In order to acquire an accurate initial camera pose we select the largest cluster of interest points and decompose the nonlinear optimised homography 3 (cf. [42, pp. 136]).
Reference objects such as fiducial markers and known 3D objects have also been used to get a global coordinate system, and initial camera poses are estimated by tracking reference objects.
Cudicini was wrong-footed, and it looked an awful lot like it had gone in from the initial camera angle, but in truth it had simply rebounded back into the netting off the advertising hoardings.
LM algorithm is called to optimize the initial camera parameters that are generated by genetic process previously.
Southern Electronics Supply and Active Solutions worked on the city's initial camera program and claimed the system they had developed had been misappropriated by a former technology chief for the city, Greg Meffert, and others connected to his office.
"There was no indication, from anyone on the ice, that the puck had gone in, and there was no indication from any of the initial camera angles viewed that the puck had crossed the goal line.
Comparatively, the initial camera parameters acquired through linear calibration are optimized through two different methods: one is the conventional method and the other is the novel method presented by this paper.
It still uses the trademark Quanta fabric that is very durable over time (I backed their initial camera bag and it still looks like new after years of use), but it's got a more urban commuter vibe, whereas previous packs have had more retro vibes.
On a different note, once an initial set of camera position estimates has been obtained, it may also be possible to build on an idea suggested in [31] and seek a refinement of these position estimates that minimize the overall ℓ 1 norm of the reconstructed image.
This process assumes an initial set of camera parameters and calculates the reprojection error of the images coordinates onto 3D space.
When you take a flash photo, there's an initial flash; that's the camera measuring the color temperature of the scene.
