sc132清晰度问题
-
想咨询下sc132的清晰度问题。照明使用的NIR,光强够。在jetson nano上抓图,图片比较模糊,不够清晰,请问sensor有锐度等调节参数吗?
./cs_mipi_i2c.sh -r -f expostate
r exptime 26667 us, again 5.2 dB, dgain 0.0 dB

您好。- 聚焦是否需要重新调一下? 我们出厂默认是聚焦到3-5米距离。我感觉您这个图没有完全聚清晰。 您可以拧动镜头微调一下。
- 现在看参数,已经有了模拟增益了,所以图像上呈现了小麻点儿。可以尝试:
2.1. 用光圈更大的镜头。 - 2 增强一点补光。
2.3 降低帧率,达到适当增加曝光时间的目的。
ps:请问镜头用的哪款?

@veye_xumm 是不是可以把模拟增益关闭。我并不需要图像特别亮,主要清晰度差点意思。镜头是f35镜头。

可以。
你可以直接通过aeagc限制一下最大增益。
也可以调小目标亮度,aetarget。
