Group activity data collection method and system based on multisource space-time trajectory data

The invention discloses a group activity data collection method and system based on multisource space-time trajectory data. The method comprises the steps that a background obtains and preprocesses original mobile terminal signal data and original social software signature data and generates to-be-processed signal data and to-be-processed signature data in consistent with specific formats; the background obtains activity point trajectory data from the to-be-processed signal data, establishes and learns prior information of group activity rules, obtains activity point trajectory data, and obtains activity location data; the background marks activity point trajectory semantic information by employing a Bayesian model and generates an activity space-time trajectory chain according to the activity point trajectory data, the prior information of group activity rules and the activity location data. According to the method and the system, individual activities are deduced by employing the Bayesian model; the influence of the activity type of a former moment on the activity type of a latter moment in the space-time activity trajectory is taken into consideration; and accurate, fast and efficient extraction and collection of wide-range and massive group activities are realized.

Travel navigation method meeting activity needs and path optimization

The invention relates to a travel navigation method meeting activity needs and path optimization, which comprises the following steps of: building initial activity schedules and listing specific activities, activity place limiting conditions and time constraint conditions of the travel by common individual travelers according to practical individual travel requirements; finding activity places capable of meeting the activity requirement of travelers by combing the intraday activity and place limiting conditions, extracting alternative activity place from the activity places for congregation; and determining the number of fixed point activity pairs, obtaining the optimal place in each fixed point activity pair by combining the time constraint condition and utilizing the heuristic search algorithm, using the optimal places as unfixed point activity places, simultaneously obtaining the optimal travel path of each activity pair in each fixed activity pair, and determining all intraday activity places and travel paths of the travelers. A geographical information system (GIS) is utilized as a technology platform, and the individual traveler is navigated according to the optimal activity places and the travel paths obtained in the step 3.

Lighting systems and methods providing active glare control

A light fixture includes a dimmable light source that emits light downwardly, and a downward-looking rangefinder proximate and operatively coupled with the light source. When the rangefinder detects an object at a measured height that exceeds a first threshold, the light source dims according to the measured height. A light fixture that provides illumination with active glare control for a lighted area includes one or more first light sources that emit high-angle light, and one or more dimmable second light sources that emit low-angle light, into the lighted area. The system also includes a camera that captures images of the lighted area, and a controller that is (a) operable to identify one or more activity locations within the lighted area from the images, and (b) operatively coupled to dim one or more of the light sources that illuminate the one or more activity locations.

The invention relates to a method and apparatus for determining an object foothold, and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: obtaining activity information of a target object collected by a first camera, wherein the activity information comprises a unique identifier of a media access control address device of a device used bythe target object, an activity time of the target object and an activity location of the target object, and the first camera has a function of detecting the unique identifier of the device; determining the activity time length of the unique identifier of the device at each activity location according to the activity information; and determining the foothold of the target object according to the activity time length and the corresponding activity location. The problem that the target object deliberately avoids the camera, such that the foothold of the target object cannot be determined, can besolved; and since the camera can detect the unique identifier of the device used by the target object, the foothold of the target object can be determined according to the occurrence time and locationof the unique identifier of the device, and the difficulty of detecting a case is reduced.
