Method and apparatus for deriving novel sports statistics from real time tracking of sporting events

A method and apparatus for deriving performance statistics from real time tracking of a sporting event. The method according to the present invention includes a step of obtaining a spatio-temporal trajectory corresponding to the motion of an athlete and based on real time tracking of the athlete. The trajectory is then broken down so that performance information corresponding to the motion of the athlete (such as speed, distance covered, acceleration, etc.) can be derived with respect to time. The information so obtained can be stored in a database or the like for later retrieval or can be used to graphically supplement a video broadcast of a sporting event. The apparatus includes a device for obtaining the trajectory, a computational device for obtaining the performance information based on the obtained trajectory, and a statistical device for compiling the performance information. In particular, the spatio-temporal trajectory may be obtained by an operation on a video image of the sporting event, in which motion regions in the image are identified, and feature points on the regions are tracked as they move, thereby defining feature paths. The feature paths, in turn, are associated in clusters, which clusters generally correspond to the motion of some portion of the athlete (e.g., arms, legs, etc.). The collective plurality of clusters corresponds with the motion of the athlete as a whole.

Remote damage assessment method and system based on distributed artificial intelligent image recognition

The invention discloses a remote damage assessment method and system based on distributed artificial intelligent image recognition. The method comprises the steps that an image collecting device collects external part images of a traffic accident vehicle and sends the external part images to a cloud platform; a vehicle-mounted sensor device acquires collision data information and uploads the collision data information to the cloud platform; an image processing module carries out preprocessing on the collected external part images of the traffic accident vehicle and stores the image preprocessing results into a vehicle damage assessment database; an image feature extraction module extracts features of the external part images according to the image preprocessing results, image matching is carried out on the obtained preprocessing external part image feature information of the traffic accident vehicle and an image base in the vehicle damage assessment database, and an external part damage assessment result of the traffic accident vehicle is obtained through a vehicle external part damage assessment model. By means of the method, on one hand, traffic accident vehicle external part damage assessment can be quickly carried out; on the other hand, by means of image and collision information step-by-step type damage assessment, the damage assessment faults can be reduced, and the precision and efficiency of settlement of claims can be improved.

Method for video matching in video template library

The invention discloses a method for video matching in a video template library. A video template and an index of all feature codes corresponding to appearance positions of the feature codes in the video template are stored in the video template library, wherein the video template is obtained by connecting the feature codes of key frames in a time sequence. The method includes the steps that a query video is segmented, the key frames are selected from all query video segments, and the feature codes are extracted from all the key frames; the feature codes of all the key frames of all the query video segments are extracted, and the video template where the feature codes appear is searched for according to the index of the feature codes in the video template library; video template segments corresponding to the query video segments are found out in the video template according to the positions of the key frames in the query video segments, and whether the query video segments and the video template segments have a matching relation is judged through comparison based on the feature codes; the corresponding appearance position of the video template in the query video is obtained according to the matching relation between the query video segments and the video template segments. The method for video matching in the video template library improves video matching speed and robustness.

Monitoring video file restoring method

The invention provides a monitoring video file restoring method, which comprises the step of writing video file header information and also comprises the steps that the current video file is set to be in a writing state; video frame data is written into a media data object block, and media index information is periodically stored into a memory; after the writing of the video frame data is completed, the media index information is written into the video file tail, and in addition, the video file is set to be in a writing completion state; during video frame data abnormal writing interruption, video breakpoint information is recorded into a video breakpoint memory vault, and the current video file is set to be in a writing incompletion state; when video monitoring equipment is booted, if the existence of the video file in the writing incompletion state is detected, the video breakpoint information is read, the media index information of the video file is written into the breakpoint part of the video file, and the video file is set to be in the writing completion state. The monitoring video file restoring method has the advantages that after the power failure in the video recording process, the damaged video file is restored, and is recovered to the video several seconds earlier before the power failure, and the completeness of the video is ensured.
