关于图像偏移问题

我正在使用origin nano,使用v4l工具采集了28961880的一张图片

图片
图片1728×894 77.1 KB

但是为什么图片的右边16个字节像是左边偏移过来的,这个右边的16字节看起来不太对
这是我设备树中的配置方法
mode0 { / IMX219_MODE_3280x2464_21FPS */
mclk_khz = “24000”;
num_lanes = “2”;
tegra_sinterface = “serial_a”;
phy_mode = “DPHY”;
discontinuous_clk = “no”;
dpcm_enable = “false”;
cil_settletime = “0”;
lane_polarity = “3”;

				active_w = "2896";
				active_h = "1880";
				mode_type = "bayer";
				pixel_phase = "rggb";
				csi_pixel_bit_depth = "12";
				readout_orientation = "90";
				line_length = "11200";
				inherent_gain = "1";
				mclk_multiplier = "80";
				pix_clk_hz = "200000000";	

				gain_factor = "16";
				framerate_factor = "1000000";
				exposure_factor = "1000000";
				min_gain_val = "1"; /* 1.00x */
				max_gain_val = "170"; /* 10.66x */
				step_gain_val = "1";
				default_gain = "16"; /* 1.00x */
				min_hdr_ratio = "1";
				max_hdr_ratio = "1";
				min_framerate = "2000000"; /* 2.0 fps */
				max_framerate = "46000000"; /* 21.0 fps */
				step_framerate = "1";
				default_framerate = "46000000"; /* 21.0 fps */
				min_exp_time = "13"; /* us */
				max_exp_time = "683709"; /* us */
				step_exp_time = "1";
				default_exp_time = "2495"; /* us */

				embedded_metadata_height = "0";
			};

请问有什么问题吗

看起来和这个问题很像

我能怎么解决这个问题?

Yes, for current release you can try below command.

v4l2-ctl -c preferred_stride=5824

sudo v4l2-ctl -d /dev/video0 --set-fmt-video=width=2896,height=1880,pixelformat=RG12 --set-ctrl bypass_mode=0 --set-ctrl sensor_mode=0 –stream-mmap --stream-count=5 --stream-to=test9.raw -c preferred_stride=5824

Is that what you mean?
This doesn’t seem to meet my needs, the width of an image has become 5824

5

Yes it’s.
Then consider to make size 64 alignment like 2880.

Thanks

6

What does it mean? I don’t understand

7

The command is correct and the size would become 5824.
If you don’t want this solution you can have sensor output the size alignment 64 like 2880x1880
