  • In OAK-1 Lite image capturing time

    we are accessing 3 cameras as below

    Let us know solution, so we can access camera & capture image in microseconds

    • In OAK-1 Lite image capturing time

      Hi All,
      We are using OAK-1 Lite camera (qty-3). Cameras interface using USB Hub (all ports are 3.0). We are using active USB cable from camera to USB hub.
      We are running image capturing code from c# code. ONLY for image capture it is taking 2.1sec.
      How can I reduce it ?
      If any api link or any other source, please share.

      • In USB to ethernet converter for OAK-1-Lite Auto Focus camera

        Does anyone have valid result of 4 USB camera with USB 3.0 HUB (each port is 3.0) & it's working well
        We need 5FPS speed of each camera.
        Because all camera will access at a time using our software

        • In USB to ethernet converter for OAK-1-Lite Auto Focus camera

          I am using OAK-1-Lite Auto Focus camera. I have to use 4 camera for my machine.
          Can I use USB to ethernet converter for each camera?
          If yes, how?
          If no, why?

          Presently I am using 3 camera with 3.0 USB hub & its working fine. But, Thinking for Ethernet converter also for OAK-1-Lite Auto Focus camera.

          • In Low cost camera with PC interface

            Hi @jakaskerl ,
            We have OAK-1-Lite. our task is to capture image from this.
            task-1: keep camera on in streaming mode & capture image.
            in this, we are getting clear image. distance between object & camera is 10cm & we changed to 12 cm.

            task-2: we have capture image directly. no streaming mode.
            in this case, image is blur. how can we resolve this.

            task-3: This is autofocus, we have to change it to fixed focus. any reference?

            we have to capture only image. suggest method/sample code for capturing image using C# api

          • In C# API for capturing image

            Hello Luxonis Team,
            We are developing solution using c#. Do you have API for C#?
            If yes, provide links.
            If not, what is other solution for this.

          • In Low cost camera with PC interface

            We are using this OAK-1-Lite inside industrial machine (machine vision system). since, CPU is kept below machine & camera is at top, distance from camera to CPU is 3 meter approx. Can you suggest any good USB cable which can send data upto 3 meter?
            I am using camera only for capturing image & later on for OCR.

            "very fast" meaning is I have to capture image in minimum possible time.
            Can I reduce any line of above code?
            or is there any another method to capture image as fast as I can?
            Threading I will use. But, need some direction or sample code.

              • In Low cost camera with PC interface

                I have purchase OAK-1 Lite.
                I have to capture only image. Its working, but I have to do it very fast.
                What are different optimization for capturing image only?

                import depthai as dai
                import cv2

                pipeline = dai.Pipeline()

                cam_rgb = pipeline.createColorCamera()
                cam_rgb.setBoardSocket(dai.CameraBoardSocket.RGB)
                cam_rgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_1080_P)
                #cam_rgb.setAutoExposureEnable(True)

                xout = pipeline.createXLinkOut()
                xout.setStreamName("video")
                cam_rgb.video.link(xout.input)

                with dai.Device(pipeline) as device:
                while True:
                frame = device.getOutputQueue(name="video", maxSize=4, blocking=False).get()
                img = frame.getCvFrame()
                cv2.imshow("OAK Image", img)


                    cv2.imwrite("C:\depthai\demo_code\save_image\captured_image.jpg", img)
    
    break

    if cv2.waitKey(1) == ord('q'):
        break

cv2.destroyAllWindows()

                    jakaskerl Yes it will work. But, how can I connect 3 camera with CPU? I mean, after connecting, will all camera will have different IP address & based on that, I will run script for respective camera or how it will be ?

                      • In Low cost camera with PC interface

                        I have to detect rubber slit from camera (rubber is cut or not) from 2 cameras. 3rd camera for character & digit recognition. These 3 cameras has to interface with PC & need to access from API.
                        Our query is, if we give trigger to camera, how can we save image in PC Hard disk directly.
                        Is this is possible?
                        We have our own software in which we have to show input & output image to client.
                        So, looking for cameras which can store images in PC Hard disk directly.
                        Cameras are going to install in automation machine which will be on factory floor
                        Do you have any such cameras?
