OpenMV固件源码
* Added pooling functions to make getting small images easy. set_binning works too... but, it zooms in way to much. pooling functions aout you to shrink the image while not zooming in. * To make the pooling functions easy to use I created a version that pools the image out of place and one that pools the image in place. The inplace pooling function can work on the frame buffer (see edits to sensor.c) * I added the code to do hann windowing to the FFT lib. However, I commented it out after it improved performance by basically zero. Specialized windowing stuff will only come in handy for folks trying to tune their algorithm... not in general for everything. * I added subpixel resolution for the phase correlation code. You can now track the image movement really precisely. Additionally, I fixed up the displacement outputs to give expected results. I also added a QoR output for the displacement code so that you can know when the results are bad. * Finally, an example script has been added to show off the features. |

###OpenMV (Open Machine Vision Module)
OpenMV is an open-source tiny machine vision module based on the STM32F4xx ARM Cortex-M4 MCU and the OV2640 JPEG sensor.
OpenMV is programmable in Python3 (MicroPython) and capable of doing face detection and tracking, keypoint extraction, color tracking and more..The board has USB, a uSD connector and an expansion header (USART/SPI/I2C).
A Python IDE with syntax highlighting is available for the camera, it can run/upload scripts to the camera, view the framebuffer and update the firmware.
