Obstacle avoidance / Collision prevention is disable in QGroundControl

shlee853

Hi guys,

I'm testing flight deck and I'm trying to test object avoidance and collision prevention.

as you know flight deck sensors, I have hi-resolution camera, stereo vision and tracking camera with default configuration.

this is my voxl-vision-px4.conf

{
"qgc_ip": "192.168.219.182",
"en_localhost_mavlink_udp": true,
"en_secondary_qgc": false,
"secondary_qgc_ip": "192.168.1.214",

"en_voa": true,

"en_send_voa_to_qgc": false,

"adsb_uart_baudrate": 57600,
"px4_uart_bus": 5,
"px4_uart_baudrate": 921600,
"offboard_mode": "figure_eight",

"R_imu_to_body":    [[0, 1, 0], [1, 0, 0], [0, 0, -1]],
"T_imu_wrt_body":   [0.068, -0.015, -0.008],
"height_body_above_ground_m": 0.05,
"T_stereo_wrt_body":    [0.10, -0.04, 0.0],
"land_on_tag_id":   0,
"follow_tag_id":    0,
"en_apriltag_fixed_frame":  false,
"fixed_apriltags":  [{
    "tag_id":   0,
    "R_tag_to_fixed":   [[0, -1, 0], [1, 0, 0], [0, 0, 1]],
    "T_tag_wrt_fixed":  [0, 0, 0]
    }],
"en_transform_mavlink_pos_setpoints_from_fixed_frame":  true,
"en_fixed_frame_pipe": false,
"fixed_frame_filter_len": 5

}

I already calibrated my stereo vision camera and I found calibration result as below.

before calibration

after calibration

yocto:/# ls /home/root/.ros/camera_info/
left.yaml right.yaml tracking.yaml

yocto:/# ls /etc/snav/
calibration.stereo.xml

but, when I try to debug stereo mode with voxl-vision-px4, it stop on this.
I think it's not normal. It sound display cloud point on terminal.
am I right?

}

also, when I connect to QGroundControl, I cannot satisfy pre-arm check because of avoidance/collision prevention Disabled

also, I alredy checked all the relative parameters as like this.

Could you please give me advise to test obstacle avoidance?

Thanks,

Chad Sweet

If you start voxl-vision-px4 manually, you can run 'voxl-vision-px4 --help' and see the following option available

-s, --debug_stereo print detected stereo obstacles as linescan points

shlee853

@Chad-Sweet as you can see above script, I already run manual option -s.

But, I cannot see any obstacle cloud point. Just stop on processing.

Please look at above message carefully.

Thanks,

@Chad-Sweet Hi Chad,

Could you please let me know the example of normal operation with -s option?

Thanks,

James Strawson

@shlee853

I'm afraid to say the VOA feature has not yet been ported forward to our new software architecture (voxl-suite v0.3.4), but it still works in the legacy software (voxl-suite 0.2.0). We are a few weeks away from finishing the new version of VOA and adding it back in, at which point we will release another voxl-suite version. Until then you can go back to voxl-suite 0.2.0, sorry for the inconvenience! We are in a bit of a transition period as we rewrite all of our legacy software in the new architecture.

Best Regards,
James

@James-Strawson got it.

My test s/w version is volx-vision-px4 0.3.4 and has a same problem, am I right?

Okay, I’ll proceed test VOA using 0.2.0 version before releasing new version s/w.

Can I know release date for new version?

Thanks,
