Question

我正在运行Google珊瑚提供的示例。他们在我的珊瑚板上工作得很好。然后，我按照此post之后修改了示例，以增加相机的fps输出。

平台的详细信息：

mendel@coral2:~$ uname -a
Linux coral2 4.14.98-imx #1 SMP PREEMPT Fri Nov 8 23:28:21 UTC 2019 aarch64 GNU/Linux

该示例在USB摄像机（标准摄像机）上运行良好，但是在珊瑚摄像机中会导致以下错误。（在系统日志中可见）

产生错误的步骤

git clone https://github.com/deepanshu-yadav/coral_bug.git
./ download_models.sh
cd opencv
./ install_requirements.sh
python3 detect.py

总而言之，它只读取第一帧，而从不显示后续帧。

我相信您也已经通过我们的私人支持渠道与我们联系，但是我将其粘贴到这里以供其他参考。

很遗憾，我无法使用您的代码来重现此问题。快速浏览一下代码库，您似乎尚未提交更改。另一方面，我不认为这首先会奏效。这是因为我们提供的Camera模块不支持BGR3格式，仅支持YUYV。您可以使用以下命令确认这一点：

class EditProfileForm(UserChangeForm):

    def __init__(self, *args, **kwargs):
        super(UserChangeForm, self).__init__(*args, **kwargs)

        for field in [
                    'first_name',
                    'last_name',
                    'bio',
                    'designation',
                    'university',
                    'company_name',
                    'grad_year',
                    'phone',
                    'address',
                    'city',
                    'company_category',
                    'company_desc',
                    'company_site',
                    'no_employees',
                    'technologies',
                    'markets',
                    'linkedin']:
            self.fields[field].widget.attrs['class'] = "col-lg-8 col-md-12 col-sm-12 col-xs-12 offset-lg-2 ml-6 form-control"
            self.fields[field].widget.attrs['style'] = "padding:20px;"


        self.fields['photo'].widget.attrs['class'] = "col-lg-8 col-md-12 col-sm-12 col-xs-12 offset-lg-2 ml-6"
        self.fields['password'].widget.attrs['class'] = "hidden"


    class Meta:
        model = User
        fields = ('first_name',
        'last_name',
        "photo",
        "bio",
        "designation",
        "university",
        "company_name",
        "grad_year",
        "phone",
        "address",
        "city",
        "company_category",
        "company_desc",
         "company_site",
        "no_employees",
        "technologies",
        "markets",
        "linkedin"
        )```

在珊瑚板上运行示例以及珊瑚照相机时出现未知格式错误
