Access: In the Home screen, select Circular. In the Map view, tap ic_settings_green.png and select the Normal or Advanced tab. The Advanced tab give more flexibility and some options cannot be tweaked in the Normal tab.
OPTION DESCRIPTION

Drone speed

Defines the drone's speed from a range between Slow and Fast (default). The maximum speed depends on the selected overlap and flight altitude. The scale has five levels corresponding to percentages of the maximum speed between 100% (Fast) and 60% (Slow). The speed should fluctuate between 2 and 8 m/s for copters and is not constant during the flight since the drone slows down to trigger pictures.

 
Information: Reducing the speed might help to avoid capturing blurry images, but the Fast option is reliable for an optimal reconstruction with the software.

Angle between images (°)

Defines the angle that separates consecutive images. The smaller the angle, the higher the image overlap. The value varies between (Low) and 20° (High). The default value is 10° but if it was changed previously, the angle is the one of the last planned mission.

 
Important: The drone translates to always face the Point of Interest (POI) which is the center of the flight. The camera angle is set to focus on the ground. In other words, the camera angle is closer to vertical when the flight altitude is higher.

Picture trigger mode

- Except DJI drones

Defines how pictures are triggered between stopping to shoot, Safe mode, or while the drone is flying, Fast mode (default).

 
Information: The Safe mode significantly increases the flight time. The Fast mode requires good connection with the drone as the trigger relies on a signal.

White balance
Advanced

- Except Bebop 2

Defines the white balance to apply between Auto (default), Sunny and Cloudy.

 
Information: It allows to compensate temperatures so that the color of the image is as close as possible to neutral which corresponds to sunlight at noon outdoor. For each image the temperature is adjusted by an algorithm that optimizes the colors.

Ignore homepoint
Advanced

Defines whether the maximum authorized distance (2 km) between the home point and the flight plan is applied, No (default), or ignored, Yes, to start the mission.

 
Important: The home point is the location where the drone is turned on and acquires the GPS signal the first time. This distance is mainly for security reasons, to prevent an accidental launch of a mission when the grid is too far away and it is also limited to prevent connectivity losses.


The Reset all settings button makes all options revert to their default values.

    Hi,

    In the current version of Pix4D Capture the POI is ALWAYS on the ground.  The lack of the ability to set the POI at a higher altitude makes is impossible to, for instance, capture to bottom of a water tower inside the legs.  All I get is a shadow underneath, no detail.

    I have had no luck using other caputure apps to get the bottom of the tank detail.  Free flight at the level of the bottom of the tank is dangerous as the bird is out of site behind tower much of the time.

    I have tried to add other photos from automatic and manual circular missions in other apps and cannot get the non-Pix4DCapture images to blend in with those taken with Pix4D IOS.  I get multiple images of the tower when I try.  Manual Tie Points don't help.  I still get multiple images in the same model, mostly off vertically but some horizontally as well.

    It seems different capture apps report the GPS position somewhat differently than Pix4DCapture.  I am waiting now for processing by un-calibrating the cameras used by the non-Pix4DCapture.  I have tried DJIGo, DJI Ground Control Pro, and Litchi to mix with Pix4DCapture images, all un-succesfully.

    I do understand that the sky becomes an issue for Pix4D capture if the gimbal is pointing up toward the horizon, especially when there a puffy clouds.  I have done the 'bottom of the water tower tank' circle missions near mid-day on clear sky days.

    So I have two issues.  One is a request to be able to adjust gimbal angle and/or the POI height above ground for circle missions.  Two is to figure out how to work around the lack of POI height adjustment in Pix4DCapture by blending in images from other apps.

    Thanx for any advise.
