Analyze camera images with AI! What is IVA (Intelligent Video Analytics)?

AI(artificial intelligence) has evolved rapidly, and AI has come to be used in various situations that we encounter in our daily lives. The learning ability of AI has improved dramatically, and human behavior analysis, attribute analysis, and authentication using image data from cameras, such as suspicious person detection, unmanned store management systems, and congestion mitigation, are now evolving. .

 

 本記事では、「画像解析」に焦点を当てて、解決出来る課題や導入例についてご紹介します。

What is IVA?

IVAis an abbreviation for "Intelligent Video Analytics". IVA refers to a system that analyzes images using AI with advanced processing power.

Types of business/industries where IVA can be used

IVA is expected to be active in various fields, but it can be used to solve problems in the following industries and industries.

 

・製造業

・建設、建機業界

・社会インフラ(空港、道路、鉄道)

・小売業

・飲食業

・Hotel

Such

Problems that IVA can solve

The following six representative examples are introduced as problems that can be solved by usingIVA.

課題:品質低下を引き起こす異常行動の検知

   不審者の発見           

解決:AIによる不審な「行動」の検知

 

製造業の現場では、品質低下につながる異常行動をなくしたいといった声や、小売業・ホテルでの防犯対策として、不審者の発見や、犯罪を未然に防止したいというご要望があります。

AIのアルゴリズムに不審な動きを検知できるモデルを搭載することで、従来の防犯システムでは検出が難しかった「行動」の異常を検知することが可能です。

課題:目視検査の品質ばらつきをなくしたい

解決:AIによる外観検査の自動化

 

When checking the quality of products in factories, visual inspections are still often performed rather than computer-assisted inspections for chemicals, automobile parts, and the like. In response to the issue of preventing quality variations due to individual differences, AI can be used to automate appearance inspections to improve quality and achieve stability.

(2) Labor shortage/removal of labor costs

課題:製造ライン/小売店/建設現場の人員を減らしたい

   属人化している業務の作業レベル不足を解消したい

解決:AIによる機器の自立化・自動化

 

As the declining population in Japan has become a social problem, more and more people are facing issues such as labor shortages, human resource development, and labor cost reduction. By digitizing not only simple work but also skilled technology through the evolution of AI, it is possible to support the operation of unskilled workers, improve productivity, and reduce the number of personnel as a result.

③ Ensuring safety

課題:危険エリアや制限されたエリアへの侵入を検知したい

   鉄道線路への転落を未然に防ぎたい

解決:AIによるエリア内の人物検知

 

In manufacturing plants and construction sites, there are places that pose a danger to the human body, and there is a demand to sound an alert when a person intrudes into that area. In addition, in order to prevent falls and collision accidents at airports, roads, and railways, it is possible to specify an area in the image of the surveillance camera and detect people in that area. Conventional sensors sometimes falsely detect animals, but AI analysis can accurately detect people.

④ Operational efficiency

課題:頻繁に入れ替わる従業員の管理が難しい

   入退出の管理を効率化したい

解決:AIによる顔認証・属性分析

 

In places where a large number of employees enter and exit on a daily basis, entry and exit may be permitted only in designated areas, making entry and exit management difficult. With the latest AI, face recognition and attribute analysis are easy, it does not take time to create a huge amount of data, and it is possible to easily create data for authentication by extracting from group photos and videos when people go to work.

⑤ Alleviation of congestion

課題:車の交通渋滞を解消したい

   人の混雑状況を把握したい

解決:AIによる交通量・人数の把握

 

There is a movement to prevent accidents by visualizing traffic congestion with AI based on camera images and changing traffic lights according to traffic volume. In addition, it is expected to be used in various ways to improve user satisfaction by grasping the congestion status of hotels and hospitals and avoiding busy hours.

⑥ Creation of added value

課題:来店者の属性や導線の情報をマーケティングへ応用したい

解決:AIによる属性・行動分析と既存データを組み合わせる

 

Based on the accumulated video data, it is possible to analyze the attributes and behavior of visitors. By combining the analysis results of attributes, length of stay, and line of sight with conventional environmental data and member information, we will pay attention to the possibility of creating added value such as reviewing products and shelf layouts and understanding peak hours for retail stores. are gathering.

IVA can be easily introduced into existing systems

Many people should be interested in IVA because it can be used to solve various problems. So what kind of equipment is needed to actually introduce IVA? Assumed customer's existing system is as follows.

 

既存システムの機材

・カメラ  (入力)

・モニター (出力)

・ビデオレコーダー (記録)

・インターネット環境 (通信)

・電源

 

If you have this equipment, you can actually easily introduce IVA.

Add AI package product to IVA introduction

IVA installation is completed just by adding AI package products. AI packages include pre-trained AI models and NVIDIA GPU-embedded servers to process them. AI models can be selected according to the application, for example, face recognition, attribute analysis, behavior analysis, people counting, route analysis, traffic volume survey, etc.

Before considering introduction, would you like to know how not to end with PoC?

In this article, I explained what IVA is, the challenges it can solve, and the introduction. If you have a problem that is not listed in the example, or if you are thinking of a completely new attempt, please feel free to contact us if you are even slightly interested.

 

In addition, as a video series that can be understood in 10 minutes, "PoC is not enough! Secrets of introducing AI image analysis" is released free of charge.

 

In this video, you can learn about common PoC failures and how to avoid them, so it is recommended for those who are considering introducing an image analysis solution using AI, or for those who have interrupted a PoC that started vigorously. is. Please take a look at this as well.
