Abstract

A control method based on computer vision is disclosed, the method includes: photographing multiple sample bottles on a tray in a top-view manner to generate a top-view image; performing an object detection process on the top-view image to identify a type of a label on a cap of each sample bottle and a placement position of each sample bottle in a chamber; dividing the multiple sample bottles into multiple groups based on the respective types of the multiple labels, and sorting the multiple groups to generate a sampling order; controlling an actuator to drive a detector bar on a lifting arm in the actuator to sequentially collect samples in the multiple groups based on the sampling order and the multiple placement positions.

Dependent claims

A control method based on computer vision for a detection device comprising a chamber, a tray, and an actuator, wherein the control method comprises:

by a camera circuit disposed above the tray, photographing a plurality of sample bottles on the tray to generate a top-view image;
by a processor, performing an object detection process on the top-view image to identify a type of a label on a cap of each of the sample bottles and a center point of a label object corresponding to each of the labels in the top-view image, and converting a position of each of the center points in the top-view image into a placement position of each of the sample bottles in the chamber;
by the processor, dividing the plurality of sample bottles into a plurality of groups based on respective type of the plurality of labels, and sorting the plurality of groups to generate a sampling order, wherein the plurality of groups respectively correspond to different testing manners and different sample types;
and
by the processor, controlling the actuator to drive a detector bar on a lift arm in the actuator to sequentially collect samples in the sample bottles comprised in each of the plurality of groups based on the sampling order and the plurality of placement positions.
