I2c tools failed

Hi Meng,
Can you explain what parameter makes that effect with multiple shadows on image?
-
Please try close wdr.
http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_i2c/zh#wdrmodeBecause WDR uses two frames of data at different time points to be merged into one frame.
If the exposure time is long and the vehicle is fast, there will be problems in your image.You can also try to reduce ghosting by reducing the exposure time without turning off WDR. -
Ok, and which parameter controls exposure in i2c?
Like on CS?
./cs_mipi_i2c.sh -w -f aetime -p1 XXX
range:(100,1/framerate] -
@viktor
The parameters of the veye series are not as flexible as those of the cs series, and the parameter you want is mshutter. -
Ok. Have tried mshutter, but shadows presents in all cases.
If i write mshutter 0x46( 1/1000 ) i expect very short exposure and more dark image. It is ok because we are using light at night.
But at daylight frame is over exposured. So works only 0x40 (auto shutter). Then at night we have this effect: http://forum.veye.cc/post/185
Here is only mshutter auto:

Pls try close wdr as I suggested before.
-
Wdr already closed.
May be i should restart system?Pal i set before run programm.
But other controls can i set before too? -
- pls post your cmd to close wdr.
- pls try close 3d denoise.

This post is deleted! -
Here is cmd:
sudo ./veye_mipi_i2c.sh -w -f videoformat -p1 PAL
sudo ./veye_mipi_i2c.sh -w -f wdrmode -b 7 -p1 0x00
sudo ./veye_mipi_i2c.sh -w -f mshutter -b 7 -p1 0x40
So it is a daylight. Sensor has auto shutter mode, cars speed is slow because it is parking barrier.
Why is double image?

please add this one :
./veye_mipi_i2c.sh -w -f denoise -p1 x00 -b7 -
Thanks. Looks like fixed.

@viktor
OK. So 3D denoise is the key. You can try to have a low level 2d denoise. -
Thank you Meng.
-
@viktor
You are welcome.
