raspberry pi_在Raspberry Pi上使用TensorFlow进行对象检测

發(fā)布時(shí)間：2023/12/15 编程问答 37 豆豆

生活随笔收集整理的這篇文章主要介紹了 raspberry pi_在Raspberry Pi上使用TensorFlow进行对象检测小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

raspberry pi

The following post shows how to train and test TensorFlow and TensorFlow Lite models based on SSD-architecture (to get familiar with SSD follow the links in the ?References? down below) on Raspberry Pi.

以下帖子顯示了如何在Raspberry Pi上基于SSD架構(gòu)訓(xùn)練和測試TensorFlow和TensorFlow Lite模型(要熟悉SSD，請遵循下面“參考”中的鏈接)。

Note: The described steps were tested on Linux Mint 19.3 but shall work on Ubuntu and Debian.

注意：所描述的步驟已經(jīng)在Linux Mint 19.3上進(jìn)行了測試，但是可以在Ubuntu和Debian上運(yùn)行。

資料準(zhǔn)備 (Data preparation)

Like in the post dedicated to YOLO one have to prepare data first. Follow the first 7 steps and then do this:

就像在專門針對YOLO的帖子中一樣，必須首先準(zhǔn)備數(shù)據(jù)。請遵循前7個(gè)步驟，然后執(zhí)行以下操作：

1. In order to get listed data and generate TFRecords clone repository ?How To Train an Object Detection Classifier for Multiple Objects Using TensorFlow(GPU) on Windows 10?:

1.為了獲取列出的數(shù)據(jù)并生成TFRecords克隆存儲庫《如何在Windows 10上使用TensorFlow(GPU)訓(xùn)練多個(gè)對象的對象檢測分類器》：

git clone https://github.com/EdjeElectronics/TensorFlow-Object-Detection-API-Tutorial-Train-Multiple-Objects-Windows-10.gitcd TensorFlow-Object-Detection-API-Tutorial-Train-Multiple-Objects-
Windows-10

2. Put all labeled images into folders ?images/test? and ?images/train?:

2.將所有帶標(biāo)簽的圖像放入“圖像/測試”和“圖像/訓(xùn)練”文件夾中：

3. Get data records:

3.獲取數(shù)據(jù)記錄：

python3 xml_to_csv.py

This command creates ?train_labels.csv? and ?test_labels.csv? in ?im-ages? folder:

該命令在?im-ages?文件夾中創(chuàng)建?train_labels.csv?和?test_labels.csv?：

4. Open ?generate_tfrecord.py?:

4.打開?generate_tfrecord.py?：

And replace the label map starting at line 31 with your own label map, where each object is assigned an ID number, for ex.:

并用您自己的標(biāo)簽圖替換從第31行開始的標(biāo)簽圖，其中為每個(gè)對象分配一個(gè)ID號，例如：

5. Generate TFRecords for data:

5.為數(shù)據(jù)生成TFRecords：

python3 generate_tfrecord.py — csv_input=images/train_labels.csv
— image_dir=images/train — output_path=train.recordpython3 generate_tfrecord.py — csv_input=images/test_labels.csv
— image_dir=images/test — output_path=test.record

These commands generate ?train.record? and ?test.record? file which will be used to train the new object detection classifier.

這些命令生成“ train.record”和“ test.record”文件，這些文件將用于訓(xùn)練新的對象檢測分類器。

6. Create a label map. The label map defines a mapping of class names to classID numbers, for ex.:

6.創(chuàng)建標(biāo)簽圖。標(biāo)簽映射定義了類名到classID號的映射，例如：

item {
id: 1
name: 'nutria'
}

Save it as ?labelmap.pbtxt?.

將其另存為?labelmap.pbtxt?。

7. Configure the object detection training pipeline. It defines which model and what parameters will be used for training.Download ?ssd_mobilenet_v2_quantized_300x300_coco.config? from https://github.com/tensorflow/models/tree/master/research/object_detection/samples/configs:

7.配置對象檢測訓(xùn)練管道。它定義了用于訓(xùn)練的模型和參數(shù)。從https://github.com/tensorflow/models/tree/master/research/object_detection/samples/configs下載 ?ssd_mobilenet_v2_quantized_300x300_coco.config?：

wget https://github.com/tensorflow/models/blob/master/research/object_detection/samples/config/ssd_mobilenet_v2_quantized_300x300_
coco.config

8. Change configuration file:

8.更改配置文件：

Set number of classes:
設(shè)置班數(shù)：

- num_classes: SET_YOUR_VALUE
-num_classes：SET_YOUR_VALUE
Set checkpoint:
設(shè)置檢查點(diǎn)：

- fine_tune_checkpoint: “/path/to/ssd_mobilenet_v2_quantized/model.ckpt”
-fine_tune_checkpoint：“ / path / to / ssd_mobilenet_v2_quantized / model.ckpt”
Set ?input_path? and ?label_map_path? in ?train_input_reader?:
在?train_input_reader?中設(shè)置?input_path?和?label_map_path?：

- input_path: “/path/to/train.record”
-input_path：“ / path / to / train.record”

- label_map_path: “/path/to/labelmap.pbtxt”
-label_map_path：“ / path / to / labelmap.pbtxt”
Set ?batch_size? in ?train_config?:
在?train_config?中設(shè)置?batch_size?：

- batch_size: 6 (OR SET_YOUR_VALUE)
-batch_size：6(或SET_YOUR_VALUE)
Set ?input_path? and ?label_map_path? in ?eval_input_reader?:
在?eval_input_reader?中設(shè)置?input_path?和?label_map_path?：

- input_path: “/path/to/test.record”
-input_path：“ / path / to / test.record”

- label_map_path: “/path/to/labelmap.pbtxt”
-label_map_path：“ / path / to / labelmap.pbtxt”

sudo apt update
sudo pip3 install tensorflow-2.2.0-cp37-none-linux armv7l.whl

Note: Experience shows that it is better to install ?wheel? rather then from pip default repository, since it does not show all the versions for Raspberry Pi:

注意：經(jīng)驗(yàn)表明，最好安裝?wheel?，而不要從pip默認(rèn)存儲庫安裝，因?yàn)樗粫@示Raspberry Pi的所有版本：

訓(xùn)練 (Training)

Note: Training shall be done on host machine to avoid additional problems that might occur on Raspberry Pi since TensorFlow framework and its accompanying software were originally developed and optimized for usage on mainframes.

注意：由于TensorFlow框架及其隨附軟件最初是針對大型機(jī)開發(fā)和優(yōu)化的，因此應(yīng)在主機(jī)上進(jìn)行培訓(xùn)，以避免在Raspberry Pi上可能發(fā)生的其他問題。

1. Install TensorFlow (for CPU or GPU):

1.安裝TensorFlow(用于CPU或GPU)：

sudo pip3 install tensorflow==1.13.1
or
sudo pip3 install tensorflow-gpu==1.13.1

Note: Use v1.13.1 since it is the most stable version for main frames and works with all other software used here (from own experience).

注意：請使用v1.13.1，因?yàn)樗侵鳈C(jī)最穩(wěn)定的版本，并且可以與此處使用的所有其他軟件一起使用(根據(jù)自己的經(jīng)驗(yàn))。

2. Get TensorFlow models:

2.獲取TensorFlow模型：

git clone https://github.com/tensorflow/models.git

3. Copy ?train.py? from folder ?legacy? to ?object_detection?:

3.將“傳統(tǒng)”文件夾中的“ train.py”復(fù)制到“對象檢測”中：

cp /path/to/models/research/object_detection/legacy/train.py
/path/to/models/research/object_detection/

4. Get pretrained model from https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf1_detection_zoo.md:

4.從https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf1_detection_zoo.md獲取預(yù)訓(xùn)練的模型：

wget http://download.tensorflow.org/models/object_detection/ssd_
mobilenet_v2_quantized_300x300_coco_2019_01_03.tar.gz

5. Unpack archive:

注意：在“ * .config”中配置了“ fine_tune_checkpoint”文件夾的文件夾中解壓縮檔案。

6. Start training:

6.開始訓(xùn)練：

python3 train.py --logtostderr -train_dir=/path/to/training/
--pipeline_config_path=/path/to/ssd_mobilenet_v2_quantized.config

Note #1: ?/path/to/training/? is any folder where all training results couldbe saved to.Note #2: If training process is suddenly terminated one can change values?num_steps? and ?num_examples? reducing the load on memory.

注意＃1： ?/ path / to / training /?是可以將所有訓(xùn)練結(jié)果保存到的任何文件夾。 注意＃2：如果訓(xùn)練過程突然終止，則可以更改值“ num_steps”和“ num_examples”，以減少內(nèi)存負(fù)荷。

7. After training has finished, the model can be exported for conversion to TensorFlow Lite using the ?export_tflite_ssd_graph.py? script:

7.訓(xùn)練完成后，可以使用?export_tflite_ssd_graph.py?腳本將模型導(dǎo)出以轉(zhuǎn)換為TensorFlow Lite：

python3 export_tflite_ssd_graph.py
--pipeline_config_path=/path/to/ssd_mobilenet_v2_quantized.config
--trained_checkpoint_prefix=/path/to/training/model.ckpt-XXXX
--output_directory=/path/to/output/directory
--add_postprocessing_op=true

Note #1: For each ?model.ckpt-XXXX? there must be corresponding ?model.ckpt-XXXX.data-00000-of-00001?, ?model.ckpt-XXXX.index?, ?model.ckpt-XXXX.meta” in the ?training? folder.Note #2: ?/path/to/output/directory? is any folder where all final results could be saved to.

注意事項(xiàng)1：對于每個(gè)?model.ckpt-XXXX?，必須有相應(yīng)的?model.ckpt-XXXX.data-00000-of-00001?，?model.ckpt-XXXX.index?和?model.ckpt-XXXX。 meta”位于“培訓(xùn)”文件夾中。 注意＃2： ?/ path / to / output / directory?是可以將所有最終結(jié)果保存到的任何文件夾。

After the command has been executed, there must be two new files in theoutput folder specified for ?output_directory?: ?tflite_graph.pb? and?tflite_graph.pbtxt?.

執(zhí)行命令后，在為“ output_directory”指定的輸出文件夾中必須有兩個(gè)新文件：“ tflite_graph.pb”和“ tflite_graph.pbtxt”。

8. Install Bazel in order to optimize trained model through the TensorFlow Lite Optimizing Converter (TOCO) before it will work with the TensorFlow Lite interpreter:

8.安裝Bazel以便通過TensorFlow Lite優(yōu)化轉(zhuǎn)換器(TOCO)優(yōu)化訓(xùn)練后的模型，然后再與TensorFlow Lite解釋器一起使用：

The contents:

內(nèi)容：

Only one class in this case在這種情況下只有一個(gè)班級

12. The model is ready for usage. Put ?detect.tflite? and ?labelmap.txt? into separate folder and use it as normal pretrained model (see ?Testing? paragraph).

12.該模型可以使用了。將“ detect.tflite”和“ labelmap.txt”放入單獨(dú)的文件夾中，并將其用作常規(guī)的預(yù)訓(xùn)練模型(請參見“測試”段落)。
