Data processing method and device for setting light supplementing lamp set through light tracing

Abstract

The invention discloses a data processing method and device for setting a light supplementing lamp set through light tracing. The method comprises the steps of determining parameters and a monitoringdistance of a camera; preliminarily setting a corresponding light supplementing lamp group according to the parameters of the camera and the monitoring distance; determining a light distribution curveand radiation flux of the light supplementing lamp group; obtaining a corresponding view field according to the parameters of the camera and the monitoring distance; determining a corresponding target according to the field of view; performing light tracing on the light distribution curve and the radiation flux of the light supplementing lamp group to obtain a tracing result, and then obtaining the radiation flux on the target; and according to the tracking result and the radiation flux on the target, adjusting the current of the light supplementing lamp set, the angle of the light supplementing lamp and the number of the light supplementing lamps. The purpose of designing the camera lamp panel can be achieved through simulation, so that whether a light supplementing lamp set scheme of model selection is feasible or not can be predicted in advance, repeated material preparation cost and process can be saved, frequent outdoor tests are reduced, and a project plan is controllable.

Description

technical field [0001] The present application relates to the field of optics, in particular, to a data processing method and device for setting supplementary light groups through ray tracing, which are applicable to the fields of security monitoring, building intercom and smart home. Background technique [0002] At present, the night vision supplementary lighting solutions for security monitoring, building intercom, and smart home industry-related products can be divided into: 650nm, 730nm, 850nm, and 940nm according to the spectrum. The specifications of LED supplementary light selection rely on experience or mechanized reference of similar products. As a result, LED selection has great limitations and inaccuracies, and generally faces the following problems: [0003] 1. Shading: the housing blocks the light from the light source, resulting in insufficient LED fill light [0004] 2. Reflection: due to the design and selection of the primary lens or secondary lens of the...

Problems solved by technology

[0003] 1. Shading: the housing blocks the light from the light source, resulting in insufficient LED fill light

[0004] 2. Reflection: due to the design and selection of the primary lens or secondary lens of the LED, the angle is too large, resulting in the problem of rain cover reflection;

[0005] 3. The spot angle is small: the lens angle of the LED is too small, resulting in a small spot, that is, the center is bright and the surrounding is dark;

[0006] 4. Low radiation flux: Due to the low radiation flux, it is difficult to see objects at a distance from the target under night vision conditions.

[0007] Based on the above, the camera light board needs secondary design or even multiple designs, which wastes a lot of time and material costs for scientific research institutes and enterprises.

[0008] For many technical problems in related technologies, the industry has not yet proposed effective solutions
