Problems solved by technology

[0002] The currently known point-packing method is to use infrared transceiver probes, place them on one side or both sides of the conveyor belt, and calculate the number of bags passing the probes by calculating the number of bags passing the probe or the time it takes for the bags to pass the probe. , this technology is easy to cause measurement errors in the case of stacked bags, continuous bags, blocked bags, slippery bags, flying bags, and unstable conveyor belt speeds. There are also visual technologies used to measure packaged items on the conveyor belt. However, for The packaging bags in bagged form, the above-mentioned problems are still not well resolved

Embodiment Construction

[0014] The present invention will be further described below by five examples, but following examples are not intended to limit the present invention, all adopt similar method, structure and similar changes thereof of the present invention, all should be included in protection domain of the present invention.

[0015] The visual type point package method of the first embodiment, the steps are as follows:

[0016] 1. Install the camera above the conveyor belt to collect video information of the packaging bag movement.

[0017] 2. Install a light source above the conveyor belt to provide uniform lighting to ensure that better quality packaging bag video information can be collected.

[0018] 3. Install a small hair dryer near the camera mirror to prevent dust from affecting video capture.

[0019] 4. Send the conveyor belt running signal to a computer composed of a DSP embedded single-chip microcomputer or a computer. When starting the conveyor belt to run, start the applicatio...

Abstract

The invention discloses a visual packaging bag counting method, and relates to metering of packaging bags on a conveyer belt and aims to overcome metering errors caused by overlapped, connected, blocked, slippery and flying packaging bags and unstable speed of the conveyer belt. The method comprises the following steps: collecting video signals of movement of the packaging bags on the conveyer belt by a camera; then, tracking the movement tracks of the packaging bags and movement abnormalities of the packaging bags by using an image analyzing method; and adopting other packaging bag counting methods such as an infrared sensor. The methods are verified by each other and corrected by each other. The video records the packaging bag counting process, and labels for the packaging bags with abnormal movements such as overlapped, connected, blocked, slippery and flying packaging bags are placed and transferred to the network so as to realize the live video and user on-demand functions. The user can check the packaging bag counting process of a certain batch and quickly position and check the packaging bags according to the labels. According to the method disclosed by the invention, the long-standing problem that the packaging bag counting precision is affected by overlapped, connected, blocked, slippery and flying packaging bags is solved, and the image analyzing burden can be alleviated.

Description

technical field [0001] The invention relates to a measurement technology for packaging bags on a conveyor belt, in particular to a visual method for counting bags. Background technique [0002] The currently known point-packing method is to use infrared transceiver probes, place them on one side or both sides of the conveyor belt, and calculate the number of bags passing the probes by calculating the number of bags passing the probe or the time it takes for the bags to pass the probe. , this technology is easy to cause measurement errors in the case of stacked bags, continuous bags, blocked bags, slippery bags, flying bags, and unstable conveyor belt speeds. There are also visual technologies used to measure packaged items on the conveyor belt. However, for For the packaging bag in bagged form, the problems referred to above are still not well resolved. Contents of the invention [0003] Aiming at the defects in the above-mentioned prior art, the technical problem to be s...
