Lucas Kanade optic flow. Algorithms Overview Theory The optic flow computation from Lucas and Kanade is based on the image brightnes constancy assumption which states that for a motion (u,v) of a point in an image I the brightness of the point does not change: I(x, y, t) = I(x+u, y+v, t+1) Using first order Taylor expansion leads to the gradient constraint equation Ix u + Iy v + It = 0 This underdetermined system is solved by a least squares estimate over an image patch given by (u v)T = [Σ (Ix Iy)T(Ix Iy) ]-1 Σ It(Ix Iy)T References Lucas, B.

Algorithm An implementation of the described algorithm using integer or floating point arithmetics is provided in: "visual_processing/optic_flow/LucasKanade.hpp" "visual_processing/optic_flow/LucasKanade.cpp" The sample code computes a single optc flow vector over an image patch.

View topic - Camera specs for using FPV camera. Voltagewise you should be fine, however the current draw by the transmitter module might make this module unfeasible...
Let's see if I can get this math down (it's been a while for me too, so if anyone now reads the following and bursts out laughing, please also correct it and not just roll on the floor According to the link it puts out 200mW of transmitting power at a consumption of 320mA. The CF's Lipo provides 170mAh (so a constant current of 170mA for a duration of an hour) and flies around 8min on that, so let's assume it has an average current draw of 170mA * 60min / 8min = 1275mA.
If you now add a constant 320mA of the transmitter plus the 70mA of the camera on top of that you come out at 1665mA, which reduces flight time to just over 6min -- in ideal conditions that is. 3D-Cam FPV. Two Camera Field Sequential 3D Circuit Design. Two Camera Field Sequential 3D Circuit Design for use with Stereo Microscope By Gerald Heine Premise: Since I saw my first 3D movie, “It Came From Outer Space”, in 1953 I’ve been interested in making my own 3D movies.
I got my first 3D camera in 1954, a Bell and Howell Three Dimension Company Colorist, which I still have. I was interested in taking 3D pictures through a Stereo Microscope, but have not seen anything that could do this. The Field Sequential method of 3D works only on TV screens that use cathode ray tubes (CRT) for the display. Designing the Circuit: In setting out to build a device for taking 3D video through a microscope I looked for resources on-line.
