Description

Camera testing efficiency improving method

Technical Field

The invention relates to the field of camera testing, in particular to a method for improving the camera testing efficiency.

Background

With the vigorous development of the image camera industry, the respective competition in the fields of mobile phone, vehicle-mounted and security protection main camera industries is intensified, the camera quality and performance are required to be higher, and the camera itself has more and more calibrated projects, such as the problems that the testing time of a plurality of stations such as MMI, HDCV, HDC, Lens shading, PMA and the like which are related to the test of the flagship project in the mobile phone industry is long and a third party library is used; meanwhile, with the increase of mobile phone elements and the increase of whiteboard detection items, the calculation time of the calculated data amount is greatly increased, and with the improvement of quality function requirements, the number of test items of a client is increased, so that the number of station positions is increased, the time consumption of a single station position is higher and higher, and higher equipment investment under the same productivity condition is brought due to the fact that more equipment is higher in price.

Disclosure of Invention

Aiming at the problems, the invention provides a method for improving the testing efficiency of a camera, which can effectively shorten the calculation time during the testing of the camera, thereby improving the testing efficiency and reducing the equipment investment.

The technical scheme is as follows: the utility model provides a camera efficiency of software testing promotes way which characterized in that: the method comprises the steps of shooting images through a camera, transmitting the shot image data to a server computer for storage, transmitting the shot image data to a test computer through a wireless local area network for calibration to calibrate bad data, transmitting the calibrated image data to the server computer to achieve calibration calculation, and burning the calculated data into a memory of the camera.

It is further characterized in that:

the cameras shoot a plurality of images, each camera has a unique ID address, so that the shot images are numbered in sequence, and then the numbered image data are respectively stored in the server computer;

the image shot by the camera is a non-full image pixel image.

The invention has the advantages that the camera shoots images, then the shot image data is transmitted to the server computer for storage, meanwhile, the shot image data is transmitted to the test computer through the wireless local area network for calibration so as to calibrate bad data, the calibrated image data is transmitted to the server computer to realize calibration calculation, and then the calculated data is burnt into the memory of the camera so as to facilitate subsequent operation, thereby realizing the separation of image shooting and calculation, saving the calculation time during the test of the camera, improving the test efficiency, reducing the equipment investment, being effectively suitable for stations with larger calculation amount and time consumption, and also being suitable for a third library with longer time consumption.

Detailed Description

A camera test efficiency improving method comprises the steps of shooting images through a camera, transmitting shot image data to a server computer for storage, and transferring the shot image data to a next operation station in a parallel flow mode, meanwhile, transmitting the shot image data to a test computer through a wireless local area network for calibration so as to calibrate bad data, starting calibration calculation after the calibrated image data are transmitted to the server computer, and burning the calculated data into a memory of the camera.

The system comprises a server computer, cameras, a server computer and a server computer, wherein the cameras shoot a plurality of images, and each camera has a unique ID address so as to conveniently carry out sequence numbering on the shot images, and then the numbered image data is respectively stored in the server computer; the image shot by the camera is a non-holographic pixel image.

The server computer may implement the following functions:

1) transmitting the image data (MD5 verification) and the parameters through a TCP/IP protocol grpc;

2) unpacking the data sent by the server;

3) storing test command data into a global queue, and processing the first-come data in a stack pressing mode;

4) acquiring queue data and calling an external library corresponding to a process;

5) the generated data is associated with the Sensor ID and stored in an MAP form for a test host to take;

6) and returning the result data to the MES/shopfolor system after the test result of the currently received data is associated with the Sensor ID.

Taking HDCV as an example, when double-shot images or multiple-shot images are shot at three different angles aiming at corresponding products, firstly, image data are transmitted to a server computer through a local area network, meanwhile, the shot image data are transmitted to a test computer through a wireless local area network for calibration, bad data are calibrated and gathered, the local area network is established in the whole production line, the wireless transmission speed is accelerated along with the development of technologies such as WIFI6, and the time required by a gigabit Ethernet for transmitting the HDCV station of one double-camera is less than 1S by taking 1200 ten thousand pixels as an example; because of the unique camera ID, the corresponding picture is conveniently marked as the unique picture, the time required for testing one machine is 163.4S generally in the HDCV running mode, and through the above mode, the time for shooting is 24S, when the time for burning the image is 5.5S, if the time required for uploading the image to another computer is less than 1S, the total time consumption is reduced from 163.4S to 30.5S, and the efficiency can be improved by about 5 times.

In the whiteboard test example, the current test time is about 56S, but in the above manner, the time for image shooting is only 4S, and only one image needs to be shot, and the other is the calculation waiting time, so that the efficiency is greatly improved by adopting the method.

The invention starts to calculate when the server computer receives the image data transmitted by the testing computer, and the calculating time of the server computer is just coincided with the image circulation time, thereby achieving the purpose of accelerating the circulation speed of the whole line product.
