Embodiment 1

[0046] refer to figure 1 , in this embodiment, the most basic test field configuration required for testing traffic gestures such as stop and pull over is proposed first. Including the test road 1, the test road is at least a single lane; the test road 1 is equipped with a traffic police gesture device 2, and the video surveillance camera 6 is reasonably arranged; the test field is equipped with a data center 4.

[0047] The specific process of the parking gesture recognition test. The test vehicle 3 enters the test road 1. The data center 4 establishes a communication connection with the traffic police gesture device 2 and the test vehicle 3. After the connection is successful, the test task is issued, and the traffic police gesture device 2 and the test vehicle 3 receive the task. Start to execute the test instruction after the instruction, for the traffic police gesture device 2 task instruction is to enter the parking gesture test, for the test vehicle 4 task instruction i...

Embodiment 2

[0056] refer to figure 2 , in this embodiment, the most basic test field configuration required for testing traffic gestures such as changing lanes and slowing down is first proposed. Including test road 1, the test road has at least two lanes; traffic police gesture device 2 is placed on test road 1, and video surveillance cameras 6 are arranged reasonably; data center 4 is configured on the test site.

[0057] The specific process of the test can refer to Embodiment 1. In the lane change test, after the test vehicle 3 recognizes the lane change traffic gesture made by the traffic police gesture device 2, the correct driving operation is to slow down and change lanes. In the deceleration chronic test, after the test vehicle 3 recognizes the slow-moving traffic gesture made by the traffic police gesture device 2, whether it is in the same lane or an adjacent lane, the correct driving operation is to slow down and pass through the lane.

[0058] The data analysis method is th...

Embodiment 3

[0060] refer to image 3 , in this embodiment, the most basic test field configuration required for traffic gestures such as going straight and turning is first proposed. Including the test road 1, the test road 1 has at least two lanes; the intersection 5 is an intersection; the traffic police gesture device 2 is placed at the center of the intersection 5, and the video surveillance camera 6 is reasonably arranged; the test field is equipped with a data center 4.

[0061] The specific implementation process of the test can refer to embodiment 1. In the straight test, after the test vehicle 3 recognizes the straight traffic gesture of the traffic police gesture device 2, the correct driving operation is to pass the intersection 5 without changing lanes along the current lane; ) in the turning test, after the test vehicle 3 recognizes the right (left) turning traffic gesture of the traffic police gesture device 2, the correct driving operation of the tested vehicle 3 in the rig...

Abstract

The invention discloses a test system and method of an ability of an unmanned vehicle to recognize traffic command gestures. The test system of the ability of the unmanned vehicle to recognize the traffic command gestures comprises a traffic police gesture device and a data center; the data center communicates with the traffic police gesture device and a vehicle to be tested separately; the traffic police gesture device comprises a control unit, an action execution unit, a video recording unit and a remote communication unit; the control unit is connected to the action execution unit, the video recording unit and the remote communication unit separately; and the data center simultaneously receives data of the traffic police gesture device and the vehicle to be tested during the test process, so as to evaluate the cognitive ability of the vehicle to be tested. The beneficial effect of the invention is that: the test data is monitored and collected comprehensively through the data center, and the ability of the vehicle to be tested is comprehensively and objectively graded through the data of the traffic police gesture device and the vehicle to be tested.

Description

technical field [0001] The invention relates to the field of unmanned driving technology, in particular to a test system and method for an unmanned vehicle's ability to recognize traffic command gestures. Background technique [0002] Unmanned driving is the product of the deep integration of the automotive industry with new-generation information technologies such as artificial intelligence, the Internet of Things, and high-performance computing. It is the main direction for the development of intelligence and networking in the global automotive and transportation fields. At present, the United States, Europe, Japan, and my country not only support unmanned driving technology in terms of policy, research, and technology development, but also vigorously build smart car test demonstration areas. Solve the technical problems in the actual operation of intelligent networked vehicles through test evaluation and demonstration application methods, promote the development of unmann...
