@veye_xumm 想在cv2使用

@veye_xumm 那我该怎么样应用才不卡呢

使用的摄像头是imx385 mipi这是我测试的代码

import sys
import time
import cv2

def read_cam():
    cap = cv2.VideoCapture("v4l2src device=/dev/video0 ! video/x-raw, format=UYVY, width=1920, height=1080, framerate=30/1 ! videoconvert ! video/x-raw, format=I420 ! appsink", cv2.CAP_GSTREAMER)
    if cap.isOpened():
        while True:
            print(time.time())
            ret_val, img = cap.read()
            print(time.time())
            print("---")
            img2 = cv2.cvtColor(img, cv2.COLOR_YUV2BGR_I420)
            
            if not ret_val:
                print("无法获取图像")
                break

            cv2.imshow("CSI Camera", img2)
            if cv2.waitKey(1) == ord('q'):
                break
    else:
        print("camera open failed")
    cv2.destroyAllWindows()
if __name__ == '__main__':
    read_cam()
    

运行结果如下，读取一次花0.2秒多，该怎么办

如果直接使用指令预览不会卡

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)NV12" ! nv3dsink sync=false

@veye_xumm ok,寄到哪

@veye_xumm 烧录系统吗？还是dtb

@veye_xumm 你好，我测试了下，还是一样，无法启动

@veye_xumm 谢谢，应该支持，支持官方刷机，可以发个我测试下

@veye_xumm
U盘启动，emmc刷了启动引导，不是官方的，是亚博的sub版

Nano b01
l4t: R32 7.3
需要使用veye-mipi-imx-385摄像头
从nvidia_jetson_veye_bsp\nvidia_jetson_veye_bsp\kernel_image\Image_l4t_r32.7.3_veyecam.tar.gz解压Image替换/boot/Image
从nvidia_jetson_veye_bsp\dtbs\Nano\JetPack_4.6.3_Linux_JETSON_NANO_TARGETS\dts dtb\VEYE-MIPI-CAM2M\tegra210-p3448-0000-p3449-0000-b00.dtb 添拷贝到/boot/veyecam/tegra210-p3448-0000-p3449-0000-b00.dtb
在/boot/extlinux/extlinux.conf文件，最下面增加如下一行
FDT /boot/veyecam/tegra210-p3448-0000-p3449-0000-b00.dtb
重启如下图所示无法启动

注释掉FDT /boot/veyecam/tegra210-p3448-0000-p3449-0000-b00.dtb才能启动
