Problems solved by technology

In the original research on the psychological quality of drivers' safe driving, questionnaires and instruments are used to measure the research method. This method is inefficient in testing. In the process of actual use, the operator takes an average of 30 minutes to test a test subject. , each delivery center has at least 600 drivers, and it takes nearly a month to complete all the tests of a delivery center. The labor cost is expensive, the deployment is slow, the transportation cost is high, and the equipment loss rate is high
The shape of the instrument used for measurement will feel a certain amount of psychological pressure when the subject uses it, which will cause the subject's nervousness, which will lead to the test results not being objective enough, and the test that relies on the instrument is unstable.
Moreover, the statistical process is completely processed manually and requires repeated proofreading, which is prone to errors and is not conducive to the statistics and maintenance of later data.
Great obstacles to nationwide promotion

Embodiment 1

[0065] figure 1 It is a flow chart of the depth perception testing method provided by Embodiment 1 of the present invention.

[0066] refer to figure 1 , the depth perception testing method comprises the steps:

[0067] Step S110, using the 3D engine to set the scene parameters to establish a depth perception test scene;

[0068] Specifically, use the lens in the 3D engine to set the position of the camera to establish a spatial plane model; use the stage in the 3D engine to use the particle gradient function to establish an atomized environment, so that the depth perception test scene has a derivative effect and reduces the risk of being The psychological impact of the tester’s discomfort in the vast space; use the point light in the 3D engine to set up the point light material, and establish a simulated light source so that the depth perception test scene has the light effect in the real room; use the scene in the 3D engine , set the ground plane material, and establish a...

Embodiment 2

[0077] image 3 It is a flowchart of a method for establishing a depth perception test scene provided by Embodiment 2 of the present invention.

[0078] In step S110 of the depth perception test method, the scene parameters include distance parameters, output ratio parameters, atomization effects, atomization colors, point light materials, ground plane materials and attribute parameters, and the depth perception test scene includes spatial plane models, fog environment, simulated light source, 3D ground plane and wooden box model, the implementation process of step S110 includes the following steps:

[0079] Step S210, setting the distance parameter and the output ratio parameter of the camera, and establishing a spatial plane model;

[0080] Specifically, the distance parameter can be 50 unit constants in the Z-axis direction and 100 unit constants in the X-axis direction from the origin (0, 0, 0). In order to produce a visual effect from top to bottom, move the camera from ...

[0101] Figure 7 It is a schematic diagram of the depth perception testing system provided by Embodiment 3 of the present invention.

[0102] refer to Figure 7 , the depth perception test system includes:

[0103] The scene building module 100 is used to set the scene parameters by using the 3D engine to set up the depth perception test scene;

[0104] The camera setting module 200 is used to set the position of the camera to obtain the rotation mode according to the depth perception test scene;

[0105] The test module 300 is configured to perform a depth perception test according to a depth perception test scene and a rotation mode, and generate a test event;

[0106] The monitoring module 400 is configured to monitor and calculate test events to obtain test result values.

[0107] Specifically, the scene creation module 100 uses the lens, stage, point light, scene and rigid body in the 3D engine to create a depth perception test scene according to the physical laws of ...

Abstract

The invention provides a depth perception test method and system, and relates to the technical field of drivers' psychological quality evaluation. Scene parameters are set by adopting a 3D engine, a depth perception test scene is created, the position of a camera is set according to the depth perception test scene, and a rotation mode is obtained; a depth perception test is conducted according to the depth perception test scene and the rotation mode, a test event is generated, the test event is monitored and calculated, and a test result value is obtained. Accordingly, the test cost, labor cost and difficulty in operation of depth perceptions can be lowered, and the test efficiency and the test result objectivity are improved.

Description

technical field [0001] The invention relates to the technical field of driver psychological quality evaluation, in particular to a depth perception testing method and system. Background technique [0002] While the transportation industry is developing rapidly, traffic accidents have become a major public hazard. Drivers are the most important factor causing traffic accidents. Due to my country's lag in testing the suitability of professional car drivers, China has become a country with a high incidence of road traffic accidents. In the original research on the psychological quality of drivers' safe driving, questionnaires and instruments are used to measure the research method. This method is inefficient in testing. In the process of actual use, the operator takes an average of 30 minutes to test a test subject. , Each delivery center has at least 600 drivers, and it takes nearly a month to complete all the tests of a delivery center. The labor cost is expensive, the depl...
