Nowadays, the development of artificial intelligence is very rapid, which further promotes the development of visual technology. In industrial automation technology, visual technology is a very important key factor. In contrast, the industrial camera market is very bleak.
But with the market booming, in stark contrast to this is the overall fierce competition in domestic industrial camera prices, the hardships of the machine vision industry practitioners, especially the technology-oriented vision company, whose engineers are not debugging at the customer, or On the way to customer debugging, is this really proportional to the return? So, in the machine vision industry, it really is "I guess the beginning, but I have not guessed this ending." Of course, it’s too early to say that the ending is just around the corner!
The fire is on fire, but Marx has long taught us to "see the essence through phenomena." In such a hot market, we must think about why the price competition of industrial cameras is so fierce? The price of a 5 million CCD camera is more than 50% lower than five years ago, and it’s miserable! If industrial cameras are really valuable for high-end manufacturing, then in addition to the fierce price competition, is it still effective?
To understand this problem, we must first define two basic concepts, first, what is machine vision, and second, what is an industrial camera. The definition is clear in order to avoid detours. Turning a lot of literature, I feel that the definition of AIA is relatively simple and clear. First, Machine Vision (MV) refers to "industrial guidance for devices based on image acquisition and processing functions for industrial and non-industrial applications combined with all hardware and software." Industrial cameras refer to "an imaging device for a machine vision system that includes an imaging sensor chip and various electronic-based functions that convert a visual image of an object together into an electronic pulse." Sorry, the translation level is like this, let's just look at it.
Think carefully, in fact, these two concepts convey very important information. Machine vision is ultimately an application-oriented technology, which is driven by market and application requirements. Machine vision itself requires a complex hardware and software system. Support, which includes customer specific application requirements, software, industrial computers, industrial cameras, lenses and light sources. Please refer to Figure 1 for a schematic diagram of Baumer.
Figure 1
The figure conveys two signals. First, the core value of industrial camera products is not how low the price itself is, or how much money is saved for the customer, but as a key imaging technology and image processing software. Hardware carrier, how much utility or value can be brought to solve customer problems and applications. Second, if you want to do industrial camera sales or market, if you only understand low-price competition and don't understand customer needs in depth, we can say that this is irresponsible, at least for the customer to achieve maximum utility. So, where is the most direct effect of industrial camera performance? Excellent image quality? Excellent signal to noise ratio? High frame rate and high resolution? In fact, for industrial cameras, these are not things, otherwise they are really not qualified to call them industrial cameras. The most important thing is actually very simple and must be stable! stable! stable! Sorry, important things are said three times. Of course, to do this, companies must avoid vicious competition and have the ability and financial resources to continue to invest in product development.
Why do you say that? To be straightforward, if an industrial camera works 24 hours a day, there are no basic problems such as dropped calls and dropped frames, and it can be perfectly compatible with other electrical equipment on the site, which will undoubtedly greatly improve the detection efficiency of machine vision. Engineers will save a lot of time for more valuable technology development, rather than “always on the roadâ€. When machine vision machines are efficiently transformed into real-world productivity, “artificial intelligence will become a new engine for economic developmentâ€. It is a dream.
Of course, as an application-driven product, I have to admit that the price elasticity of industrial cameras in some industries is very large. If there is not much demand for the frame rate and stability of industrial cameras, the image noise is more or less. Does not affect the detection, then this industry will inevitably become a red sea, a large number of homogeneous substitutes appear, users care more about how much money can be saved and short-term fast returns, the final outcome must be price convergence. To be in these industries, I am sorry, I can only play when I can play.
However, when we return to the defining nature of industrial cameras and machine vision, we will find that there are always some industries that recognize the value of industrial cameras as a carrier of technology and applications. They are willing to use them, that is, by consuming such The degree of satisfaction generated by goods and services to pay higher prices. As an industrial camera provider, we must also think about how to maximize the utility of industrial cameras in the industrial field to obtain recognition. Here is an example of a Baumer industrial camera that is not modest. We have been climbing the peak here (it is absolutely mountain climbing here, and Baumer’s flag is the highest at Manaslu Peak at 8163 meters above sea level). From the product itself, Baumer industrial cameras currently use mainstream CMOS sensors, which are constantly close to customers in product features and function development, and deeply understand customers' demands for industrial applications. As far as the industrial site is concerned, we have found several main features: 1. The environment is complex, and many sites should consider how industrial cameras work stably under conditions of humidity, dust, and strong electromagnetic interference. 2. Industrial equipment for different application requirements, should consider the camera power supply, compatibility with other equipment (such as PLC, PC), camera interface, compatibility with client software and so on. 3. The working mode of the camera needs to take into account the specific state of the detected object, especially to understand the true requirements behind the customer's testing requirements, how to control the camera for high-speed motion shooting, and how to achieve stable and trouble-free shooting.
First of all, in terms of protection level, Baumer industrial cameras have specially developed a wide-temperature camera with IP67 protection for customer applications. The working environment temperature can reach -40 °C to + 70 °C, and the camera integrates a temperature sensor. Monitor camera temperature in real time. In addition, the cameras are specially tested for harsh environments and can withstand up to 100g of shock and 10g of vibration.
Secondly, for industrial field power supply, Baumer adopts a wide voltage supply mode of 8-30V DC. The camera triggers a filtering design such as debouncer to ensure that the camera can receive the trigger signal stably without interference from the scene. In order to ensure the temperature of the high-precision measurement data, all of Baumer's camera sensors are packaged on the heat sink. Good heat dissipation ensures low noise and good data time drift.
Again, for particularly demanding inspection requirements, for example, Baumer has released a series of products with the shortest exposure time of 1us based on the SONY Pregius chip, ensuring clarity and contrast for taking pictures of high-speed moving objects. For big data transmission, Baumer has developed a 12 million resolution camera based on 10GigE (10GigE) interface with a maximum frame rate of 335fps and 2GB of internal storage. For fire-fighting 3D applications, Baumer also introduced a 3D camera based on FPGA programming, which has a dedicated pre-installation program for laser triangulation. Thereby, the focus of the laser line can be positioned with sub-pixel accuracy within the camera to transmit only the contour data, thereby greatly reducing the amount of data that needs to be transmitted. With a resolution of up to 12 megapixels, a distribution ratio of 2.5 kHz at 4K line width and 128 lines, the camera reliably recognizes the slightest deviations and the like even at high processing speeds.
In short, everything we do is only trying to maximize the utility of industrial cameras in machine vision, and to say that it is a small force for China’s advanced manufacturing, and to say that we want Baumer industrial cameras. Providing a user-friendly experience and eliminating the need for engineers to spend energy and time due to hardware instability is a huge cost to the enterprise. From this we believe that there will always be one day, our beloved visual engineers will not be so hard, the ear can be less the sound of the industrial computer, and do not have to face the screen full of sweat all day long; whenever Flying birds into the forest, looking up to see the smoke in the house.
