Embodiment approach 1

[0034] [structure]

[0035] first reference Figure 1 ~ Figure 3 The configuration of the distance measuring device according to Embodiment 1 will be described.

[0036] figure 1 It is a diagram for explaining the outline of the distance measuring device 100 according to the first embodiment. figure 2 It is a diagram for explaining the distance measuring method executed by the distance measuring device 100 according to the first embodiment. image 3 It is a block diagram showing the characteristic functional configuration of the distance measuring device 100 according to the first embodiment.

[0037] The distance measuring device 100 is a device for measuring a distance to an object. Specifically, the distance measuring device 100 emits the outgoing light 300 toward the object, and the reflected light 310, which is the light obtained by reflecting the outgoing light 300 on the object, is detected by the imaging unit 110 having a plurality of APDs (Avalanche Photo Diodes,...

Embodiment approach 2

[0159] The distance measuring device according to Embodiment 2 will be described below. In addition, in the description of the distance measuring device according to Embodiment 2, the differences from the distance measuring device according to Embodiment 1 will be described as the center, and the same configuration as that of the distance measuring device according to Embodiment 1 will be described. The same reference numerals are attached, and explanations may be partially simplified or omitted.

[0160] [structure]

[0161] Figure 10 It is a block diagram showing the characteristic functional configuration of the distance measuring device 101 according to the second embodiment.

[0162] Like the distance measuring device 100 , the distance measuring device 101 includes an imaging unit 110 including a plurality of pixels each having an APD 111 , and is a device for measuring a distance to an object. The distance measuring device 101 includes an imaging unit 110 , a light ...

Abstract

This distance measurement method comprises: a step (step S300) for measuring the brightness of background light in an environment in which an object is illuminated by the background light; a step (step S310) for setting a distance measurement range on the basis of the brightness of the background light; a step (step S320) for setting, on the basis of the set distance measurement range, imaging conditions for an imaging unit including a plurality of pixels each having an avalanche photodiode (APD) and emission conditions for emitting light from a light source; and a step (step S330) for measuring the distance to the object by controlling the imaging unit and light source on the basis of the set imaging conditions and emission conditions.

Description

technical field [0001] The present disclosure relates to a ranging method, a ranging device, and a program. Background technique [0002] Conventionally, there has been a distance measuring device that uses light such as near-infrared light to measure the distance to a target object (for example, refer to Patent Document 1). [0003] A radar device as a distance measuring device described in Patent Document 1 includes: a laser diode that irradiates an irradiated light to a target object; A first light receiving circuit and a second light receiving circuit for signals; and a CPU (Central Processing Unit, central processing unit). In addition, the CPU generates an active area (energy range) which is a range of outputable light quantity values ​​among signals proportional to the light quantity values ​​of incident reflected light based on the two signals respectively output from the two light receiving circuits. Composite signal that is wider than the original 2 signals. [...
