㉓AW-H3 Linux驱动开发之mipi camera(CSI)驱动程序

本次说一下mipi camera的驱动开发,平台用的是全志的H3芯片,项目代号:sun8iw7p1,这次使用运行在H3上面的Ubuntu进行验证的.

Linux代码:https://github.com/orangepi-xunlong/orangepi_h3_linux

MIPI: MIPI联盟由ARM、诺基亚、意法半导体和德州仪器发起成立,作为移动行业领导者的合作组织,MIPI目的是把手机内部的接口如摄像头、显示屏接口、射频/基带接口等标准化,从而减少手机设计的复杂程度和增加设计灵活性。MIPI联盟下面有不同的WorkGroup ,分别定义了一系列的手机内部接口标准,比如摄像头接口CSI、显示接口DSI、射频接口DigRF、麦克风/喇叭接口SLIMbus等。统一接口标准的好处是手机厂商根据需要可以从市面上灵活选择不同的芯片和模组,更改设计和功能时更加快捷方便。

CSI: CMOS Sensor Interface,串行相机接口,CSI接口通常从CMOS Sensor、Video Encoder和其它视频输出设备收集数据。

CSI-1
相机最初的标准MIPI接口。它作为一种架构来定义相机和主处理器之间的接口。其继任者是MIPI CSI-2和MIPI CSI-3,两个标准仍在不断发展。
CSI-2
规范于2005年发布。它使用D-PHY或C-PHY(这两个标准均由MIPI联盟设定)作为物理层选项。该协议分为以下几个层次：
物理层(C-PHY / D-PHY)
车道合并层
低层协议层
像素到字节转换层
应用程序层
CSI-3
高速双向协议,主要用于多层对等基于UniPro的M-PHY设备网络中摄像机和主机之间的图像和视频传输。它最初于2012年发布,并于2014年在1.1版本中重新发布。

本次使用的是上海格科微的GC2035的camera,2M pixel(1616V x 1232H),框架如下:

分为两部分一部分是CSI控制器,一部分是CCI控制器,其中CCI控制器,我们这里使用其I2C部分,其它用的都是CSI部分.

我们先来了解一下camera的一些基础知识(参考:https://blog.csdn.net/radianceblau/article/details/76460907):

曝光三要素

光圈大小: 光圈就是指曝光瞬间开孔多大;
快门速度: 快门速度就是指快门开启的时间;
感光度(ISO): 感光度是指图像传感器对光线的敏感程度。

1.光圈

光圈是一个用来控制光线透过镜头,进入机身内感光面光量的装置,它通常是在镜头内。表达光圈大小我们是用f值。对于已经制造好的镜头,我们不可能随意改变镜头的直径,但是我们可以通过在镜头内部加入多边形或者圆形,并且面积可变的孔状光栅来达到控制镜头通光量,这个装置就叫做光圈。
光圈F值 = 镜头的焦距 / 镜头光圈的直径
完整的光圈值系列如下：

1/1.0，1/1.4，1/2.0，1/2.8，1/4.0，1/5.6，1/8.0，1/11，1/16，1/22，1/32，1/44，1/64

光圈的档位设计是相邻的两档的数值相差1.4倍(2的平方根1.414的近似值)相邻的两档之间,透光孔直径相差根号2倍,透光孔的面积相差一倍,底片上形成的影像的亮度相差一倍,维持相同曝光量所需要的时间相差一倍。

当光圈开得越大;背景虚化效果越明显,小光圈背景虚化效果则越不明显。在拍摄时,背景越虚化,主体突出就越明显,相对于一些人像、静物运用比较多。如果你需要烘托环境,不希望背景虚化到什么都看不清,那么采用小光圈,大景深就更适合了。

2、快门速度：

用时间表示。30s，15s，8s，4s，2s，1s，1/2 1/4 1/8 1/15 1/30 1/60 1/125 1/250 1/500 1/1000 1/2000.......
同样相邻的快门速度相差一档曝光量。很明显,数值上相差一倍。

简单的说就是：当你改变快门速度的同时也意味着改变了运动物体成像的方式(是否叠加)。快门速度越慢,运动物体越模糊;速度越快,运动物体越清晰。

3、ISO感光度：

国标表示ISO100 200 400 800 1600 3200 6400....
同样相邻的ISO相差一档曝光量。很明显,数值上成2的级数。
ISO越大噪点越明显,画质越差;但ISO提高可以使用小光圈或提高快门速度,有利于摄影师意图的实现。

摄像头构成

1,镜头: 就是凸透镜用来成像
2,对焦马达: 用来调整焦距
3,红外滤光片: 用来滤除红外光,调整光线摄入角度为直角,来达到更好的成像效果。
4,影像传感器: 核心器件，用来将光学图像转化为数字化的图片raw data。

图像传感器

图像传感器是将光信号转换为电信号的装置.

自动聚焦

自动聚焦目的是获得清晰度更高得图像。常用的聚焦方法分两类,传统的聚焦方法和基于数字图像处理方式的图像聚焦方法。传统的方式中,自动聚焦通过红外线或者超生波测距的方式来实现。数字处理方法中,自动聚焦的关键在于构造图像的清晰度评价函数。己经提出的图像清晰度评价函数苞括灰度方差、梯度能量、嫡函数和一些频域函数法。图像清晰度评价函数必须具有良好的单峰性和尖锐性,而且要计算量适度,从而可以快速的实现精准对焦。

白平衡

白平衡:字面上的理解是白色的平衡。用色彩学的知识解释,白色是指反射到人眼中的光线由于蓝、绿、红三种色光比例相同且具有一定的亮度所形成的视觉反应。摄像头并不能像人眼那样具有适应性，所以如果摄像机的色彩调整同景物照明的色温不一致就会发生偏色。白平衡就是针对不同色温条件下，通过调摄像头内部的色彩电路使拍摄出来的影像抵消偏色，更接近人眼的视觉习惯。白平衡也可以简单地理解为在任意色温条件下，摄像头所拍摄的标准白色经过电路的调整，使之成像后仍然为白色。

自动白平衡

白平衡电路自动调节红、绿、蓝增益,使得白色物体无论在任何光源下都呈白色。
手动模式：红、绿、蓝增益由手动控制。
自动模式：红、绿、蓝增益由自动白平衡电路控制。

电子快门

摄像机基本都是电子快门,概念和传统照相机中快门的概念有些出入,但基本原理都是一样的,摄像机是一秒有多少个画面,相机中的快门也是类似的.

我们来看一下板子的电路图:

结合电路图,我们看一下全志的dataset(CSI和CCI两部分):

上图是CSI的框架图,下图是CCI的框架图:

CCI这里就不说了,I2C,大家的基础,这里说说CSI,我们来看一下CSI的时序图:

从上图的figure 6-3我们可以知道,全志平台的CSI控制器支持8/10/12 bit的Sensor,我们这里是使用的8 bit,因为摄像头模组gc2035是8 bit的,下面看一下CSI寄存器的列表,具体配置列表这里就不列出来了,只列一个列表:

驱动代码我们用的是全志官方提供的linux-3.4.113,主要涉及到v4l2和具体Sensor的相关数据及提供给v4l2使用的API的实现.这部分代码在:linux-3.4.113/drivers/media/video/sunxi-vfe,这里代码编译后会生成一些.ko的文件,其中vfe_v4l2.ko和gc2035.ko就是我们要用的,vfe_v4l2.ko是v4l2的相关代码,gc2035.ko是具体Sensor的实现代码,下面我们通过Makefile文件来看这两个.ko文件的组成:

obj-$(CONFIG_CSI_VFE) += vfe_os.o
obj-$(CONFIG_CSI_VFE) += vfe_subdev.o
obj-$(CONFIG_CSI_VFE) += device/
obj-$(CONFIG_CSI_VFE) += actuator/
obj-$(CONFIG_CSI_VFE) += csi_cci/
#obj-$(CONFIG_CSI_VFE) += flash_light/
#obj-$(CONFIG_CSI_VFE) += camera_detector/obj-$(CONFIG_CSI_VFE) += vfe_v4l2.o
vfe_v4l2-y                  := csi/csi_reg.o
vfe_v4l2-y                  += csi/bsp_csi.o
vfe_v4l2-y                  += bsp_common.o
vfe_v4l2-y                  += config.o
vfe_v4l2-y                  += utility/sensor_info.o
vfe_v4l2-y                  += utility/cfg_op.o
vfe_v4l2-y                  += vfe.o
vfe_v4l2-y                  += lib/libispifneq ($(strip $(CONFIG_ARCH_SUN9I)),)
vfe_v4l2-y                  += lib/lib_mipicsi2_v2
else ifneq ($(strip $(CONFIG_ARCH_SUN8IW6)),)
obj-$(CONFIG_CSI_VFE) += vfe_v4l2.o
vfe_v4l2-y                  += mipi_csi/bsp_mipi_csi.o
else ifneq ($(strip $(CONFIG_ARCH_SUN8IW8)),)
obj-$(CONFIG_CSI_VFE) += vfe_v4l2.o
vfe_v4l2-y                  += mipi_csi/bsp_mipi_csi_v1.o \mipi_csi/protocol/protocol_reg.o \mipi_csi/dphy/dphy_reg.o
else
obj-$(CONFIG_CSI_VFE) += vfe_v4l2.o
vfe_v4l2-y                  += lib/lib_mipicsi2_v1
endif

可以看到vfe_v4l2.ko的组成文件是很多的,上面的这些个文件会编译到一起组成它,可见还是比较复杂的,其中vfe.c这个文件是入口. gc2035.ko这个文件则只有gc2035.c组成,这部分是需要我们去实现,不过格科微已经提供了,主要是实现camera寄存器的初始化,然后实现v4l2需要使用的一些API.

我们再看一下v4l2的框架:

在Android上,要稍微再复杂一点,所以这里用Linux + Ubuntu core来测试,不过这里贴一个Android上的架构,毕竟这个是目前比较流行的方式,架构如下:

下面把vfe.c的内容贴出来:

因为篇幅问题,具体Sensor需要实现的内容,这里就不贴出来了,如果需要看,可以到上前面给的连接里面看代码,位置在: linux-3.4.113/drivers/media/video/sunxi-vfe/device/gc2035.c

验证的话,如下:

1).cd /lib/modules/3.4.113/kernel/drivers/media/video/sunxi-vfe/device

sudo modprobe gc2035 // 注意,不要加.ko后缀

2).cd /lib/modules/3.4.113/kernel/drivers/media/video/sunxi-vfe/

sudo modprobe vfe_v4l2 // 注意,不要加.ko后缀

3).sudo apt-get --fix-missing install motion

4).sudo nano /etc/motion/motion.conf

找到这个选项,填off, strean_localhost off

5).mkdir ~/motion

chmod 777 motion

6).sudo nano /etc/default/motion

把选项改成: start_motion=yes

7).sudo /etc/init.d/motion start

8).在局域网浏览器中输入: $(板子IP):8081,比如192.168.1.103:8081,就可以看到实时图像了.

详细可参考如下链接:
