hikrobot-sdk 0.1.1

Python wrapper for Hikrobot MVS cameras

Hikrobot SDK – Python Wrapper

A lightweight, Pythonic wrapper around the Hikrobot (Hikvision Industrial) MVS Camera SDK, simplifying device enumeration, camera detection, frame grabbing, and pixel format conversion.

This package includes a wrapper for the official MvCameraControl SDK through the MvImport Python bindings.

---

⭐ Features

• Thread-safe device enumeration
• Device list caching for performance
• Find camera by serial number
• Simple CameraDevice lifecycle
• Raw frame grabbing (MV_CC_GetOneFrameTimeout)
• Convert frames to RGB
• Supports GigE & USB3 Hikrobot cameras
• Set camera parameters (int, float, bool, enum, command)

---

📦 Installation

Note: The official Hikrobot MVS SDK must be installed separately.

Install via pip:

pip install hikrobot-sdk

Ensure the Hikrobot SDK is installed:

• Linux: /opt/MVS/
• Windows: C:\Program Files\MVS\Development\

🚀 Quick Start

🔍 Enumerate Devices

from hikrobot import DeviceManager

devices = DeviceManager.enumerate()
print("Devices found:", devices.nDeviceNum)

---

🎯 Find a Camera by Serial Number

from hikrobot import DeviceManager

device_info = DeviceManager.find_camera("YOUR_CAMERA_SN")

if device_info:
    print("Camera found")
else:
    print("Camera not found")

---

📷 Open Camera and Grab a Frame

from hikrobot import CameraDevice, DeviceManager

device_info = DeviceManager.find_camera("YOUR_CAMERA_SN")
cam = CameraDevice(device_info)

if cam.create_handle_and_open():
    cam.start_grabbing()

    frame = cam.get_one_frame(1000)
    if frame:
        raw_bytes, info = frame
        print("Frame:", info.nWidth, "x", info.nHeight)

    cam.stop_grabbing()
    cam.close_and_destroy()

---

🎨 Convert Raw Frame to RGB

raw_bytes, info = cam.get_one_frame()
rgb_bytes = cam.convert_to_rgb(raw_bytes, info)

---

🔧 Set Camera Parameters

cam.set_value("ExposureTime", 12000)
cam.set_value("Gain", 5)
cam.set_value("TriggerMode", 1)
