[0004] At present, touch screen operation and trackball operation can be simulated by keyboard or mouse. However, for sensing operation, it needs to rely on the built-in sensor hardware equipment (such as gravity sensor, magnetic sensor, attitude sensor, etc.) device, three-axis gyroscope, etc.), in the existing simulator software, it is still impossible to simulate various sensing operation modes

The invention discloses a sensor data acquisition method and a sensor data acquisition apparatus for a three-axis gyroscope of a simulator. The sensor data acquisition method for the three-axis gyroscope of the simulator comprises the steps of acquiring posture change information of the simulator from a first posture to a second posture, wherein the posture change information comprises, in a local coordinate system of the simulator, three-axis rotation angles of the first posture in relative to a standard posture, three-axis rotation angles of the second posture in relative to the standard posture and a time interval ([Delta]t) changing from the first posture to the second posture; calculating to obtain a coordinate transformation matrix of the second posture in relative to the first posture of the simulator; solving to obtain three-axis rotation angles ([Delta]alpha, [Delta]beta and [Delta]gamma) of the second posture in relative to the first posture; further calculating to obtain the sensor data of the three-axis gyroscope; and sending the sensor data of the three-axis gyroscope to a simulation apparatus operation system module of the simulator. With the technical solution provided by the invention, simulation of sensor operation modes of the three-axis gyroscope can be realized in software of the simulator.
Description
technical field [0001] The invention relates to the technical field of simulators, in particular to a method and device for acquiring sensing data of a simulator's three-axis gyroscope. Background technique [0002] An emulator, also known as a simulator, refers to simulating the functions and operating systems of hardware devices by means of software to establish a virtual system with complete hardware functions and running in an isolated environment. There are various forms of simulators, and most common simulators are based on PCs, such as simulating various game consoles and portable devices in a PC, or even simulating another one or more PCs in a PC. The main function of the emulator, on the one hand, is to enable software on other platforms to run on a certain platform, such as playing games in game consoles on a PC; Environment, in order to facilitate data collection, bug location and so on. [0003] For the simulators of game consoles, mobile phones and other devic...
