OCR spreader based crane to Estonia

2016-06-07

Finland’s Visy Oy has been awarded a contract for a crane spreader-based OCR system, some think this location is too challenging for OCR equipment.

Visy has been awarded a contract to supply Transiidikeskuse (TK) in Estonia with “TopView”, the new OCR system for container handling.

TopView is installed on the crane or mobile equipment spreader. This is something that other OCR system suppliers didn’t came close to, on the grounds that spreaders are subject to very high shock loads, and are an interchangeable component. However, if these issues can be solved by visy, locating cameras on the spreader avoids the complication of trying to design a camera system to follow the variable load path of a spreader and capture its container number with equipment mounted on the crane structure itself. 
T
opView, according to themself, uses “multiple highly robust cameras attached to spreaders that point towards the container during the whole lifting and dropping operations. The cameras capture high-resolution images which are being used for container code identification with the use of optical character recognition (OCR) and damage inspection. TopView works in conjunction with Visy's Gate Operating System (GOS) and OCR application to automate terminal processes. The system accommodates cranes operating with single, twin, tandem and quad spreaders.”
“We’re pleased to be the first company to offer a spreader OCR solution to the terminal market,” said Petri Granroth, Visy's General Manager. “TopView significantly simplifies crane OCR applications and provides operators with damage inspection images of the top of containers without adding steps to terminal processes. We believe that Top View will revolutionize CHE OCR applications the terminals.”
In an STS crane OCR application, TopView can used either as a standalone system, to capture images of the two container codes on the roof of an ISO container, or combined with other cameras for more images. With cameras also located on the boom and in the backreach, the container code can be captured from four different locations on single and twin operations and three locations on tandem and quad operations. “The result is that the OCR hit rates will be as high as systems with three times as many cameras, thus significantly reducing the cost of ownership of such a high-performing system,” VISY added.
