl.BodyTrackingRuntimeParameters()
body_runtime_param.detection_confidence_threshold = 50
status = zed.start_publishing(comm)
print(“Publishing:”, status)
print(“Serial Number:”, zed.get_camera_information().serial_number)
bodies = sl.Bodies()
while True:
if zed.grab() == sl.ERROR_CODE.SUCCESS:
zed.retrieve_bodies(bodies, body_runtime_param)
if len(bodies.body_list) > 0:
print("Detected bodies:", len(bodies.body_list))
Second, I open ‘Zed360’ for the calibration (to get the calibration.json file) in one laptop and in ‘set my room’ , I type the ‘serial number’ and ‘IP Address’ of my two Zed Cameras under ‘Edge Local Network workflow (manual)’. Then I saw two cameras added to the ‘camera list’ and I pressed the button of ‘set your room’ . And I saw the 3D camera models of two ZED Cameras, however they are overlapping. I try to move one camera in real world then the 3D model of this camera is also moving, however when I move the other camera physically, it’s 3D model in ‘ZED360’ is static and it’s delta data is remain 0.00ms (I had checked with the ‘ZED Sensor Viewer’ app, this ZedCam has no problem or broke, everything in ‘ZED Sensor Viewer’ are normal). And both camera ratio detection data remain 0.000%. Also, I cannot see the skeleton of my body tracking in the ‘Zed360’. (I got some photos attached below)
I also tried to connect two ZED Cameras into one computer. In ‘Zed360’, I press ‘auto discover’ inside ‘set your room’ . Then, I saw both cameras appear on the camera list and the 3D models of two ZED Cameras were placed in the correct position, not sticking together. Also, I saw the skeleton, and the delta data also moved for two ZED Cameras. However, the ratio section data of both cameras still are 0%. Hence, I slightly adjust one ZEDcam position in the real world, then the whole ‘Zed360’ app crashes (shown not responding to Zed360’). Later, I tried everything again, however, it always showed no response.
I just followed the steps of calibration in your official website. But why did I fail? What’s the problem? Or does the ‘Zed360’ app have some bugs? As before I used the ‘ZED Explore’ to do the streaming, but it failed. The stream video just pops up once, the screen of the stream video black out. Hence, I use the samples of streamer.py and receiver.py files in the ZED Python SDK. Then streaming can probably run.
I am so confused about such issues, how can i solve these problems?
