Recently , Saitemei Co . , Ltd . announced that a new car infrared product production line has been put into operation in Shenzhen . The company ' s annual production capacity has increased from 150000 units to 1 million units , significantly improving overall product performance and production efficiency
The staff operates an automated production line for car mounted infrared products .
On March 29th , the relevant person in charge introduced to the reporter that this is the first automated production line for automotive infrared camera AA ( active focusing technology ) in China , which can achieve fully automatic , high - precision , assembly and production of dual 6 - axis optical systems , AA focusing , and automated testing of multiple functions .
Camera with visible temperature
Comparison of visible light and infrared recognition effects in the same scene
Established in 2016 Saitemei Security Electronics Co. Ltd. is committed to applying far - infrared technology to intelligent vehicles relying on the group ' s technological and industrial advantages . Its main products include advanced intelligent driving systems and intelligent cabins with in car infrared cameras being its representative products
In complex scenarios such as insufficient night light fog and rainy days most vehicles face the risk of failure in their intelligent driving functions The relevant person in charge of Saitemei Company demonstrated on - site and told reporters that the in car infrared camera converts invisible infrared radiation into visible thermal images . Due to the longer wavelength of infrared than visible light and stronger penetration it can still be "visible" in various complex scenarios "The infrared camera in the car can see the characteristic of 'temperature' and can keenly identify living organisms such as humans and animals effectively reducing the risk of accidents
In recent years , infrared sensors have been assembled in mass - produced cars by numerous domestic and foreign car companies to compensate for the shortcomings of traditional sensors in scene applications . It is reported that as the first car mounted infrared manufacturer to achieve mass production , it has successively launched the first domestically produced car mounted infrared thermal imaging product in commercial vehicles , passenger cars , and other fields . The related products have been applied in the mass - produced models of heavy - duty trucks and other vehicle companies .
" Car mounted infrared cameras can adapt to the needs of unmanned intelligent driving , and unmanned intelligent driving also requires infrared technology to improve safety ." The relevant person in charge of Saitemei said that currently , car mounted infrared products can meet the technical needs of autonomous driving ( L4 level intelligent driving ) . By installing one car mounted infrared camera at the front end of the vehicle , effective targets can be perceived up to 400 meters away .
In the introduction of the relevant person in charge , " military grade quality " has become a frequently mentioned keyword . It is reported that only in the cold and hot shock experiment , the relevant onboard infrared products can continue to be used normally after more than 600 cold and hot cycles in the temperature range of - 40 ℃ to 95 ℃ , meeting the usage needs of intelligent vehicles in different regions and more diverse scenarios .
"' Military grade ' infrared sensors are gradually emerging from the military industry and being applied to various types of vehicles ." The relevant person in charge said that due to high technological barriers and high costs , infrared sensors were previously mostly used in military vehicles and high - end cars . With the advancement of technological breakthroughs and market expansion ,' in the future , infrared sensors will be integrated with various types of sensors to complement each other's advantages and jointly improve the intelligence and safety level of cars . "
The core links of the production line are self - developed by the enterprise
" Products like car mounted cameras , which are relatively precise , can easily lead to inconsistent product performance during manual assembly . After being included in the AA automated production line , it can effectively improve product yield ." The relevant person in charge of Saitemei said that the application of good products cannot be separated from the support of intelligent manufacturing .
In the production process of traditional car mounted visible light cameras , AA technology and automated line production are very common . It is reported that AA technology is a technique used to determine the relative position of components during the assembly process , which can ensure the parallelism of the image sensor and lens , as well as the intersection point position of the optical axis and the image plane , thereby ensuring the effectiveness and accuracy of the camera product .
The newly launched production line has achieved nationwide industrialization , with the core link being independently developed by the enterprise . The relevant person in charge introduced that due to the differences in imaging principles between infrared cameras and traditional visible light cameras , there is currently no professional AA cable manufacturer in China that produces infrared cameras . We have independently designed the optical environment required for automated production lines , as well as related focusing and detection algorithms , in line with international advanced manufacturing technology .
" The fully automated focusing and assembly of the lens greatly improves the analytical power and assembly efficiency of the product . The accuracy of the optical axis center deviation is controlled within 3 pixels , while also taking into account the clarity of the visible field angle edge at the center of the field of view ." The person in charge said that the independent and controllable core technology ensures the production capacity , efficiency , and quality of the product , meets the requirements of first tier car companies for advanced manufacturing , and can accelerate the large - scale production and application of in car infrared .
In the transformation of high - end , intelligent , and automated manufacturing , new quality productivity is continuously being cultivated in factories , accelerating their advanced manufacturing capabilities . The person in charge introduced that the company currently not only has the " first " production line in China , but also has landed the first fully automatic comprehensive testing system for car mounted infrared products in China . The manufacturing process has achieved automation of nearly a hundred production processes , and the overall automation rate of the production line has reached over 90%. " In a few days , a new fully automated production line will be put into operation in the factory again ."
