Object Detection

CA Patent# 2814294, February 2021/ US Patent# 10373470, August 2019

An object detection apparatus comprising a camera having video output comprising frames; and a digital video processor configured to receive the video output from the camera, detect and track a blob in the frames to determine a trajectory for the blob and trigger an alert message if the trajectory of the blob is characteristic of an object to be detected. The digital video processor may detect and classify the object as a leak, and provide an alert or alarm.

Leak Detection

US Patent# 10234354, March 2019

Apparatus and corresponding method are invented for detecting a leak in equipment forming a target, such as a stuffing box. The apparatus includes an image analyzer configured to receive an image from camera and analyze the image to determine if a leak on the equipment is present by comparing a color channel of the image with a reference and the image analyzer having an output port for delivering a notification upon the image analyzer determining that a leak is present on the equipment.
