Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of visual detection of smoke range, in particular to an image acquisition device for visual guidance of smoke range. BACKGROUND

[0002] Nowadays, with the gradual improvement of people's living standards, many intelligent household appliances are gradually favored by people, among which the range hood has become a standard in every family kitchen. At the same time, as users' requirements for household appliances are getting higher and higher, the types of functions of many household appliances are getting more and more. At present, almost every family has equipped an oil smoke exhaust machine in the kitchen to improve the quality of people's kitchen life. With the development of technology, the smoke machine is becoming more and more intelligent. In the current market, in order to save the operation space of the kitchen, many users choose the smoke range all-in-one machine. The smoke machine rises from the smoke machine cabinet when working, and falls into the smoke machine cabinet when not working or on standby

[0003] Image acquisition is a stage that must be experienced in the image processing process, but the acquisition of high-quality and high-information images often requires high technology. At present, the methods for collecting kitchen range hood oil smoke images mainly include infrared projection method and physical detection method, but both methods have disadvantages. The infrared transmission method has high requirements for installation position and is inconvenient to install. The physical detection method is not suitable for long-distance detection and has large delay.

[0004] The application number CN201811151549.5 and the application name are a collection method and device for kitchen range hood oil smoke image, and the technical solution recorded in the application collects very clear kitchen range hood oil smoke image information through pure infrared light compensation and a wide-angle lens equipped with an optical filter. Then the image pre-processing unit crops the obviously distorted image edge area collected by the wide-angle lens. The collection method of the kitchen range hood oil smoke image is not affected by the detection distance, realizes non-contact real-time detection of oil smoke concentration, reduces the cost of collecting high-quality images, and has the characteristics of high accuracy, but still has some deficiencies, such as inconvenience in adjusting the collection position during image collection, and easy to be disturbed during collection, affecting the accuracy of collection. Therefore, we propose an image acquisition device for visual guidance of smoke range. SUMMARY
