Problems solved by technology

Necessary information such as the movement trajectory of the test vehicle during the test and the point deduction status are still extracted through the PC software running on the PC hardware platform. Without the PC software and hardware platform, the pile test cannot be scored and judged.
[0004] Because a large amount of PC resources, especially time resources, are consumed in the process of processing image data, even though the current PC computing speed is already very high, a PC can often only manage the examination process of one pile test, which is very difficult. It is difficult to manage the test process of two or more pile tests; these are inseparable from the field pile test system of the PC, for the driver training units that have used or plan to use this type of field pile test system also had to configure its essential PCs and PC operators

Abstract

The invention discloses an automatic invigilation scoring device for a random vehicle driving test process, and a realization method thereof. The device comprises a DSP (Digital Signal Processor) digital processing unit, an embedded MCU (Microprogrammed Control Unit) microcontroller, a program storage, a data storage, a core plate and an interface bottom plate, wherein the core plate is formed by an interface connector inserting piece, the DSP digital processing unit and the embedded MCU microcontroller are used as cores of the device, namely a hardware platform, the program storage on the core plate is a hardware carrier which is used for installing an operation system and application software, the data storage is used as a temporary data storage space which is necessary to be used during operation of the system, the data storage comprises an interface buffering area with an application program, and a plurality of interfaces including electrical equipment interface component circuits and mechanical interface connectors are arranged on the interface bottom plate. By using the device, and through the cooperative operation of hardware of an embedded Linux operation system and software which operates on an embedded operating system, the automatic invigilation scoring on the random vehicle driving test process can be realized.

Description

technical field [0001] The invention relates to a test device for field driving skills of a motor vehicle driver, in particular to an automatic invigilation scoring device and a realization method for any vehicle pile test process. Background technique [0002] At present, most of the field pile test systems used in the field driving skills test for motor vehicle drivers are based on the refitted specific vehicle as the test vehicle object, and are completed by combining the software and hardware of the PC computer. In order to achieve the purpose of carrying out the pile test without refitting the test vehicle, and to meet the requirements of the new standard that any vehicle can be used as the test vehicle for the pile test, the test is obtained by collecting video scene images and analyzing and processing them. Vehicle trajectory and state information such as forward and backward, so as to obtain the corresponding basis necessary for the required scoring judgment. [000...
