It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flowchart of an evaluation method of a driver monitoring apparatus according to an embodiment of the present invention. Referring to fig. 1, a method of evaluating a driver monitoring device includes:
step 101: receiving alarm information sent by a preset data acquisition unit; the warning information includes driver action information; the alarm information is generated by monitoring the action of the humanoid robot by the monitoring device of the driver to be detected in the simulated driving environment; the data acquisition unit is used for acquiring the alarm information; wherein, the simulated driving environment includes: the method comprises the steps of simulating a vehicle running state and simulating a vehicle running light environment. It should be noted that the simulated vehicle driving state and the simulated vehicle driving light environment are not fixed and can be adjusted at any time as required, and the simulated driving environment can be adjusted for many times in the whole evaluation process so as to realize the evaluation of the driver monitoring device under different environments.
Step 102: and comparing the consistency of the driver action information with a preset test action to obtain an evaluation result of the monitoring device. Wherein, presetting the test action includes: closed eyes, yawning, gaze deviation from safe zones, abnormal head posture, answering a handheld phone and/or disengaging hands from the steering wheel, etc. It should be noted that the preset test action in the present embodiment is not limited to the above-mentioned action, and can be preset according to actual needs.
The driver action information in the method is obtained by monitoring the humanoid robot by the driver monitoring device to be detected, and meanwhile, the driver monitoring device to be detected needs to simulate the vehicle running state and simulate the action monitoring of the humanoid robot in the vehicle running relation environment. According to the method, the humanoid robot is adopted to simulate actions to evaluate the driver monitoring device, so that the repeatability and controllability of the test are improved, and the potential safety hazard in the test process is reduced. Meanwhile, the action monitoring of the humanoid robot is carried out in the simulated driving environment, the monitoring influence of the driving environment on the driver monitoring device is fully considered, the environmental adaptability of the driver monitoring device is evaluated, and the evaluation accuracy of the driver monitoring device is improved.
On the basis of the above-mentioned examples, the present application also discloses a more detailed evaluation method, as follows.
Fig. 2 is a flowchart of an evaluation method of a driver monitoring apparatus according to another embodiment of the present invention. Referring to fig. 2, an evaluation method of a driver monitoring apparatus, which is applied to an evaluator, includes:
step 201: receiving alarm information sent by a preset data acquisition unit; the warning information includes driver action information; the alarm information is generated by monitoring the action of the humanoid robot by the monitoring device of the driver to be detected in the simulated driving environment; the data acquisition unit is used for acquiring alarm information;
step 202: judging whether alarm information is received within set time;
step 203: and if not, judging that the performance of the monitoring device of the driver to be detected does not reach the standard. At this time, the driver monitoring device does not monitor the motion of the humanoid robot, and various reasons for this situation occur, for example, the driver monitoring device has too poor environmental adaptability and is affected by the surrounding environment, so that the motion of the humanoid robot is not monitored.
Step 204: receiving alarm information within set time, and judging whether the consistency degree of the driver action information and the preset test action reaches a preset standard-reaching condition or not;
step 205: if the consistency degree reaches the preset standard reaching condition, judging whether the consistency degree reaches the preset excellent standard; the specific setting of the preset standard reaching condition is not fixed, and can be percentage, score value, and specific form can be set according to actual requirements. For example, when the consistency degree is greater than or equal to 60%, the preset standard reaching condition is judged to be reached. At the moment, the consistency between the driver action information monitored by the driver monitoring device to be tested and the preset test action reaches 60%, and the driver monitoring device can monitor the driver action.
Step 206: if the consistency degree reaches a preset excellent standard, judging that the performance of the monitoring device of the driver to be detected is superior; the predetermined excellent standard is not fixed, and the specific setting needs to be set on the basis of the predetermined standard reaching condition. Taking the preset standard reaching condition as a percentage, when the preset standard reaching condition is that the consistency degree of the driver action information and the preset test action reaches 60%, and the consistency degree is required to reach more than 90%, the performance of the driver monitoring device is superior, and the preset excellent standard criterion is that the consistency degree reaches 90%.
Step 207: and if the consistency degree does not reach the preset excellent standard, judging that the performance of the monitoring device of the driver to be detected is general. The same principle as in step 206 is applied here, for example, when the degree of consistency is 60% -90%, it represents that the performance of the driver monitoring device is normal.
Step 208: and if the consistency degree does not reach the preset standard reaching condition, judging that the performance of the monitoring device of the driver to be detected does not reach the standard.
In the above embodiment, step 202 needs to determine whether the warning information is received, and this step is to evaluate whether the to-be-detected driver monitoring device fails to report. Meanwhile, after the alarm information is received, the driver action information in the received alarm information is compared with the preset test action, so that the monitoring accuracy of the driver monitoring device is evaluated.
On the basis of the above embodiment, the number of times of the received alarm information in a certain time period is compared with the number of times of the preset test action, if the two times are the same, the situation that the driver monitoring device fails to report in a missing manner is represented, and if the two times are different, the situation that the alarm in a missing manner is represented.
In the embodiment, the false alarm condition of the monitoring device of the driver to be detected is evaluated according to the total times of the actions of the humanoid robot. The evaluation method evaluates the detection rate, the accuracy rate, the false alarm rate and the missing report rate of the driver monitoring device. The comprehensiveness, the accuracy and the stability of the evaluation of the driver monitoring device are improved.

10. An evaluator, characterized in that it comprises:
a processor, and a memory coupled to the processor;
the memory is adapted to store a computer program for at least performing the evaluation method of the driver monitoring device according to any one of claims 1-5;
the processor is used for calling and executing the computer program in the memory.
