Embodiment Construction

[0046] Currently, methods for testing the performance of GNSS devices include but are not limited to: evaluating the performance of low-precision GNSS devices through high-precision GNSS devices. Specifically, a GNSS device with known performance (hereinafter referred to as the first GNSS device) and a GNSS device to be tested (hereinafter referred to as the second GNSS device) are installed on the experimental carrier (for example: unmanned vehicle or traditional vehicle). Carry out normal exercise, output the test data generated by the first GNSS device and the test data generated by the second GNSS device respectively during the exercise, compare the test data generated by the first GNSS device with the test data generated by the second GNSS device, Obtain the performance test report of the second GNSS device. The test report illustrates how well the second GNSS device performs relative to the first GNSS device.

[0047] When testing the performance of GNSS devices, only t...

Abstract

The invention discloses a testing device and method, a medium and electronic equipment. The testing device is used for testing positioning equipment, and comprises a power control unit, a test platform and computing equipment, wherein the power control unit is used for receiving a control signal and outputting power to the test platform according to the control signal; the test platform comprisesa bearing part and a motion limiting part; the bearing part is used for bearing to-be-positioned equipment and moves based on the power output by the power control unit; the motion limiting part is used for limiting the bearing part to move according to a preset movement track; and the computing equipment is used for receiving a positioning result output by the to-be-positioned equipment and testing the to-be-positioned equipment according to the received positioning result and the preset movement track. The testing device can guarantee that different to-be-positioned equipment is tested underthe same external condition, so that the obtained performance parameters of the different positioning equipment have comparability, and the performance of the positioning equipment can be accuratelyestimated.

Description

technical field [0001] This specification relates to the field of unmanned driving technology, in particular to a test device, method, medium and electronic equipment. Background technique [0002] With the development of unmanned driving technology, the positioning problem is a very important problem in the unmanned driving process of unmanned vehicles. GNSS (Global Navigation Satellite System; Global Navigation Satellite System), as a positioning system, is widely used in various scenarios requiring position positioning. Therefore, it has become a development trend to apply GNSS equipment to unmanned vehicles to complete the position positioning of unmanned vehicles. [0003] However, in different application scenarios, the positioning accuracy requirements for unmanned vehicles are different, which means that the GNSS devices selected by different unmanned vehicles may be slightly different. However, at present, the performance of GNSS equipment varies greatly. To selec...
