![]() ![]() ![]() The Full HD 60 frames-per-second version DR770X-2CH LTE will also be released, replacing the existing DR750X-2CH LTE Plus models, and available in versions with regular rear camera, interior infrared camera or external waterproof rear camera. With this model, customers won’t have to choose between image quality and Cloud capability, as the DR970X-2CH LTE offers the best of both worlds in a compact package. ![]() Accounting for all variants, BlackVue is introducing no less than fourteen new models this year.Ĭhief among them is the much anticipated DR970X-2CH LTE, a dual-channel dash cam with 4K UHD recording and built-in LTE connectivity. All the soon-to-be-released models will be on display at BlackVue’s booth #7251 in the West Hall of the Las Vegas Convention Center, from January 5 to 8. SEONGNAM, GYEONGGI-DO, SOUTH KOREA, - JanuBlackVue Dash Cameras is excited to introduce its upcoming lineup at the 2023 Consumer Electronics Show (CES) in Las Vegas. (Optional) batch crop images to remove OSD info and/or side reflections.Highlights Include New 4K UHD Camera With Built-In LTE Connectivity And Secure “Box” Model With Three Cameras And Separate Recording Unit.do the batch processing using ts_processor with desired parameters set.In general with this script the workflow is very much straightforward and time-efficient: I will prepare and upload some test sequences later next week so those of you who are interested could have a look. Interpolation inside the tunnels works fine (obviously resulting in interpolated coordinates distributed along straight line) and you can control this behavior with -min_coverage parameter. 2-5 frames per second (sampling interval 0.5-0.2 sec) is working fine and gps coordinates are accurately interpolated. Thanks to interpolation support, you can obviously do the sampling at a higher fps, i.e. With timeshift parameter you could make an adjustment.Īfter extensive testing on both B4K and A119V3 footage I can say that 0.5 appears to be the optimal value under most conditions and will be giving you a precise positioning of your sampled data. I have observed that gps coordinates recorded inside the video stream are a little bit late (out-of-sync), which means that gps position on the map is a little behind the actual sampled image location. TS) may work as well (not tested)įrom my testing I can say that most common an optimal config would be:ġst is basically tells to extract 1 image per secondĢnd is very important one. It is confirmed working with Viofo A119 V3 and Blueskysea B4K produced files, but some other Novatek 966x based models (supporting. TS files are supported, there is no support for. You could check all default parameters applied inside the script Python ts_processor.py -input 'filename_or_folder' Does GPS metadata stored somewhere in the external files apart from TS video itself on B4K?Ģ. I really want to spend some effort on promoting B4K among Mapillary contributors community as it seems to be excellent alternative to DR900S (4 times cheaper!)Īnd couple of additional questions to the owners (while I am waiting for delivery):ġ. I can see that metadata is there (using GPS player from Blueskysea and DVplayer has also added B4K support, can you help here? Maybe someone has some specs on how/where GPS metadata is stored in B4K TS files? (I have used raw file from this post, thanks ) I have already contacted Phil Harvey (Exiftool author) and Mapillary devs, but they were not able to quickly find the trace of GPS metadata within B4K TS sample files. I am doing it like this for DR650S with external GPS logger, while built-in one was not reliable.īut having in mind that B4K stores GPS metadata within the file (similar to GoPros and BV DR900S), I am keen to optimize and automate workflow with mapillary tools by adding support for B4K. 1 frame per second, or 1 frame per 2 seconds), extract the metadata and geotag resulting sequences preparing them for upload.Īll other dashcams/action cams require additional steps: sample video in frames, get the GPS log from external app/file, synchronie the two and geotag resulting sequences. It can sample video clips to individual frames (images) at a given rate (i.e. Mapillary tools (open-source command-line tool developed and supported by Mapillary and community) provides native support for GoPro family actioncams and Blackvue DR900S dashcams. I am an active Mapillary and Openstreetcam contributor and I would like to optimize my workflows to sample and process (geotag) imagery from B4K. I have ordered a sample and looking forward to use it as a replacement for my Blackvue DR650S with Mapillary and Openstretcam ![]()
