Fig. 6a is a flowchart of a method for testing a streaming media rearview mirror according to an embodiment of the present invention; fig. 6b is a schematic diagram of a flow of a method for testing a streaming media rearview mirror according to an embodiment of the present invention. The embodiment of the invention can be suitable for testing the anti-glare mode of the streaming media rearview mirror, and the method can be executed by the streaming media rearview mirror testing equipment in the embodiment of the invention. As shown in fig. 6a, the method specifically includes the following steps:
and S610, emitting light with gradually increased intensity to the streaming media rearview mirror through the light source emitting device based on the control of the upper computer.
In the embodiment of the invention, the position of the anti-glare optical sensor of the streaming media rearview mirror needs to be firstly positioned, then the placing position of the light source emitting device is calibrated according to the position of the anti-glare optical sensor of the streaming media rearview mirror, and the light source emitting device needs to be horizontally aligned with the anti-glare optical sensor of the streaming media rearview mirror.
And S620, detecting the quality of the image displayed by the streaming media rearview mirror through an image collector to judge whether to enter an anti-dazzling mode.
And S630, recording the target intensity of the light when the streaming media rearview mirror enters the anti-dazzling mode through the upper computer, and judging whether the target intensity is consistent with the preset anti-dazzling intensity.
Specifically, the upper computer controls the light source emitting device to emit light to the streaming media rearview mirror from 0s at a frequency of increasing 1 candela every 10s, meanwhile, the image collector detects the quality of an image displayed by the streaming media rearview mirror, when the quality of the image displayed by the streaming media rearview mirror is dark, the streaming media rearview mirror is judged to enter an anti-dazzling mode, the upper computer records the target intensity of the light at the moment and compares the target intensity with the preset anti-dazzling intensity, if the target intensity is consistent with the preset anti-dazzling intensity, the anti-dazzling function of the streaming media rearview mirror is proved to be good, otherwise, the anti-dazzling function of the streaming media rearview mirror is proved to be poor, and therefore the anti-dazzling function of the streaming media rearview mirror is tested.
In an embodiment of the present invention, the functional test may be cycled 20 times to ensure the accuracy of the anti-glare capability test for the streaming media rearview mirror.
It should be noted that, in the embodiment of the present invention, it is first confirmed whether the current state of the streaming rear view mirror supports the anti-glare function. Because the streaming media rearview mirror in the embodiment of the invention has no anti-dazzling function under the condition that the streaming media function is started, the CAN bus signal needs to be detected by the upper computer, and if the streaming media function is started, namely the CAN bus signal is 1, the upper computer controls the mechanical arm device to close the key switch of the streaming media rearview mirror, so that the subsequent testing process CAN be smoothly carried out.
Therefore, the upper computer controls the light source emitting device to emit light to the streaming media rearview mirror, so that the anti-dazzling function of the streaming media rearview mirror can be tested, the problem that the test result of the streaming media rearview mirror is incomplete in the prior art is solved, and the testing method of the streaming media rearview mirror is more perfect.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
