analyzeText: Analyze text
Function Description:
Optical Character Recognition(OCR), tesseract is used for text detection on mobile devices, Non-English language texts are supported.
General steps:
1. Download [lang].traineddata file,download address.
If you want to parse English text, you can download "eng.traineddata" file;
If you want to parse Chinese text, you can download "chi_sim.traineddata" file;
2. Upload the "*.traineddata" file.
Upload this file using the JS API "uploadTessData(fileName)".
For example:
var device = Device.getMain();
var ret = device.uploadTessData("E:\\File\\ocr\\eng.traineddata");
3. Using this interface, analyze text.
Corresponding JS API:
analyzeText(x1, y1, x2, y2, lang, mode)
Whether to support multiple devices:
No
Resource Information:
Method | GET |
---|---|
URL | .../devices/:device/screen/texts?rect=:rect&lang=:lang&mode=:mode |
Requires authentication? | Yes |
Method Parameters:
Parameter | Type | Required | Description |
---|---|---|---|
device | String | Yes | ID value of the master device |
rect | String | Yes | Screen coordinates, For example: [0,100,500,600] |
lang | String | Yes | Text detection on mobile devices, choose the corresponding language as needed; For example, [lang].traineddata, if you use the eng.traineddata file, The value of this lang is eng. |
mode | String | Yes | Analyze text mode: singleline: A single-line text in the same line multiline: The multi-line text singlechar: Single char singleword: Single word singlecolumn: The text of the same size in the same column multicolumn: The text are spread multiple column number: number noorder: The text has no order. |
Response Parameters:
A JSON string representing an array of objects with the following fields:
Field | Type | Description |
---|---|---|
status | Boolean | Return true for success and null for failure |
value | String | If the value of status is true,it returns <analyze text>; If the value of status is a null object, an error message is returned. |
Request Example:
http://localhost:8090/TotalControl/v1/devices/device@1116106541/screen/texts?token=270eq7lXQK8bXYsJ&rect=[100,200,300,400]&lang=eng&mode=singleline
Response Example:
If this API executes successfully, it returns:
{
"status": true,
"value": "<Analyze text>"
}
If the value of HTTP status code is 200, but the value of status is a null object, it returns:
{
"status": null,
"value": "<Error message>"
}
Example:
Analyze text in the screen coordinate area (7,355,680,622)
The screen content is as shown below:
Warm tip:
Get the token needed for Total Control script development,see here.
Get the id value of the master device, see here.
RingoJS Example:
// Import the packages
var {request} = require("ringo/httpclient");
var base64 = require("ringo/base64");
// The username and password are separated by a single : and sent on the wire base64 encoded
var userpass = base64.encode("sigma:3D391497");
// First step: Get the API token
var gettoken = request({
method: "GET",
url: "http://localhost:8090/TotalControl/v1/login",
headers: {
"Authorization": userpass
}
});
var ret_token = JSON.parse(gettoken.content);
var token = ret_token.value.token;
print("//The value of token is:" + token);
// Second step: Get the device id value of the master device
var getdevice = request({
method: "GET",
url: "http://localhost:8090/TotalControl/v1/devices/main?token=" + token
});
var device = JSON.parse(getdevice.content).id;
print("//The value of device ID is:"+ device);
// Third step: Execute this REST API
var resp = request({
method: "GET",
url: "http://localhost:8090/TotalControl/v1/devices/" + device + "/screen/texts",
data: {
"rect": "[7,355,680,622]",
"lang": "eng",
"mode": "multiline",
"token": token
}
});
var obj = JSON.parse(resp.content);
var ret = obj.status;
if (ret == true) {
print("//Executed successfully,Return value: \n"+resp.content);
} else if (ret != true & resp.status == 200){
print("An error message is returned: "+resp.content);
} else {
print("This API failed to execute.");
}
The running result of the RingoJS:
If it executes successfully, it will return:
//The value of token is:7mXprTVH0q4DA3eN
//The value of device ID is:device@33254183
//Executed successfully,Return value:
{"status":true,"value":"RSTA offers elite competitive\ntennis training integrated With\nRoss School’s unique academic\ncurriculum."}
