An inspection tunnel for illuminating an outer surface of an object to be inspected, comprising a frame with an arch shape of the inspection tunnel; light sources distributed on an inner face of the frame, configured for illuminating the outer surface of the object; a light diffusing screen with an arch shape and extending in front of the light sources; wherein the light diffusing screen contacts at least some of the light sources.

The invention relates to a method for inspecting a coated surface for a surface defect. The method comprises: using (102) a device (200, 300, 400, 700, 800, 900) for covering the coated surface to be inspected, the device being configured to create an enclosed space to isolate the surface coating to be inspected from ambient illumination in order to provide predefined photographic acquisition conditions within the enclosed space; acquiring (104) a photo of the coated surface being within the enclosed space; and inspecting (106) the photo for the presence of the surface defect.

In one embodiment, systems and methods include using a workforce augmenting inspection device (“WAND”) to measure a parameter of an aircraft. The WAND comprises a body, wherein the body comprises one or more buttons configured to actuate the WAND to perform one or more functions. The WAND further comprises a head comprising a camera and a light source, wherein the light source is disposed around the camera operable to produce light in conjunction with operation of the camera, wherein the camera is operable to capture an image within a scope of view of the camera. The WAND further comprises a standoff wheel, wherein the standoff wheel is operable to rotate independently of the head. The WAND further comprises a power source operable to provide power to the WAND, wherein the power source comprises a controller configured to actuate the head, camera, and light source.

The disclosed technology relates to an inspection apparatus that includes a stage configured to retain a specimen for inspection, an imaging device having a field of view encompassing at least a portion of the stage to view a specimen retained on the stage, and a plurality of lights disposed on a moveable platform. The inspection apparatus can further include a control module coupled to the imaging device, each of the lights and the moveable platform. The control module is configured to perform operations including: receiving image data from the imaging device, where the image data indicates an illumination landscape of light incident on the specimen; and automatically modifying, based on the image data, an elevation of the moveable platform or an intensity of one or more of the lights to adjust the illumination landscape. Methods and machine-readable media are also contemplated.

A nano projection structure inspection apparatus herein disclosed includes an inspection light irradiation part and a chromameter. The inspection light irradiation part irradiates inspection light to an inspected surface being a surface of a metal. An imaging optical axis of an imaging element of the chromameter is arranged to be tilted to a regular reflection direction of the inspection light caused by the inspected surface. The chromameter makes the imaging element receive diffusion reflection light, among reflection light of the inspection light from the inspected surface, the reflection light containing regular reflection light and the diffusion reflection light, so as to inspect a nanoscale projection structure on the inspected surface.

A method to minimize applying joint compound and sanding by illuminating an area of the gypsum board to show anomalies thereon includes a step of providing a plurality of wireless lighting devices operable by a common remote controller, a step of removably attaching these devices in a spaced-apart arrangement and using the remote controller to energize all lighting devices to identify remaining anomalies. All lighting devices are turned off once the next coat of joint compound is applied and then turned on after it dries to illuminate the remaining surface anomalies. Operation of lighting devices is accomplished without removing or repositioning thereof to assure consistency of illumination over the entire work period.

The present disclosure generally relates to a system for optical inspection of an object, specifically comprising an illumination assembly operated to provide homogeneous illumination of the object, thereby improving the overall accuracy of the optical inspection. The optical vision system also comprises an image sensor configured to capture an image of the object and a control unit in electrical communication with and configured to operate the image sensor and the illumination assembly, wherein the control unit is configured to automatically control the illumination assembly to illuminate the object with a predetermined illumination pattern based on a selected object type. The present disclosure also relates to a corresponding method and to a computer program product.

A fused imaging device and method are disclosed. The device comprises a light source component, an image capture component, and a control component. The control component may be configured to control the light source component to illuminate a target object based on a preset plurality of first optimal lighting configurations. The control component may further control the image capture component to capture images of the target object to obtain multiple first images, under the illumination of the light source component and generate a target image of the target object, based on the first images. The control component may further adjust the incidence angle, pattern, and wavelength of the light source in the light source component, as well as the exposure, lens focus, and polarization of the image capture component, to detect target object defects in captured images of the target object.
