Data Structure Documentation

struct mavlink_optical_flow

Mavlink optical flow structure.

Using MAVLINK v1.0 generated code: Message ID 100 Fields are ordered to guarantee alignment

Definition at line 45 of file px4flow.h.

Data Fields
float flow_comp_m_x Flow in meters in x-sensor direction, angular-speed compensated [meters/sec].
float flow_comp_m_y Flow in meters in y-sensor direction, angular-speed compensated [meters/sec].
int16_t flow_x Flow in pixels in x-sensor direction.
int16_t flow_y Flow in pixels in y-sensor direction.
float ground_distance Ground distance in meters. Positive value: distance known. Negative value: Unknown distance.
