This disclosure provides a moving object tracking method and apparatus. The method includes: obtaining a current frame captured by a camera; predicting a current state vector of the camera based on an inertial measurement unit IMU and the current frame, to obtain a predicted value of the current state vector of the camera; predicting a current state vector of a target object that is moving in the current frame, to obtain a predicted value of the current state vector of the target object; and updating a Kalman state vector based on a measurement result of an image feature in the current frame. According to technical solutions provided in this disclosure, a target object that is moving in a surrounding environment can be tracked and a pose of the target object can be estimated while a pose of a system can be estimated.

Moving object tracking method and apparatus

The method includes: determining a reference sensor from at least two sensors and sampling moments of the reference sensor; when obtaining observation data of a sensor K at a moment t, determining a type of the sensor K; if the sensor K is a first sensor of a first type, determining a sampling moment Tthat is closest to tand an interpolation coefficient &#x3bb;, and calculating first rotation data and first translation data that are at T, and a first covariance matrix; if the sensor K is a second sensor of a second type, determining two sampling moments Tand Tthat are closest to tand interpolation coefficients &#x3bb;and &#x3bb;, and calculating second rotation data and second translation data that are of the second sensor from Tto T, and a second covariance matrix; merging rotation data, translation data, and covariance matrices that are at the sampling moments.

Sensor data processing method and apparatus

A tablet cover comprising a top cover having a top cover hinge mounted on a side edge of the top cover; a bottom cover having a bottom cover hinge mounted on an outside surface of the bottom cover; and an extension arm swivel connected to the bottom cover at the bottom cover hinge. The length of the extension arm is approximately half of a width of the tablet cover. The intermediate hinge arm is swivel connected to the extension arm at an intermediate hinge and the intermediate hinge arm is swivel connected to the top cover at the top cover hinge. A length of the intermediate hinge arm is approximately a thickness of the tablet cover. The tablet cover has an open position, a stand position and a closed position.

A system for in line in situ validation of an air filter of an exhaust filter system including a scan head, a means for facilitating movement of said scan head in the XY plane, a means for externally controlling the movement of the scan head from outside the plenum of the exhaust filter system in the XY plane, and a means for coupling the scan head to the means for externally controlling the movement of the scan head, is provided. The system can also include a scanning arm, inside and outside magnetic couples, and rolling means to facilitate movement of the inside and outside magnetic couples. A method for in line in situ validation of an air filter in an exhaust filter system is also described, which involves the use of the system for in line in situ validation of air filters of an exhaust filter system.
