摘要: A method comprising: digitally processing orientation measurements provided by each of first and second inertial measurement units, the first and second units being arranged on first and second body members of a person, respectively, according to a predetermined unit arrangement, and the first and second body members being connected by a joint; the measurements are digitally processed such that the computing device at least: computes a length vector of a segment of the first body member based on a first orientation measurement of the first unit; defines a joint axis plane of the joint based on a second orientation measurement of the second unit; and computes a heading rotation value for making the first orientation measurement to be contained within the joint axis plane defined; and the method further comprising digitally modifying the first orientation measurement or the second orientation measurement by applying a rotation at least based on the heading rotation value computed. Also, a motion tracking system and a computer program product.

摘要: An approach is provided for predicting a pose error for a sensor system based on a trained machine learning model. The approach, for example, involves receiving images depicting a survey point with a known physical location. The approach also involves determining meta-data associated with the sensor system used to capture the images. The approach further involves generating a ray from the capture location through a pixel location of the survey point on an image plane of each image. The approach further involves calculating an error between the ray generated for the image and the known physical location. The approach further involves training a machine learning model to predict a pose error from image data captured using the sensor system based on the error in combination with features extracted from the image and the meta-data for the image. The approach further involves providing the trained machined learning as an output.

摘要: Die Erfindung betrifft ein System zum Überprüfen einer inertialen Messeinheit (IMU) eines Fahrzeugs (V), insbesondere eines Landfahrzeugs, während der Fahrt, wobei die inertiale Messeinheit (IMU) einen ersten Beschleunigungssensor zum Messen einer translatorischen Beschleunigung entlang einer ersten Sensorachse und / oder einen ersten Drehratensensor zum Messen einer Drehrate um die erste Sensorachse aufweist sowie einen zweiten Beschleunigungssensor zum Messen einer translatorischen Beschleunigung entlang einer zweiten Sensorachse und / oder einen zweiten Drehratensensor zum Messen einer Drehrate um die zweite Sensorachse aufweist, wobei eine Erfassungseinrichtung zum Erfassen einer Bewegung des Fahrzeugs (V) in einer ersten Fahrzeugrichtung und / oder um die erste Fahrzeugrichtung ausgebildet ist, dadurch gekennzeichnet, dass sowohl die erste als auch die zweite Sensorachse gegenüber der ersten Fahrzeugrichtung verkippt ist.
