Problems solved by technology

Even with the correct formulation and the paint components the formulation calls for, the final result will depend in part on the skill used to measure and blend the components, which can lead to deviations from the target color

Embodiment Construction

[0025] Several related concepts are described herein that reduce or eliminate known disadvantages of the prior art. These concepts can be used independently of each other or in combination.

[0026]The time to prepare a suitable paint or coating can be reduced by taking measurements of the damaged car before it reaches the repair shop, and then communicating those measurements to the person or persons responsible for the paint formulation. This can be done at the accident scene or at the accident investigation site, to which the damaged car can be moved after the accident. figure 1 An exemplary coating measurement process 1010 is illustrated in . The steps involve: reaching the location of the damaged car 1012, determining one or more locations to be measured near the damaged surface of the car 1014, and cleaning the selected locations 1016 where color / appearance measurements will be taken . Typically, these points will be located at the undamaged location closest to the da...

Abstract

A mobile device for measuring reflectance properties of a surface includes a first imaging device comprising an image sensor and a lens characterized by an optical axis; a first illumination source having an optical axis disposed at an angle of 45 degrees with respect to the first imaging device lens' optical axis; a second imaging device comprising an image sensor and a lens characterized by an optical axis; and a second illumination source having an optical axis intersecting the first imaging device lens' optical axis where the first illumination source intersects the first imaging device lens' optical axis, the optical axes of the first imaging device and the second illumination source defining a second measurement plane. The mobile device further comprises a computer processor and a non-volatile memory comprising computer-readable instructions to acquire data from the first and second imaging devices and derive reflectance information of the surface of interest.

Description

[0001] related application [0002] This application is based on, and claims the benefit of priority from, US Serial No. 62 / 501,036, filed May 3, 2017, and US Serial No. 62 / 501,434, filed May 4, 2017. Background technique [0003] The field of the invention relates to matching automotive paint and / or coatings for use in repairing damaged vehicles. The paint color of an automobile often has a corresponding color code that defines the appearance of the paint as originally applied. For example, BMW paint code A76 is a metallic paint with the name "Deep Sea Blue". Paint codes are often stamped on the body panels of cars. Additionally, paint chips may be included in the vehicle's owner's manual. [0004] Even with such paint code information, it is difficult for several reasons to produce a new paint that is a good match to an existing paint for repair purposes without accurately measuring the appearance of the paint to be matched. First, paints corresponding to the same paint ...
