Hikrobot Machine Vision Software User Manual
Delay Time
The delay time should NOT be shorter than the maximum time required to transmit
the command across the network.
When the benchmark camera receives the command, all the cameras will trigger certain
actions simultaneously after the specified delay time.
5. Optional: Enable the Software system to send commands periodically.
1) Enable Periodically Send.
2) Enter the interval for sending the command.
Note
● If you enable Periodically Send, Request Acknowledge will be disabled, or vice versa.
● The default value is 1000ms, and valid value range is from 1ms to 3600000ms.
6. Optional: Enable Request Acknowledge to display the acknowledgment messages.
Note
● If you enable Request Acknowledge, Periodically Send will be disabled, or vice versa.
● Up to 50 messages can be displayed. Once the message number exceeds 50, the
earliest message will be automatically deleted.
7. Click Start Sending.
Example
Sample Use Case
To generate slow-motion playback in stadiums for the purpose of viewing and analyzing
the athlete's movement details, a group of camera is installed parallel to a race track (see
picture below).
When the athlete passes, four cameras (subgroup 1) synchronously execute an action
(capture images in this example).
As the athlete advances, the next four cameras (subgroup 2) synchronously capture
images. One after the other, the subgroups continue in this way until the athlete has
reached the end of the race track. The resulting images can be combined and processed
to generate the slow-motion playback in subsequent steps using other technology and
programs.
In this sample use case, the followings should be defined.
● Use the ActionDeviceKey parameter to authorize the execution of the synchronous
image acquisition. The device key should be configured on each camera and it should
be same with the device key for the action command protocol message.
● Use the ActionGroupKey parameter to define the group of cameras in a network
segment that is addressed by the action command (in this use case: group 1).
● Use the ActionGroupMask parameter to define the subgroups in the group of cameras
that capture images synchronously (in this use case: subgroups 1, 2, and 3).
