双MIPI摄像头图像系统设计
介绍
FPGA 的一大优势是我们可以实现并行图像处理数据流。虽然任务比较重,但是我们不需要昂贵的 FPGA,我们可以使用成本低廉范围中的一个,例如 Spartan 7 或 Artix 7。对于这个项目,将展示如何设计一个简单的图像处理应用程序,该应用程序平行处理两个摄像头。
本项目主要使用 Digilent PCAM 扩展板。PCAM 扩展板为最多四个 PCAMS 提供接口。所以只需要有FMC接口的开发板都可以完成本项目移植。

为了让系统快速启动和运行,我们将从赛灵思的一个示例项目开始设计。要打开参考项目,我们需要首先创建一个针对自己开发板上 FPGA 的项目。
![17c6d43a-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPDyAIg-TAAIAYoTMah0400.png)
打开项目后,创建一个新的BD。
![17fba408-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPD2AZYp1AAPOzmBPwKk543.png)
打开BD后,在BD中添加一个 MIPI CSI2 IP。
![182de486-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPD2AB2VqAAD9LiNtIPA184.png)
要打开参考设计,右键单击 CSI2 IP并选择打开 IP 示例设计。
![184b90a8-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPD2ADgR-AARt11yEJKE885.png)
我们将使用这个参考项目。首先要做的是移除 DSI 输出路径。这将为我们的图像处理平台释放 FPGA 中的逻辑资源。
下一步是添加以下元素以创建第二条图像处理通道。
完成的设计应如下所示:
![1875512c-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPD2AIYa4AALGsjayPdk031.png)
除了 CSI2 IP 中的设置外,第二个图像处理通道与第一个相同。
![1899e096-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPD6AWC_0AAQbPR8uFBg732.png)
原始 CSI2 IP 设置

添加的 CSI2 IP 中的设置

![19b50bea-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPD-AOJesAAO2FZTSku8790.png)
完成BD设计接下来就是针对硬件进行管脚约束。
一旦完成,我们就可以生成和构建项目并导出 XSA 用于软件开发。
该设备的利用率如下:
![19e0d5ea-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPECAcF5gAAHJaM-Laa4086.png)
软件开发
导出 XSA 后,我们可以创建一个新的 Vitis 项目,其中包含 hello world 应用程序。
从 hello world 应用程序 BSP 设置中,我们可以导入 MIPI CSI2 示例项目。
![1a039d82-647e-11ed-8abf-dac502259ad0.png](https://file1.elecfans.com//web2/M00/97/A3/wKgZomTnPECALtqOAAZQSZlA42c902.png)
我们需要对这个项目进行一些更改。
首先是通过 IIC 与传感器通信并设置传感器。板上的 CSI2 Sensor与FPGA 的 I2C 并没有直接连接。通过一个I2C BUFFER,与四个sensor连接,因为sensor的地址是一样的。
这可以在 fucntion_prototpye.c 中提供的传感器配置函数中进行更改。
所以我们在配置运行之前需要选择多路复用器。
externintSensorPreConfig(intpcam5c_mode){
u32Index,MaxIndex,MaxIndex1,MaxIndex2;
intStatus;
SensorIicAddr=SENSOR_ADDRESS;
u8SP701mux_addr=0x75;
u8SP701mux_ch=0x40;
u8PCAM_FMC_addr=0x70;
u8PCAM_FMC_ch=0x01;

if(Status!=XST_SUCCESS){
returnXST_FAILURE;
}
WriteBuffer[0]=SP701mux_ch;
Status=AdapterWriteData(1);
if(Status!=XST_SUCCESS){
printf("sp701muxfailed

returnXST_FAILURE;
}
Status=XIic_SetAddress(&IicAdapter,XII_ADDR_TO_SEND_TYPE,PCAM_FMC_addr);
if(Status!=XST_SUCCESS){
returnXST_FAILURE;
}
WriteBuffer[0]=PCAM_FMC_ch;
Status=AdapterWriteData(1);
if(Status!=XST_SUCCESS){
printf("pcammuxfailed

returnXST_FAILURE;
}
Status=XIic_SetAddress(&IicAdapter,XII_ADDR_TO_SEND_TYPE,SensorIicAddr);
if(Status!=XST_SUCCESS){
returnXST_FAILURE;
}
WritetoReg(0x31,0x03,0x11);
WritetoReg(0x30,0x08,0x82);
Sensor_Delay();
MaxIndex=length_sensor_pre;
for(Index=0;Index< (MaxIndex - 0); Index++)
{
WriteBuffer[0] = sensor_pre[Index].Address >>8;
WriteBuffer[1]=sensor_pre[Index].Address;
WriteBuffer[2]=sensor_pre[Index].Data;
Sensor_Delay();
Status=AdapterWriteData(3);
if(Status!=XST_SUCCESS){
returnXST_FAILURE;
}
}
WritetoReg(0x30,0x08,0x42);
MaxIndex1=length_pcam5c_mode1;
for(Index=0;Index< (MaxIndex1 - 0); Index++)
{
WriteBuffer[0] = pcam5c_mode1[Index].Address >>8;
WriteBuffer[1]=pcam5c_mode1[Index].Address;
WriteBuffer[2]=pcam5c_mode1[Index].Data;
Sensor_Delay();
Status=AdapterWriteData(3);
if(Status!=XST_SUCCESS){
returnXST_FAILURE;
}
}
WritetoReg(0x30,0x08,0x02);
Sensor_Delay();
WritetoReg(0x30,0x08,0x42);
MaxIndex2=length_sensor_list;
for(Index=0;Index< (MaxIndex2 - 0); Index++)
{
WriteBuffer[0] = sensor_list[Index].Address >>8;
WriteBuffer[1]=sensor_list[Index].Address;
WriteBuffer[2]=sensor_list[Index].Data;
Sensor_Delay();
Status=AdapterWriteData(3);
if(Status!=XST_SUCCESS){
returnXST_FAILURE;
}
}
if(Status!=XST_SUCCESS){
xil_printf("Error:inWritingentrystatus=%x
",Status);
returnXST_FAILURE;
}
returnXST_SUCCESS;
}
由于我们添加了第二个 Demosaic,我们还需要更新其配置。
intdemosaic()
{
demosaic_Config=XV_demosaic_LookupConfig(DEMOSAIC_DEVICE_ID);
XV_demosaic_CfgInitialize(&InstancePtr,demosaic_Config,
demosaic_Config->BaseAddress);
XV_demosaic_Set_HwReg_width(&InstancePtr,1920);
XV_demosaic_Set_HwReg_height(&InstancePtr,1080);
XV_demosaic_Set_HwReg_bayer_phase(&InstancePtr,0x3);
XV_demosaic_EnableAutoRestart(&InstancePtr);
XV_demosaic_Start(&InstancePtr);
demosaic_Config1=XV_demosaic_LookupConfig(DEMOSAIC_DEVICE1_ID);
XV_demosaic_CfgInitialize(&InstancePtr1,demosaic_Config1,
demosaic_Config1->BaseAddress);
XV_demosaic_Set_HwReg_width(&InstancePtr1,1920);
XV_demosaic_Set_HwReg_height(&InstancePtr1,1080);
XV_demosaic_Set_HwReg_bayer_phase(&InstancePtr1,0x3);
XV_demosaic_EnableAutoRestart(&InstancePtr1);
XV_demosaic_Start(&InstancePtr1);
returnXST_SUCCESS;
}
最后阶段是设置第二个 DMA,这里必须注意 DDR3地址管理以确保帧不会相互重叠。
intvdma_hdmi(){
InitVprocSs_CSC(1);
ResetVDMA();
RunVDMA(&AxiVdma,XPAR_AXI_VDMA_0_DEVICE_ID,HORIZONTAL_RESOLUTION,
VERTICAL_RESOLUTION,srcBuffer,FRAME_COUNTER,0);
RunVDMA(&AxiVdma1,XPAR_AXI_VDMA_1_DEVICE_ID,HORIZONTAL_RESOLUTION,
VERTICAL_RESOLUTION,srcBuffer1,FRAME_COUNTER,0);
returnXST_SUCCESS;
}
我们还需要注释掉 DSI 和TPG等函数使用的任何代码。
主代码也需要更新,以便在串口命令下控制 AXI Switch。

总结
该项目展示了一个MIPI摄像头接入FPGA的简单、快捷的方式,同时可以学习一下软件的导入工程的方式,简单的基于MicroBlaze系统要学会自己写控制代码,也许这就是新一代“FPGA打工人”需要掌握的一项新技术吧~(doge~不是)
