sensor models -凯发k8网页登录

imu, gps, radar, esm, and eo/ir

model various sensors, including: imu (accelerometer, gyroscope, magnetometer), gps receivers, altimeters, radar, lidar, sonar, and ir. you can mimic environmental, channel, and sensor configurations by modifying parameters of the sensor models. for active sensors, you can also model the corresponding emitters and channels as separate objects.

featured examples

scanning radar mode configuration

model different radar scan modes using the fusionradarsensor. this example shows how to configure the fusionradarsensor for several commonly used radar scan modes. with this model, you can simulate radars which mechanically scan, electronically scan, and which use both mechanical and electronic scanning. the scan limits in azimuth and elevation are configurable for both mechanical and electronic scan modes.

generate off-centered imu readings

generate inertial measurement unit (imu) readings from a sensor that is mounted on a ground vehicle. depending on the location of the sensor, the imu accelerations are different.
