OpenMV Cam M7 (Python scripts)

OpenMV Cam M7 (Python scripts)

The OpenMV Cam makes machine vision applications a reality. Thanks to MicroPython Operating System you can programm the OpenMV Cam using high-level Python scripts. That way you can take full adjantage of the powerful Python language and its capabilities with machine vision algorithms. Despite the use of Python you still can full control over your OpenMV Cam and its I/O pins.

Détails

Features:

  • The STM32F765VI ARM Cortex M7 processor running at 216 MHz with 512 KB of RAM and 2 MB of flash. All I/O pins output 3.3 V and are 5 V tolerant. The processor has the following I/O interfaces:
    • A full-speed USB (12 Mbs) interface to your computer. Your OpenMV Cam will appear as a Virtual COM Port and a USB Flash Drive when plugged in.
    • A microSD Card socket capable of 100 Mbs reads/writes which allows your OpenMV Cam to record video and easy pull machine vision assets off of the μSD card.
    • An SPI bus that can run up to 54 Mbs allowing you to easily stream image data from the system to either the LCD Shield, the WiFi Shield, or another microcontroller.
    • An I2C Bus, CAN Bus, and an Asynchronous Serial Bus (TX/RX) for interfacing with other microcontrollers and sensors.
    • A 12-bit ADC and a 12-bit DAC.
    • Three I/O pins for servo control.
    • Interrupts and PWM on all I/O pins (there are 10 I/O pins on the board).
    • And, an RGB LED and two high power 850nm IR LEDs.
  • The OV7725 image sensor is capable of taking 640 x4 80 8-bit Grayscale images or 640 x 480 16-bit RGB565 images at 60 FPS when the resolution is above 320 x 240 and 120 FPS when it is below. Most simple algorithms will run at above 30 FPS. Your OpenMV Cam comes with a 2.8 mm lens on a standard M12 lens mount, which you can replace yourself with more specialized lenses.

Applications

  • Frame Differencing: Detect motion in a scene by looking at what's changed.
  • Color Tracking: Detect up to 16 colors at a time in an image.
  • Marker Tracking: Detect groups of colors instead of independent colors.
  • Face Detection: Detect Faces
  • Eye Tracking: Detect someone's gaze.
  • Optical Flow: Detect translation of what your OpenMV Cam is looking at.
  • QR Code Detection/Decoding: You can use the OpenMV Cam to read QR Codes in its field of view.
  • Data Matrix Detection/Decoding: Detect and decode data matrix 2D barcodes.
  • Linear Barcode Decoding: Decode 1D linear bar codes.
  • AprilTag Tracking: Track AprilTags at 160x120 at up to about 12 FPS.
  • Line Detection: Infinite line detection and non-infinite length line detection segments.
  • Circle Detection: Detect circles in the image.
  • Rectangle Detection: Detect rectangles using our AprilTag library's quad detector code.
  • Template Matching: Detect when a translated pre-saved image is in view.
  • Image Capture: Capture up to 640x480 Grayscale/RGB565 BMP/JPG/PPM/PGM images.
  • Video Recording: Record up to 640x480 Grayscale/RGB565 MJPEG video or GIF images.
