what version of caffe that could generate Mobilenet-SSD?

Hi, i was doing research on car plate recognition recently. i downloaded the program but i couldn't find the caffe version that could compile Mobilenet-SSD suitable for this project. What is the version of caffe did you use?

final loss

can you share the final loss when, i found it large, just give me a reference, such as loc: 0.xxx, cla: 0.xx, landms 0.xx
or loc: 0.00x cla: 0.00x, landms: 0.00x

Hello

I also would like to train it with my dataset if possible to set up another model.

Where can I find the training dataset?

or if the dataset will not be published, can you tell me how many images are used in training?

How to Train for a new data set?

Also can you provide training file and alsoyour data set.

模型参数

您好，我看到这个License-Plate-Detector/weights/yolov5s.pt模型参数13918k,是不是推理速度很快？我现在数据集是目标顺时针四个点的坐标，可能需要进行那些更改

请问能否输出车辆的检测框呢。

请问能否输出车辆的检测框呢，后续想进行其他处理。谢谢

what datasets you used to train this model

Can you please tell what are the datasets you used to create train this model?

where is the file "lpd.caffemodel"

There is a code in "demo_license.py" line12 : caffe_model='lpd.caffemodel' ,
but i can't find the file "lpd.caffemodel" , there only exists a file called "lpr.caffemodel", are these two files the same just with a error spelled name?

How to install the align?

An align has been imported in your code. How to install the align?
from align import *

https://github.com/zeusees/Mobilenet-SSD-License-Plate-Detection/blob/master/detect_opencv.py#L5

I tried the following command without success.
pip install align

能否最后只检测四个角点的坐标？

你好，大佬，我是一名大二学生，目前在我们学校robomaster战队里负责用神经网络识别装甲板，但是用yolo系列的话最后的bbox并不能很好的拟合装甲板的轮廓，导致我们后期在使用pnp进行姿态解算时会有很大误差，所以我想使用关键点检测的方法得到的bbox效果要好很多，就用装甲板的四个角点，就是我看您的这个项目应该能够实现，我想问一下就是需要改动哪些地方呢，loss和head就行了吗？

单车牌检测效果好，多目标（车牌）检测出现很多漏检，误检？

retinaface 原理上是可以做多车牌检测的，为何出现使用上多车牌检测效果很不好？难道是ccpd的训练数据样本中只有一个车牌？

Kindly me the method of how to sucessfully run the files?

what exactly are version of libraries and frameworks that are required to run this project.
What changes do i need to made inorder to run it.

黄色车牌更本检测不出来，靠背了啦

多分类模型？

这个模型不是多分类的吗？能否训练一个车牌多分类的模型，包括蓝牌，大使馆牌，警牌等

训练数据集可否分享一下

您好，一直关注您的算法，这个车牌关键点检测的训练样本可否分享一下。

请教如何转为onnx

您好，我在自己学习相关的知识，然后自己修改了一下代码，但很可惜一直报错，我把detect_plate.py中的main修改如下：

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('--weights', nargs='+', type=str, default='runs/train/exp/weights/last.pt', help='model.pt path(s)')
    parser.add_argument('--image', type=str, default='data/images/test.jpg', help='source')  # file/folder, 0 for webcam
    parser.add_argument('--img-size', type=int, default=640, help='inference size (pixels)')
    opt = parser.parse_args()
    print(opt)
    device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
    # print(opt.weights)
    model = torch.load(opt.weights[0], map_location=device)['model'].float().fuse().eval()
    # model = torch.load(opt.weights)

    batch_size = 1                              # 批处理大小
    input_shape = (3, 800, 800)                 # 输入数据

    # set the model to inference mode
    # torch_model.eval()

    x = torch.randn(batch_size,*input_shape)    # 生成张量
    export_onnx_file = "test.onnx"              # 目的ONNX文件名
    torch.onnx.export(model,
                        x,
                        export_onnx_file,
                        opset_version=10,
                        do_constant_folding=True,   # 是否执行常量折叠优化
                        input_names=["input"],      # 输入名
                        output_names=["output"])

    quit()
    for filename in f:
        print(filename)
        detect_one(model, filename, device)

不过报错如下：

可以指点下吗？

Prj-ncnn版本被删除了吗？

···
cd Prj-ncnn

cmake .

make
···
我看教程中还包含这部分，但是代码中已找不到了，是ncnn版本不再维护了吗？

有没有训练用的代码或者数据集

ncnn模型精度比pytorch低很多

pytorch版大部分可以检测，ncnn版效果没那么好，尝试了不同阈值还是达不到pytorch版的效果，请问是pytorch->onnx->ncnn吗？

请问可以转换成TFLite吗

大佬看你支持很多种车牌类型的,可以分享下您的数据收集思路吗

看您支持,以下的车牌;
蓝色单层车牌
黄色单层车牌
绿色新能源车牌、民航车牌
黑色单层车牌
白色警牌、军牌、武警车牌
黄色双层车牌
绿色农用车牌
白色双层军牌

如直接搜索"白色警牌或者白色军牌"等,几十张都很难收集,更别说用于训练,可以分享下您是如何收集这些数据的数据思路吗,有什么技巧呢,GAN?

临牌有支持吗？

where is the train code ?

where is the train code ? I want to train, but there is nothing, could you give me? thank you!

如何把车牌里的内容识别出来呢 ~？
