Analysis of digital recognition rate of water meter project water meter

The earliest batch of data was distributed as follows: According to teacher W said there are three kinds of water meters

Let's say that the first type

The second type of water meter is:

The third kind of water meter may be (because I am not sure)

The sample distribution in the first training set was:

A total of 8781 samples.

0 of the initial samples are: 6006 sheets

1 Sample starts with: 415 sheets

2 The beginning of the sample is: 361 Zhangquan for the second type of water meter

3 The beginning of the sample is: 620 First water meter sample + second type of water meter sample

4 The beginning of the sample is: 139 Zhangquan for the second type of water meter sample

5 The beginning of the sample is: 446 First water meter sample + second type of water meter sample

6 The beginning of the sample is: 394 Zhangquan the first Water meter sample-test samples are all the first water meters so the basic ability to identify the correct

7 The beginning of the sample is: 0

8 The beginning of the sample is: 400 Zhangquan the first type of water meter samples

9 Sample starts with: sample number is 0

Forecast 4800 samples in the test set:

The first batch tested 1700 sheets:

The second batch tested 3400 sheets:

2 of the second water meter is fully identified, but 2 of the first water meter will be 0 or other characters such as 5.

4 of the first water meter was incorrectly identified as 1 3 8, etc.

8 will identify it as 4 8 and 4.

The reason for the correct identification may be that the locator box is smaller when the location is detected:

Like to identify part of the 6 error as 5.

The second training added 3045 samples based on the first training:

respectively:

0 Add 791 first type water meter

1 Add 186 First water meter + second type of water meter

2 Add a few samples of the first water meter + most of the second water meter sample

3 543 The first sample of a water meter + the second type of water meter

4 The first sample of 243 sheets

5 402 samples of the second one

6 314 First Samples

7 66 Samples of the second one

8 38 First Samples
