How to run program on OAK-D device

Hello Gaurav3434 , device will probably communicate with the outside world in some way, eg. sending HTTP requests to a server, so you can check on the server if you get expected requests - that's how you check if it works as expected.
When pipeline is flashed, it will auto-start when it gets powered on, so you don't need to trigger/run it.
Thanks, Erik

Hello Gaurav3434 , what do you mean the program is running on your laptop?
The code that you posted has an unpopulated pipeline. As you can see, you only initialize it and flash an empty pipeline, you should add nodes/connections to it. This is how you would flash the HTTP server to the OAK POE (I assume you already flashed bootloader):

#!/usr/bin/env python3

import depthai as dai
import time

# Start defining a pipeline
pipeline = dai.Pipeline()

# Define a source - color camera
cam = pipeline.create(dai.node.ColorCamera)
# VideoEncoder
jpeg = pipeline.create(dai.node.VideoEncoder)
jpeg.setDefaultProfilePreset(cam.getFps(), dai.VideoEncoderProperties.Profile.MJPEG)

# Script node
script = pipeline.create(dai.node.Script)
script.setProcessor(dai.ProcessorType.LEON_CSS)
script.setScript("""
    from http.server import BaseHTTPRequestHandler
    import socketserver
    import socket
    import fcntl
    import struct

    PORT = 8080
    ctrl = CameraControl()
    ctrl.setCaptureStill(True)

    def get_ip_address(ifname):
        s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        return socket.inet_ntoa(fcntl.ioctl(
            s.fileno(),
            -1071617759,  # SIOCGIFADDR
            struct.pack('256s', ifname[:15].encode())
        )[20:24])

    class HTTPHandler(BaseHTTPRequestHandler):
        def do_GET(self):
            if self.path == '/':
                self.send_response(200)
                self.end_headers()
                self.wfile.write(b'<h1>[DepthAI] Hello, world!</h1><p>Click <a href="img">here</a> for an image</p>')
            elif self.path == '/img':
                node.io['out'].send(ctrl)
                jpegImage = node.io['jpeg'].get()
                self.send_response(200)
                self.send_header('Content-Type', 'image/jpeg')
                self.send_header('Content-Length', str(len(jpegImage.getData())))
                self.end_headers()
                self.wfile.write(jpegImage.getData())
            else:
                self.send_response(404)
                self.end_headers()
                self.wfile.write(b'Url not found...')

    with socketserver.TCPServer(("", PORT), HTTPHandler) as httpd:
        node.warn(f"Serving at {get_ip_address('re0')}:{PORT}")
        httpd.serve_forever()
""")

# Connections
cam.still.link(jpeg.input)
script.outputs['out'].link(cam.inputControl)
jpeg.bitstream.link(script.inputs['jpeg'])

(f, bl) = dai.DeviceBootloader.getFirstAvailableDevice()
bootloader = dai.DeviceBootloader(bl)
progress = lambda p : print(f'Flashing progress: {p*100:.1f}%')
bootloader.flash(progress, pipeline)

Hello Gaurav3434 , you can't run OpenCV on the OAK devices. We are looking into ways to add simple rectangle drawing/text drawing to the firmware. Currently, one way would be to use custom CV model, more info here.

The ColorCamera is represented with cam variable, so correct would be to use cam.initialControl.setManualFocus(130). Could you try that out?

Thanks, Erik

Hello Gaurav3434 ,
it's not that "smart", it's actually the position of the lens. Value has to be between 0-255, so in this case the lens is about halfway to the max. In case of OAK-D-POE, this value has focus from _30cm to infinity.
Thanks, Erik

I have the same problem in flashing the pipeline. The pipeline works fine with running in host PC but when I tried to make it standalone it successfully flashed but no result. I used the mqtt script in repo but changed the

with dai.Device(pipeline) as device:

print('Connected to OAK')

while not device.isClosed():

    time.sleep(1)

to

(f, bl) = dai.DeviceBootloader.getFirstAvailableDevice()

bootloader = dai.DeviceBootloader(bl)

progress = lambda p : print(f'Flashing progress: {p*100:.1f}%')

bootloader.flash(progress, pipeline, compress=True)

I didn't recieved any payload

Hi,

I want to make object traking system. I'm using just OAK-D camera and S7-1200 PLC. I will define imaginary line on the cam. If the object pass the line , camera will give data/logic 1 to PLC . How can i make it?

thanks,
