Is it feasible to use a zed binocular camera on jetson nano?

[Shame-fight]

Is it possible to run yolov3-tiny with a zed stereo camera on nano, outputting the distance of the target Like this LD_LIBRARY_PATH =. /: $ LD_LIBRARY_PATH ./uselib data / coco.names cfg / yolov3-tiny.cfg yolov3-tiny.weights zed_camera

Yes, it should work: https://www.stereolabs.com/blog/announcing-zed-sdk-for-jetson-nano/

Hi,I have compiled and passed darknet on jetson nan. Although there are many warnings, it is successful. The uselib file is generated. My makefile is as follows:

GPU=1 CUDNN=1 CUDNN_HALF=0 OPENCV=1 AVX=0 OPENMP=0 LIBSO=1 ZED_CAMERA=1 # ZED SDK 3.0 and above ZED_CAMERA_v2_8=0 # ZED SDK 2.X

But when I execute this command: LD_LIBRARY_PATH =. /: $ LD_LIBRARY_PATH ./uselib data / coco.names cfg / yolov3-tiny.cfg yolov3-tiny.weights zed_camera ,I get the error shown below:

object names loaded GStreamer: Error opening bin: no element "zed_camera" input image or video filename: Video size: [0 x 0] exit_flag: detection_data.cap_frame.size = [0 x 0] t_cap exit t_prepare exit t_write exit t_network exit t_draw exit t_detect exit OpenCV Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /home/nvidia/build_opencv/opencv/modules/highgui/src/window.cpp, line 331 terminate called without an active exception Aborted (core dumped)

I don't know what to do to solve this problem.Nano comes with CUDN10, cudnn7.5.0, opencv3.3.1.zed_sdk version:ZED_SDK_Tegra_JP42_v3.1.0.run I am looking forward to your reply.thank you very much.from your loyal fan.

Did you compile Darknet with LIBSO=1 ZED_CAMERA=1 https://github.com/AlexeyAB/darknet/blob/master/Makefile#L8

yes,I did it.when I use this command: LD_LIBRARY_PATH =. /: $ LD_LIBRARY_PATH ./uselib data / coco.names cfg / yolov3-tiny.cfg yolov3-tiny.weights zed_camera whether I connect the zed camera or not,the error will appear

should I carry out this commond:sudo apt-get install gstreamer1.0 I I see a bit of a similarity in this issue:https://stackoverflow.com/questions/31202367/opencv-3-0-0-error-with-gstreamer @AlexeyAB

object names loaded GStreamer: Error opening bin: no element "zed_camera" input image or video filename: Video size: [0 x 0] exit_flag:

This error shows that you compiled without ZED_CAMERA=1 or without ZED_CAMERA_v2_8=1
