Problems solved by technology

Traditional kinematics generally adopts the method of plane terrain simulation. Due to the complex surface environment of Mars, there are a large number of stones, gravel, impact craters, etc., so the method of kinematics using plane terrain cannot really simulate the actual working state of the Mars rover in orbit.

Abstract

The invention discloses a kinematics closed-loop test system and method based on virtual reality and DEM information interaction, and belongs to the technical field of deep space probe ground system experimental testing. The method comprises the following steps: firstly, establishing a Mars surface three-dimensional topographic map by using a virtual reality system, loading a Mars rover real three-dimensional model into the three-dimensional topographic map, performing interaction of a DEM, an attitude position and time information by the virtual reality system and a kinematics module, and completing real-time transmission of camera images with a spaceborne computer at the same time. The test system effectively simulates the working environment of a Mars rover on the surface of the Mars.

Description

technical field [0001] The invention relates to a kinematics closed-loop test system and method based on virtual reality and DEM information interaction, and belongs to the technical field of deep space detector ground system experiment test. Background technique [0002] The surface environment of Mars is relatively complex, with a large number of rocks, gravel, and impact craters. How to effectively avoid these dangerous factors when the Mars rover moves on the fire surface needs to be verified by relevant algorithms during ground testing. [0003] During the ground test of the GNC sub-system of the Mars rover, GNC controls the movement of the Mars rover usually by using a kinematics module to simulate the real car body movement. The application software runs in the on-board computer, and the on-board computer performs motor The interaction between control commands and motor telemetry information completes the mobile control closed-loop test. Traditional kinematics genera...
