I got an openmv camera M7 .

1. Do u have a ros wrapper for the camera .  
[GitHub - AlexisTM/openmv\_ros: ROS driver to OpenMV camera, implementing the ROSSerial protocol. Developped for OpenMV7](https://github.com/AlexisTM/openmv_ros)
2. I want to read a specific pixel of an image .  
i know that  
sensor.snapshot(line\_filter=None) captures the image and create image object. how do i read image pixel at x,y.

thanks

Hi, we don’t have a ROS wrapper.

As for reading a particular pixel of the image. Do, img.get\_pixel(x, y).

All of this is documented in the image module documentation here: [image — machine vision — MicroPython 1.15 documentation](http://docs.openmv.io/library/omv.image.html)
