Precautions for shooting
In mobile AP connection
,
it may cause unstable connection due to crowd density
,
and shelter
,
etc
.
Titan is not waterproof so it cannot be photographed underwater nor does it recommend photographing in rainy
weather
.
Optical flow stitching algorithm is designed to detect each pixel between frames
.
And if no similar point is found in
adjacent images
,
ripples will be generated at moving objects or lens seams
.
For example
,
in front of wallpaper of fine
vertical stripes are reflective glass or stainless steel railings
.
Therefore
,
we should try to avoid these situations and place the camera in the scene with details that are rich but non
-
repetitive
.
Safe distance
:
the safe distance of optical flow stitching is
80
cm
.
The safety distance between template stitching is
2
m
and safe distance should be considered in camera
’
s position
.
Considering the e
ff
ect of viewing through VR headset
,
it is suggested that camera lens height should be equal to an adult
height when recording video of people
,
and the distance between a character and an object should be
1.5
m
~
2
m
.
When shooting videos
,
one should ensure camera is held level
,
and it is recommended to use stabilizer when holding the
camera to shoot
.
