Harle2D|3D. The power of a combined controls system to improve the quality of production.

Harle2D|3D vision inspection system combines a traditional 2D vision inspection with a 3D control to ensure 100% control of the oral solids inspected on the feeding unit of counting machines, blister thermoformers or strip packaging machines before the packaging.

While Harle2D performs a traditional check of the oral solid (mainly size, shape and colour), Harle3D analyses height information to control the product thickness: in this way it is possible to find defects that would otherwise be invisible for a standard bidimensional vision system.

The vision system tracks every product in movement on the feeding channels and allows single wrong product rejection, preventing the outflow of defecting products and avoiding the rejection of the entire packaging with important benefits in terms of quality and savings.

Harle2D can be standalone installed. Harle3D can be installed only in combination with Harle2D.

One solution combining 2D|3D controls

Production quality improved

Avoid the outflow of defective products

Inline efficient inspection

Single product rejection management


The third dimension of vision inspection

Developed with powerful proprietary algorithms, Harle2D|3D is designed to check 100% of oral solid dose products on filling & counting, blister thermoforming or strip packaging machines.

The 2D controls allows to check the traditional pictorial and geometric parameters of products, such as shape, size, color and presence of major defects of all tablets or capsules before the end of the feeding channel. The bi-dimensional check allows to control the products find all the defects on the top visible surface of the object.

The 3D technology completes the inspection, allowing to capture the whole product images, without blind spots: using a LED pattern projection method, Harle3D can control each product in its entirety, allowing the identification of defects as happens for decapped tablets.

The HMI display shows in real-time the results of every product checked and, while 100% of products units are inspected, the vision inspection system manages the rejection of each non-compliant items.

The vision system can be installed on any filling and counting, blister or strip packaging machine currently available on the market, perfectly integrating itself thanks to its automation logic – thus without impact on the production speed.

Specifically designed for the pharmaceutical field, the system is entirely compliant with all industry regulations.


Oral solid dosage forms

100% complete inspection

Accurate control and tracking on oral solid product, down to single reject

Harle2D | 3D inspects 100% of the production and can detect all possible defects on solid products, thanks to the wide range of controls it offers. From the correctness and integrity of the single product, all controls are customizable and can be carried out individually or in simultaneous combinations.

The vision system is designed to detect even the minimal difference in term of size, shape, and color.

The system guarantees the identification and control of the products even if durind their path in the vibrating channels they assume different positions under the cameras or they are very close or touch each other.

2D controls on tablets

  • Dimension
  • Colour
  • Shape
  • Integrity (broken or chipped tablet)
  • Coating defects

2D controls on capsules

  • Dimension
  • Colour (monochromatic and two-color capsule);
  • Shape (excessively closed capsule, excessively open capsule)
  • Integrity (open capsule, half capsule).

3D controls on tablets and capsules

  • Product height control
  • Decapped tablet identification
  • Crushed capsule identification
Flexible controls

Inspected products

There is no oral solid product that harle2D|3D cannot control. The result is always optimal.

Harle2D|3D can control all solid and oral products:

  • White and coloured tablets
  • Coated and uncoated tablets
  • Capsules – monochromatic
  • Capsules – bicolored

Designed to boost performances

Harle2D|3D makes use of cameras for the images acquisition and processing. The values measured for each object are compared with reference models and, if one of them is outside the tolerance range, the system automatically send a signal to the machine, allowing the rejection of the defective blister.

An accurate inspection is granted, in just milliseconds.

Such rapid elaboration times are possible thanks to Harle2D|3D system’s SIMD instructions developed in-house, and smart proprietary algorithms (designed upon the concepts of spatial and temporal parallelism) programmed to make the most of all the threads available in the latest generation CPUs.

Since threads divide the core of a CPU into many virtual multiple cores, the usage of all of them allow a computer processor to perform multiple tasks at the same time, and faster.

The result is that the algorithms of Harle2D|3D are able to improve theirself software computing power; reducing the images processing times, while performing more controls, and guaranteeing at the same time the best results in terms of inspection accuracy and safety.

Hardware features

The importance of a good hardware

The system is provided with latest genereation industrial computers including a multicore technology and multithreaded processors, in order to take full advantage in term of elaboration speed and accuracy.

Optics and light units components are specifically designed and assembled for an optimal inspection, and for a perfect integration with the machines mechanical design. With an optimized lighting management, the images acquisition speed is fast and accurate.

The touch-screen displays provided have optimized graphic interface that increases usability and interaction.


Security and compliance

The system is specifically designed for the pharmaceutical market, and it is compliant with the industry regulations, with user access regulated by FDA 21 CFR part 11 and annex 11.

All events are registered by the software in an audit trail file to keep track of all the security-relevant activities.

The continuous Software development follows Gamp 5, to always improve products quality and consistency.

Integration with machines

The result of a broad experience of vision systems integration

SEA Vision’s expertise in integration is built on decades of experience working alongside machine manufacturers to satisfy the needs of pharmaceutical customers worldwide.

Such experience guarantees correct machine integration, accurate signal exchange management, and integrated automation and rejection logic.

Harle2D|3D can be integrated on machines with different automation levels, from entirely automated or semi-automated to modules with a low automation level.

The graphical oscilloscope allows the observation of signal patterns and keeps them under control, facilitating the diagnostical operation.

The entire process is handled efficiently, from the control execution to the rejection of defective products.

A reliable and future-proof solution

Native integration with yudoo

Harle2D|3D is natively integrated with Yudoo, the 4.0 pharmaceutical software suite for the full management of automation processes, digital quality, data analysis and for Track&Trace. A digital hub that is everywhere accessible through a secure-access web interface or dedicated devices.

A scalable and modular suite, including tools for automation (centralized management of production, workflows and timesheet), for the digital quality (creation of paperless systems, support systems for line clearance operations), for data analysis (analysis of production data, business intelligence dashboard, condition monitoring and predictive maintenance) and for Track and Trace (complete solutions for Level 3 and 4 of serialization, monitoring of serialization operations).

Yudoo offers multiple advantages such as the possibility to centralize production formats and data, avoiding duplicates and reducing work time. The suite can connect to existing company systems to retrieve updated data exactly from where they are.
