@James-Strawson yes,we only test uav in position mode. we didn't use manual for testing.

pls help me soon. we can set up an online support via teamview to make the problem more clearly.

last week it used to work normally. i did't changed any strange thing, just re-configuration the drone to the factory state. by "voxl-configure-vision-px4 -f" to take again the NED position cuz before that i had config vision lib by "voxl-configure-modalai-vl" and the local poistion is lost.

the local NED position is look good at the init state as well as when i move the drone into the other location.

hi, here is the video i just captured https://drive.google.com/file/d/1Am63zD09am8nx_BBpAB2JfTYcf_IFMST/view?usp=sharing

it just is a whitle floor like this

Hello, me again my voxl m500 frame is driff while fly in position mode

here is the voxl/vision-px4.conf text. last time after reset the configuration to the factory -> then i also changed the offboard mode to "off" and the m500 can fly in poistion mode but the performance is not good, it's mean sometime the the driff was maintained. i think the problem is not here. (about reset the vision-config to the factory, i just reset and not config anything...
pls help me!

@Chad-Sweet oh my godness. My mistaken, i didn't realise that before that i had configured UAV off board mode. when I check the /etc/modalai/voxl-vision-px4.conf the offboard_mode ="figure_eight" => so that's why it's cause the problem here. anyway, it's work again, thank you so much for the effective support

Here is the video of flight with position mode, what is the problem ???
video link

every step is correct with the manual document. Here is what we do with the UAV. In the last week i had tested the UAV load in position mode and it's work well, after that i also tried with MavROS node to take-off UAV in Offboard mode. we would set the altitude to take off is 0.5 m but the UAV takeoff higher than 1m much (i had build rosnode after launch).
But it was other problem, in this week we had installed a asus xtion camera and a raspberry pi at the bottom of m500 frame, then trying to maunally filght at position mode but the driff has occurred.

@modaltb hi, i'm just trying to take-off manually though RC in position mode.

Hello, as the topic name when I starting to fly indoor nav with M500 VOXL frame, the UAV not go up straight but driff to the left side or right side (randomly). I also checking the Local_position_NED is 0,0,0 before the flight.
Here is the "systemctl status voxl-vision-px4"

and when i test the odometry with "voxl-test-vision-lib -o"

pls give me some advice.

Problem Solved. for anyone in the future have similar case just perform factory configuration for VOXL Flight Deck by
"voxl-configure-vision-px4 -f" and then re-connect to QGC and you will see the miracle.

@Vũ-Văn-Long and after i run command check the status

@James-Strawson said in Help! lossing data from camera + IMU tracking:

voxl-test-vision-lib -o

hello, i was ran that command and it's have an error.

Hello, im working with m500 drone. when i starting with ROS, i was calibration camera here. after that m500 cannot display the value of x,y in NED position in QGC (just remain Z value). after reading document i think the SNAV was reset after i ran config command. it's right?
Then the solution is recalib the Modalai Visio Lib at here? but what is the selection for IMU and tracking camera? Please confirm if i miss anything.

@Chad-Sweet hi. i am reading mavros document now. Thank for your guide.

Hello modalai team, i'm a customer of voxlm500 products and currently i want to uss voxl m500 with ROS. My goal is publish all the parameter which is the local position NED of drone into ROS and i can subscriber those params on mine PC. But i don't know how to take those params from? can you help me?

hello development, i am a user of VOXL_m500 product and i'm trying to setup a first flight with deinided-GPS navigation feature. by default px4 will detect the location of UAV base on GPS, so in the case of m500 uav the operation environment will be indoor space. i know that it use odometry data frome the optical sensor to check uav location in space. i have a question that is how the px4 is accepted odometry data (or please give me some source code, i just want to ensure that the uav used odometry data instead the location from GPS. thank you so much !
