Embodiment Construction

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0046] An embodiment of the present application provides an image processing method, which is applied to an image processing device, such as figure 1 As shown, the method includes the following steps:

[0047] S101. Acquire a first image with a first object.

[0048] Wherein, the first image is a height map, and the height map includes height information of the first object; the pixel value of each pixel in the height map may also be referred to as a height value.

[0049] In a feasible implementation, if the first image is a 16-bit (16-bit) height map, at this time, the pixel level is 65536 (2 to the 16th power), and the value range of the pixel value can be 0 to 65535 , each pixel level represents a different height.

[0050] In the embodiment of the present application...

Abstract

The embodiment of the invention discloses an image processing method. The method comprises the following steps: acquiring a first image with a first object, wherein the first image is a height map; performing conversion processing on the first image to obtain a second image, wherein the second image is a grey-scale map; and determining whether the first object is abnormal based on the first image, the second image and the target image. The embodiment of the invention also discloses an image processing device.

Description

technical field [0001] The present application relates to image processing technologies in the field of image processing, and in particular to an image processing method and device. Background technique [0002] During the production process of the keyboard, multiple screws need to be locked. Usually, the screws on the keyboard are locked by a combination of automatic screw machine and manual; due to the technical limitations of the screw machine and the lack of manual locking ability, there will be abnormal screw locking. , The main performance is that the screw lock is not in place, the screw floats high, the screw lock is missing, and the screw head is twisted. In order to detect whether the screw lock on the keyboard is abnormal, in the related art, a laser profiler is used to scan multiple screws locked on the keyboard to obtain a height map and a brightness map for multiple screws. Through the height map and brightness map of multiple screws To detect whether the scre...
