Detailed Description
At present, many camera manufacturers test cameras in a mode of collecting videos and pictures and conducting manual statistics after manually building a field environment, and the test consumes time and labor in the test process, is little in effect, is limited by weather and has certain dangers. For example, it usually takes about half a day for field personnel to install debugging equipment to begin collecting material. However, the collection of the material is relatively cumbersome, and the effective time of the collected material is often short. In addition, the collection place needs to be changed ceaselessly, the debugging equipment is installed again, the process of collecting the material again can consume a lot of time, and finally, the material analysis still needs a long time, so that the most main index analysis work of manual testing only occupies a small part of the time consumed by the whole testing work, and most of the time is used for repeated installation and debugging and material collection.
The inventor of the present application finds out ways to solve the above problems mainly including: performing algorithm test on some virtual platforms, and pouring the virtual platforms into a camera after the test is finished; or the video stream is imported through a memory card or a network port of the camera unit and then tested on the camera unit. However, in the process of performing a video stream test based on the above-mentioned manner, the inventors have found the following problems:
first, to the mode of virtual platform test, the test of camera can't be represented in the test of virtual platform, because there must exist the difference between the different platforms, often has test result and expected result inconsistent. In addition, the performance of the virtual platform is often better than that of the camera, so that the test results are different.
Secondly, aiming at the way that a memory card (such as an SD card) imports a video stream or a network port imports a video stream, the inventor finds that the running performance of the camera itself is seriously affected in the test process, because if the video stream needs to be imported from the memory card and converted into data in a YUV format, taking 25 frames per second as an example, the CPU needs to continuously read the data from the SD card, and 1920 1080 × 25 × 8bit/s (40Mbps) seriously affects the performance of the CPU, thereby destroying the accuracy of the test result. In addition, the way the video stream is imported from the portal is disruptive to CPU performance.
In view of the above problems, through long-term research and exploration of the inventor of the present application, the following embodiments are provided, and through a mode of a virtual Sensor signal, a test material can be repeatedly utilized on the basis of not changing the original operational performance of the video test equipment, so that a large number of samples can be automatically tested, the labor cost is saved, the labor cost of intelligent testing of the video test equipment is effectively reduced, the testing accuracy is improved, and the testing result has inheritance. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention.
