The technical solution of the embodiment of the present disclosure can quickly verify the sensing effect of a vehicle installed with a sensing device, and identify quality problems.
The sensing device includes, but is not limited to, a camera, a radar, an ultrasonic transceiver and other sensor for sensing a target. Illustratively, the vehicle includes, but is not limited to, autonomous vehicles and intelligent teaching vehicles.
The preset range can be set according to the type and sensing range of the sensing device to be tested, and the preset route can be set according to the preset range. For example, the moving area in which the moving apparatus moves in accordance with the preset route can cover the preset range. The type and number of sensing targets carried on the moving apparatus can be set according to a test environment, and will not be limited in this embodiment.
The moving apparatus moves in the preset range of the vehicle in accordance with the preset route. By acquiring moving data of the moving apparatus, true reference data for testing the sensing effect can be obtained. By comparing the true reference data with the sensing result data of the sensing target generated by the sensing device to be tested, the test result of the sensing effect can be obtained.
In one implementation, the true reference data includes a true position, a true orientation, a true speed, a true acceleration, a true size and a true shape of the sensing target. The sensing result data includes a sensing position, a sensing orientation, a sensing speed, a sensing acceleration, a sensing size and a sensing shape of the sensing target, generated by the sensing device to be tested.
By comparing the true position with the sensing position, comparing the true orientation with the sensing orientation, comparing the true speed with the sensing speed, comparing the true acceleration with the sensing acceleration, comparing the true size with the sensing size, and comparing the true shape with the sensing shape, respectively, the sensing effect of the sensing device to be tested can be accurately tested from a plurality of dimensions.
In one implementation, the S102 may include: acquiring the true position, the true orientation, the true speed and the true acceleration of the sensing target based on a positioning mechanism on the moving apparatus.
Illustratively, based on the positioning mechanism, the true position and the true orientation of the sensing target can be acquired in real time, and then the true speed and the true acceleration can be calculated. The true size and the true shape of the sensing target can be obtained by measuring the sensing target. Thus, all true reference information of the sensing target can be obtained conveniently and quickly in real time.
In one implementation, the true reference data are a plurality of true reference information including time identifications, the sensing result data are a plurality of sensing information including time identifications, and the S104 may include: comparing the true reference information and the sensing information with a same time identification.
That is, the true reference data and the sensing result data can be continuous data distributed at a preset time interval. Illustratively, both the true reference data and the sensing result data can be output at a frequency of 100 Hz or higher, so as to obtain a plurality of continuous true reference information including time identifications and a plurality of continuous sensing information including time identifications, respectively. By continuously comparing the true reference information and the sensing information output at each node (time identification), it is possible to obtain the test result at each node, such as pass or fail, that is, a plurality of continuous test results including time identifications. By summarizing the sensing results at all nodes in accordance with a preset test standard, the test result of the sensing effect of the sensing device to be tested can be obtained.
In one implementation, the S102 may include: collecting the movement data at a preset time interval; and generating the plurality of true reference information comprising the time identifications based on the collected movement data and the sensing target information.
For example, based on the positioning mechanism, the moving apparatus can output the movement data such as the true position, the true orientation, the true speed and the true acceleration at the frequency of 100 Hz or higher. Furthermore, in combination with the sensing target information, such as the true size and the true shape, a plurality of continuous true reference information including time identifications, that is, the true position, the true orientation, the true speed, the true acceleration, the true size and the true shape, can be quickly obtained in real time.
For each node (time identification), by comparing the true position with the sensing position, comparing the true orientation with the sensing orientation, comparing the true speed with the sensing speed, comparing the true acceleration with the sensing acceleration, comparing the true size with the sensing size, and comparing the true shape with the sensing shape, respectively, a plurality of continuous test results including time identifications can be obtained.
According to the method for testing a sensing effect of the embodiment of the present disclosure, by controlling the moving mechanism to move within the preset range of the vehicle in accordance with the preset route, the true reference data can be obtained; and then by comparing the true reference data with the sensing result data generated by the sensing device on the vehicle, the sensing effect of the vehicle installed with the intelligent sensing device can be quickly verified, and quality problems can be quickly identified.
