rc_reason TagDetect Module

The rc_reason TagDetect Module enables any rc_visard to rapidly detect QR codes and AprilTags. This capability is highly useful for the reliable detection of objects, e.g. in pick-and-place applications.

  • Identification and localization of labelled objects
  • Reliable localization of a sensor in 3D space
  • Time-efficient: Detection time is less than one second
  • On-board data processing: No external hardware required
  • Out-of-the-box: Easy installation and operation

 

NOTE: The rc_reason TagDetect Module is included in the standard on-board software package for all rc_visards purchased 07/2020 and after. Please purchase this product only if you would like to upgrade an older rc_visard.

Registration and purchase approval required.

Description

The rc_reason TagDetect Module is an optional software component that can be easily activated on-board any rc_visard and operated through the sensor’s standard interface. It enables a robust detection of QR codes and AprilTags. In addition, it calculates the 3D position and orientation of each tag relative to the sensor.

The rc_reason TagDetect Module is a fundamental component for the efficient identification and manipulation of labelled objects, e.g. in pick-and-place applications. Further, it can significantly facilitate mobile applications as the rc_visard can localize itself in space using pre-installed QR codes or AprilTags as a reference.

A detection time of less than one second and the capability to detect multiple codes or tags in one shot make applications time-efficient.

NOTE: The rc_reason TagDetect Module is included in the standard on-board software package for all rc_visards purchased 07/2020 and after. Please purchase this product only if you would like to upgrade an older rc_visard.
