Callibration of Servos using OpenMV

Hello all, hope you are doing well and are safe in this unprecedented time. I am going to be building a mount for the camera that can actuate in the Yaw and Pitch directions based on Servo motors. I realize I do not have to do any feedback controls to control the servos as they are built closed loop...

Re: Two issues: White balance/blob and Flashing code into ROM

So I actually figured out the persistent ROM writing, but I would still like assistance on getting my thresholds to stay consistent. The only solution I could think of was adding 8 thresholds for the pink color I'm tracking and 8 for the green. Only concern there would be tracking more than the two ...

Good morning, I have been testing the color blob function with my system and have used snapshot to figure out which thresholds to use with my bright colors. I'm quickly realizing that I'll turn on the camera and look at the system and sometimes the thresholds work perfectly... while other times the ...

Timing and 4 sets of data

Good afternoon, I'm trying to build a project that detects the following (using two color blob detection scheme, one at the base and one at the top of the pendulum): 1) X postiion 2) X velocity 3) Angle between two blobs 4) Angular velocity For my project, there needs to be a very consistent samplin...

OpenMV H7 - Inverted Pendulum + ESP32s transmission + CRC

First of all, this is an awesome company and I'm glad I heard about it. Can't wait to try many cool and interesting projects with my new camera. I'm trying to build an embedded controls system that stabilizes an Inverted Pendulum. At first I was considering using an IMU (which I have) and a couple r...
